Roofing Tips For The Winter

by with No Comment Roof RepairRoof SystemsRoofing Services

Winter is definitely here in Vancouver and as you all know, the harsh conditions can cause damage and decrease the longevity of your home’s roof. If your roof needs repairs, it’s generally better to do them in the drier months. In fact, most experts say the best time to do work on a roof is from July to August when the weather is best. In a perfect world, summer would be great to finish all those projects, but your roof doesn’t just leak during those months.
Moreover, In British Columbia, where the weather is often unpredictable, these ideal conditions can be few and far between. Most roofing companies have to consider how they can perform a roofing job in the winter, in less than ideal conditions.
While not always the best, roof construction and repair can be done in cold weather, as long as precautions are taken. In winter, roofers face a variety of challenges including:

  • Roofing materials don’t work quite as well as they do in moderate temperatures.
  • Shorter days give roofers less time to work which generally means the project takes longer.
  • Tools such as nail guns generally don’t work as well in the cold.
  • Snow and ice can create hazards or cover up dangers to roofers.

What to Expect When Roofing in Winter

Roofing in winter weather requires a lot more foresight, planning and safety precautions than summer days. Be aware that some companies will charge you up to 20% more for their services, while other companies will be looking for work and might give you a discount. Whatever you do, you should shop around and get between three to five quotes and ask them specifically about their winter work.

Winter Safety Is The Most Important

Safety is obviously the most important thing when it comes to roofing – no matter what time of year. Under no circumstances should you hire a company that doesn’t take safety serious as there are some unique cold weather issues to be aware of when doing winter roofing work.
For example, roof surfaces can become slippery thanks to snow, ice, and frost. A common winter problem is snow removal or de-icing of the roof surface must be done after a snowstorm. The roofers must take extra precaution and use specialized equipment, which they need to be trained on, along with increased monitoring while the removal is taking place.

Snow can also disguise dangers such as skylights, debris and other risks. The roofing contractor needs to pay close attention to where they walk to ensure they don’t accidentally step on or fall through a skylight or trip over hazards hidden under snow. Even on a freshly cleared roof, there may be black ice or frost build-up on the roof or deck surface, which can make work extremely dangerous. If the temperature is too cold and the snow and ice remain, it is best to wait until the weather warms up.
Another thing to do before getting a roofing contractor to work is to ensure that the attic space is adequately air-condition. Often, what appears to be a roof leak is actually condensation from interior air drifting up into a cold, improperly ventilated attic.

Working in the Winter

Working in cold, damp temperatures can put a strain on the body, making your heart and lungs work harder, while at the same time putting you at increased risk for hypothermia or frostbite. Be aware roofers, as mentioned before, will work shorter hours, and plan around the sunshine and weather forecasts. Be prepared for work stoppage and delays because of the weather.
Roof contractors should also wear warm clothing that is breathable but also provides an ample range of motion. If you notice that a roofer isn’t appropriately dressed, do not let them work.

The Weigh Of Your Roof

Another thing to consider is the extra weight that snow and ice can add to a roof. If you add a human’s weight into the mix, you can potentially be looking at serious injury. A roofer must ensure that the surface he is working on is sturdy and safe from collapse. An experienced roofer will test the structure before beginning to work on it to ensure that there is no danger from collapse.

Equipment and Materials

Now you know what to expect in the winter, you also have to keep in mind the quality of craftsmanship which can suffer if the roofer is inexperienced.

Asphalt shingles

The best temperatures to install asphalt shingles is between 4 and 26 degrees Celsius. If a roofer decides to install roofing shingles in cold weather below these temperatures, your shingles may become brittle and more prone to breakage. To prevent this, when working in below-zero temperatures, make sure the roofer stores your materials in a warm place until you need them. Shingles will mould to the shape of the surface they rest on, so if you are buying them before using them, keep them flat, stacked and raised on pallets so they don’t touch the ground. Be aware that a roofer should not work in below-zero temperatures unless it is an emergency situation that needs fixing.

Types of Roofing Materials

Most roofing organizations recommend using winter weather membranes to seal your eaves, valleys, skylights, and vents, rather than warm weather roll roofing, which can buckle or warp when applied in cold weather. When you choose to use any kind of felt or membrane, the roofer will roll it out in a staging area, away from the elements and allow it to relax before you apply. This will help reduce wrinkles caused by the weather.

Conclusion

The information in this blog is purposeful to be a starting point for cold weather roofing applications. Each situation is different and as always consult a professional roofer before starting.

The Importance of Ventilation and Insulation in Asphalt Shingles

The Importance of Ventilation and Insulation in Asphalt Shingles

by with No Comment Roof Systems

Roofs need the right balance of both ventilation and insulation to work properly, especially with the type of weather we’ve been having in Vancouver the past couple of ears. In warmer weather, poorly ventilated roofs can result in hot attic spaces which can significantly damage shingles, causing curling or even breaking, reducing the lifetime of a roof.

In the colder seasons, a lack of ventilation can trap cold air and cause moisture to build up, resulting in problems with mold, rot, and mildew, which can damage the roof and walls. Properly ventilated and insulated roofs upon are important to protecting against the problems caused by seasonal extremes and avoid costly repairs. Just think of the leaky condo crisis that cost Vancouver over $4 billion in damages because buildings didn’t have the proper ventilation.

