Types of Commerical and Industrial Flat Roofs

When you think about a roof, two words probably pop immediately to mind: slopes and shingles.

Indeed, the majority of residential homes probably have what you might call a “classic” roof system – typical asphalt shingles sat atop a network of sloping triangles, with gutters, downspouts, and eaves taking rainwater elsewhere.

Now, picture in your mind a typical commercial or industrial building or establishment. Does it have a flat roof or a sloped roof? Probably flat, right?

Let’s take a look at why.


Commercial Roofs Vs. Residential Roofs

Around 75% of all homes in North America have shingled roofs. They’re relatively cost-effective to install, they’re functional, and the general consensus is that they look really good.

That being said, the majority of commercial and industrial buildings have flat roofs. The roofs of larger buildings and complexes face different challenges than small residential roofs, and often need to be built differently.

For example: with little to no slope, water and drainage present a big issue. Any water, debris, or material left on a flat roof can lead to severe damage due to sinking or plugged drains, which is a key reason why regular maintenance is so important. It’s even more important, though, that a commercial roof is built and installed properly by knowledgeable, licensed professionals.

With that in mind, let’s take a look at different types of commercial and industrial flat roofing.


Different Types of Commercial and Industrial Flat Roofing

Built-Up Roofing

Built-up roofing (BUR) is a type of roofing system commonly used on low-slope or flat roofs. It’s been in use for over a century, which should tell you all you need to know about its reliability and longevity. It consists of multiple layers of materials that create a durable and waterproof barrier:

  • Base sheets, which are fastened directly to the roof deck and offer a foundation for the subsequent layers
  • Felts/fabrics – usually made of fiberglass – which are laid atop the base sheet
  • Bitumen (asphalt or coal tar), which is applied between the layers of felt and acts as as an adhesive and waterproofing agent
  • Surfacing, which varies depending on the project, can be gravel, mineral granules, or a smooth coating


Modified Bitumen Roofing


Modified bitumen roofing is a type of roofing material that is well-suited for flat or low-slope roofs. It’s an evolution of the traditional built-up roofing system, but with improved flexibility and resistance to environmental factors like temperature changes and sunlight

Modified bitumen roofing sheets are composed of asphalt that has been modified with polymers or rubber to improve its elasticity and durability. The sheets are versatile, and can be installed via torch application, self-adhering, or cold-applied, and often have a plasticky or rubbery quality

Valued for its reliability, durability, and ease of maintenance, modified bitumen roofing, when properly installed, is resistant to tears, punctures, and weathering, making it a suitable choice for harsher climates. It also provides better insulation than most traditional BUR systems.


Ethylene Propylene Diene Monomer (EPDM) Roofing

EPDM is a type of lightweight synthetic rubber roofing membrane widely used on low-slope buildings. EPDM is popular due to its durability, versatility, and ease of installation. It’s resistant to heat and weathering and is available in white or black, depending on sunlight and insulation needs.

There are several more benefits to EPDM roofing, especially in commercial or industrial flat roofing systems, including its cost-effectiveness, ease of installation, relatively low maintenance, and waterproofing qualities


Thermoplastic Polyolefin (TPO) Roofing


TPO is a type of single-ply roofing membrane that is one of the fastest-growing choices for commercial and industrial flat roofs. It’s known for its heat-reflective properties and energy efficiency. Consisting of rubber and polypropylene that are polymerized together, it can be fastened to your roof deck mechanically, adhered, or heat-welded into place.

TPO is designed to be flexible, which helps it accommodate the building’s movement and settling. Resistant to mold growth, dirt accumulation, and punctures, TPO roofs are noted for their ability to withstand chemical exposure, ultraviolet light, and ozone. They’re also energy efficient, modern, and cost-effective.


Polyvinyl Chloride (PVC) Roofing

PVC is a type of single-ply thermoplastic membrane widely used on commercial and industrial flat or low-slope roofs. PVC has been a popular choice in the roofing industry due to its durability, chemical resistance, and fire resistance properties.

A PVC roofing membrane typically consists of two layers of PVC with a polyester reinforcement scrim sandwiched between them. This construction enhances the membrane’s strength and durability. Like TPO, PVC roofing is highly reflective and energy efficient, particularly when finished in light colours. This reflectivity helps in reducing the building’s cooling demands, thereby lowering energy costs.

