How to Prevent Ice Dams and Damage

Vancouver has some of the trickiest winters since we experience rapid changes in temperature. Which can cause some trouble with our homes, especially with the roofs over our heads. When the temperatures dip below freezing and ice and snow build up on your roof, it cause plenty of damage. Which will be expensive to fix. Let’s see below How To Prevent Ice Dams and Damage.

During prolonged cold spells where snow and ice are allowed to accumulate on your roof. It can quickly build up into increasingly large blocks of ice or what are called ice dams. An ice dam not only weighs down your roof but stops water from running into your gutters and away from your home. This will cause the water to pool on your roof, causing water damage and leaks to your home’s interior walls and insulation. If left untreated, mold will form which will most likely mean you’ll have to replace your roof. Here are some tips to help prevent ice and snow buildup from causing major problems.

Prevent Ice Dams and Snow Build Up

Roofs are of course built to withstand a certain amount of weight. But if snow builds up and becomes too heavy your roof can collapse. Although this isn’t common in Vancouver, we do have bad snow storms every couple of years. If this is the case, you need to keep an eye on your roof and clear it once the storm has passed. A good general rule is that you never want more than a foot of snow on your roof at any one time. You can clear snow yourself with a rake or a shovel or call us at Cambie Roofing and we can take care of it for you.

Clear the Gutters

If Vancouver has a prolonged cold spell, it is common for ice to build up in your gutters and freeze them. If the ice builds up too much, the gutters can expand and cause them to shatter. Another common issue is that the ice becomes too heavy and can rip the gutters away, causing extensive damage to your home. You can chip the ice from gutters, but that can be extremely dangerous and you can damage your gutters. A better solution is to give us a call at at Cambie Roofing we can ensure the gutters are cleared properly so you don’t have to risk doing it yourself.

Keep the Attic Cold

As you know, heat rises in your house and gets trapped in the attic. Poor attic insulation and ventilation causes hot air to escape in the wrong places and rapidly heat the roof which melts the snow too quickly. These causes water to flow until it hits a cooler section of the roof. Usually toward the overhangs that aren’t in contact with the attic’s warm air and leads to ice build up and ice damns.

You should ensure you seal any gaps in your attic floor to stop warm air from seeping in. And make sure your attic is adequately insulated. Before the cold sets in, check the events to make sure they aren’t being blocked. While it might seem strange to add insulation for warmth but it allows cold air to come in through the vents, giving your attic some much needed air flow. The insulation also prevents moisture from building up in the attic. And keep the roof cool enough to prevent ice dams.

Insulation Issues

Insulation is a barrier of material within your roof space. It can either be laid between the horizontal beams along the floor of your attic or the rafters as a way to keep heat in your home. Check the insulation to see if it needs to be repaired. Although insulation lasts a long time, it does degrade and will eventually need to be replaced.  If heat is escaping through holes or areas that aren’t insulated then it can lead to uneven water pooling and trapped moisture. One thing to look out for is dark streaks in your attic or ceiling. If you see these dark streaks it means that water has seeped through and you should call a roofer immediately to get your roof repaired.

What To Do In Spring

Once the snow melts and winter has passed, you should inspect your property for signs of poor ventilation.  If you can catch these problem before they cause damage to your home. You will be able to save yourself some money and much needed headache.

You should always be vigilant and do your own inspections every couple of months. Simply walking on your roof with a good pair of binoculars can help you spot any trouble signs. However, your own inspections aren’t substitutions for a professional. You should always get a certified roofing contractor to do an inspection every six months. Because they will see something or notice a small detail that you can easily overlook.

The Solution

Those glistening icicles hanging from your roof may look beautiful. But, they can also be a telling sign that something isn’t draining the proper way. Icicles can be a telltale sign that water or snow are forming on your roof. That preventing melting snow from escaping through the gutters. Spending the time and money preventing ice dams is much more economical than having to deal with the potential fall out of ice dams.

If you are worried about potential ice dams developing on your roof, call Cambie Roofing to perform an inspection. Our expert roofers can quickly diagnose any problems with your roofing system. And perform maintenance to save you the trouble of dealing with ice and water damage. That possibly preventing you from having to replace the entire roof all together.

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.

Preventative Maintenance 101

by Roof RepairRoofing Services

Preventative Maintenance 101

A well-maintained roof is the first line of defence for any home or business, protecting against the elements and ensuring structural integrity. Preventative maintenance plays a pivotal role in extending the lifespan of your roof, whether it’s brand new or has weathered the elements for years. In this comprehensive Preventative Maintenance 101 guide, we will explore the essential steps to maintain both new and old roofs, highlight common issues to look out for, and discuss when it’s time to call the professionals at Cambie Roofing for expert assistance.

