What are Common Causes of Commercial Roofing Problems?

What are Common Causes of Commercial Roofing Problems?

Having a durable commercial flat roof is a necessity for any commercial property owner in Toronto. And while commercial or industrial roofs are built to last, they can encounter a lot of enemies that put threat to their integrity.

So, what are these enemies? And what problems can they cause?

Here are the top four most common causes of commercial roofing problems. Some may be obvious, while others may surprise you.

  1. Extreme Weather Conditions

Extreme weather is arguably the most common cause of commercial roof damage. Heavy wind, rain or snow, as well as extreme heat or UV exposure, can pose a threat to any type of commercial or industrial flat roof resulting in blow offs, punctures, dents, leaks, swelling, etc. As a commercial property owner, it’s up to you to understand the types of preventative measures to take so that your flat roof can withstand the extreme or unpredictable weather patterns we often see in Southwestern Ontario.

  1. Lack of Maintenance & Inspections

Your commercial flat roof should never be neglected, and there are many reasons why. Not only will a neglected flat roof cause financial stress, it’s also extremely unsafe. If you own commercial property in Toronto, it’s important to have routine inspections performed on your flat roof. Pooling water, a base flashing that is loose, or pitch pockets that haven’t been filled can be easily spotted and fixed.

Additionally, commercial roofing damage may not always be visible with the naked eye. In this case, it’s important to consult a professional commercial or industrial roofing company to perform a more thorough inspection through infrared detection. An infrared roof survey is designed specially to detect flat roof damage not visible to the human eye, and could therefore provide an efficient way to identify specific problem areas on your commercial or industrial flat roof.

  1. Poor Installation

Faulty installation of a commercial roof will increase the likelihood of problems and will reduce the roofing system’s overall effectiveness. And while you’d never want to be the one to hire an unauthorized or inexperienced roofing contractor, faulty workmanship is one of the more common causes of commercial roofing problems.

As a commercial property owner, always ensure the roofing expert you hire is legitimate. Some simple steps to take in ensuring proper workmanship on your commercial or industrial flat roof are:

  • Ask your commercial roofing contractor for a checklist specific to the roof system that can be used for information gathering.
  • Ask about moisture/infrared surveys and general roofing inspections.
  • Have your contractor provide a written inspection report complete with digital photos. The contractor should also provide clear details on any structural changes or modifications to the roof surface.
  • Ensure the commercial roofing contractor you hire is fully licensed and insured within the local jurisdiction, and that they can provide legitimate documents upon request.
  1. Too Much Foot Traffic

Although regular roofing inspections are necessary to preserve the lifespan of your commercial or industrial flat roof, you should limit the amount of people that enter it. Too much foot traffic can lead to holes, punctures, or denting that can be of detriment a person’s safety and to your property as a whole. You should also avoid putting heavy or unnecessary equipment that can weigh the roof down.

What are The Most Common Types of Flat Roofs?

What are The Most Common Types of Flat Roofs?

When it comes to commercial flat roofs or industrial flat roofs, there are many things to know. With so much information out there, it’s important for property owners to familiarize themselves with the types of commercial or industrial flat roofs available on the market today. It’s also important to know which are common and best suited for their property and its specific needs.

If you own commercial or industrial property in the Greater Toronto Area, and are looking for flat roof repairs or a complete flat roof replacement, you’ll want to know what the most common types of flat roofs available are. Why? So that you can choose the best-suited flat roof for your property.

Let’s take a look at four of the most common types of flat roofs available for commercial or industrial properties in Toronto.

  1. Built-Up Roof (BUR)

Built-Up Roofing is a traditional type of flat roof that is made from hot tar, asphalt and gravel. The roof itself is built from layers of waterproof material alternated with hot tar and ballasted by a layer of gravel. The result provides a long lasting, highly durable waterproof membrane to give your commercial or industrial flat roof years of quality service.

BUR roofing is arguably the most common type of commercial or industrial flat roof available today. In particular, this durable and water-resistant flat roof performs exceptionally well in tough Canadian winters, and more specifically, during Toronto’s wet, drizzly springs.