While in Vancouver ventilation was a problem with newer buildings, it is usually common in older homes, which were generally constructed when building codes did not require as much insulation.
As many Vancouver builders discovered, creating the proper ventilation and insulation of asphalt shingle roofs is isn’t always easy. You need to get the advice of an experienced, licenced roofer to do the job correctly.

Roof Ventilation

Proper roof ventilation reduces electricity bills, extends shingle life, and prevents roof rot and ice dams in winter. Doing it right the first time also protects your house from expensive future repairs. The most important aspect of roof ventilation is to ensure your roof has vents so that the excessive moisture can escape. Ventilation is required by building codes. If you don’t properly ventilate your roof it will likely void your roofs warranty.

The number of vents within roof space will depend on the size of the roof and the material used, however, the general rule is that a single vent should be enough for a squared 30-meter roof space. A specific number of vents are required per square footage to ensure that the right amount of air enters and exits the attic.

Roof Insulation

Insulation plays a vital role in ensuring your home is properly ventilated. While you need to have enough insulation to help your house efficiently maintain a comfortable temperature. It is just as important t that you do not have too much insulation in case it blocks proper air circulation.

An experienced roofer or contractor can decide what your home needs and advice you on the proper course of action. Of course any work a roofer or building contractor does on the vents needs to be done carefully. So you do not decrease the area of the vents or anyway stop the airflow.

You probably won’t notice if something is wrong with your roof’s insulation or ventilation which is why it’s important to have an experienced, trustworthy roofer do a checkup at least once a year. If there is a problem with the airflow, they will know and be able to fix it. Often the solution depends on what is causing the lack of airflow. In the simplest and least costly case, there may be something obstructing the vents which is an easy fix.

lack of ventilation

Unfortunately, in many cases, the lack of ventilation is caused by something more serious. Such as a lack of or inappropriate placement of vents. If that’s the case, you might need to rip up a part or the complete roof to fix it.
Insulation placed on an air-sealed attic floor is simple, yet one of the most underappreciated building assemblies. A vented attic works in all types of climates to keep the home regulated.

Same, unexperienced builders do not install insulation correctly. Which causes excessive energy losses, ice dams, mold, rot which all need to be fixed sooner than it should.

If your builder has properly ventilated your roof space, then you will have to keep the vents free. So they can allow for proper air flow. This means that the vents should not be obstructed otherwise the moisture will still stay trapped within the roof structure. And eventually turn into mold and rot the wood.

Using Vents In Your Roof

There is a variety of different vents to select from when choosing a new vent for your roof. Two of the more common vents you will find are the box vent and turbine vents. The box vent uses natural air flow to draw hot air out of the attic. However they are not as effective as turbine vents and you will require more of them to properly ventilate your space. Turbine vents are wind-driven and more effective.

There is a third type of vent which are called ridge vents. But they are not as common as the first two. They, as you might suspect, run along the ridge of your roof. Moreover, They keep a more consistent temperature across your roof than box vents. And do not require wind to operate like turbines.

They are slightly more expensive, but when used with soffits. The underside of the area which connects the roof to the wall, they will keep your space well ventilated.

Conclusion

Whether you are in need a roof inspection or have a leaky, it’s important to choose a roofing contractor that is trustworthy, reliable, and experienced. At Cambie Roofing we are experts in providing you the service you need within your budget. Give us a call or email us for a free estimate.

Ways Winter Impacts Your Roof

As winter descends upon the northern landscapes of Canada, homeowners face a unique set of challenges in ensuring their abodes stand resilient against the season’s frosty grip. Among the vulnerable components of a home, the roof stands as a silent sentinel, combating heavy snow loads, freezing temperatures, and a myriad of winter-related adversities. In this comprehensive guide, we will delve into the manifold ways winter impacts your roof and unveil effective solutions to safeguard your home during the colder months.

Heavy Snowfall and Structural Stress:

The picturesque snowfall that blankets your home can be enchanting, but beneath its beauty lies a potential threat. The accumulation of heavy snow on your roof poses a significant risk to its structural integrity. The sheer weight of the snow can stress the roofing materials and framing, leading to potential damage or, in extreme cases, collapse. This risk is especially pronounced for flat or low-pitched roofs. To mitigate this threat, proactive snow removal becomes crucial. Consider using a roof rake to safely clear excess snow or, for larger tasks, ask the professionals at Cambie Roofing for a snow removal referral, to alleviate the burden and preserve your roof’s resilience.

Ice Dams and Water Intrusion:

Winter’s fluctuating temperatures contribute to the formation of ice dams along the roof’s edge. These dams obstruct the natural drainage of melting snow, creating pools of water that may seep into your home, causing water damage. Proper insulation and ventilation in the attic are paramount to counter this issue. By maintaining a consistent temperature on the roof, you can thwart the conditions conducive to ice dam formation and prevent potential water intrusion. Adequate insulation also helps to minimize heat loss, reducing the risk of ice damming.

Freeze-Thaw Cycles and Shingle Vulnerability:

Winter’s relentless freeze-thaw cycles pose a unique threat to roofing materials, particularly shingles. The constant contraction and expansion can render shingles brittle, leading to cracks and vulnerabilities. A thorough pre-winter roof inspection is paramount to identify any compromised shingles and address them promptly. This proactive measure ensures your roof remains steadfast against the elements. Consider investing in high-quality shingles designed to withstand the rigours of winter, providing an added layer of protection.

