Understanding roofing terminology

Whether you’re a homeowner or business owner looking to improve, repair or replace your roof, it can easily get confusing when researching if you don’t understand roofing terminology. The experts at Cambie Roofing are here to help if you have any questions but we also understand the importance of educating people on these terms.

Doing so helps people make informed and confident decisions when it comes to their roofs because roofing is not a simple task! In this blog post, we will dive into all of the roofing terms that we think people should know about to help them understand roofing terminology.

Roofing components

1. Roof Pitch:

The roof pitch refers to the angle or slope of your roof. This is an essential component of your roof as it is responsible for how water and debris runs off of it. The steeper your pitch, the easier it will shed water and debris. A shallow pitch will require more waterproofing.

2. Gutters:

A gutter is a trough which is installed along the eaves. Its job is to direct rainwater away from your home by channeling it away from the foundation.

3. Eaves:

The eaves are what hang over the edges of your roof. They are important because they provide the house with shade as well as protect against water runoff. Typically the gutters are attached to the eaves to help direct rainwater.

4. Gables:

Two slopes that intersect create gables. These are triangular areas that compliment the look of your home but also support ventilation.

5. Rafters:

An easy way to understand what rafters are is thinking of them as your roof’s skeleton system. These are wooden beams that act as the framework for your roofing systems shape and support. They are installed diagonally from the top end of the walls all the way up to the top of the roof, also called the ridge.

6. Ridge:

This is the tallest point of the roof where the slopes meet. If your ridge is properly maintained, it will prevent moisture from entering your attic.

7. Fascia:

Your roof’s fascia is connected to the ends of the rafters. They are horizontal boards that support the lower edges of the eaves. The fascia can be made from different materials such as wood, vinyl, aluminum and more.

8. Soffit:

Located outside underneath the eaves, soffits allow air circulation throughout the attic in order to protect against moisture.

9. Decking:

Before building a roof, you must have decking which is the base layer of the entire structure. This is usually crafted using plywood.

10. Valley:

The valley is found inside where two slopes meet each other.
Underlayment: The underlayment is situated beneath the roof covering as an extra layer to protect against water. In case the top of your roof leaks, the underlayment is there to save the day. It is typically made from synthetic materials.

11. Downspout:

The downspout is a vertical pipe that connects to the gutter to bring the water from the gutter to the ground. In some cases, water runoff will be directed to a drainage system.

12. Chimney:

The chimney is a vertical structure that extends out of your roof. It normally houses a fireplace.

13. Skylight:

This is a window that is installed on the top of your roof. Many homeowners like these because they allow an abundance of natural light into the interior.

14. Flashing:

Flashing consists of thin metal pieces that are installed around roof openings, joints and places where materials intersect. Flashing is there to keep water out! It is highly important around things like chimneys and vents.

15. Shingles:

Shingles are the world’s most common roofing material. They come in many different types including asphalt, wood, slate and even metal. They are flat pieces that overlap each other to create your roof’s protective barrier. They are very cost-effective, making them the most popular choice among homeowners.

16. Tiles:

Another roofing material, tiles can be found in clay, concrete and even composites. They interlock to create an aesthetically pleasing and durable roofing system. Many homes that use tiles are Mediterranean-styled.

Roofing Professionals

When it comes to roofers, you might hear more than one term related to the professionals working on your home. If you’re unfamiliar with them, it can become a bit confusing. Not to worry! Here are the most common terms when it comes to roofing professionals:

1. Roofer

A roofer is responsible for the installation, maintenance, repair and replacing of roofs. They carry the proper qualifications, skills and knowledge to work on various roofing systems – both residential and commercial.

2. Contractor

A contractor is responsible for overseeing the projects from the beginning until the end. They are responsible for getting work permits for job sites, hiring other subcontractors and ensuring all safety standards are adhered to.