Maintaining New Roofs:

Regular Inspections:

New roofs benefit greatly from regular inspections. Conduct a visual check to ensure there are no visible signs of damage, such as missing or damaged shingles. Early detection allows for prompt repairs, preventing issues from escalating.

Clearing Debris:

Keep the roof free of debris like leaves, branches, and dirt. Accumulated debris can lead to water pooling, which can compromise the structural integrity of the roof over time.

Gutter Maintenance:

Clean and inspect gutters regularly. Proper drainage is essential for preventing water damage. Ensure that gutters are free from debris and securely attached to the roof.

Trimming Overhanging Branches:

Trim branches that hang over the roof. Falling branches can cause damage, and overhanging branches provide easy access for pests like squirrels to access the roof.

Maintaining Old Roofs:

Thorough Inspections:

Regular and thorough inspections are even more crucial for older roofs. Look for signs of wear and tear, such as cracked or curling shingles, sagging areas, or water stains on the ceiling.

Sealing and Coating:

Consider applying a protective sealant or coating to extend the life of an old roof. This can provide an additional layer of protection against the elements.

Addressing Leaks Promptly:

If you notice any signs of leaks or water damage inside your home, address them promptly. Water infiltration can lead to serious issues, including mold growth and structural damage.

Replacing Damaged Shingles:

Replace any damaged or missing shingles immediately. Damaged shingles compromise the integrity of the roof and can lead to more extensive issues if not addressed promptly.

Common Roofing Issues to Look Out For:

Leakage:

Leaks are a common issue and can result from various factors, including damaged flashing, missing shingles, or worn-out sealant around roof penetrations. Regular inspections can help identify and address leaks before they cause significant damage.

Mold and Mildew:

The presence of mold and mildew can indicate moisture-related issues. Proper ventilation and addressing leaks promptly can help prevent the growth of mold and protect indoor air quality.

Poor Drainage:

Inadequate drainage can lead to water pooling on the roof, increasing the risk of leaks and water damage. Ensure that gutters are functioning correctly, and downspouts direct water away from the foundation.

Wind and Storm Damage:

High winds and storms can cause significant damage to roofs, including lifting or tearing off shingles. After severe weather events, conduct a thorough inspection to assess any potential damage.

When to Call the Professionals at Cambie Roofing:

Extensive Damage:

If you notice extensive damage to your roof, including large areas of missing or damaged shingles, it’s time to call in the professionals. Attempting to repair significant damage without the necessary expertise can lead to further issues.

Persistent Leaks:

Persistent leaks that are challenging to locate or fix may require the expertise of roofing professionals. They have the tools and knowledge to identify and address complex leaks efficiently.

Aging Roof:

If your roof is reaching the end of its expected lifespan, it’s advisable to consult with professionals. They can assess the overall condition of the roof and recommend whether repairs or a replacement is the best course of action.

Professional Inspections:

Regular professional inspections, ideally performed annually, can identify potential issues before they escalate. Professionals at Cambie Roofing can provide a comprehensive assessment of your roof’s health and recommend preventative measures.

Conclusion:

Preventative maintenance is the key to ensuring the longevity and effectiveness of your roof, whether it’s a new installation or has stood the test of time. Regular inspections, addressing issues promptly, and enlisting the help of professionals like Cambie Roofing when needed are essential steps in maintaining a durable and resilient roof. By following these Preventative Maintenance 101 guidelines, you can protect your investment, enhance the overall safety of your property, and enjoy the peace of mind that comes with a well-maintained roof. Cambie will be going in depth about preventative maintenance in upcoming articles because we want our readers to understand how important it is to properly maintain their roofs.

Best Metal Roofing For Residential Areas

by with One Comment Roof SystemsRoof TypesRoofing Services

Best Metal Roofing for Residential Areas

Even in a city like Vancouver, the popularity of metal roof products has increased dramatically over the past decade, a clear sign that homeowners and builders are growing more and more aware of the benefits of this roofing. In fact, during the last ten years, a whole new type of metal roof materials has hit the market. These are a far cry from the old, expensive metal roofs which used to be on the market. Today’s metal roofs serve as high-tech answers to the need for durable, fire-resistant, lightweight roofing that looks at home on a house – and are cost effective too!