Condensation Challenges and Attic Health:

Condensation and moisture issues within the attic space escalate during winter. Inadequate insulation allows warm air from your living spaces to infiltrate the attic, where it meets the cold roof surface, leading to condensation. This moisture can foster mold growth and compromise your roof’s structural integrity over time. Prioritize proper attic insulation and ventilation to create a barrier against these winter-induced challenges. Adequate ventilation allows for proper airflow, preventing the buildup of excess moisture and maintaining a healthy attic environment.

Gutter and Downspout Conundrums:

Winter poses unique challenges for gutters and downspouts, often leading to freezing and blockages. When not addressed, these issues can impede proper water drainage, causing potential damage. Regularly clearing debris from gutters and ensuring downspouts remain unobstructed are essential preventive measures. This not only protects your roof but also safeguards your home’s foundation from water-related issues. Consider installing gutter guards to minimize the accumulation of debris, reducing the need for frequent cleanings.

Final Thoughts

As winter casts its wintry spell, understanding the nuanced impact on your roof is crucial for homeowners in Canada. By proactively addressing the challenges of heavy snow loads, ice dams, freeze-thaw cycles, condensation, and gutter issues, you can fortify your roof against the elements. Embrace these solutions to ensure your home stands resilient and secure throughout the winter, weathering the challenges with grace and strength. A well-prepared roof not only preserves the structural integrity of your home but also provides peace of mind as you navigate the colder months with confidence.

Roof Warranties

The Ins and Outs of Roof Warranties

by with No Comment Roof Warranties

The Ins and Outs of Roof Warranties

Homeowners are often confused by warranties and their terms, which is compounded when a lot of roofing contractors don’t explain them adequately. Homeowners assume that when a product includes, for example, a 15-year roofing warranty, that everything to do with their roof installation will be covered for 15 years. Unfortunately, this isn’t always the case. More commonly, a warranty is limited to material costs only, and does not cover cost of labour and other costs associated with the removal and replacement of materials. When looking at roofing warranties always read the fine print and ask if you don’t know.
In fact, roofing warranties can be complicated and it’s important as the building owner that you understand what type of warranty covers your roof, the terms of the warranty, factors that may make the warranty void. In this post, we will demystify some of the issues that surround roof warranties.

 Types of Roofing Warranty

There are two basic types of roofing warranty which area the contractor warranty and the manufacturer warranty. Just as they sound, the contractor warranty is provided by the roofing contractor. That installs your roof whereas the manufacturer warranty is provided by the company that makes your roofing material. The type of warranty can vary significantly from one company to another, from one manufacturer to another. Typically, a contractor offers a warranty that covers labour while manufacturers’ warranties cover materials. Sometimes these warranties overlap, but that’s certainly not always the case. Just what kind of roof warranties do you need, and what does each kind actually protect you against?

While this is not a complete list, here are some of the basic warranties:

Labour warranties: This means the labour costs to remove and reinstall defective building materials. This does not always include the original installation. If leaks are due to workmanship errors with the original installation, a labour warranty may not cover this problem.
Material warranties: are fairly inexpensive but apply only to material defects that cause early deterioration of roofing systems. These Roof warranties include the roof membrane but not flashings, adhesives, or edges. A material warranty will cover the costs of material replacement but not the labour costs associated with repair.
Workmanship warranties: This type of warranty can be confused with a labour warranty. It is, in fact, a type of warranty that will cover you against costs related to actual installation failures and errors which a labour warranty may not cover. If you’re worried about sloppy workmanship, than this is probably the best warranty to purchase.

Terms of Roofing Warranty

As you may have guessed, the terms of your roofing warranty will depend on the type of warranty you have. and also the company providing the warranty. A thing to keep in mind is that the warranty is only as good as the company backing it.
It is important to note that there are typically maintenance responsibilities that are outlined in your warranty. If you fail to maintain your roof, your warranty may be deemed voided. For example, if you fail to fix curling shingles, the warranty may not be honoured. Additionally, roofing warranties are not likely to cover damage from standing water, damage to interior structures, and also so-called “Acts of God”. Acts of God are extreme weather conditions such as a floor, lightning, earthquakes, vandalism, or fire.

It probably won’t surprise you to learn that a lot of roofing warranties are more geared toward protecting the manufacturer than the homeowner. Manufacturers, of course, don’t want to shell out money to homeowners unless they really have to. Which is why they spend a lot of money on lawyers to compose the fine print that ultimately tries to limit their own liability if something goes wrong with their roofing products. That’s why it’s so important that you understand the following before signing off on your project and warranty purchase:

  • What type of roof warranty am I getting?
  • How long does the warranty last?
  • What can void my roof warranty?
  • What are my responsibilities for maintaining my roof warranty?
  • What doesn’t a typical roof warranty cover?

Manufacturer Warranty

The most common kind of manufacturer warranty is a shingle warranty which may cover you for 20 to 50 years. As described earlier, this type of warranty only protects you against defects in the roofing materials themselves, not against improper instalment or worker error.

Although having a manufacturer warranty is important for your peace of mind, it’s actually rare for a roofing problem to be traced to a manufacturing defect. More commonly, a substandard roof is attributable to poor installation which is a separate issue altogether and which a manufacturer warranty won’t cover. Keep in mind even if the materials themselves are at fault, your warranty may only cover those materials, not the labour required to install them.