3. Architect

Architects are the designers behind it all. They play a very important role in achieving the desired aesthetics of the home while ensuring factors like the roof pitch and materials align with the look and functionality of the roofing system.

4. Inspector

Lastly, the roofing inspector is there to assess the overall condition of the roof while searching for any potential problems. They are there to find small issues that could grow into larger problems if left unaddressed.

To conclude

These are just a few of the most common roofing terms that are used in our industry. If you’re faced with an unexpected expense or issue, the last thing you want to worry about is understanding your potential roofing contractor when they’re explaining things to you. The experts at Cambie Roofing understand that the average person will not know all of these terms but we pride ourselves in excellent communication.

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 Commercial Roofing from Winter in Vancouver

by commercial roofing

Can you imagine working while being exposed to rain, snow, and high winds? Neither can we. Whether in Vancouver or in any other place in the world, that roof in the top of your commercial building assumes an irreplaceable role for you and your business. Do you know what to look for a commercial roofing company in Vancouver from Winter?
Your roof is a defence against the outdoor elements. It protects your business and the people who run it, making sure that you and everyone else is safe under it. In so doing, the roof takes everything that nature throws at it.
Most commercial property owners don’t pay enough attention to the roof until something inconvenient happens, say like a leak. Commercial roofing systems in Vancouver give in to extreme weather irrespective of the material and type.

Don’t wait for the brunt of winter to take its toll on your roof before you acknowledge the need to protect it!

The accumulation of snow and ice on top of your commercial building causes immense damage to the roof, starting with the small components and progressing to the whole structure. If you undermine the value of preventive measures, it might very well be the last winter for your roof.
Taking the appropriate measures to guard your commercial roof against winter isn’t merely about protecting the building; it allows you to be energy-efficient, too. Without protection, even a newly-installed roof won’t reach its expected lifespan.

The Dangers of Winter in Vancouver (and what to look for in a commercial roofing company)

It doesn’t matter if you’re situated in an area with severe or mild winter – protecting your roof is non-negotiable.
A winter protection program begins with the identification of minor issues that are likely to become a major headache once the cold season kicks in. Most of these issues point to the accumulation of snow and thermal movements.
Prepping your roof right before the arrival of winter makes sense since it’s easier to work on a dry roof and warm weather. If you choose not to fix those minor issues, you end up paying top dollar for an emergency commercial roof repair. The dangers that a commercial roof faces during winter include:

1 – Collapse

In Vancouver, snow is heavy. This means you don’t want it to collect on your roof. Winter months usually produce as much as six inches of heavy snow. It corresponds to about 40 pounds of weight that your roof must hold.
If the sun doesn’t come out the next morning, there’s not enough warm temperature to melt the buildup of snow on top of your commercial building. This weight puts a lot of strain, even on an expensive commercial roof.
There’s a chance that a solid roof collapses when the load-bearing components could no longer hold the excessive weight. We don’t need to talk about what happens when the roof collapses.

2 – Ice Dams and Leaks

Because of the extremely low temperatures in the winter, water that collects at the edges of the commercial roof freezes and builds an ice dam.
The ice dam prevents the melted snow from draining, which in turn causes water pooling—pools of water in one part of the roof cause unnecessary stress to the structure.
Over time, the damage increases and leaks begin to appear through the gaps found in between the structural components.

3 – Weakened Roof Due to Temperature Fluctuations

Sub-zero temperatures in the winter aren’t the only cause for concern when it comes to your commercial roof.
The frequent shift from extremely cold to warm temperature may cause contraction and expansion of the roofing material. Cold nights and sunny days put the roof at a compromising situation, weakening its structural integrity in the process.

Commercial Roofing in Vancouver: Ways to Protect your Business

Now that you have a much better understanding of your commercial roof’s susceptibility to the winter elements, it’s time to learn how to protect it.