  1. EPDM (Rubber Membrane)

Ethylene Propylene Diene Monomer (EPDM) is another common type of flat roof for commercial or industrial buildings. EPDM roofs are made from a synthetic rubber created from a combination of ethylene propylene and diene, resulting in a highly flexible, yet durable flat roof.

EPDM roofing is common option today because it’s not only easy to maintain, but it’s also engineered to withstand damage from sunlight (a great option for commercial or industrial buildings in warmer climates). EPDM rubber membrane is a popular option for low-slope buildings, but can accommodate various building designs and structures.

  1. Modified Bitumen

Modified Bitumen is a common type of flat roof designed for flat and low-sloped buildings. Flat roofs made from modified bitumen roofing are composed of polymer modified bitumen material and reinforced with one or more layers of fabric. This type of commercial or industrial flat roof can be installed with a variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied.

There are two types of modified bitumen membrane used for commercial flat roofs or industrial flat roofs. They are:

(1) Atactic Polypropylene (APP): APP is made up of a thermoplastic polymer and is usually applied using a propane-fuelled torch.

(2) Styrene Butadiene Styrene (SBS): Gives commercial flat roofs or industrial flat roofs a rubber-like appearance. SBS roofs are very durable and highly withstanding to harsh winter weather. This type of roofing system is most commonly installed by heat welding, or cold application.

  1. PVC or TPO

PVC (polyvinyl chloride) or TPO (thermoplastic polyolefin) roofing are two commercial or industrial flat roof options that are single layered and made from material that is either white or gray. PVC or TPO roofing membranes can be adhered, similar to an EPDM rubber roof, or mechanically attached with screws and plates.

Both PVC and TPO roofs are becoming increasingly popular options for commercial or industrial flat roofing because of the environmental benefits. For example, PVC and TPO roofs are both made up of highly reflective materials that can reduce energy demand as well as monthly heating (with insulation) and cooling costs. Additionally, the vinyl used in PVC roofs can be recycled into new products, even after decades of use.

Preparing Your Flat Roof for the Fall

Preparing Your Flat Roof for the Fall

Throughout Canada, fall and winter signal the start of colder temperatures and increased precipitation in the form of rain, hail, or snow. These weather changes will have you thinking more seriously about your flat roof, and how you should be preparing it for the cooler months ahead. Failure to prepare your commercial flat roof for the fall and winter months could result in extensive (and costly) damage to both your flat roof and your property altogether.

As a way of avoiding major flat roof damage this fall, we’ve prepared some useful tips for flat roof maintenance in the fall and winter months. Read below to discover how you can prepare your commercial flat roof for the upcoming autumn season.

  1. Clean Your Flat Roof

Although flat roof maintenance and seasonal flat roof cleaning of debris should be completed throughout the year, it’s especially important before the colder temperatures arrive. During the fall, hiring a professional roofing company to clear off leaves, twigs and other debris from the roof’s surface and gutters is extremely important. Making sure that your flat roof is clean and free from seasonal debris before the first snowfall hits is vital. Failure to do so could result in severe punctures to the flat roof’s membrane, bringing forth leaks and other water damage caused by excess snowmelt.

  1. Inspect Your Flat Roof

Seasonal flat roofing inspections are a must for commercial flat roof owners. When it comes to commercial flat roofs, seasonal inspections are best left in the hands of a licensed professional. During flat roof inspections, a professional roofing contractor will look for loose or open seams, gaps, holes, and cracked or rusted flashings. If your flat roof experiences any of these signs of wear and tear, it’s important to take care of them before the colder months commence. If left untreated, freezing cold temperatures, snow, and ice could make these problems worse and maintenance more difficult.