Conclusion

The actual terms of a roofing warranty will differ from company to company and the roofing material you select. Always ask for a copy of the warranty before signing the contract. And educate yourself about the exclusions and limitations in the warranty.
When you hire a roofing contractor, you should first check to see if your roof is under warranty. If it is, then it can help you save possibly thousands of dollars in repairs. Call us at Cambie roofing because we offer you the most warranty choices for your new roof or roof repairs.

Repair vs Replace Your Roofing

Repair vs Replace Your Roofing

Repair vs Replace Your Roofing

Roofing is one of those tasks like replacing the alternator on your car – nobody wants to do it but sooner or later it has to get done. After all there are so many more fun tasks to be done around the home that are so much more satisfactory. Let’s see the difference between ” Repair vs Replace Your Roofing”
Roofs are prime targets for procrastination– what you can’t see doesn’t matter, right? Unfortunately, that isn’t true and those leaks, missing tiles and other issues have started to pile up so you might be wondering whether its’ time to fix them or invest in a new roof all together.

The question of whether to repair or replace isn’t always an easy one to answer because there a number of different factors to consider which we will cover in the blog post. The big one of course, is always the cost but before we get to that one, there are a few other things.

What Are My Plans For Your Home?

This is probably the most important question to ask yourself before spending money on your roof. Do you plan on spending a long time in your home or do you intend to sell it in the next couple of years? Nothing can stop a sale faster than a roof that’s in bad shape and in desperate need of replacement. Even if you’re pricing the home relatively modestly for roofing repairs, many people don’t want to deal with the hassle or stress of replacing the roof. Making an investment in your roof can actually help your property sell faster and get a higher value for it – more than the cost of replacement.

While an old roof can scare off potential buyers quickly, a new roof can just as quickly attract plenty of hopefuls. For those looking to move into a new property, not having to immediately invest in something major like a new roof is a huge benefit.

If you want to retire in your home and don’t mind waiting or dealing with the headaches that come with an old, damaged roof then you might want to consider putting off spending money on a new room. A word of warning, however: be prepared for the fallout that comes with not upgrading your roof including major water damage.

What Is The Nature Of The Damage?

The first question you need to ask is what is the extent of the damage to the roof. A single missing shingle or a small leak can be easy to fix. In fact, the sooner you do so, the less likely the damage will spread and will cost more.
Larger problems that are more widespread like a large hole or a leak that is flowing can be your signal that a roof replacement will soon be in order.

Visually inspecting your roof from both the inside and the outside can tell you just about everything you need to know about its condition. Start outside from the curb in front of your house. And look for any visible locations where the tiles or shingles are damage or missing. These areas are major weak points in your roof’s ability to withstand another winter and are most likely the sites of leaks that could be causing discolouration or signs of water damage on your ceilings.

Once you’ve checked around the outside of your house, climb up into your attic and take a look. You should be checking for any wet spots or water. Water damage can be a real problem as it can cause havoc both on your roof and the interior or your home. Signs of water intrusion include wood rot, mold and mildew growth. Another thing to look out for could be small cracks where light is shining through. Ultimately, you will need to get a roofer to take a look and give your professional opinion on whether or not these cracks, water damage, or mold warrant a new roof or if they can be patched up.

How Old Is the Roof?

Your roof’s age is another large factor in whether you should repair it or replace it. If your roof is still on the newer side, then repairing it is probably the better way to go. However, if your roof is old and has fallen into a state that no amount of repairing will really salvage, then replacing is definitely the optimal choice.

The expected lifespan of your roof depends on the material it’s built from. For example, in Vancouver asphalt shingles are common because they are inexpensive, lightweight, and easy to repair, but generally only have a lifespan of about 15 years. On the other hand, tiles, clay, and aluminum are much harder, more durable, and resistant to natural hazards and can last between 30 and 50 years or more in most cases. If your roof is approaching this age, then it may be time to consider replacing your roof and starting new.

What Is The Cost Difference?

Cost is obviously the first question wonder, but it shouldn’t be the major factor behind your decision making. If you’re a home owner you should be putting money away in a renovations fund each month to prepare for things like roof repair or roof replacement. If you don’t have the money, it’s not a good idea to go into debt to replace your roof unless it’s going to cause a large amount of damage to the interior of your home.

Conclusion

So, I hope you get an idea after this comparison “Repair vs Replace Your Roofing”. Unfortunately no roofing system lasts forever. Particularly in a climate as diverse as Vancouver’s’ and will eventually have to be replace. However, as a home owner, you should be able to stretch the lifespan for as long as possible. Roofing systems are important to the structure and protection of your home. It’s what keeps you dry, warm and safe from the elements. If you notice leaks, broken shingles or other problems with your roof, contact Cambie Roofing, a family owned & operated local roofing contractor with decades of experience in residential and commercial roofing. We’ll evaluate your roofing system and recommend whether you should repair or replace your roof.

How To Protect Your Roof From Pests

How To Protect Your Roof From Pests

by with No Comment Roof Repair

Many types of animals including birds, rats, insects and other pests can be a nightmare for homeowners, especially if they make your roof their home. They can have a significant negative impact on the quality and durability of your roof. Not only can their droppings make a considerable mess, but they also expose your home to parasites such as worms and mites. Let’s find out below about How To Protect Your Roof From Pests.