Look for the Vulnerabilities

You don’t have to do this yourself. Call a trusted commercial roofing company in Vancouver to perform a complete inspection, and do this before winter comes. A professional roofer knows where to look for those areas which are susceptible to damage from snow and ice.
The list includes drainage sites, gutters, curbs, and the roofing membrane. Any sign of buckling and minor damage must be addressed since those components are likely to give in to the incoming season.

Cleaning your Commercial Roof in Vancouver

Your commercial roof is filled with debris without you knowing it. Don’t fall under the trap of combining snow with other unwanted stuff on top of your roof.
Aside from putting your gutters at risk of clogging, the presence of debris left by the summer and fall months puts the entire structure in danger of incurring heavy damage. Adding snow and ice to the debris leads to water overflow, leaks, and possible collapse.
Since you don’t want that to happen on your commercial building, then work on cleaning your roof right before the snow starts to fall.

What to Expect from Commercial Roofing Companies in Vancouver

Snow Removal Plans

If snowfall is guaranteed in your location every winter, it makes sense to devise a plan to remove the snow and ice on the roof. It’s not that difficult to get rid of the snow right before the freezing and thawing cycle.
The challenging part is coming up with an efficient way of doing it. The purpose of a snow removal plan is to help you act fast to prevent the buildup of ice on the roof. Once ice builds up, it becomes doubly challenging to remove it.

Coating System for Added Protection

Treat commercial roof protection as more of a necessity than an option. Embrace the reality that the freezing temperatures of winter alone puts the structure at significant risk of damage.
So, when snow and ice begin to pile up, you don’t want your roof to be devoid of any protection. Investing in an advanced coating system means you get an extra layer that prevents water penetration.
When the snow melts on your roof, water finds its way to existing gaps and flaws. The coating system prevents this from happening.
The best thing about protecting your commercial roof from the havoc of winter is that you don’t have to do anything other than hire a reputable roofing company. Be sure to choose someone who has legitimate experience in handling commercial roofs.

Roofing Quote: What a Homeowner Should Look for and Expect

by with No Comment Roof SystemsUncategorized

If a crack or a leak needs repair or maintenance, it can be easy to shove it into the background of your mind and not think about it. As an essential part of your house and your family’s protection, a roofing quote can be overwhelming and scary. You will probably have a lot of questions such as:

  • How much is it going to cost?
  • Does the entire roof need to be replaced?
  • How long will it take?

As you’re not a roofing expert, it can be scary to leave the decision to other people. The good news is at Cambie roofing, we have the experience and the knowledge to steer you in the right direction without being too salesy. Because ultimately we leave the decision up to you.
Many homeowners have horror stories about when a roofing contractor quotes them something and it costs way more than expected.  These experiences tend to have a lasting and negative effect and causes them to suspect all roofing contractors are lying to them. Thankfully this is not the case.

Roofing Quote: How A Roofing Contractor Quotes  

To start the roofing quote process, we recommend the homeowners get three or four quotes for comparison purposes.
Unfortunately, hidden costs are always a possibility when it comes to any roofing project, such as unseen rotten wood or stucco that needs to be removed and replaced. Always ask your roofer to go over any potential extra charges. That way, you won’t be hit with any significant surprises.
Remember that every roofing job is different and each coming with its own unique set of challenges.
While reliable roofers will do their best to give you the most accurate roofing quotes possible, sometimes the unforeseen does occur. If this happens an open dialogue between the homeowner and roofing contractor is always important.
Nobody likes it when cost overruns and while sometimes there are unavoidable, a lot of them can be prevented if you follow these three steps.

  1. looks at reviews on Better Business Bureau and Google
  2. interviews several different roofing contractors.
  3. takes the time to fully review and understand all aspects of the quote

There’s no getting around that roof repair or replacement requires a significant investment. However, you shouldn’t think of it as a cost, rather an investment into your home that will increase the value.
We get that you’re busy with your job and your family but it’s important that you don’t gloss over these steps or skip them entirely.  The consequences can be both stressful and costly.
This means you shouldn’t get a handyman or your cousin to do the work.  Rather make sure a certified roofing professional near you. This will make sure that no problems occur down the road which could easily have been dealt with by a professional.