When considering a metal roof, you’ll first want to determine the fundamental look you want it to have. Residential metal roofing comes in two basic forms that are very different in appearance: sheet-like panels and shingles. Within these two categories, there are many variations, colours, and patterns.

Benefits of Metal Roofing Systems

The primary benefit of metal roofing is longevity. Manufacturers routinely offer 50-year warranties and even lifetime, non-prorated warranties. They claim their products will last two to four times longer than roofs with asphalt shingles. By avoiding one or two re-roofing jobs during the life of the metal roof, you will more than offset the higher initial cost.

There are other advantages, as well. Metal roofs are lightweight, sometimes allowing them to be installed directly over old roofs. Additionally, metal roofs are effective in preventing the spread of fire when hot embers fall on them. This could mean the difference of saving some of your most precious photographs or losing them in the event of a house fire. In fact, some insurance companies will give you a discount if you have a metal roof. In addition, metal roofing is made with a large percentage of recycled metal—often 95 percent—and when its useful life is done, it can be recycled again. No worries about it filling up dwindling space in landfills.

Metal Roof Materials

Residential metal roofing is generally made of steel, aluminum, or copper. Rolls of 24- or 26-gauge steel sheets are given a metallic coating to prevent rust, followed by a baked-on paint finish. Aluminum sheets don’t require the metallic coating but do get painted. Copper, often called a natural metal product, is neither coated nor painted, because it weathers without corroding. It is sometimes used for special features, such as the roof of a prominent bay window.

Metal Roof Textures and Finishes

Metal roofing products can be stamped into many shapes and are typically installed as interlocking panels with hidden fasteners. Viewed from a distance, they offer fairly convincing renditions of shingles and tiles.
Standing-seam metal roofs look exactly like what they are–long sheets of painted steel with vertical seams. From a design perspective, they are a purer product but not suitable for every home. Standing-seam roofs are perhaps best matched to the simple lines of cabins and contemporary home designs.

Myths About Metal Roofs

Myths and legends get started about all sorts of people, places, and building material. Metal roofing has more than its share, perhaps because it has undergone so many transformations over the years. Here are the most common myths about metal roofing:
• It will increase the likelihood of a lightening strike. Metal conducts electricity, but electricity is not drawn to it so you don’t need to worry about stormy weather.
• Metal roofs are noisy in the rain. Not so. They may even be quieter than other roof types
• A metal roof will make your house colder in winter. Actually, a metal roof has no effect on the temperature of the typical vented attic in winter. It’s the insulation under the floor of your attic that keeps you warm.
• Metal roofs are susceptible to damage by hail. While extremely large hailstones can dent a metal roof, normal hailstorms will not. With textured roofs, minor denting is not readily visible.
• You cannot walk on a metal roof. You can, but you have to know how to do it without causing damage. Check with the manufacturer of the product you choose.

Metal Panel Roofing

The most familiar pattern of panel-style metal roofing, “standing-seam roofing,” has raised ribs every 6inches or foot and is applied vertically on a roof and doesn’t attempt to look like anything other than what it is. It has a decidedly commercial look that is favoured by architects for its honest, clean, contemporary look, It is commonly used on homes ranging from mountain cabins to modern masterpieces but would look very out-of-place on a Colonial home.

Metal Shingle Roofing

Metal shingle-style roofing is quite different than sheet roofing. With this style, metal is formed into shapes that imitate Spanish tile, wood shakes, or slate. In addition, these shingles are typically given multiple-layer factory finishes that may include granulated-stone topcoats to complete the realistic effect.

Conclusion

Because a new roof is a major investment and something you’re likely to live with for a long time, it’s important to choose your roofing contractor carefully. This holds true for all types of roofing contractors but is even more important with metal roofing contractors because application of a metal roof is a specialty that requires skills and tools that are quite different than those used for installing more-typical roofing products. Whereas a typical roofing contractor can install wood or asphalt shingles, it takes a specialist to install mot types of metal roofing. At Cambie Roofing, we are experienced with all types of metal roofs and give you a fair quote.
For sheet metal roofing systems, choose a contractor who has had at least three years of experience installing metal roofs.

The best way to find a good metal roofing contractor is through friends and neighbors who have had similar work done. At Cambie Roofing we have an excellent reputation. Just look at our testimonies or ask any of our customers. If you ask, we’re happy to refer us to some of our happy clients.
Make appointments with at least three professional roofers. Make sure they are well experienced at the type of roof you intend to have installed. After talking to a couple of contractors, we know you’ll be happy to come back to us.

ways winter impacts your roof

Ways winter impacts your roof

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.