Large pests especially rats, raccoons and birds can also cause damage to roof tiles and shingles which not only make a lot of noise but can also cause costly repairs. Still, preventing pests from damaging your rooftop can be difficult. So what are some safe methods for protecting your roof from animals and, if you have them, how do you get rid of them.

Know the Signs of Infestation

The first step is to figure out if you have a problem to begin with.  Pests leave visible signs of their presence in a variety of ways. Once you know what to look for, it’s easy to tell if you’ve got unwanted animals in your attic or on top of your roof.

The first thing to do is a visual inspection of your roof. This can be done from the ground but it is better if you use a ladder for a closer inspection. Mammals like rats, squirrels and mice leave droppings wherever they go. Small pellets of feces are an obvious sign that rodents are near. Where there are feces, there is also urine.

If you look in your attic, you might not detect a smell immediately, but practice safety by using gloves and wearing a face mask before you poke around in areas where rodents have been. Their droppings can contain harmful bacteria.

Another sign to watch for chewed areas, holes or tunnels bored in the attic or roof. Rodents and insects often chew their way through wood, plaster and other materials.

Pest Removal Methods

Depending on what type of pest you’re dealing with, different methods may be more effective. Here are some common removal methods that could help you get rid of those pesky animals.

Trapping: Using a trap and some food is a great way to catch unwanted pests inside and around your roof. This is a common method for rodents such as mice and rats.

Decoys: Placing plastic statues of predators, like owls and hawks on your roof are a great way to trick birds into staying away and can prevent them from starting a nest.

Destroy The Nest: If birds are constantly trying to make your home their home, there might be a nest somewhere either on or inside your roof or chimney. Removing it is fairly straightforward, just watch out for eggs or small birds.

One removal method we don’t recommend is poison. The reason being is that often the pest will crawl into an area of your home that may be unreachable for you or an exterminator. If this is the case then the dead carcass can really stink up your home and even lead to the growth up other unwanted pests.

Best Methods For Preventing Pests From Coming Back

So let’s say you finally get the pests to leave, but how do you stop them from returning? This step is just as important as getting rid of them. It’s beneficial to take some time to work with a local pest patrol agent to determine a plan of action. In order to prevent pests from returning, here are some of the most effective methods to try.

Seal it Tight:

When you’ve identified the source or the entry spot, seal it tight with non-chewable material so the pests can’t use it again. Pests cannot get into your home if it’s properly sealed. Sometimes roof shingles or flashing will come loose, giving critters a way to tunnel in. If you have missing shingles or roofing tiles, they need to be replaced as soon as possible and the underlying layers should also be checked for damage.

Clean Your Gutters:

When gutters aren’t cleaned regularly, they can become a home for all kinds of creatures. You can get bugs, squirrels, rats, and even birds’ nests in them. In addition, because backed-up gutters are also a common cause of leaky roofs, you’ll definitely want to make sure they are kept clear.

Trim Back Foliage:

Tree branches that touch or overhang your roof could act as a bridge for all kinds of pests. To keep your roof protected, trim back any foliage that touches your home. This will make it harder for pests to gain access. You should put at least several inches between your house and any tall bushes or trees.

Protect Your Roof With Nets:

While this may seem unconventional, your local home and garden supply store usually sells netting you can use to stop pests from getting too comfortable. You can lay this netting over your roof and this will prevent pests from access. The netting does not harm the pests and it’s not intended to catch or tangle the pest.

Conclusion

Now I hope you understand How To Protect Your Roof From Pests. You can keep your home free of unwanted guests by regularly inspecting your roof or having a roofing professional do it for you. During one of the inspections, it’s important that you don’t procrastinate and let the pest reek havoc, otherwise, you’ll end up with a bigger problem down the line. However, before you take action, do your research and see what the habits are for your particular pest as each can vary and will likely dictate how to get rid of it.

Why you should clean and inspect your roof this spring

by Roof Repair

Why you should clean and inspect your roof this spring

Springtime is right around the corner which means it’s almost time to inspect your roof. With the changing of seasons, it’s always a good idea to create a checklist and spend some time ensuring your roof is working properly. Doing this will help protect you against a costly and unexpected repair down the road. We know that living through Canada winters can sometimes be challenging for people and the same goes for our roofs! With the combination of mother nature’s extreme weather conditions and forgetting to clean and inspect your roof, there will come a time when your roof fails. Harsh conditions our homes face include heavy rain, strong winds, large snowfalls and more. To help protect against a costly and unexpected repair, we’ve compiled a list of simple cleaning steps and things to look out for once springtime arrives.

Remove debris safely

Once the colder months have passed and the snow has melted, there is a very likely chance your gutters will be full of wet leaves and twigs. This is especially true if your home is situated near lots of trees and foliage. Doing this is a very easy job but it can take a bit of time depending on the amount of debris stuck in your gutters. Many people will wear gloves and physically pick up the debris and throw it out of the gutters. Because you’ll be on a ladder, you can get someone to help you collect the debris into a garbage bag as you remove it.

Deciding not to do this each springtime could mean your gutters become filled with mold which is an open invitation to pests and rodents looking for new homes. Not maintaining your gutters will also increase the chances of roof damage such as water leaks, raised shingles, and could risk the integrity of your home’s soffits, fascias, flashing, siding and overall roof functionality.