What Questions Should Homeowners Have Answered?

What are the questions that should be answered, in a written quote, to help determine which contractor will be the best choice for the job?
Here is the information they want to see:

  • Complete contact information including company name, business license number, phone number, and e-mail
  • Anticipated duration of the project including estimated start date and completion date
  • Itemization of all materials (quantities, colours, brands, product codes)
  • Itemization of labour cost
  • Terms including the timing of all payments
  • Confirmation of valid workplace insurance and general liability insurance coverage
  • Details of all warranties relating to materials and labour plus conditions
  • Responsibilities for property clean-up

While this may be an extensive list, it is important for a  roofing contractor to provide this type of detail if they want to secure the roofing project, and it is equally important for the homeowner to be fully satisfied with this information before accepting and signing the agreement. There should be no surprises, for either party, when the work is done.
Here are some of the more important points broken down into greater detail.

Projected Time Frame

One of the important pieces of choosing a roofing company is getting an idea of the time frame for your roofing project. A professional roofer should be able to estimate when they will start, how long the project should take, and what date you can expect the work to finish. Having a clear timeline will help you figure out what will best suit your schedule and your needs.

Roofing Quote: A Complete Work Description

Roofing quotes should also include an itemized description of the work. That needs to be done including exactly what the problem was and how the contractor fixed it. Don’t settle for some vague description or no description at all. Make sure that you understand the entire process and what the roofing company is doing.

The Roofing Repair Cost

The cost is always one of the most important aspects of any roofing project. Therefore you’ll want to know what to budget for and prepare adequately. Your estimate should include the cost of both labour and materials including the roof covering, underlayment, flashing, and gutters. There should also be a separate breakdown of wish list items or add ons like removing your old roof, hauling away debris, or renting a dumpster.

The Bottom Line

Whether you are a new homeowner or have been living in your house for many years, undergoing a roofing project is never fun. Thankfully with a little research and some helpful advice can help to ensure the roofing work meets your expectations and your budget.
At Cambie Roofing, we have over 50 years of experience building and installing roofs. We will help you through every step of the process including the initial quote, pick the roofing that is right for your home, and the installation.

How to Prevent A Skylight Leak

How to Prevent A Skylight Leak

by with No Comment Roof Systems

Skylights are incredibly beautiful and can add some much-needed light to your home. Having additional natural light skylights can also look to expand interior spaces, reduce utility bills, and help make your home seem a little more inviting. The problem is, however, that skylights, especially when installed poorly, can be prone to developing water leaks. In fact, skylight leaks are among the most common roof repairs in residential homes. When a skylight starts to leak, it can be minor but can lead to expensive water damage, especially if it goes unchecked. A leaky skylight can also be an indication of other, more serious, hidden roof damage. You can contain and prevent skylight leaks by asking a roofing contractor to perform a regular roof inspection. Let’s find out below How to Prevent A Skylight Leak.

What Causes Skylights to Leak?

The first question to ask is what causes a skylight to leak. As with most things, it can be a variety of factors. Some people blame leaks on faulty product design but usually, it’s the skylight wasn’t installed or maintained properly. Sometimes it can be a combination of several factors including old age.

How To Spot a Leak

If you’re indoors, you might not even have to step outside to see if there is a leak around the skylight. If you see a dark spot around the skylight you need to distinguish whether it is a true leak or just built up condensation – moisture on the cool skylight surface. Depending on the skylight design, especially modern ones, some of them have condensation drip trays that collect extra moisture.
The best way to determine a skylight leak is to do it from a vantage point indoors. Look very closely at where water stains originate inside the building – trace stains to their highest point. The leak will likely be at the highest point from the wet spot.