Types on metal roofing systems

Metal systems covers a wide variety of roofing systems and can mean many different styles and materials. Steel, stainless steel, aluminum, copper, and zinc alloys are all materials used for metal roofing. Each has different properties that affect durability, price, and appearance.

What Types of Metal Roofs are out there?

Before making a decision on what type of metal roof you want, you need to know what types of are available. There are different types that impact price and performance that you should be aware of. It is important that this knowledge weighs in on your decision. You don’t want to make a decision to repair your existing metal roof, only to find out later that you have a metal roof that is a poor insulator and it would be worth your money to upgrade.

Conventional Metal Roofing Materials

By far, the most common materials used for metal roofs are steel and aluminum which can be used for a variety of different roofing systems. Steel, used for most metal roofing, is heavier and sturdier than aluminum. Manufacturers have settled on a number of durable coatings and finishes that protect steel from rust and corrosion. Steel is usually zinc-coated for corrosion protection and then sealed. A coating of primer offers adhesion and a baked-on acrylic top coating adds colour and protection. Because sheet systems are designed for commercial applications, they generally are given highly durable paint finishes.

Aluminum, extremely lightweight, is used for some residential metal roofing. It won’t rust, but it must be painted or coated for appearance. Coatings are similar to those used on steel. Aluminum is a very soft metal, so it dents and mars easily and isn’t nearly as rigid as steel. Aluminum-alloy coatings provide corrosion protection, but they react with alkaline chemicals in masonry mortar and cleaning solutions that might spill on the metal’s surface during construction.

Types of Metal Systems

Systems tend to fall into three distinct categories based on panel size and attachment method. Sheet metal shingles or tiles are stamped sheet metal with decorative finishes and textures. Commercially available tiles simulate clay tiles or cedar shingles, and they come in other decorative shapes. Metal tiles are very light and can be susceptible to high winds. You should be aware of wind ratings for your neighbourhood. Metal tiles might not be right for your building. Metal tiles also are susceptible to crushing if technicians or others walk on the surface.

Sheet metal panels. These panels also are hydrokinetic roofing systems and are most applicable for roofs with a steep slope. Panels are available in a variety of profiles, sizes and thicknesses. Heavier-gage metal panels are suitable for applications such as warehouses and attach directly to the structural framing. The economic advantage of direct-attachment systems is the metal panels provide the structural diaphragm, roof sheathing, and waterproofing.

Different Types of Metal Roofs

R-Panel

R-Panel metal roofs are the low-maintenance metal roofing option. Their easy installation cuts own on labor, time, and disposal costs, so costs for the entire project are kept low. These roofs are also available in many different colours that look very nice on a roof. These roofing systems are very popular for both residential and commercial roofing systems. Their ease of installation has helped to make them a very popular flat metal roofing option. As with all metal roofing systems, these systems are prone to rusting and should be frequently painted or coated to combat this problem.

Corrugated

This is the classic metal roof, common on many older barns and shacks; the “original” metal roof. Corrugated metal panels are now often galvanized and used on restaurants and retail establishments to create a classic feel. Corrugated metal roofs integrate well with fiberglass skylight panels because they typically have similar patterns and structural designs. Moreover, Corrugated metal roofs have been around for a long time and they have stood the test of time.

Architectural Standing Seam

This roofing system provides superior wind uplift protection and resistance to water than other metal roofing systems because of the way the panels interlock. They are extremely tightly constructed and provide a watertight seal that is superior to all other metal roofing systems. Many manufacturers apply a sealant to the panels in the factory, which works to maintain the structural integrity in thermal variations.

Modular Press

Modular Press panels are painted interlocking panels with standard dimensions and shapes and are growing in popularity for residential applications. They may be steel, aluminum, copper, zinc, or terne metal.
The roof panels are attached with hidden fasteners directly to the roof deck in most applications. They are usually 4-way interlocking to provide exceptional wind up-lift resistance.

High-End Metal Roofing Materials

Other forms of metal roofing are also available but can be very expensive. However, if you can afford them, they provide stunning roofs on luxury homes. Copper metal roofing, rooted in centuries of use, will not rust, has no “finish” to scratch or peel, is soft enough to easily tool, and weathers naturally to a beautiful verdigris patina. Unfortunately, it’s extremely expensive. Alloy roofing products are formulated for strength, graceful weathering, and durability. Cost depends on the specific material, but, as a group, they are pricey. Stainless-steel roofing, a very expensive roofing material, won’t rust or corrode. Terne coating can give it a natural matte-gray finish.