Clean your roof

While washing out your gutters, you’ll want to also clean off your roof itself. Removing debris then using a basic hose and/or leaf blower to wash off any dust and dirt will suffice. Sometimes people make the mistake of using a pressure washer to clean their roofs but this can be detrimental because it uses too much pressure and doing so may damage your shingles. And never forget to always get someone to help you with cleaning your roof because doing it alone is a safety hazard.

Don’t forget your downspout

Lastly, you should also clean out your downspout once the gutters are complete. You can do so by removing the horizontal pipes (if your downspouts have these), taking your garden hose and feeding water through the top where the gutter meets the downspout. You’ll know you’ve cleared the debris once the water flows easily through the downspout and onto the ground.

Look for early warning signs of damage

Once your roof, gutters and downspouts are all clean, it’s time to look for any damage that may have occurred over the winter. While looking for signs of damage on your roof it’s a good idea to record anything you find on a document so you can provide the information to a roofing professional if you decide to seek one.

Shingles, dark spots, flashing

Firstly, you’ll want to scan your roof for any raised, missing or damaged shingles. Shingles can become worn overtime as they face different weather conditions. Then you will want to examine your roof for any dark greenish spots as this is an indication of mold and/or water damage. Looking for these spots is especially important if your roof is beneath plenty of trees! Next, you’ll want to check your roof’s flashing to ensure it has not become loose. This is common in areas surrounding chimneys, edges and even skylights.

Check the inside of your home

Routine roof examinations shouldn’t end while you’re outside because checking the interior of your roof is just as important! If you discovered a missing shingle or crack in flashing, it could mean the problem has traveled into your home. Finding a leak early could be the difference between a minor repair and a costly and harmful problem such as mold and mildew. Using a basic flashlight, take a moment to inspect your attic for any signs of water, rotting, smells, rodent poop, ect.

Know when to call a professional

We are the experts at Cambie Roofing and we pride ourselves in the fact that we offer free estimates to potential customers. So, if you’ve performed your routine springtime roof check and you’ve discovered the need for a repair, don’t hesitate to call us! No matter what the problem is, big or small, old roof or new roof, we will be happy to help. Tackling a problem sooner than later will help protect you against an even more expensive bill. And even if you don’t think there’s a problem with your roof, you can give us a call if you’d like us to perform your springtime inspection. Some people are not comfortable or physically capable of using a ladder to check their roofs but that is where we come in handy! Our trained professionals can assist you with any roofing needs and/or questions. Getting someone to inspect your roof twice a year is best, especially in the springtime.

5 signs your roof needs repairing or replacement

Oftentimes we forget just how important the roof is over our heads. But just like everything else on the inside and outside of our homes, our roofs will eventually need repaired and/or replaced. Knowing the early signs of roof damage can save you thousands of dollars in the long run and it could mean the difference between a small repair and a total replacement. Getting into the habit of routinely checking your roof on the outside and inside is a good starting point. You’ll want to familiarize yourself with the early signs of damage so you’re prepared when and if something happens. To help, we’ve compiled a list of eight signs your roof may need repaired or replaced.

Cracked or curled shingles

Knowing what it looks like when your roof’s shingles are damaged is essential when questioning if your roof needs replaced. Asphalt shingles are the most common and they usually only last up to 20 years before needing replaced, but this isn’t a guarantee. If you live in an area with lots of rain, scorching temperatures, wind storms, heavy snowfalls and/or humid conditions, remember that your roof is always exposed to whatever mother nature brings its way. A shingle can become cracked or curled for a variety of reasons such as improper installation, extreme weather conditions or if it has surpassed its lifespan. A cracked or curled shingle is a sign that your roof needs some work. These damaged shingles are no longer laying flat against your roof which could lead to a variety of problems such as water exposure or an invitation to unwanted rodent visitors.

Moss

If you’ve noticed something green growing on your roof, be alarmed! Moss is a sign that your roof needs attention. Moss thrives in damp environments so if your roof is in a shaded area near trees and other vegetation and the climate is relatively moderate, your roof is constantly exposed to moisture. When moss spores are carried through the wind onto your roof, they will plant themselves between your shingles and will start to grow. Feeding off of rain, moss will become thick and spongy and will start to take over your shingles. This will cause the shingles to lift, inviting water into your roof. Moss that is left on a roof for a long period of time will not only decay your roof, but it can also lead to harmful mold. Depending on the amount of moss you find on your roof, contact a professional to assess the situation.

Shingle granules are deteriorating

Similar to when shingles curl and crack, if you notice the granules on your shingles are missing, this is a sign they are no longer effective in protecting your home. A good way to determine if your shingles are losing granules is to check your roof’s gutter and downspouts. Granules are tiny bits of rock which are attached to shingles to protect them from the elements. Over time it is normal for them to erode and fall off but how long it takes to do this depends on the quality of your shingles. If granule loss is noticeable, it’s time to reach out to a roofing company and get an evaluation.
Leaks
One of the most common and dreaded signs your roof needs some fixing is when it’s leaking. Whether its missing shingles, flashing problems or a clogged gutter, a roof leak can happen in many ways, causing lots of damage to your beloved home. Sometimes it can be very difficult to pinpoint where a leak is coming from. Be sure to check your attic regularly and inspect the outside of your roof. While there are many DIY fixes for roof leaks, getting a professional to examine the damage is always a smart choice.
Old age is creeping up
Just like anything in your home, your roof can become outdated and with that, it can bring serious problems. To prepare yourself, always keep a paper trail from the last time your roof was installed, replaced and/or serviced. Each style of roofing differs along with its quality and recommended lifespan. Knowing when your roof is due for an inspection can eliminate all problems associated with an aging roof. Preparing yourself for when the time comes to replace your roof will help alleviate any financial surprises.

