How Colour Affects Your Roofing Choice In Vancouver

by Roof Systems

As you drive through your Vancouver neighbourhood, the colour of a roof is probably the last thing on your mind. In fact, you will probably only notice a roof if it’s out of place or doesn’t look right. Well, allow us to explain why you should mind about your roofing in Vancouver. Yes, the roof colour in Vancouver tends to blend into the background of the landscape, but did you know your home’s roofing colour affects your home in more ways than one? In this blog post, we explore why the colour of your roof matters.

Vancouver Roofing: Light or Dark Colours?

Unfortunately, there’s no straightforward answer to which is better: light roofs or dark roofs.Ultimately, the best roof colour for your home is the one you like the best and the one that fits in with your neighbouring roofs. But there is a little more than just aesthetics when it comes to roofing colour choices in Vancouver.

How Roof Colour Reflects or Absorbs Heat

Did you know roof colour affects your home’s internal temperature?  In general, light-coloured roofs reflect away heat from the sun, while dark-coloured roofs absorb much of that heat and transfer it into the rooms below.
Obviously, if you have a lighter-coloured roof, your home absorbs less heat through the roof during summertime. As a result, your air conditioner operates more efficiently, uses less energy, and leads to lower utility bills.
In contrast, a dark roof likely raises the temperature inside your home’s highest rooms. Your cooling system works harder to compensate for the extra heat, and your bills slowly rise.
However during the colder months, the reverse is true. A dark roof brings in more heat from the sun than a light roof. This feature makes dark roofs advantageous in colder climates with long winters and short summers.
Thankfully in Vancouver we live in a temperate climate which means that there aren’t as hug fluctuations in temperature as there are in other cities. In Toronto, for example, you get extremely humid summers and bitter cold winter months.
In Vancouver, we’re more likely to have worry about the colder months but we are also seeing hotter summers in recent years so we may seem lighter roofs becoming more popular.
Or course, colour isn’t the only aspect of your roof that affects home temperature but it is a larger factor.
The roofing material also affects how your roof reflects or absorbs the sunlight. For example, asphalt shingles are less reflective than metal or rubber roofing. This quality means even tan asphalt shingles may welcome more heat into your home than a dark brown metal roof.

How Roof Colour Affects Snow Melt

Now, let’s consider how snow, another huge factor affects the equation. Because dark roofs absorb more heat, they can also help melt snow but does it actually help enough for you to take into consideration?
First, consider Vancouver has fewer sunny daylight hours during the cold winter months. And less sunlight exposure means less sun beating down on a roof and less time for the roof to absorb that heat.
Next, remember that even dark-coloured roofs may not actually appear black during the winter because they’re covered in snow. Snow actually reflects much of the sunlight before it can reach the roof so the dark roof underneath cannot absorb heat and melt the snow. This means dark-coloured roofs may have a small snowmelt effect but not a sizeable one.
Similarly, if your roof experiences winter problems like ice dams, your roof colour probably isn’t the primary culprit. More likely, insufficient attic insulation and poor roof ventilation create the problem.

Location 

Which part of your roof gets the most sunlight? Does the front of your home face north? Is the sun blocked by taller buildings or maybe you are high up on a hill? Sunlight can affect the appearance of your roof. Because of how far north we are in the hemisphere, the sun can bring out cool, blue hues while in southerly regions, roofs can appear more orange. These variations can completely change the look of a roof.

Roof Design

the architectural style and materials of your home should be kept in mind when deciding on a roof colour. Also what colour roofs are your neighbours?
Your home will look awkward if your roof sticks out like a sore thumb in your neighbourhood. There might actually be homeowner associations or subdivision rules about how your roof should look so remember to check with your neighbours before doing any major work.
Lastly, You should keep in mind that, like paint in a room, dark roofs make a home look smaller and light colours make a home look larger.