  1. Ensure Your Flat Roof Drainage is Working Properly

Once a commercial roofing professional has cleaned and inspected your flat roof, ensure they pay extra attention to any drain hubs or other drainage areas around your flat roof. Not only should your flat roof’s drains be completely clear of seasonal debris, but they should also be tested to see if they are working properly. If your roof’s drainage system has any clogs or leaks going into the fall and winter season, then your roof is at higher risk for severe ice accumulation, which can result in extensive damage that may require a full flat roof replacement.

Commercial Flat Roof Types For Durability and Lifespan

Commercial Flat Roof Types For Durability and Lifespan

Among the many styles of roofs that Toronto commercial property owners have, flat roofs are the most common. One of the reasons flat roofing systems are so popular is that they are the most durable option for commercial and industrial buildings. Flat roofs also provide enough structure to house solar panels or HVAC equipment, and provide enough stability for foot traffic.

Are you looking for a new flat roof for your commercial or industrial property? Before moving forward in your search, it’s important to know which flat roofs are best suited for your property and which are most durable. Then, you can proceed with hiring a professional commercial roofing contractor in Toronto to install your new flat roof.

Below, you’ll find information on the best commercial flat roofs for durability and lifespan. This will help you evaluate each flat roofing option, so that you can make the best possible decision for your property.

  1. PVC (Polyvinyl Chloride)

PVC, otherwise known as polyvinyl chloride, is the third-most widely produced synthetic plastic polymer in the world. In fact, it’s among the most popular roofing system used for industrial flat roofs in the Greater Toronto Area. A PVC roofing system is a highly durable, long-lasting option that has a lifespan of 25-30 years.

Additionally, the sheets installed on a PVC roof are an attractive option for property owners looking for sufficient waterproof performance and ample foot traffic ability. Another additive is that because PVC is composed of highly reflective material, it can drastically reduce energy demand, and therefore, lower heating and cooling costs altogether.

  1. BUR (Built-Up Roof)

The built-up flat roof system is comprised of layers of waterproof membranes, tar, asphalt and gravel to seal the roof surface. This type of flat roof is a great option for a commercial or industrial building in the Greater Toronto Area. Not only is it an affordable option, its resistance to fire and harsh weather also makes it a great safety factor for a multi-person property.

When it comes to longevity, built-up roofs can last anywhere from 15-20 years if installed and maintained properly by a professional commercial roofing company. During installation, your property must be empty and free of tenants in order to do the job as quickly and efficiently as possible. Once installed, this durable and water-resistant flat roofing system will prove its effectiveness time and time again – even during the tough winters Toronto endures.

  1. EPDM Roofing

EPDM is a flat roof option that’s made of synthetic rubber and other recycled material. EPDM flat roofs are among the most durable and most inexpensive options for your commercial or industrial property. EPDM roofs have a longer-than-normal lifespan; they can be expected to last anywhere from 25-30 years or greater. An EPDM synthetic rubber roofing system is also highly resistant to weathering effects of ozone and ultraviolet light, making it a popular option for commercial and industrial property owners in warmer climates.

  1. Modified Bitumen

Modified Bitumen is another type of material used for flat roofs. It is a single ply roofing system that is applied by rolling the material onto the roof surface. A modified bitumen roof is also known for its effectiveness in extreme weather conditions i.e. weather climates, like Toronto, that have high winds, hail and heat. This durable, long-lasting roofing system can last at least 20 years when properly installed by a professional commercial roofing contractor.

As an owner of commercial or industrial property in Toronto, you know how important your roof can be. That’s why when it comes to installing a new roof, or replacing an old one, it can be overwhelming when deciding on which type of commercial roofing material to choose. Should you go with the existing material your current roof is made of? Or, should you replace it with a more suitable material for the specific needs of your property?

Before deciding on what material is best for your commercial roof, it’s important to do some research to help pinpoint the right option for you. So, let’s take a look at the most common materials for commercial and industrial roofing in Toronto, Ontario.

  1. TPO Roofing
    Thermoplastic polyolefin (TPO) is a newer type of roofing material that has become a very popular option, especially among commercial building owners in Toronto and the surroundings. TPO uses single-ply membranes, designed to resist damage from UV light and other chemicals. TPO is also a very energy efficient roofing material; it reflects sunlight, significantly lowering energy costs. The general lifespan of a TPO roofing system is 15-20 years.