Conclusion

If you’ve noticed a few problems with your roof, don’t jump to conclusions! A few cracked shingles doesn’t mean you need to spend thousands of dollars replacing your entire roof. A little bit of routine maintenance and double checking goes a long way when it comes to your home’s roof.

Blistering and alligatoring, DIY vs Qualified Roofer in Vancouver

What’s The Difference Between Blistering and Alligatoring?

What’s The Difference Between Blistering and Alligatoring?

Blistering and alligatoring are two common problems with most membrane roofing systems. Alligatoring is a cracking pattern in the roof’s surfacing that looks a lot like alligator skin.
That’s the reason we them alligatoring. Blistering is a slightly different phenomenon in which bubbles form underneath the roof’s membrane.
Blistering sometimes results in cracks or pops, but unlike alligatoring, the damage caused by blisters usually follows the length of the blister rather than forming a pattern.

Commercial roofs, in particular, require different repair and maintenance routines than residential roofs.
For starters, most commercial roofs are usually flat and this means they react much differently to sun, rain, ice, and snow which means alligatoring and blistering are much more common. Commercial roofs often require more frequent maintenance to ensure there isn’t any damage and if there is wear and tear, it is taken care of before it can spread.

What Causes Alligatoring?

Alligatoring is a sign that your roof is aging. Prolonged exposure to the elements damage the roof’s surface, and after about five years, the coating may develop small cracks. If left untended, the problem will get worse and spread across your roof.
Fluctuation in temperatures, ice, snow and sunlight shifts will cause new cracks to appear while widening the existing cracks.
Because these problems are common among some membrane roofing systems, you should make sure to get a roofing contractor to inspect your roof at least twice per year.

Is it possible to Fix Alligatoring?

Roof alligatoring is a sign that your roof is aging but it is possible to prevent alligatoring, and to repair small patches before they get so bad that you have to replace your roof entirely. First, a roofing contractor will need to apply a new coating to the roof. He will start by cleaning the roof thoroughly, making sure that all dust and loose particles are removed. After that, the contractor will apply a primer that is compatible with the roof’s original surface, and once dry, apply the coating itself. Embed strips of fiberglass mesh in the coating as you apply it to help increase its strength.

What Causes Blistering?

Blisters form when there are pockets of air or moisture trapped between layers of your roof’s membrane.
If left untreated, a blister can grow larger and allow more moisture to get in so that the problem gets worse until more extensive repairs and possible replacement is necessary…unless it pops! The origins of blistering are several. Among them, we count poor ventilation, trapped moisture or UV light.
As these pockets expand and stretch the membrane they form bubbles. In severe cases, the membrane will actually crack when the pressure becomes too great. Once blistering forms, the membrane stretches permanently, which allows for even more air or moisture to infiltrate the membrane layers.
This causes even more expansion. Each time the sun heats your roof, there is the potential for the blisters to grow a little larger.

How to Fix Blistering?

In general, blisters keep air in will keeping water, preventing serious water damage. This usually means unless the blisters have certain characteristics, it may be preferable to leave them undisturbed. Some of the blisters may pop, but most of them may not.
The question is, should we repair all of the blisters or only the blisters that have exposed?  There are certain circumstances in which you should repair the blister:

  • The paint or surface is coming off of the blistered area.
  • The membrane itself has cracked.
  • The blister is close to a seam and may cause the seam to open up.

To repair a blister

To repair a blister, cut away the membrane until you reach an area where the membrane still adheres to the roof tightly. You’ll then need to reapply new membrane material at least as many layers as you removed over the blistered area.
Make sure that the new membrane extends at least six inches around the edges of the blister to ensure that your patch remains leak-proof despite the expansion and contraction caused by temperature shifts. Alternatively, on a bitumen roof, our roofing contractor may be able to cut an “X” into the blister and then peel back the loose membrane layers. He will then fill the void underneath the membrane with bitumen and then press the membrane back into place. Keep in mind that this type of repair is only advisable if the membrane is otherwise undamaged and the blistering isn’t too great.

Prevention of Alligatoring and Blistering

It is possible to prevent roof alligatoring and blistering by scheduling regular inspections and keeping up on maintenance.
Regular inspections will help ensure you’re able to tackle any blistering or alligatoring problems before they become bigger problems.
Our roofing contractors can apply a protectant or reflective roof coating on a consistent schedule to prevent alligatoring and other damage from happening. While prevention represent an additional cost, it will save you money in the long run: Alligatoring and blistering are expensive to fix.
As noted, flat commercial roofs require a bit more upkeep than sloped, residential roofs, and it’s important to have them inspected at least twice a year if you want to extend the life of your roof.