Overall, PVC roofing provides a robust, long-lasting solution for protecting a variety of buildings with low-slope or flat roofs, combining high performance with low maintenance needs.

Spray Polyurethane Foam (SPF) Roofing

SPF is a type of roofing system that is applied as a liquid spray which expands into a foam, creating a solid layer across an existing roof. Since the foam is sprayed on as a liquid, it’s well-suited for unusually-shaped roofs because it forms a single, continuous membrane that covers the entire roof, without seams or joints. This virtually eliminates any waterproofing problems associated with seam failures in other roofing systems.

On top of that, SPF is an excellent insulator, a durable, damage-resistant surface, and is considered relatively eco-friendly; however, it requires maintenance and inspections, and it takes specific weather conditions (and a lot of skill) to install.

What is TPO roofing?

What is TPO roofing?

What is TPO roofing?

When it comes to choosing the right roofing option, there are so many choices on today’s market it can get a little overwhelming. In this blog post we are going to answer the question ‘what is TPO roofing?’ – as well as dive into the advantages and disadvantages, what it is, how to install it and if it’s the right choice for you. TPO stands for Thermoplastic Olefin which is a single-ply roofing material made from rubber and reinforcing fillers.

TPO is installed in large sheets that are welded together at the seams using heat. This achieves a seamless and water resistant finish. TPO is typically used for commercial and industrial projects but has been gaining popularity in residential projects.

TPO roofing advantages

Durability: TPO roofing is recognized as an extremely durable roofing material. Because of this, it is favoured in climates with different weather conditions such as intense rainfall, strong winds, hail and extreme temperatures – both hot and cold. The materials found in TPO can withstand tears and punctures caused by these weather conditions.

Cost-Effective: TPO roofing is a very popular choice for those looking to keep costs relatively low. The initial installation cost is low and because of its long lifespan, you won’t be spending a lot of money on maintenance or repairs either.

Low Maintenance & Long Lasting: As mentioned above, TPO roofing is low maintenance. If you want a roofing system installed that doesn’t require much upkeep then TPO roofing might be a good choice. TPO is resistant to chemicals and is less likely to support algae growth.

Environmentally Friendly: Because TPO is 100% recyclable, it is considered an environmentally friendly option. So even when the time comes that it does need replacing, your materials will be recycled. So if you’re looking to reduce your environmental impact, opt for TPO.

TPO roofing disadvantages

Limited aesthetic options: TPO roofing materials can be found in some colours but the selection is not extensive. So if you’re looking for a specific colour to match your aesthetic preferences, TPO might not work for you.

Welding Complexity: Proper installation of TPO roofing requires skillful heat welding of seams. If not done correctly, seam failures can occur, leading to leaks and other issues. It’s important to hire the experts at Cambie Roofing as this is not a DIY project.

Variability in Quality: The quality of TPO membranes can vary between manufacturers. It’s crucial to select a reputable TPO product from a trusted manufacturer to ensure the best performance. The experts at Cambie Roofing choose only the best materials so not to worry!
Despite these disadvantages, TPO roofing is a very popular choice thanks to its reliability, cost-effectiveness and environmental benefits.

Installation process

It is recommended you hire the professionals at Cambie Roofing to install your TPO roofing system. To do so, this system is installed as a single-ply membrane. Firstly, we will prepare your existing roof surface by extensively cleaning it, as well as remove debris. Then we will install insulation to ensure energy efficiency, while providing a stable layer for the TPO membrane.

Next, we will lay out the TPO sheets and attach them together using professional adhesives.

After this, we will ensure all flashing and detail work is perfected to ensure the entire roof is waterproof. Lastly, our qualified team members will perform an inspection to ensure that the roofing system meets all quality standards.

Final thoughts

There are some factors to consider when choosing a roofing system that is best for you. TPO is suitable for most commercial and industrial projects however it can be used on residential builds as well. Take into consideration your budget, climate, building type, local building codes and your overall aesthetic preferences when considering TPO. This type of roofing is durable, emergency efficient, cost effective and easy to maintain. If TPO does align with your specific requirements, give us a call today and we will provide you with a free estimate. A properly installed and maintained roof will last your home or commercial building for years to come.

