Vancouver roofing and metal sheet performance

You If you’re considering installing a metal roof for your home, it’s important to look at its benefits and drawbacks. You most probably are not fully aware of the metal sheet roofing performance, and you need to contrast them against other common types of roof materials. Well done! You have landed to the right place. We have broken down the pros and cons so you can make the right decision for your home.

Metal Roofing Benefits

Metal roof has a longer life expectancy than other types of roofs. Properly installed, a metal roof should last as long as the house, sealing out water, surviving high winds, and easily shedding snow. Metal is also resistant to fire, mildew, insects, and rot.

Warranties vary widely, but most companies back their products for 20 to 50 years. The performance of a metal flashing directly correlates to:

  • Type of metal or alloy incorporated
  • Thickness or weight of the material
  • Protective coating applied.

Metal roofs are lightweight when you compare them with tile at 750 pounds per square or concrete tile at 900 pounds per square. Most varieties run from 50 to 150 pounds per square.
For a sheet metal roof, a waterproof membrane must be installed prior to the installation of metal flashings as a part of the metal flashing detail. To prevent leakage, contractors must install metal flashings in a manner that will ensure water sheds away from the seams.
The leading causes of leakage from sheet metal flashings include the absence of a waterproof membrane under the flashings and poor transitional detailing.
Most metal flashing installers have little knowledge of waterproof membranes or transitional detailing. An experienced roofer will install the waterproof membranes so you don’t have to worry about any leakage.

Metal Sheet Performance

Some types of metal roofing materials may be applied over an existing roof without the need to tare or add additional structural support. In fact, if you’re building a house or an addition, you can often downsize or reduce the number of roof support members.
Most metal roofing materials come in multiple-shingle sections or in 12- to 36-inch-wide panels. An experienced roofer can install these quickly.
Metal flashings are fabricated from a variety of metals and alloys: Galvanized Steel, Galvalume, Zinc, Copper. The coatings used to provide rust protection include baked enamel, silicon, and kevlar among others.
Steel and aluminum are by far the most common and sensible of available roofing materials because they are economical, hold paint finishes well, and are durable.
Aluminum is a relatively soft metal, so it is more prone to denting and damage and it is also more expensive than steel. On the flip side, aluminum won’t corrode the way steel can if the finish is compromised.
To resist wind uplift forces, installers use metal clips and concealed fasteners to secure the flashings to the building during the installation process.
Also, metal flashing details are only one part of the buildings envelope and must be incorporated into the design of transitional details. This procedure ensure the building’s protection from wind and rain.

Metal Sheet Roofing is Environmentally Friendly

Metal roofs offer substantial household energy savings and much lower lifetime costs when compared to other roofing materials. Same, Metal roofs are manufactured from as much as 60 % recycled materials and the extended lifespan translates to significant waste reduction.

Drawbacks of a Metal Roof

The variables that go into metal roofing prices are many, so much so that it is not possible to quote an exact price without a detailed inspection first. Factors like current roof condition, shape, and slope all affect price. Also, property location and roof accessibility are important considerations.
Cost can also be quite high for getting a metal roof installed compared to other roofing materials.
Labour of course is also a major factor when looking at a metal roof. However since they don’t take as long to install as a traditional roof made of asphalt or tile, the labour won’t be that expensive.
However, since metal roofs are uncommon, you should ask the roofer if they have experience installing such a roof before. You don’t want an inexperienced roofer trying to learn on your home. It can cost you time and more money than you expected.

Choosing a Look for Metal Sheets

If you do go for a metal roof, the last thing you need to consider is look. When installing a metal roof, you’ll first want to determine the fundamental design you want it to have. Residential metal roofing comes in two basic forms that are very different in appearance – sheet-like panels and shingles. Within these two categories, there are many variations, colors, and pattern.

The most familiar pattern of panel-style metal roofing, the “standing-seam roofing,” raises at every 6 or 12 inches. They are applied vertically on a roof and doesn’t attempt to look like anything other than what it is.
It has a decidedly commercial look that is favored by architects for its clean, contemporary appearance. For this reason, most modern homeowners choose them to garnish a true variety of homes, from mountain cabins to modern masterpieces. Yet, they look very out-of-place on a Colonial home.