Last Thoughts in Vancouver Roofing

If you have the budget, advances in modern roofing material technology mean you can likely find a colour your like in a roofing material that suits your taste without worrying too much about heat or coolness.  However, if you just want to stick with the traditional materials you should think about

Beautify Your Rooftop Balcony

4 Tips On How To Beautify Your Rooftop Balcony

by with No Comment Roofing

Rooftop patios or terraces are great getaway spots to host parties or family gatherings, especially in the summer when the weather is hot and the days are long.  In this blog post, we want to give you some ideas for how to make the best of your rooftop patio.
Even if your rooftop balcony isn’t large, there are some great options to make it an inviting place and a perfect place just to lounge about. By choosing the right furniture, décor, and accessories, your rooftop patio will be the envy of all.

  1. Show Off Your Views As Much As Possible

The entire reason to have a rooftop patio is to show off your view of the surrounding area. Whether that is for fireworks or just to see the city lights, you should arrange your rooftop patio in away to accommodate the view.
One option is to put in glass rails or panels so it won’t obstruct anything. Also, be sure you’re not getting in the way of the view when placing furniture, awnings or umbrellas.
An alternative possibility is using a glass enclosure. Although they’re more expensive, they’re also very worth the investment, especially since it will allow you to use your terrace year-round. Additionally, this will help the space capture more light, giving it the appearance of being more spacious.

  1. Choose The Right Furniture

You’ll have to think about the furniture that you’re going to use to decorate your rooftop patio. Make sure the furniture you buy matches to give a unified look to your outdoor space.
Hammocks and hanging chairs are very common for terraces, and for good reason – the are extremely comfortable. If you don’t have a lot of storage space available, we recommend choosing folding chairs and lounge chairs, and hammocks. That way, when you have to store them for the winter, they’ll hardly take up any space.
If you are particularly crafty, you could also consider making the furniture yourself, which is very common in rest and relaxation areas. Pallets are great for this project; you just have to sand them before using them. If you like its natural colour, you won’t even have to paint or coat them.
You’ll want to choose materials and a design that are made to last. Higher pitched roofs tend to last longer.  Also, keep in mind that some materials need more care than others, so think about that before buying. You’ll also want to consider the material. Natural fibres like rattan or wicker tend to look great outdoors. They add a simple and very natural touch.

  1. Using The Right Accessories On Your Rooftop Patio

We touched on this but in this section, we’ll dive a little deeper into how you should place your furniture and other objects. This is especially difficult if you have bulky furniture or space is limited. However, if you set up a small space well, it will make it look more spacious than it really is.
If you are one of the lucky ones to have a large rooftop balcony, you can try to divide it into the following sections:
Lounging area: you can use sofas, hammocks, chairs to gather with friends and family. Umbrellas will shade you from the harsh sunlight.
Eating area: set up chairs, sofa, some cushions, and a low table to have an afternoon snack, lunch or dinner.
Garden area: plants and trees are fundamental to greenify your rooftop patio. They will make your rooftop patio look natural and colourful.
Dividing: If you have enough space, you can divide your rooftop patio or terrace into zones which will give it a beautiful clean and organize look.
It’s important to keep the area tidy and in order so it’s inviting and appealing to your guests.

  1. Accessories Are Important

When it comes to accessorizing your Rooftop Balcony, some extras you can add are pergolas, umbrellas or awnings. Sunlight hits rooftops more directly, so it’s important to protect yourself from the elements, especially if you plan to use them during the middle of the day.
Another thing we can add to our terrace are textiles, like cushion covers, which are essential accessories for the rooftop. You might also want to consider rugs, which are great for the rest and relaxation area. Just remember to take anything inside that you don’t want to get wet.
Lastly, consider light bulbs as they make great decorations and can allow you to stay late into the night even when the sun fades. You don’t have to get buy fancy or expensive lights but a few well placed soft-glow lights can really make a difference to the space.

The Bottom Line

As you can see, decorating your Rooftop Balcony doesn’t have to be difficult. You just have to set it up in a way that takes advantage of the space and choose a decorative style that matches your tastes and, preferably, your home’s interior.
If you have a rooftop patio, you should make sure that it is well maintained by having a roof inspection at least once a year to ensure that you enjoy the space for years to come.
If you need a roof replacement from a reputable contractor, call our team at Cambie Roofing. We are happy to help with any questions you may have about rooftop patios.  We look forward to hearing from you and assisting with your roofing needs.

spring cleaning tips for your roof

5 Quick Tips to Spring Clean Your Roof

by with No Comment Roofing

It’s almost March, and the weather is finally starting to warm up. As it starts to rain less, you’re probably getting ready for that dreaded spring cleaning when you clear out the garage, tidy up the basement, dust the windows, and overall get your home ready for sunny days.
While spring cleaning is important, there’s always one part of the house many people forget needs some spring cleaning attention too and that’s your roof!
Bad weather may have left your roof worse for wear, and there are a few things you can do to get it all tidied up for the rest of the year.
Here are some spring cleaning tips for your roof.