Homeowners can have trouble determining exactly where the skylight leak is occurring, sometimes simply slather caulk or roof cement all over everything in sight. This is obviously not the best way to do it and can not only value your home but also can cause lasting damage. In addition, when professional roofers are called in, a roof-cement slathered skylight that is still leaking may be even more difficult to diagnose.
If the skylight leak is at the roof flashing, it may be possible to do a temporary repair using roof cement around the perimeter of the unit. While this can be used if a roofer cannot be contacted immediately, the best solution is to remove the shingles near the skylight and install a news properly.

Modern skylights

Modern skylights have been designed by their manufacturers to make the window as simple as possible. As a backup to prevent leaks around skylights, during the installation process, roofers usually also install flashing which are lips to direct water away from the sealed area. It is a good idea to seal the skylight curb and surrounding roof area with a bituminous membrane.

Older bubble-type skylights that were mounted flush with the roof surface are notorious leakers because they relied entirely on sealants between shingles and the skylight. Newer curbed skylights are much more reliable.
Indoors, if the ceiling drywall is badly leaking, it is best to remove the damaged drywall material completely, remove any wet or stained fibreglass insulation, and clean the ceiling area. It is always best to get a professional contractor to do this, rather than a DYI project.

What Can You Do To Prevent Skylight Leak?

Many if not all skylight leaks can be prevented through seasonal roof inspection. A roofing contractor will look for damage to the shingles, and gutters, but will also check the flashings for holes, cracks, or other signs of damage or deterioration. They should also check the interior of the house for issues that could be causing your problems. It is best to schedule roof inspections during the Spring or Summer to make sure your home hasn’t sustained any damage during the harsher winter months.

Roofing Maintenance

Taking care of your roof with regular check-ups is a great way to prevent skylight leaks. Roof maintenance is especially important around winter time, more so than in other months because of the damage, the cold can do to the skylight and a roof in general. This is largely due to the threat of ice dams, which can cause costly damage.
First, after a particularly heavy snowstorm, you should clear your roof of snow as quickly as possible. Quick snow removal does not allow precipitation time to melt and refreeze on the roof, creating ice dams. Ice dams can block drainage to the point that moisture can seep into the home through the roof and skylight.

Adequate Ventilation

Another factor to consider with skylight leaks is the humidity level in the highest floor of your home. Too much humidity in the air, which can come from the laundry room or bathroom. This can cause condensation on skylight glass while leading to leaks or even cracks around the frame. Ask your roofing contractor to suggest an appropriate ventilation system or dehumidifier for your home to prevent condensation.
If you hire an inexperienced roofing who is not familiar with skylight installation, then you can be in trouble down the road. If the skylight was installed on an older roof as a retrofit, and especially if the installer did not install the skylight properly, leaks at the skylight are likely. Always ask the roofer about their experience with skylights.

Hire a Professional Roofer to Help

Skylight leaks can be very difficult to repair, and we don’t recommend you do it yourself. If done poorly it can lead to significant interior and exterior damage. Instead, call for the advice of a professional. It will be cheaper in the long run and will prevent you from a lot of headaches.

Conclusion

If you notice leaks around your skylight, contact Cambie Roofing, a family owned & operated local roofing contractor with decades of experience in residential and commercial roofing. We’ll evaluate your skylight and surrounding shingles and recommend repairs that will fit your budget and remedy your water problems.

How A New Roof Can Increase Your Sale Value

How A New Roof Can Increase Your Sale Value

by with No Comment Roofing

If you ask most Real Estate agents, add new roofing before attempting to sell significantly increases the value of your home and makes it appealing to buyers. By increasing the value of your home, you actually make money on your repairs as the resell value increases more than 100% of your roof. In 2018, a survey in the United States found that roofing replacement added an average resale value of $14,214. Roughly the same amount of money could be expected – if not more – to be added to in Canada.
While nobody likes to spend money replacing or repairing their roof, when you’re about to sell, it makes a lot of financial sense, especially when you compare to other house projects. In fact, mending the roof offers a better return on investment than an addition to the master bedroom, major kitchen remodel, deck installation, or a bathroom remodel.
When a buyer makes an offer for your home, they assume the roof isn’t leaky or in need of fixing. If it does need repairing, and the buyer does their due diligence, they can often successfully negotiate the price down. If you’re on the fence about installing a new roof, consider these facts in making your decision.