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

Wraping it up

If you’re considering a metal roofing upgrade, you have probably done a search online, only to find that most metal roofing companies shy away from the topic of pricing.
In an effort to help property owners get a good idea of the metal sheets performance and their cost-benefit ratio, we suggest you give us a call at 604-261-1111 and we can guide you through the entire process.

Modern roofing materials

by Roof SystemsRoof Types

Modern roofing materials

Trends come and go within our society on a regular basis, this is especially noticeable with fashion. Certain things that once were in style no longer are while other things have come back into style, full force. This also applies to the look of our homes and in this blog post we will dive into all modern roofing materials as well as the do’s and don’ts when it comes to following these trends. Many modern roofing materials are not only aesthetically pleasing, they offer benefits that older materials never could.

Synthetic materials

Many homeowners and commercial building owners now opt for synthetic materials when building their roofs. This is because they offer durability while typically using recycled materials. Things like synthetic slate and shake are common choices, being made from recycled polymers. These materials are very weather resistant and also very sustainable.

So, if you’re building your roof and you want it to be environmentally friendly, choosing recycled synthetic materials is the right choice. You can find these materials in various colours and styles that all offer long-lasting protection for your home. Many people will opt for synthetic materials because they are lightweight which means they put less stress on your structure than other roofing choices. This means it’s easier to install as well as maintain.

Metal roofing systems

Metal roofs have gained popularity in recent years and not just with commercial buildings but also homes. It used to be that metal roofing systems were only used for structures like barns and industrial buildings. However, because of their style, metal roofs have joined the top modern roofing materials on the market.

Often metal roofs are made using standing seam designs which provide ample protection against all weather conditions including heavy snow and extremely hot temperatures. They also are perfect for reflecting sunlight which in turn will lower your energy bills. Metal roofs are no longer overly loud either thanks to modern installation techniques. While they can be a tad pricey upon installation, metal roofs are designed to last and they are great for being fire resistant.

Cool roofing techniques

Everyone wants to be comfortable in their homes which means it can’t be too hot. As the world continues to live with the effects of climate change, being environmentally conscious is something many are striving for. Cool roofing techniques help combat rising temperatures by using reflective materials such as coatings, tiles, shingles and more.

In turn, this helps keep your home at a more comfortable temperature while reducing your reliance on air conditioning. Having a cool roof is something to consider especially if you live in a dense urban area with plenty of neighbouring buildings. But it doesn’t stop there, cool roofs also contribute to lowering greenhouse gas emissions. This means having a cool roof will save you money on energy consumption while also being environmentally friendly! A win-win for homeowners looking to make a difference.

Solar panels

For our last modern roofing material, we are going to touch on solar panels. Another step towards sustainability is using solar panels on your roof. They carry amazing energy generating capabilities but they also offer stylish and modern architectural looks. We have already mentioned how modern roofing materials are fueled by the desire to be environmentally friendly which is why solar panels are now becoming a common necessity. Solar panels lower energy bills and reduce carbon footprints by converting sunlight into electricity. This takes away the need to rely solely on traditional energy sources. By investing in solar energy for your home, you’re investing in the future.

Conclusion

All modern roofing materials have something in common – positive environmental impacts. Nowadays you are no longer limited to historic roofing techniques that can be expensive, hard to maintain and are not good for the environment. Today, you can find roofing materials that are both stylish and modern but also good for your pocket and the environment. Whether you opt for synthetic roofing materials such as recycled slate and shake, a beautiful metal roof and/or solar panels, all of these options can be made into a beautifully designed modern roofing system.

Types of roofs

You may not take much notice of the different Types of Roofs and Roofing styles there are in Vancouver, but they can vary a lot, depending on the type of material you use and the look of the house or building. Of course with the infamous rainy weather in the city, you need something with good drainage, otherwise, you’ll have leaks that will create damage to your home. In this blog article we look at all the different types of roofing systems you can use for your home; however, keep in mind not all of these will be appropriate for Vancouver weather.