Beautify your rooftop patio

Beautify your rooftop patio

Beautify your rooftop patio

Whether you own a home or a commercial property, a great way to maximize your outdoor space is to turn your rooftop into a picturesque patio! These urban oasis’s have gained popularity recently, whether it be a small garden or spacious terrace, there are many options. All it takes is a little creativity and groundwork to determine how to beautify your rooftop patio. For example, many commercial business owners like retail stores have optimized their rooftops by turning them into welcoming sitting areas – for their clients and/or employees. In this blog post, we will dive into five ways you can elevate your rooftop by transforming it into a unique patio.

1. Go green

You don’t have to be a green thumb in order to transform your rooftop patio into a beautiful green space. Adding a variety of plants to your outdoor patio will not only compliment it and make it more visually appealing, it will bring fresh air and habits for local wildlife such as birds right to your door. It can be as easy as investing in a mix of potted plants and hanging baskets. Or, you can take it a step further by creating a garden and installing grass if possible. Once your greenery is set, grab some garden decor, a bird bath and some nice outdoor lights for final touches! It’s that easy to beautify your rooftop patio.

2. Make it lounge-worthy

If you’re the owner of a commercial property and you’re lucky enough to have a rooftop patio at your business, make the most of it for yourself, employees and potentially your customers! (Or make it an exclusive perk for your employees) Let’s say you’ve added some greenery already, the next step is making it a relaxing oasis where you can take your breaks! Cozy seating is a must. No we don’t mean just add some lawn chairs and call it a day, choose some versatile options. This includes outdoor modular sofas, lounge chairs and weather resistant floor cushions. Make this space a unique spot that promotes relaxation! Throw in an outdoor rug, throw pillows and some citronella candles and you’re good to go.

3. Privacy is key

If your building is located in a high-traffic area and it feels like there’s always something going on, you might want your rooftop patio to be a place of tranquility and calmness. In order to achieve this vibe, you will want to prioritize privacy. To do so, you can easily install privacy screens and/or dividers. If your business is situated along a busy street, you can make it so when on the rooftop, you are not exposed to the traffic. In addition to the privacy screens, pick up some tall planters to help beautify the space along the dividers.

4. It’s all in the decor

Make your rooftop patio your own with thoughtfully selected decor! If you will be enjoying the patio after sunset, you will want to find lighting such as string lights, solar-powered path lights, lanterns and more. There are a variety of lighting options available depending on what type of mood you’re trying to create. Next, you’ll want to add some homey touches. If that means 10 garden gnomes, so be it! You can find other decorations at your local home store such as sculptures, water fountains, bird feeders/baths, rock art, glass ornaments and more. If your building allows it, you can add a propane fire pit! This can turn your rooftop patio into the perfect place to host team building events, after hour networking events and everything in between.

5. Protect against the elements

It’s important to consider weather protection when designing your rooftop patio. Depending on where you live, climate plays a massive role when it comes to choosing things for your rooftop. You will want to ensure your roof’s structural integrity is perfect before designing your dream rooftop. You can consult the professionals at Cambie Roofing if you are concerned about this. Next, be sure to install shaded elements on your patio to protect against things like excessive rain, sun and/or wind. If you want to make your rooftop usable in the colder months, maybe you want to install outdoor heaters. If it gets extremely hot in the warmer months, consider installing water misters. Finally, make sure everything you purchase for your roof is actually weather resistant. Taking these steps will ensure you can enjoy your rooftop patio at any time during the year.


There are many ways to beautify your rooftop patio! All it takes is a bit of planning and some insight from a professional to achieve the best look and ensure long lasting results. We know how easy it is to become overwhelmed with the urban hustle and bustle, so making a safe and relaxing space for you and your employees is of utmost importance. Add some greenery, make it lounge-worthy, add some privacy elements, incorporate decor and ensure its protected from the elements!

Commercial Roofs: Balancing Functionality and Aesthetics.

Commercial Roofs: Balancing Functionality and Aesthetics

Commercial Roofs: Balancing Functionality and Aesthetics

Whether you’re looking to upgrade your current commercial roof or you’re starting from scratch, it’s important to consider both functionality and aesthetics. The roof of your commercial property plays a significant role in the overall look and feel of the entire building. While the main role of your roof is to protect what’s inside your building, having both a functional and aesthetically pleasing roof can have a positive impact on how people view your business. In this blog post, we will explore ways business owners can balance aesthetics and functionality when building their commercial roof.

