How can we help you

Flat roof inspection

Getting your roof inspected at least once a year is vital to maintaining the quality of your roof. One of our roofing experts will examine your business’s roof for signs of wear and tear or damage, then schedule a time to fix any issues before they become major problems.

Flat roof maintenance

Roofs need regular maintenance, just like the equipment found in your business. Missing shingles, leaks, or holes may result in expensive issues down the road. We offer premium commercial flat roof maintenance services that will keep your roof in tip-top shape.

Flat roof replacement

Every roof needs to be replaced eventually, but flat roof replacement doesn’t need to be a big ordeal. We’ll replace your commercial roofing in as little as one day, and we always make sure your business can carry on as usual during the process.

Roof leak repair

Commercial roof leaks are often frustrating, especially when they occur in areas that are seen by your customers or clients. Our team offers quick and easy roof leak repair services in the Greater Toronto Area and can arrive at a time that is convenient for you.

Proper Maintenance and Repair of Commercial Roofing in Markham

Commercial roof damage can be tricky. What looks like a simple leak could really be a rotting mess in disguise. For this reason, we recommend regular maintenance appointments to keep up with small problems before they turn disastrous.

While it may be tempting to fix a small leak with a DIY patch job, the potential for problems greatly outweighs any money you might have saved. In the end, a mistake with a cheap DIY kit could end up costing you big if you have to replace the whole roof. Even if it seems like a simple fix, unless you have professional roofing experience, it’s best to call in our team of professionals.

Our team members will complete a full inspection of your roof and provide you with a free estimate of any needed repair costs. We’ll never attempt to hard-sell you on a replacement if you don’t need one. Unless your roof is past its expected lifespan or has extensive wind or water damage, you may be able to hold off your roof’s demise with professional repair.

Commercial Roof Replacement

Sometimes a roof is beyond repair. Severe leaks or storms can ravage your roof and the structure beneath it. In these instances, a replacement might be necessary.

Your first step is to check with your insurance company and see if your policy covers a new roof. Then reach out to our Quality Roofers team to discuss your options. We’ll help you choose the right replacement to fit the needs of your building and your wallet.

Installing commercial roofing for a Markham, Ontario property is a huge investment. Not only are you paying for a new roof and future repairs, but business slows down until the project is finished. It’s important to choose a lasting roofing material and hire our reputable contractors to complete an efficient, quality installation so you can get back to business.

Types of Commercial Roofing in Markham

Each type of commercial roofing has its own lifespan and advantages. The number of choices may seem overwhelming, but you really only need to understand a few of the most popular. These include:

  • Green Roofing – a sustainable option offering protection from the elements and unique drainage techniques. Good for any commercial property owner looking to reduce their carbon footprint.
  • Thermoplastic Roof Membrane (TPO) – a roofing system using strong, reflective material to protect against weather damage, UV light, tearing, and organic materials. A great choice for restaurants due to oil and fat resistance.
  • Thermoset Roof Membrane (EPDM Roofing) – a durable system offering easy installation and minimal maintenance. Made of single-ply rubber, it’s resistant to UV light, ozone, alcohol, solvents, and acids. It also remains flexible in cold weather.
  • Modified Bitumen – a stable 2-ply system applied in layers with increased tensile strength. It requires minimal maintenance and is ideal for commercial roofs with a lot of foot traffic.
  • Metal – popular for its large range of material options, metal roofing prevents environmental damage with its layers of protective coating. It’s strong, durable, and fire-resistant as well.
  • Built-Up Roofing Membrane (BUR) – a standard system using layers of tar and gravel. The layers can be adjusted for durability and cost-effectiveness. BUR is a low-slope roofing system.

    The Difference Between Flat and Sloped Commercial Roofing in Markham

    Unlike the steeply pitched roofs of residential properties, commercial roofs usually use flat or low-slope designs. Flat roofs, as their name points out, are almost completely flat, while a low-slope roof is built with a slight rise. Each has its own benefits.

    Flat roofs often use the same materials as a low-slope roof but have a smaller surface area. This makes them cheap to install, maintain, and repair. The flat surface also allows easy installation of solar panels and HVAC components.

    While flat roofing systems are a low-cost option, their lack of incline can cause some issues. Poor drainage sometimes leads to standing puddles and water damage. The cost of recurring cleanup should be weighed against the potential savings.

    Low-slope roofs rise approximately 3 inches per foot, providing a smaller surface area than a steep residential roof. This makes them cheaper and easier to repair. Their slight pitch provides better water drainage than a flat roof system.

    Installing necessary items like vents and air conditioners on a low-slope roof is relatively simple. The severity of our northern winter, however, could cause problems. After storms, remove ice and snow so the weight doesn’t damage your building.

    Both low-slope and flat roofing use single-ply systems. Either can be made more energy-efficient by using light colored materials to reflect sunlight.


    How do I choose an appropriate roofing system for my property?

    After considering cost, your roofing choice will come down to your individual business needs. If your property houses a factory or warehouse, installing a durable roof to protect your equipment and inventory is much more important than aesthetics. If your business directly interacts with the public, however, you should install a roofing system that matches looks with durability.

    Our team of contractors offers expert advice on roofing systems and materials for industrial and commercial properties. Schedule an appointment to discuss your property and its individual needs.

    How is commercial roofing in Markham different than residential roofing?

    The biggest difference between residential and commercial roofing is how they handle water or hail damage. Water drains more easily from a steep-pitched roof, so there’s less of a chance of standing water for residential properties. Any damage that occurs can likely be fixed up with a quick patch or a few new tiles.

    Commercial roofs, on the other hand, have a higher chance of water damage. Regular maintenance and repair are the key to a long-lasting commercial property roof. Our Quality Roofers can re-seal or re-apply coatings to your roof for better protection.

    How long is the installation process?

    Commercial roofing installation is more complicated than residential. Glue and other materials need time to dry, settle, or cure between layers. Commercial systems might take over a month to complete.

    The actual installation time depends on a variety of factors. Replacement roofs may take less time than new installations. Likewise, weather conditions, roofing material, and property size also affect the length of the project.