Different Types of Roofs:

Gable Roof:

Gable roof designs are one of the simpler and most common styles when it comes to roofs in Vancouver, especially.  The gable roof style looks like an upside-down V.
Pros: There are numerous advantages to the gable roof style. First, its simple design makes it easier to construct and less expensive than alternative roof types. Also, there is available space underneath the roof, allowing for an attic or a more open concept. Gable roof structures easily shed water and snow which makes them great for areas with heavy snowfall such as Canada. The steep pitch of gable roofs allows for excellent water drainage and fewer leaks. They also allow for more ventilation and provide more space for an attic or vaulted ceilings.
Cons: Gable roofs are more prone to wind damage, as they tend to be more steeply pitched than other roof types. In addition, if a roof is not adequately supported by its framing, it could be at risk of collapsing. Also, if there is too much overhang, winds underneath can actually lift the roof away from the home’s walls. This style of roof is not recommended in areas prone to tornadoes.

Flat Roof:

Flat roofs are common, especially with commercial buildings. They are definitely the most simple roof to construct because they have little to no pitch. The most common types of systems used with flat roofs are rubber.
Pros: By far the biggest advantage of using a flat roof is the expense. From the initial building and installation to the materials most often used to cover the roof, flat roofs are fairly cheap.
Cons: The biggest disadvantage to installing a flat roof is the drainage, or lack thereof, which can be a problem in Vancouver. Flat roofs do drain, but not nearly as efficiently as a roof with any kind of pitch. Therefore water has a tendency to puddle and remain on the roof, which could lead to the roofing material breaking down or to eventual leaks, particularly along the seams.

Hip Roof:

Hip roofs are a common residential style. They are more difficult to construct when compared to flat roofs and gable roofs because they have a more complicated truss and rafter structure. A hip roof style roof has four sloping sides with zero vertical walls. Hip roofs can be both square and rectangular.
Pros: Hip roofs are more stable than gable roofs because the inward slope of all four sides is what makes it more sturdy and durable.
They are excellent for high wind, rain, and snowy areas. The slant of the roof allows snow and rain to easily slide off with no standing water. Hip roofs can offer extra living space with an addition of a dormer or a crow’s nest.
Cons: Hip roofs are more expensive to build than a gable roof. It’s a more complex design that requires more building materials. Also, with the addition of a dormer, additional seams can make it easier for the water leaks to form in the valleys, if a roofing system is not properly installed.

Dutch Gable Roof

The Dutch gable roof is a combination style roof that uses design elements of both gable and hip roofs. A miniature gable roof, or “gablet”, is perched atop a traditional hip roof.
Pros: The gable can be fitted with windows for added sunlight into the top floor. It’s also a unique design that can be functional yet distinctive for the Vancouver climate.
Cons: A drawback of a hip framed roof is its reduced attic space for a given roof pitch compared to a simple gable roof.

Dome Roof:

A dome roof is polygonal with an inverted bowl shape. Dome roofs are great for adding unique and aesthetically pleasing features to any home. They are excellent choices for cupolas, gazebos or crow’s nests.
Pros: Not something you see every day, dome roofs are beautiful, unique and durable.
Cons: The complexity of a dome roof makes them expensive to construct. However, depending on the structure, a prefabricated one may be available.

Gambrel Roof:

A gambrel roof is basically how you picture a barn roof. While used on barns, it is also used in residential construction. This type of roof has the benefit of providing a good amount of space in the attic. In fact, it provides so much extra space that it is often turned into bedrooms or other living areas. The gambrel only uses two roof beams, along with gusset joints.
Pros: Since the construction is quite simple with fewer materials needed, this helps to keep the cost of a roof down. It also provides extra living space for a garret, attic or loft. Plus it’s simple to frame out. Gambrel roofs are also a great idea for outdoor sheds and storage buildings. Their shape can provide more storage without taking up more space.
Cons: The gambrel roof is not recommended for heavy wind areas or regions that receive significant snowfall. The open design can cause the roof to collapse under extreme pressure.