Check Your Guttering And Downpipes

The winter months can cause problems for your guttering, pipes and other drainage on your home and checking these as part of your roof top spring cleaning should be incorporated to avoid long term harm to your roof, walls, and structure.
If there’s been a lot of rain and wind then gutters and pipes may have become loose or detached through damaged joints and brackets. Also, the gutters can get clogged up from debris.
Moss, leaves and even loose shingles can be shifted in poor weather conditions and find their way into your drainage system. This debris can be the cause of blockages in the pipes which in turn can lead to inadequate drainage or overflowing water, and even flooding.

Damaging Tree Branches

If any branches fell on your roof over the winter, make sure to clear them off as soon as possible. You’ll probably be able to handle small twigs and branches by yourself, but you might consider calling a professional to take care of the larger ones. The longer they stay on your roof, the more likely they are to puncture holes through shingles, causing water damage and leaks.
It’s also a good idea to go around and trim any overhanging tree branches that could pose a problem in the future. If there are any looming over your roof that look like they might hit your roof, you’ll want to take care of them now that the weather is nice, and before they actually fall.

Wash Off Mold And Mildew

Mold and mildew can be very dangerous if they’re allowed to live on your roof. Make sure to check for signs of them.  You’ll see discoloured streaks on your roof if there’s anything growing. If you do see mold, you can treat the problem with a variety of solutions made to kill the growth. Generally you can pick these products up at your local hardware or roofing store.

Check Around Your Chimney and Vents

Be sure to check around the chimney and vents for signs of damage and disrepair that might have occurred through the winter weather. Heavy storms or fluctuations in temperature can have an effect on seals and flashing, shifting or damaging material which could lead to leaks in the future.
One easy thing you can do is go into your attic and check from the inside for any light which may be coming through cracks or gaps in the roof.
Lastly, if you have a skylight, you should inspecting around the edges for similar signs of damage.

Check for Broken or Missing Shingles

Snow, rain, storms and extreme temperatures can, cause shingles to degrade and become damaged. As the shingles are important for maintaining the watertight properties of your roof, it’s important to inspect for any areas where they may have broken or gone missing.
If possible, you want to repair or replace the shingles as soon as possible as water damage can be costly to repair. You can spot potential cracks or breakages in asphalt shingles as there will be areas or lines that appear black or darker than the rest.
Shingles that have come away altogether will likewise cause deficiency in the watertight properties of the roof, while also having the additional problem of potentially ending up in your gutter which, as we’ve discussed, can cause additional headaches.

Conclusion

We hope these tips help you treat and protect your roof and your home from damage. It can be time consuming and annoying, however, the more often you inspect and take care of your roof, the longer it will last, and the less you’ll have to spend on it over time.

Roofing Tips For The Winter

by with No Comment Roof RepairRoof SystemsRoofing Services

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

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

What to Expect When Roofing in Winter

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

Winter Safety Is The Most Important

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

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

Working in the Winter

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

The Weigh Of Your Roof

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

Equipment and Materials

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

Asphalt shingles

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

Types of Roofing Materials

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

Conclusion

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

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.

And perform maintenance to save you the trouble of dealing with an earthquake or any other possible calamity. 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.

How To Protect Your Roof From Pests

How To Protect Your Roof From Pests

by with No Comment Roof Repair

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

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

Know the Signs of Infestation

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

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

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

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

Pest Removal Methods

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

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

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

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

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

Best Methods For Preventing Pests From Coming Back

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

Seal it Tight:

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

Clean Your Gutters:

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

Trim Back Foliage:

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

Protect Your Roof With Nets:

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

Conclusion

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

Roof Warranties

The Ins and Outs of Roof Warranties

by with No Comment 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.