Beautification

Buying a home is as much of a emotional investment as an financial one which is why aesthetics matter. If your home has a roof that’s shabby, ugly and clearly in need of replacement, buyers will take note. Obviously nobody wants to buy an ugly home, and a roof is such a big part of that.
If a buyer needs to take the price of a new roof into account when purchasing a home, plus the headache that comes with it, he or she will likely be enticed to shop elsewhere. While, on the flip side, a new a roof can pique buyer interest and make your home stand out in your neighbourhood. If someone in your area is selling their home at a similar price, it can give you the edge and can even spark a bidding war.

Buy A Transferrable Warranty

Buying a home can be a stressful experience. It is often one of the largest purchases someone will make in their lifetime which is why reassurance is a good thing. With the right roof warranty, it can give the new owner peace of mind that things won’t go wrong. Nobody likes surprises which is why if you can transfer the warranty to the new owner, it will likely give the buyer reassurance that they are making the right decision. Since standard warranties for asphalt shingles used to be 15-20 years and premium-quality asphalt shingles today offer warranties as long as 50 years, sometimes these warranties outlast their current occupants. Ask your roofer if you can transfer your warranty to the new owner.
A transferable warranty can mean a lifetime of not having to pay for roofing repairs. Buyers can be willing to pay more to own a home with a roof that will come with warranty. A roof warranty can add more value to a home than one without a warranty, especially if it is the difference between a standard and premium roof.

Increased Energy Efficiency

New roofs are more energy efficient then they once were which means that along with a warranty, a great-looking roof, the owners will save money on heat as well. Increased energy efficiency can increase the appeal of a home, because it means savings in the long run. In addition, many people, especially in the younger generation are more environmental conscious and having an energy efficient roof fits in with their lifestyle and values more than an older home.

Reduces Maintained

An old roof can cause trouble for future homeowners. Old roofs tend to leak, lose shingles in a storm, damage siding, and break easier than new roofs. For a prospective buyer, these potential dangers of an old roof might be enough to encourage them to buy elsewhere. Even if there is nothing wrong with the old roof, a savvy buyer will realize that older roofs are not as well built as newer ones and will most likely cause problems in a few short years. A newer roof will translate into lesser maintenance costs for the new owners overall, giving them less of a headache – both financially and emotionally.

Other Factors To Think About

Since it’s not an exact science, there are many miscellanies variables that go into appraising a home. If you can give the buyers as much data as possible it will likely increase the likelihood of getting your desired price for your home.
When you’re getting your home appraised, he or she will want to see receipts of the new roof, as well as information about its materials, construction, and warranties. The more information the appraiser has on the roof, the more likely you will see an increase in value.

Conclusion

Your roof has a lot of responsibilities to bare. It protects your entire home, its contents, and its occupants from the external environment.
When a house goes on the market, the roof is the most visible features to everyone driving down the block. A roof in poor condition can quickly stop any sale even before the negotiation has started. That’s why it’s smart to replace an old roof with a new one even before you put it on the market.
A new roof is a big investment and you should take the time to find a professional trustworthy contractor to complete the job. Give us a call at Cambie Roofing where we put customer service first and never sacrificing quality for price and guarantee you’ll be satisfied with the job.