Choose the right materials

In order to achieve total functionality, you must choose the proper materials for your roof. If you don’t choose the correct materials, your entire building structure will be compromised. When determining what type of roof is best for you, you should take into account your geographical location and your business use. Because Cambie Roofing is a Canadian-based roofing company, we know how harsh the climate can be on roofing systems. This is why we have a variety of recommendations for commercial projects.

Modified bitumen

Modified bitumen roofing is a very popular choice for commercial roofs in Canada. Using various layers of polymer and asphalt, this is a cost effective and durable option.

Thermoplastic olefin

Next, thermoplastic olefin (TPO) is an energy efficient roofing material that has grown in popularity. TPO roofs are made of single-ply membranes that are welded together to form a seal. This means no moisture is able to penetrate, allowing for a resistant roofing system.

Ethylene propylene diene monomer

Another popular roofing material used on commercial projects is ethylene propylene diene monomer (EPDM). EPDM is a synthetic rubber which is great at protecting against the elements. Whether it be harsh winds that rip through a city for an afternoon or a scorching week-long heat wave, EPDM will protect your building.

Polyvinyl chloride

Another roofing material we thought we should mention is polyvinyl chloride (PVC). This system is wonderful at deflecting the sun’s rays so if you live somewhere with plenty of sunlight, this might be the best option for you. PVC systems are also very lightweight which makes them easier to install on roofs of all sizes. Take advantage of energy efficiency for your commercial building after installing a PVC system!

Metal roofs

Lastly, if you want a low maintenance energy efficient roofing system, you should consider installing a metal roof on your commercial property. While they can be costly to install, they have a very long lifespan which will save you money on repairs down the line. Metal roofs have become very popular among Canadian business owners because they are great at withstanding harsh environmental conditions. On the other side, metal roofs have a modernized feel and can make your building stylish, energy efficient and functional.

Roofing aesthetics

Once you’ve picked out the right roofing materials and systems for your commercial building, the next step is to figure out how to make it look appealing! Whether your building has a flat roof or a sloped roof, there are simple things you can do to achieve your desired look! Are you going for a sleek and modern design or do you want your building to stick out from its surroundings? Either way, there are ways you can achieve your desired look.

Colours and designs

Do you think your roof is lacking colour? Consider installing tiles or shingles that compliment the rest of your building’s appearance. You can add various accent colours to your roofing scheme to make it stand out or just one neutral colour if you’re looking to achieve a more sleek appearance. If you want to take it a step further, consider adding designs/artwork to the roof. This has become very popular among business owners with artistic backgrounds and companies focused on things like graphic design and exterior decorators. You can search for local artists in your area who might be interested to take on an outdoor challenge.

Solar panels

Solar panels have become increasingly popular among commercial building owners. You can get the panels installed in ways that compliment the look of your building while also showing your potential customers that you care about your carbon footprint. There are plenty of ways to integrate solar panels into your roofing system while also adding style.

Inviting features

If your employees and/or customers regularly access your roof, adding some lighting can make your roof that much more inviting. This includes things like string lights, lantern lights and LED strips. Some other ideas include comfortable seating options, water fountains and greenery. These things will help improve the experience people get when they visit your roof.

Green roofing systems

One of the coolest ways you can improve the aesthetics of your commercial building is installing a green roof. Not only do these systems provide beautiful alternatives to regular roofing systems, they positively impact the environment, promote biodiversity, improve air quality, regulate your building’s temperature and so much more.


Balancing functionality and aesthetics may seem challenging when it comes to your commercial roof. It is important to consult the professionals before making any changes to your existing roof or before designing a brand new roof. The experts at Cambie Roofing can assist you with choosing the most functional materials for your project while also giving you recommendations on how to make your roof look its best.

A green roof - one of the many ways to make a commercial roof more eco-friendly.

How Can I Make My Commercial Roof More Eco-Friendly?

How Can I Make My Commercial Roof More Eco-Friendly?

Every construction project whether it’s big or small has some sort of impact on the environment – roofing included. If you’re the owner of a commercial property, choosing an eco-friendly roof upon building or replacing your current roof will not only lower your carbon footprint but it can also save you money down the road. As a business owner, the impact your roof has on the environment should be something you consider. In 2023, many builders are taking into consideration things like climate change and increased prices on supplies and energy costs. Because of this, many people with both residential and commercial buildings are seeking eco-friendly options when it comes to their roofs. In this blog post, we are going to discuss eco-friendly roofing options for commercial buildings.