Mansard Roof:

A mansard roof, also known as a French roof, is a four-sided roof with a double slope on each side that meet forming a low-pitched roof. The lower slope is much steeper than the upper.
Pros: Mansard roofs can help create a great deal of extra living space. Using the space as a full attic or living quarters is very popular. The style lends itself to either open or closed dormers for more aesthetic appeal. Mansard roofs are great for people wanting the flexibility to make future home additions. When first designing and building a home, you can actually save money by having a simple mansard design to start off. This will not only add value to the house, but it also allows homeowners to easily make additions as their needs change.
Cons: A low pitched portion of a mansard roof isn’t ideal for areas receiving heavy snowfall. They also typically cost more than other roofs because of the embellishments and details that go into them. But, the added space and character can more than makeup for the extra cost of initial construction.

Sawtooth Roof

A Sawtooth roof is two or more parallel pitched roofs in which the sloped and vertical surfaces alternate. As the name suggests, the roof resembles the side of a saw blade or a graph line. Sawtooth roofs were once only used in industrial buildings. However, now they have become trendy and are now used in modern home design.
Pros: Very chic looking, this design can have windows placed in the vertical spaces of the roof, allowing more natural light inside the home. The higher peaks provide the opportunity for either attic, vaulted ceilings or loft living space. The combination of the various slopes and use of natural light make this design an excellent choice for homes with Eco-friendly conveniences, geothermal, solar panels, and radiant heating systems.
Cons: The complex design and various building materials make the Sawtooth roof much more expensive than other roof types. It’s also a high maintenance roof. Adding windows, valleys and varying slopes creates a higher chance for water leaks. For this reason, Sawtooth roofs aren’t advisable in heavy snowfall areas.

Conclusion

When building a new home or retrofitting an existing one, choosing the right kind of roof can be more difficult than you might imagine. After all, roofs do a lot more than just serve the most basic practical purpose of protecting a house and its occupants from the outside elements. For instance, a roof’s shape plays a major role in defining the overall look and style of a house. They must fit in with the character of not only the rest of the house but the entire neighbourhood as well. Roofs play a big part in providing additional living space, as well as make your home more resilient, energy-efficient, and weather-proof. So, i hope now you have get an idea about Different Types of Roofs.

Residential Roofing, Best Types of Roofs

Best Types of Roofs

In this blog post we’re going to cover the best types of roofs for your residential or commercial building.
Whether you are building your roof from scratch or patching up your existing roof a wide range of materials and types are readily available. But which one is the best for your home?
There are many types and materials to choose from which include asphalt, wood, and composite shingles, as well as slate, concrete, and clay tiles. Cost is an important factor, but it’s not the only one. Style, material weight, and installation requirements should also influence your selection. Lastly, you want your roof to blend in well with the neighbourhood. If you build a flat roof in a neighbourhood of cedar roofs, it can cause your house to stick out like a sore thumb.

Cost

A number of considerations will affect the cost of a new roof. The price of the material is the starting point, but other factors also must be considered. One is the condition of the existing roof if you are remodeling a house. If old materials must be stripped off, and if the supporting structure needs repair, that can be costly. The shape of the roof is another contributing factor. A gable roof with few or no breaks in its planes makes for a simple roofing job. A house with multiple chimneys, intersecting rooflines, turrets, skylights, or other elements will cost significantly more to roof. It’s always important to get an estimate before starting any work.

Materials

Not every roofing material can be used on every roof. A flat roof or one with a low slope may demand a surface different from one with a steeper pitch. Materials like slate and tile are very heavy, so the structure of many homes is inadequate to carry the load. Consider the following options, then talk with your roofer and get an estimate for the job.

Asphalt Shingles

This is the most commonly used of all roof materials, probably because it’s the least expensive and requires a minimum of skill to install. It’s made of a fiberglass medium that’s been impregnated with asphalt and then given a surface of sand-like granules. Two basic configurations are sold: the standard single-thickness variety and thicker, laminated products. The standard type costs roughly half as much, but laminated shingles have an appealing textured appearance and last roughly half as long.