Earthquake Proof Roof

Can A Roof Be Earthquake Proof?

by with No Comment Roofing

It’s common knowledge that Vancouver is due for a large and devastating earthquake. Thankfully all types of builders recognize this and are continually trying to seismic upgrade all our buildings. A large part of that is, of course, our roofs. If a roof collapses during an earthquake, it can kill or injury those inside. During the design and construction process of a roof there are earthquake resistant features. The roofer can apply which would increase enormously the chances of survival of both buildings and their occupants which we will cover. Let’s see more about how to make Earthquake Proof Roof?

What is an Earthquake?

The earth is made up of plates floating on the soft centre of the earth. Which consists of heavier molten rock and molten iron. The plates are not one solid piece but are separated by cracks. Which are known as faults and trenches which can press or expand together into mountains and valleys. These separate plates move slowly from a combination of forces in the Earth’s core, gravitational forces, and centrifugal forces from the Earth’s rotation.
Some plates are moving apart, for example in ocean trenches, where molten material pushes up and shoves the plates apart while others are bumping into each other head-on. The Cascadia fault, for example, which goes from northern Vancouver Island to Northern California is a very long, sloping subduction zone where the Explorer, Juan de Fuca, and Gorda plates all move to the east and slide below the much larger mostly continental North American Plate. If the movement was steady, about a millimetre or so a year, it wouldn’t matter. However, the plates tend to jam.

What makes a building or structure fail in earthquakes?

An Earthquake can be one sudden movement, or it can be a series of movements at short intervals. It can move the land up and down or it can move it from side to side.
Buildings are not necessarily resistant to side-to-side shifts. Unless this has been taken into account during the design and construction phase of the building process. A building might be perfectly stable until a severe earthquake hits. It is this side-to-side sift that generally causes the worst damage, often collapsing poor buildings on the first shock wave.

The side-to-side shift can be worse if the shocks come in waves, and can vibrate like a huge tuning fork, each new sway bigger than the last, until the building collapses. Often when more weight has been added to a building because of a heavy roof or more floors the greater the risk of failure. This extra weight produces great forces on the structure and helps it collapse. As one might expect, massive buildings like skyscrapers attract more seismic forces while smaller buildings with lighter roofs respond better to earthquake forces.

Luckily, the overall weight of a building and its contents can be calculated fairly accurately and can be accounted for in engineering design –these loads are called static loads. Wind and earthquake forces can change suddenly and unpredictably –these are called dynamic loads. The engineer must design a structure to withstand dynamic loads that may be highly variable over a very short period of time, a much more difficult task than designing for static loads alone. In Vancouver, the general awareness of earthquake danger is only a few decades old, many older buildings and roofs were not designed to stand up against the dynamic loads caused by earthquakes.

Is it Possible to Build A completely Earthquake Proof Roof?

There are, of course, roofing techniques that can be used to create a very sound roof that will endure a small or even strong quake. However, no building or roof is completely earthquake proof. During a severe earthquake, even the best-engineered building may suffer severe damage.
Most modern buildings are designed to support a vertical and dynamic load in order to support the walls and roof to keep them standing. One way to make a building more resistant to these lateral forces is to tie the walls, floor, roof, and foundations into a rigid box that holds together when shaken by a quake.

So What’s The Solution?

Because earthquakes are a function of mass shifting, all other structural elements being equal. The lighter the roof the lower the center of mass and, therefore, less likely it is to collapse or crumble. This means that roofs made out of wood tiles or asphalt are better than, say, brick, tile, or a heavy metal roof.
Lighter walls also have the advantage of exerting less force onto a building’s support system. But another good reason is that lighter wall construction tends to be more physically flexible. Which allows for more movement at the joints and throughout the structural members when an earthquake hits.

Many Vancouver builders use reinforced concrete. Where the steel reinforcement provides the tension-resistant qualities of the building. Which is able to absorb the shaking from an earthquake. A good analogy is an old car made in the 50s can better withstand an impact with minimum damage. However is more likely injure the occupants as the shift in mass travels through the car to the person. Modern cars crumble easier in an accident, absorbing the shock so the person doesn’t have to. This is much like a modern-day roof.

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.