Roof coatings

If you are looking for ways to make your existing commercial roof more eco-friendly, a great option to consider is adding a sustainable roof coating. These coatings are designed to reflect sunlight which means you’re spending less money to keep the inside of your building cool, especially during warmer months. There are various types of coatings but the most common ones are silicone and acrylic. Restoring your existing commercial roof is a lot less expensive than replacing the entire thing so if you’re looking for a cost effective treatment, roof coatings are the way to go. Installing a roof coating not only makes it cheaper to regulate the temperature inside of your building, it will also increase your roof’s lifespan and reduce your carbon footprint. A win-win for a commercial building owner looking to be more eco-friendly! Some roof coatings are specifically designed in lighter colours so they can reflect even more sunlight while lowering your energy bills. These simple techniques are also known as cool roofing methods and oftentimes you can find them from recycled materials which makes it even better for the environment.

Green roofs

Recently, green roofs have gained popularity among commercial building owners. These roofs are typically installed on flat roofs and when complete, they have numerous positives on the environment. Similar to roof coatings, green roofs can moderate your building’s temperature. They also promote clean air, beautify areas that might lack greenery, collect rainwater runoff and promote biodiversity. If your building can accommodate a green roof, there are plenty of things you can do with it such as creating a park for customers to enjoy, a garden to grow fresh fruit and vegetables or just a place to unwind on your own. Green roof installations are complex and require plenty of upkeep which can be costly but if you are willing to take on the challenge, you will benefit greatly from it while also making your building eco-friendly.

Consider installing skylights

A roofing addition that many people often overlook is skylights. Compared to a normal window in your building, a skylight can produce three times as much natural light. If your skylight is installed in an area that gets plenty of sunlight, this can improve energy costs as you won’t need to rely so much on artificial lighting. Depending on how they’re installed, skylights can also improve your heating and HVAC efforts. In addition, skylights provide a great opportunity for people wanting to benefit from natural sunlight throughout the work day. More natural light means happier employees and lower energy bills!

Solar panels

Converting sunlight into energy and not having to rely solely on fossil fuels is one of the best ways to make your roof more eco-friendly. This is done through the installation of solar panels, one of the largest growing trends when it comes to constructing and restoring both commercial and residential roofs. While solar panels can be pricey during initial installation, they will give you the power to produce your own energy without any greenhouse gases. Depending on where you’re located, many areas have started providing incentives and rebates for people looking to turn to solar energy because of the importance of renewable energy when it comes to fighting climate change. A good thing about solar panels is that once they’re installed, they don’t require a ton of maintenance.


By being more eco-friendly with your commercial roof, you are guaranteed to reduce your energy costs, increase the lifespan of your roof, see a positive return on investment and lower your carbon footprint. Sustainable roof coatings, green roofs, skylights and solar panels are just a few of the ways you can make your existing or new roof more eco-friendly. While the population starts doing their part to combat climate change, the focus shouldn’t just be on making residential roofs eco-friendly because commercial roofs are just as important. So what are you waiting for? If eco-friendly commercial roofing techniques is something you’re interested in, reach out to the experts at Cambie Roofing to learn more and discuss your options.

How To Protect Your Commercial Roof from Vancouver Storms, commercial roofing system

How To Protect Your Commercial Roof from Vancouver Storms

You know how critical the role of a commercial roofing system is to your building’s overall structural integrity. But it, too, needs protection from the elements. This is especially true during the storm season. Let’s find out How To Protect Your Commercial Roof from Vancouver Storms.

The next major storm that passes through can leave in its wake one of these three conditions:

  • Complete removal of the protective membrane
  • A breach in the protective membrane
  • Permanent deformation of the roofing materials

Any of those scenarios result in an expensive roof repair project, something you can’t afford right now. Because storms happen every year, you need comprehensive protection from the elements that won’t break your budget or require an overhaul of your commercial building.

Preventive Measures

Protecting your commercial roof from storms begins with preventive maintenance. If you make sure your roof is clean, well-maintained, and free of leaks, you’re off to a good start. Below are some other ways you can help keep it protected:

  • Hire an experienced commercial roofer to inspect your commercial building every year or two for damage that may have occurred due to ageing or neglect.
  • Ensure your roof is strong enough for the kind of weather it’s exposed to. Asphalt shingles, for example, aren’t designed to withstand high winds and heavy storms.
  • Use commercial roof coatings that protect and beautify your building at the same time.