Maintenance

Lastly, we should look at how to maintain a metal roof so it lasts as long as the building. Roofers should walk directly over joists and purlins to prevent accidental bending or dishing of sheet metal roof panels. They also should minimize foot traffic on sheet metal roofs because scratches can expose the steel sheet, creating the potential for corrosion. Roofers and owners also should be careful not to scratch the surface when walking on or cleaning debris off a sheet metal roof. This will ensure you get the most out of your metal roof.

Conclusion

Metal roofing systems can be a cost-effective and viable choice for new and replacement roofing. Taking care in selection, design and installation will result in an attractive, low-maintenance solution. Call us at Cambie Roofing if you think about installing a metal roof or need an estimate.

Before embarking on your festive lighting project, prioritize safety. The safety of both yourself and those assisting you is paramount. Begin by ensuring that your ladder is in good condition and positioned on a stable surface. A wobbly or unstable ladder can lead to accidents. It’s advisable to use a buddy system, having someone else present during the installation process. This not only provides an extra pair of hands but also adds an additional layer of safety. If your roof is steep or particularly high, consider hiring a professional to handle the installation. They are equipped with the experience and tools necessary to navigate challenging roof structures safely.

Choose the Right Lights:

Opting for lights specifically designed for outdoor use is essential. Look for a label indicating that they are suitable for all-weather conditions. LED lights are a fantastic choice for outdoor decorations. Not only are they energy-efficient, reducing your electricity consumption, but they also emit less heat. This lower heat emission is beneficial in preventing any potential damage to your roof or other surfaces. Investing in high-quality, outdoor-rated lights ensures not only a stunning display but also the longevity of your decorations.

Inspect Your Roof:

Before attaching any lights, a thorough inspection of your roof is crucial. Identify any existing damage or vulnerabilities that might be exacerbated by the installation process. Addressing these issues beforehand ensures that your roof is in optimal condition to support the added weight of the lights. Clear debris such as leaves and branches to create a clean, safe surface for installation. By starting with a well-maintained roof, you contribute to the overall health and longevity of your roofing system.

Use Clips, Not Nails:

To avoid damaging your roof, opt for specially designed clips for light installation instead of nails or staples. These clips are designed to be roof-friendly, allowing for easy attachment and removal without causing harm to your roofing materials. Ensure the clips you use are suitable for the type of lights you’re installing. This small investment in the right accessories can prevent potential damage and make the removal process smoother.

Mind the Weight:

Be mindful of the weight of the lights and any additional decorations you plan to install. Excessive weight concentrated in one area can strain your roof structure. Distribute the lights evenly across your roof, considering the load-bearing capacity of different sections. This not only protects your roof from potential damage but also enhances the overall aesthetics of your display.

Secure Wiring Safely:

Keep wiring secure and away from walkways to prevent tripping hazards. Use insulated extension cords rated for outdoor use to ensure they can withstand varying weather conditions. When securing cords, avoid running them under heavy objects that could damage the wiring. Additionally, be cautious not to pinch cords in windows or doors, as this can lead to fraying or other damage.

Be Weather-Wise:

Choose installation days with favorable weather conditions. Attempting to install lights during adverse weather, such as rain or snow, can increase the risk of accidents and damage to your roof. If possible, plan your installation on a dry and mild day. Weather-appropriate installation not only ensures safety but also helps preserve the quality of your decorations, preventing potential issues caused by exposure to the elements.

Turn Off Lights When Not in Use:

To conserve energy and reduce the risk of overheating, turn off your Christmas lights when you’re not at home or when you go to bed. This simple measure not only saves electricity but also contributes to the longevity of your lights. Additionally, it reduces the strain on your roof by minimizing the time the lights are in use.

Conclusion:

By following these guidelines for safely installing Christmas lights on roofs, you can transform your home into a festive wonderland while safeguarding your roof from potential harm. Prioritizing safety, choosing the right materials, and taking preventative measures will ensure that your holiday light installation is not only visually stunning but also a stress-free and enjoyable experience. Embrace the spirit of the season, knowing that your efforts are enhancing the beauty of your home without compromising its structural integrity. Remember, a well-lit and secure holiday display brings joy without the worry of roof damage.

Shingle vs. membrane roofs

Shingle vs. membrane roofs

In today’s blog post, the experts at Cambie Roofing are diving into the differences between shingle and membrane roofs. Both systems play an integral role in the roofing industry and have been used for many years to safeguard homes or commercial buildings. When it comes to shingle vs. membrane roofs, here is what to know:

Shingle roof systems are often used in residential construction and are the most popular choice among homeowners. Membrane roofs are mostly applied to commercial buildings but have gained popularity among some residential builds as well. Today we are going to explore both systems, highlight their key differences and reveal whether or not they are a good option for your next project.