Repair

If you’ve noticed small splits and cracks in your roof, it’s best to call a roofing inspector. They will likely tell you if the problem is worth fixing or if it can be left to be fixed at a later date. At Cambie Roofing, we give you a realistic picture of what needs to be done to your roof.
Some small hairline cracks can be filled by applying an appropriately rated energy sealing polyurethane, but in general, it’s best to just get rid of those troublesome sections as they appear.
Most roofs come with warranties lasting on average between 10 to 20 years and so if your roof is starting to show signs of damage, it may be covered under warranty. Property owners and homeowners looking for roof replacement or roof repairs can call Cambie Roofing for a free roof estimate.

The Best Roofing Options for living in Vancouver

Looking for roofing options when replacing your home’s roof is an important decision, and can be an expensive process. That is why choosing the right roofing options and materials can improve your home’s aesthetic appeal.
But also, you need to think about increasing longevity and keep within your budget. Replacing the roof also increases the value of your home for resale.

Many homeowners underestimate the importance of a good roof. If you’re thinking about reconstruction keep in mind the premise:

There is no point in creating an amazing home if water is going to leak in and damage the inside. So, if you are rebuilding your roof, consider rain, snow, wind, and everything that can ruin it in a matter of hours – if not minutes.
It’s much better to have peace of mind and do it right the first time so you don’t have to worry.
As you probably know already, Vancouver is prone to a unique set of roof problems. Moss buildup, mildew and mold count among them due to the heavy amounts of rain the area gets.

The more you invest in your house, the better you’ll want to protect it

It is important that homeowners understand which type of roof can naturally resist these problems in order to efficiently protect the integrity of the roof and the inside of the home. Roofing materials are extremely important, but the actual style of the roof can play a major role when it comes to resisting a wet climate.

How To Choose Your Roofing Materials

There are so many different roofing options. You should ask your roofing contractor what is the best material for your home. If you’re not an expert, it can be very difficult to identify just the right material if you don’t know what it needs to be capable of surviving.
You should look for information about lifespan, weight so it won’t crush the roof framing, and roof sloping. You should also find out whether it’s permitted by local building codes, how resistant it is to fire and extreme wind, and how much it costs.
There are a lot of different types of roofing used in Vancouver, depending on style – asphalt composition shingles, metal, wood, plastic polymer, clay tile, concrete tile, and slate. We’ll go over some of the most basic options so when you talk to your contractor, you’ll be able to make an informed decision.

Asphalt Shingles

Asphalt Shingles are the most common and economical roofing material used throughout Metro Vancouver. They come in 2 main types; three-tab and architectural shingles. Both perform well with little e to no maintenance and come with varied warranties.
Three-tab shingles most often carry warranties from 20-30 years, while architectural shingles often have longer, and even lifetime, warranties.
On the other hand, asphalt shingles are effective and inexpensive. However, they are the last option to take into account because they do not enhance the visual appeal of homes, neither increase the value of your home.
Architectural shingles, however, come in many different styles and can mimic the look of more expensive roofing materials.

Cedar Roofing

Cedar roofs are a traditional Vancouver and Pacific Northwest roofing material that can give your home a natural, homely feel.
In BC, Cedar is readily available and fairly inexpensive. Cedar shakes and shingles are the most common wood roofing material and add a rustic, natural, particularly Vancouver appeal to many homes.
Due to the visually appealing nature of cedar products, using a cedar system can often increase the value of your home. While cedar products are lightweight and durable, they can be susceptible to moisture-induced mold or algae and may require more maintenance than other roofing options.
While untreated cedar roofing materials can fall victim to the elements, pre-treated options are now available. These pre-treated cedar shakes and shingles are slightly more expensive but offer a natural appearance and the equivalent effectiveness of a synthetic product.

Metal Roofing

Metal Roofing materials come in a range of styles, are durable, low-maintenance and visually appealing, with a clean look. The most common metal roofing material is standing seam, a series of interlocking panels that extend the entire length of the roof.
While installation of a metal roof is slightly more expensive than other options, it has a long lifespan, requires little to no maintenance and can increase the value of your property. Like asphalt, metal roofing materials that mimic the look of other roofing systems are available in many different styles.

Torch-on SBS Membrane Roofing

Torch-on SBS Membrane is available in many colours. It is one of the most durable roofing materials and can provide many decades of protection from the extreme Vancouver weather with proper slope and installation.
Torch-on membranes are commonly used in low slope or flat commercial and residential applications, giving them a more modern feel.
As these types of membrane systems are so robust they can greatly increase the value of your commercial or residential property. Torch-on is one of the more expensive options in roofing but the lifespan of the system can often offset the initial cost.

Don’t Forget about the Warranty

There’s a manufacturer’s warranty that covers all the problems that can arise from the actual roofing material.
Also, look for optional roofing contractor’s warranty that covers all the problems created by the contractors’ negligence. Accidents must be part of them when installing the roof.
Some warranties can’t be transferred to other owners. So, your children or a person to whom you sell the house must know and take previsions. Always search the contract for this information.
Homeowners must consider many factors when choosing the roofing material that best suits their home. Yes, aesthetic appeal and expense are important when choosing the roofing system. But homeowners should ultimately seek to find a balance between form and function.

Conclusion

It is important to understand which materials are the best for Vancouver’s weather conditions. Since British Columbia is a temperate rainforest, you need a roof that provides protection from the rain, wind, and the occasional snowfall.
If you have any questions or need an estimate on your roof call the experts. At Cambie Roofing, we have been in business for over half a century. Share the same confidence we have when saying we are your best roofing choice.