Flat Roofs Must Be Waterproofed

Flat roofs are particularly vulnerable to damage when intense storms hit during the summer months because they heat up under direct sunlight, creating a thermal expansion in the roofing materials. Repairing a damaged flat roof is an expensive undertaking that’s best avoided by investing in commercial rubber roof coating that will protect your building for years.

Sloped Roofing is Prone to Storm Damage

High winds and falling debris can also damage asphalt shingles and other types of sloped roofing. Before the next storm season arrives, make sure any weak areas on the roof are repaired as well as any gutters and downspouts that may be clogged or blocked with debris.

Protecting Tile and Slate Roofs

Tile roofs are popular for commercial buildings because they’re durable and attractive. They can stand up to strong storms if appropriately installed – but only if their waterproofing system is maintained regularly. There’s no excuse not to, considering moisture intrusion causes more damage to tile roofs than wind-driven rain itself.

Slate roofs, too, can stand up to storms if their waterproofing system is in good working order. They’re also more fire-resistant and energy-efficient than other roofing systems.

Reinforce your EPDM Roof

EPDM rubber roofs are easy to install, durable and attractive. They can also withstand high winds if they’re correctly reinforced. Start by applying a commercial-grade silicone sealant around the perimeter of your building’s roofing membrane. Also, consider installing a metal drip edge flashing along all eaves and rakes, as well as at any penetrations – including roof drains and roof vents. The flashing should be no less than 24 inches in width and overlap the membrane by at least two inches.

Commercial roof coatings can also help prevent wind damage to your building’s EPDM rubber membrane, as well as seal leaks which may allow water infiltration over time. This helps ensure the optimum performance of the waterproofing system.

TPO Roofs Need Protection, Too

TPO roofs can also take a beating during heavy storms. This is especially true if they aren’t correctly installed and maintained. Then again, even if they are properly installed and maintained, TPO membranes can still suffer significant damage from hail impact.

For the best protection against wind-driven rain, use a commercial-grade sealant to bond the seams and all penetrations in your TPO membrane together. Also, consider installing metal drip edge flashings over all eaves and rakes.

Cut or Trim Trees Nearby

If your commercial roof is exposed to strong winds during storm season, then you need to take steps to protect it. One of the most effective strategies is to remove all trees within a hundred feet of your building. If that’s not possible due to property lines, cut back overhanging branches at least six feet from the roof.

Even small branches and twigs can cause significant damage to your commercial roofing system during heavy storms, so don’t ignore the presence of trees in proximity to your commercial building.

Dealing with Rooftop Equipment

Some commercial buildings have rooftop equipment, i.e., HVAC. The problem with this setup is that it can be damaged easily by a strong storm, causing a major headache and expensive repairs. A solution is to install special roofing anchors that secure rooftop equipment while making it more wind resistant.

Ask your HVAC installer for details on how to protect your building from the effects of storms. In fact, ask everyone you work with – from your roofing contractor to your roofing supplier – how you can help keep your building safe.

Your Location Matters

Some locations are more exposed than others. For example, roofs of buildings near the beach or in hurricane zones tend to get hit more often and harder than those in inland locations. Roofing professionals determine which areas of your state are more likely to experience windstorms, so it makes sense to work with them in adding protection to your commercial roof.

Prevent Instead of Fix

Make sure your commercial roofing system is in good shape and will stand up to the worst Mother Nature can throw at it. If you neglect it, you’ll be faced with a costly repair project – perhaps even having to replace your roof entirely.

While residential roofs don’t cost that much to repair or replace, the same can’t be said about commercial roofing. It’s much more expensive, given the size and scale of most commercial buildings.

The thing about storms is that they don’t spare anything – even the most durable or expensive roofing material. So, you’re only option is to give your roof an added layer of protection to have a fighting chance against the storm.

Prevention is your best option. Of course, it’ll cost you money, but a little upfront will go a long way to protect your investment in a commercial building. After all, there’s no way to control or stop storms – the best you can do is prepare for them.


Whatever your commercial roofing material, you can’t afford to wait until the end of the season to address damage, no matter how minor. The next storm that comes along could be too much for your roof to handle. Call a commercial roofing contractor now and protect your building from storms before they happen.

How to Protect Your Commercial Roofing from Winter in Vancouver

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.