Shingle roofs

Shingle roofs are the most commonly used roofing system among homeowners in North America. This is because they are extremely affordable compared to many other roofing systems. Shingles are individual pieces that overlap one another to create a functional roofing system. There are various types of shingles available on the market, including the popular asphalt, as well as wood, metal and slate.

What type of shingle you go for will depend on your budget and your aesthetic preferences. Asphalt shingles have been around since the early 20th century and have since revolutionized the roofing industry as the most affordable option for homeowners. While affordable, shingle roofs do not have the longest lifespan and are prone to needing maintenance and/or replacement sooner than other types of roofing.

Membrane roofs

Looking at membrane roofs, these systems are the most popular among commercial roofing projects. Unlike shingles, a membrane roof consists of a single layer of material that is installed and welded together in large sheets to make one continuous layer of protection. Membrane roofing systems are often made from Ethylene Propylene Diene Monomer (EPDM), Polyvinyl Chloride (PVC) or Thermoplastic Olefin (TPO).

Predominantly used on commercial buildings, membrane roofs are a good choice if your roof is flat or has a slope of less than 14 degrees. Lots of commercial buildings have flat roofs compared to residential buildings which is why membrane roofs are not as common in the home roofing world. Membrane roofing systems are extremely durable and offer energy savings.

Key differences

There are many key differences between shingle and membrane roofs, aside from shingles being popular in sloped residential builds and membrane roofs being more popular in flat roof commercial builds.

Lifespan

Both shingles and membrane roofs require professionals to install them. However, when it comes to durability, shingles have a shorter lifespan. This means shingles don’t last as long as membrane roofs and require more maintenance including repairs and replacements. Typically a well-kept shingle roof can last up to 20 years and in some cases 30 years. However, membrane roofs have a way longer lifespan with averages ranging between 30 and 50 years.

Maintenance and durability

And if you live somewhere with extreme weather conditions including hail, strong winds and heavy rain, membrane roofs are very resistant. Shingle roof systems are more prone to damage from ice dams, especially if they are old. Membrane roofs typically don’t need as much upkeep either. So, if you’re looking for a long lasting roof with little maintenance, a membrane roof could be right for you as long as your roof is flat or extremely low sloped.

Cost differences

As already mentioned, the cheaper option when it comes to shingle vs. membrane roofs is shingles. They have a more affordable initial installation and the materials are also less expensive than membrane roofing materials. You will however likely be spending more money more frequently to upkeep and repair your shingles than you would with a membrane roofing system.

Environmental impacts

Shingle roofs can be found in a variety of different materials, including some that are more eco-friendly than others. Lots of the shingles on the market are made from recycled materials including rubber, plastics and wood fibers. Picking materials that have been recycled helps lower your carbon footprint. However, if you opt for the very popular asphalt shingle when choosing your roof, be aware that these are not eco-friendly. Experts suggest they can take up to 400 years to decompose.

Looking at membrane roofing systems, it also depends on what materials you choose when it comes to environmental impacts. TPO roofs can be recyclable however the production process involves many chemicals derived from fossil fuels. EPDM roofing is also recyclable and does not contain harmful plasticizers or chlorine, however it also uses fossil fuels when being produced. Lastly, PVC roofing has transformed in recent years to not include chlorine. There are far more environmentally friendly PVC roofing formulas on the market today but some membranes still use fossil fuels.

Energy efficiency

When it comes to shingles, they aren’t overly energy efficient. This is especially true if you have dark asphalt shingles, because they absorb lots of heat. So if you live in a place with warmer temperatures, your asphalt shingles could be causing your cooling costs to go up. Luckily, there are a few ways to make your shingle roof more energy efficient. This includes choosing a shingle that is light coloured such as white or light gray. These colours reflect heat and sunlight which means they will help keep the inside of your home cooler.

Another way to make an existing shingle roof more energy efficient is to add a cool roof coating. It is best to consult the professionals at Cambie Roofing before applying a cool roof coating. This will ensure the roof is in perfect condition and is clear of all debris. As for membrane roofs, they can be very energy efficient. This is thanks to the fact they reflect sunlight and in turn, lower your home’s heat absorption. Questions? Contact us today.

Roof Warranties

The Ins and Outs of 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.