Wood

Wood was the main choice for centuries, and it’s still a good option. Usually made of cedar, redwood, or pine, shingles are sawn or split. They have a life expectancy in the 25-year range but cost an average of twice as much.

Metal

Aluminum, steel, copper, copper-and-asphalt, and lead are all durable—and expensive—roofing surfaces. Lead and the copper/asphalt varieties are typically installed as shingles, but others are manufactured for seamed roofs consisting of vertical lengths of metal that are joined with solder. These roofs start at about $250 per square but often cost two or three times that.
Tile and Cement. The half cylinders of tile roofing are common on Spanish Colonial and Mission styles; cement and some metal roofs imitate tile’s wavy effect. All are expensive, very durable, and tend to be very heavy.

Slate

Slate is not very common in Vancouver. However, is among the most durable of all roofing materials. Not all slate is the same but the best of it will outlast the fasteners that hold it in place. Hundred-year-old slate, in fact, is often recycled for reinstallation, with the expectation it will last another century. But slate is expensive and very heavy.

Best Types of Roofs

Once you pick your material, you have to pick the style of roof you want. There are many different types but we have narrowed it down to three different types. The styles of roofs vary depending on area and taste.

Gable Roof

Gable roof designs are one of the simpler and most common styles when it comes to roofs. The gable roof style looks like an upside down. There are numerous advantages to the gable roof style. First, its simple design makes it easier to construct and less expensive than alternative roof types. There is also available space underneath the roof, allowing for an attic or a more open concept. Gable roof structures easily shed water and snow which makes them great for areas with heavy snowfall such as Canada. The steep pitch of gable roofs allows for excellent water drainage and fewer leaks. They also allow for more ventilation, and provide more space for an attic or vaulted ceilings.

Sawtooth Roof

Sawtooth roofs were once only used in industrial buildings. However, now they have become trendy and are now used in modern home design.

The higher peaks provide the opportunity for either attic, vaulted ceilings or loft living space. The combination of the various slopes and use of natural light make this design an excellent choice for homes with Eco-friendly conveniences, geothermal, solar panels, and radiant heating systems.

Flat Roof

Flat roofs are common especially with commercial buildings but can be used on residential homes as well. They are definitely the most simple roof to construct because they have little to no pitch. The most common types of systems used with flat roofs are rubber. By far the biggest advantage of using a flat roof is the expense. From the initial building and installation to the materials most often used to cover the roof, flat roofs are fairly cheap.

Choosing the Right Roof

More often than not, if you are remodeling, the existing roof of your house will determine your choice of roofing material. Should you be considering other options, you’ll want to consider not only the cost but the color, texture, weight, and durability of your alternatives, as well as what traditionally has been used on houses like yours. So, these Best Types of Roofs will help you to Decide.

The Best Roofing Options for living in Vancouver

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

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

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

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

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

How To Choose Your Roofing Materials

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

Asphalt Shingles

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

Cedar Roofing

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

Metal Roofing

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

Torch-on SBS Membrane Roofing

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

Don’t Forget about the Warranty

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

Conclusion

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

Commercial Roof Systems

Whether you are constructing a new commercial building or need to replace the roofing on an existing structure, it is important to understand the different types of commercial roof systems so that you can make the right choice for your business. Unlike residential roofing, commercial roofing has very specific requirements because commercial buildings are usually larger and taller. The roofing material you choose will determine the life of your building and the safety of the residents.

Low Slope Roofing

The roof you choose for your commercial property depends entirely on the degree of slope of the roof. Materials that work on low slope roofs are not always the best choice for high slope roofs. The following are options to consider for a low slope roof

Ethylene Propylene Diene Terpolymer Roofing (EPMD):

EPDM roofing is a type of rubber roofing made from a combination of ethylene and propylene. EPDM roofing is extremely versatile and is known for its durability. Moreover, EPDM is the longest lasting type of commercial roofing available on the market and can easily last up to 40 years with the right environmental conditions and routine maintenance. They are easy to maintain and repair, and have a simple clean look.