Types of Commercial Roofing Warranties

Types of Commercial Roofing Warranties

Your commercial property needs a new roof sooner or later. You should prepare for that time to come because it’s a pricey investment. No matter how expensive the roof is on your building, it ultimately gives in to a bunch of factors beyond your control, including age and extreme weather conditions. When it’s time for a commercial roof replacement, you’re looking at spending thousands of dollars for a structure that you hope will last for at least 45 years.
So, what if something goes wrong with your newly installed commercial roof? This is where a roofing warranty comes in. You probably don’t think that much about the warranty that comes with the purchase of a new roof; you may not even be aware that you’re receiving one.

Commercial roof warranties are a requisite for any purchase and installation since it is the only way to protect your investment from faulty material or product. If there is an issue with the roofing material or its installation, the warranty provision gives you the right to compel the contractor to correct the problem without you having to pay a dime.

The installation of a new commercial roofing system entitles you to a bunch of warranty options, including:

1 – Workmanship Guarantee

The workmanship guarantee is issued by the roofing company tasked to install the new structure on your commercial building or facility. This is the type of warranty that protects the building owner from substandard workmanship as well as minor installation mistakes. For the most part, a workmanship warranty covers the cost of materials and labour needed to carry out the repair. The contractual agreement on workmanship warranty ranges from one year up to a decade of coverage.

2 – Material or Product Warranty

This commercial roofing warranty is afforded by the company that manufactures the roof materials or products that your roofer opted to use. The warranty covers any defect in the product and failure of the material to function as advertised. It is only valid if there is no evidence or indication of a faulty installation. Unlike the first type, this warranty is limited in scope. But most manufacturers try to compensate by offering up to thirty years of coverage.

3 – All-In or Full System Warranty

A full warranty is handed out by the manufacturer of the roofing product. It covers both the material used and the accessories needed for the installation of a new commercial roof. This warranty covers the materials and labour required in case a repair is needed within the prescribed period.

What You Must Know About Warranty Coverage

Many commercial property owners are clueless about the coverage details of their roof warranty. You must dig deep and review every provision in the roof installation or replacement contract. Be sure that you are fully covered. You can also talk to your insurance company about extended coverage.
You’re covered in these scenarios:

  1. Improper Installation – If the roofer is at fault with the incorrect installation of your commercial roof, you have the right to demand the leak or any other defect to be fixed at no cost.
  2. Material Defect – If the product used in a commercial roofing replacement is defective or fails after just a couple of months, then you are entitled to demand for the enforcement of the warranty. The most common product defect is the roofing membrane, but it could also be other components and parts.
  3. High Winds – The “high winds” coverage in commercial roofing warranties vary from one contract to another. You should talk to your local roofer about wind speeds in your location before you purchase additional coverage.

You’re not covered in these instances:

  1. Incorrect Repair – Resist the temptation of resolving a damage or leak if your commercial roof is still under warranty. Resolve the issue within the scope of the warranty. If you hire a roofer who chooses low-quality materials and comes up with an inferior repair job, likely, your bill won’t be covered by the warranty.
  2. Unsanctioned Alterations – A commercial roofing warranty includes a list of roofers who are allowed and qualified to perform the repairs and other alterations. If you choose someone who isn’t on that list, don’t expect the costs to be covered by the warranty.
  3. Act of God – Majority of commercial roofing warranties cover extreme weather conditions like hailstorms, high winds, and torrential rains. But the so-called “acts of God” like an earthquake, major hurricane or tornado aren’t part of it.
  4. Standing Water – Standing water on the roof is attributed to the lack of proper drainage. So, if your roof incurs damage due to standing water during the warranty period, don’t expect the repair costs to qualify for coverage.

The Importance of Commercial Roof Maintenance

Even with a commercial roofing warranty in place, you still need to have your roof regularly inspected and maintained. The lack of maintenance and regular inspection means that minor issues are ignored. You could end up voiding your warranty at the time when you need it the most.
Most commercial roofing warranties require at least one inspection every year. Only an authorized roofing contractor performs the examination. Although some commercial property owners are upset about the added burden of hiring someone to inspect the roof, it benefits them in the long run. A comprehensive inspection is the only way to find out if there are issues on the roof. That must be addressed right before they become a considerable financial burden. A timely repair not only prevents a costly replacement, but it also prevents the possibility of voiding the commercial roofing warranty.