PVC roofing systems can last anywhere between 20-30 years if properly looked after.

PVC roofing is also a very functional type of material, making it ideal for commercial or industrial properties in Toronto.

This saves money and extra manned hours simply because costly roof tear-offs wouldn’t be required.

PCV roofing works best for buildings that are either flat or low-sloped. And because PVC is excellent at holding up to extreme moisture, it’s a popular choice for people who own commercial property in wet climates.

  1. Metal Roofing
    Compared to the commercial roofing materials mentioned above, metal is a more durable and longer-lasting option for commercial flat roofs. Generally, metal roofs are made from copper, aluminum or steel. Steel roofing material is the most common because it’s harder and less prone to denting than aluminum or copper.

Is metal roofing right for my commercial property in Toronto?

A metal roof for a commercial or industrial building should last the entirety of its lifespan, which is anywhere from 50+ years if installed correctly by a professional commercial roofing contractor. Metal roofing can be an extremely viable option for your commercial property in Toronto, so as long as you properly maintain it. Because metal is prone to denting or rusting, seasonal routine inspections are a top priority.

How Long Does Your Type of Commercial Building Roof Typically Last?

How Long Does Your Type of Commercial Building Roof Typically Last?

The lifespan of your commercial flat roof in Toronto can vary drastically and depend on several factors. For starters, the type of roofing system installed and the quality of workmanship will largely impact the durability of your flat roof and how long it will last. In addition, there are other factors to consider when knowing how long your commercial or industrial flat roof will last. Not only will the type of roof you install matter, but the care you take in preserving its lifespan will too.

When it comes to commercial flat roofs in Toronto, there are some things you should know. A flat roof, for example, will not offer as much drainage as traditional pitched roofs. This means that water can become trapped in any holes or seams in the roofing membrane and decrease its lifespan if not taken care of. So, if you’re not adamant on commercial roof maintenance, the materials used to make your commercial roof were of low quality, or if the original contractor did not properly seal all parts of the roof, then its overall lifespan will become negatively affected.

Types of Commercial Roofing Systems in Toronto 

There are several types of flat roofs that a commercial or industrial building might have. Each one has a slightly different lifespan, installation process, materials, and cost. So, which is best for your property?

Let’s take a look at these different commercial roofing system types and how long they typically last. 

  1. Built Up Roofing Systems 

Built Up Roofs (BUR) are hot asphalt-based, multi-ply systems that are ideal for both sectional and complete flat roof replacements and repairs.

Durable and water-resistant, BUR roofing has been sealing and protecting flat roofs for almost 200 years. This type of commercial roofing system typically lasts anywhere from 20 to 30 years when installed and maintained properly.

  1. EPDM Roofing Systems

Ethylene Propylene Diene Monomer (EPDM) is comprised of synthetic industrial grade rubber that comes from a combination of ethylene propylene and diene. EPDM roofs are known to provide a longer-than-normal lifespan thanks to its highly flexible, yet durable membrane.

How long does EPDM roofing typically last?

EPDM rubber roofing can last anywhere from 20 to 30 years. This type of roofing can be applied in three thicknesses: 45 Mil (thousandths of inch), 60 Mil and 90 Mil.

  1. PVC Roofing Systems

Polyvinyl Chloride Roofing (PVC) is a type of single-ply roofing membrane that is generally seen on flat or low-sloped building structures. PVC is highly reflective and contains life-extending components such as cool roof pigments, UV stabilizers, and other materials to increase durability. This type of roofing system is also very cost-effective, making it suitable for flat roof repairs.

How long does TPO Roofing typically last?

While not as flexible as traditional PVC, TPO is less expensive and can generally last anywhere between 15 to 20 years. TPO is a great a cost-effective, yet very dependable alternative for most commercial or industrial flat roofs in Toronto.