Thermoplastic Roofing (TPO):

TPO roof systems

are becoming extremely popular in commercial construction because of their cost effectiveness and functionality. TPO roofs are made from a durable material which stands up in high and low temperatures making them a good option for any climate. They are impervious to ultraviolet rays, chemical exposure, and the ozone as well as being resistant to punctures, fire, and damage from high winds. On average a TPO roof lasts over twenty years and can withstand even the harshest environments.

Polyvinyl Chloride Roofing (PVC):

PVC roofing

is similar to TPO roofing and is also an excellent choice for commercial properties. PVC roofing is created by using sheets of PVC that contain plasticizers and stabilizers. They are available with a fleece backing that helps insulate the building. Like TPO roofs there are extremely durable and can withstand a full range of temperatures. They can withstand damage from punctures, fire, ultraviolet rays, chemical exposure, and other harsh environmental factors. With a wide range of colours to choose from, they are a popular choice.

Built-Up Roof Membranes (BUR):

BUR

are commonly referred to as “tar and gravel roofs” and are one of the oldest styles of commercial roofing. This system is created through layering. Flat roofs can be single-ply or built-up using multiple layers of liquid tar or asphalt over tar/asphalt saturated paper; or have multiple layers of other types of waterproof membranes. This is topped with a layer of pea-size gravel to protect the tar from the elements. The lifespan of a BUR roof depends on the materials used and the thickness of the layers but they have been known to last up to 50 years.

Steep Slope Roofing

If you have a steep slope roof (greater than 4/12 pitch) on your property, you need a roofing material that works with your architecture. The following options should be considered when dealing with a high slope roof:

Roof Shingles:

Shingle roofs

are one of the oldest roofing systems and are still very common across North America. Shingles are a roof covering made up of individual overlapping sections laid in courses from the bottom edge of the roof up. Each successive course overlaps the joint below, creating a layered, water shedding system. Shingles are available in various materials such as asphalt, wood, tile, metal, plastic, fibre cement, and flagstone. The durability of your shingle roof will depend on the type of material you select.

Asphalt Shingles:

are a water shedding system, and a great option for high or steep sloped roofs. Asphalt shingle roofing starts with a layer of base material followed by a sturdy felted fabric upon which the shingles are layered. Depending on the type of asphalt shingles chosen they have warranties ranging from 20 years to a lifetime. This option is easy to maintain and offers a wide variety of colour options.

Cedar Shakes/Shingle:

Wood shingles and shakes

are a favoured roofing option due to their beautiful colouring, durability, and natural insulating properties. This differs from shakes, which are made by splitting pieces of wood from a bolt. Wood shingles and shakes come in a variety of distinctive patterns and materials. Cedar wood is a popular choice for shakes and shingles. Cedar can be expensive up front and requires regular maintenance. However, cedar roofs are durable, lasting up to 10 years longer than asphalt roofing, and are resistant to heavy rains, hail storms, snowstorms, and strong winds. They are also a natural insulator, making them an eco-friendly, energy efficient option.

Tile Roofing:

There are two types of tile roofing available for commercial applications: concrete and clay tile. Both concrete and clay tile are very attractive roofing options. Not only are they beautiful, they are incredibly durable, especially against environmental factors like high winds, dramatic temperature changes, the ozone and ultraviolet rays. Tile roofing can last 50 years with the right maintenance so they have a long-term cost benefit.

Metal Roofing:

There are three types of metal roofing available for steep slope applications: architectural metal panel, structural metal panel, and metal shingles. Metal roofing is a very good option in areas experiencing heavy rains or snow as they are designed to help direct precipitation off the roof. With minimal maintenance, a metal roof can last 60 years or more making it a cost-effective choice.

Synthetic Roofing:

is a catch-all term that describes manufactured products that replicate asphalt shingles, concrete tile, clay tile, metal panels, slate, wood shakes and wood shingles. Synthetic roof coverings contain recycled plastic and/or rubber as a key ingredient, making them significantly lighter than other roofing materials, and eco-friendly. They are mould, hail and fire resistant and can be less expensive than some of the other options. Depending on the type of synthetic roof you choose, they can last as long as 100 years.
