Why Choose Flat Roof Systems?


A flat roof system is a popular choice for many people. This type of roof possesses many practical benefits:

Minimum cost

Lasting aesthetic look

Easy maintenance




Here are some of the flat roof systems you can choose from:


  • TPO roof systems: The most commonly used single-ply roofing system in the commercial sector, TPO membranes either adhere mechanically to the flat roofing system or are ballasted. TPO roof forms an insulated coating over your flat roof and protects it. TPO, also known as Thermoplastic Polyolefin, is made of a synthetic component. A fabric-reinforcing scrim is used to strengthen the membrane further. It is a great choice for anyone looking to save on energy costs in Barrie, Orillia, Newmarket or surrounding areas. 

  • PVC roof systems: It is the most popular commercial flat roofing system available today! It is a cost-effective solution with distinct characteristics. PVC flat roofing systems are remarkably durable and highly resistant to fire, chemicals, and strong winds. To create a flat PVC surface, a layer of polyester is sandwiched between the two layers of material. The roof is then coated with acrylic, which makes it more reflective and resistant to dust and dirt.

  • EPDM roof systems: This flat roofing system is widely used worldwide for low-slope buildings. Primarily made with ethylene and propylene, EPDM is either fully adhered to the flat roof or sealed to the roof with liquid adhesives. It is also known as a rubber roof and is available in various widths. It is a lightweight roof system that is easy to install and requires minimum repair. 

  • 2-ply modified bitumen roof systems: Asphalt-based flat roofing system is designed to withstand harsh weather. Popular in the United States and Canada, the 2-ply modified bitumen roof system can last up to 30 years if maintained properly. This roofing system is viscoelastic, durable, and resistant to moisture. If you are looking for a roofing system in Barrie, Orillia or Newmarket that works best with heavy foot traffic, the 2-ply modified bitumen roof system is for you! It is easy to work with and would be perfect if you must re-roof a tight space.

  • 4-ply built-up asphalt and gravel roof systems: As the name suggests, the 4-ply built-up asphalt and gravel roofing system is prepared by combining four layers of felt with a flood coat of bitumen and embedded pea gravel. This helps create a strong protective roof membrane for your commercial structure in Barrie, Orillia or Newmarket. If installed by professional roofers, the flat roofing system can last at least 20 years without maintenance. The roofing system is waterproof and puncture-resistant.

  • Below- and above-ground waterproofing systems: Proper waterproofing of below- and above-ground structures can save you from expensive repairs in the future. Moisture is your biggest enemy when it comes to longevity structures. Everything needs waterproofing, be it the foundation wall of your building, the tunnel, or the parkade slab. Sky High Roofing & Sheet Metal Inc. provides some tried-and-tested methods for your waterproofing needs. Whether you want to waterproof your green or commercial sloped roof, we have the right solution!

Understanding Flat Roofs on Commercial Buildings


Recognizing that “flat” commercial roofs aren’t entirely level is essential. They’re designed with a subtle incline, up to 12 degrees, towards the center or edges to facilitate proper drainage. Commercial buildings typically use flat roofs. Here's why:


  • Ease of installation: Installing flat roofs on expansive commercial edifices is more straightforward and safer than the complexities involved with pitched roofs.

  • Space for HVAC systems: Large HVAC units are conveniently placed on flat roofs, freeing up interior space for operational needs and reducing noise and vandalism risks.

  • Simplicity over aesthetics: The design of commercial buildings with flat roofs often prioritizes function over form, leading to savings on decorative elements. 

  • Energy efficiency: Flat roofs can be covered with reflective materials that minimize UV damage and heat absorption, leading to cooler interiors and lower energy costs.

  • Eco-friendly options: Flat roofs can support green spaces with environmental benefits like UV absorption and water management.

  • No need for gutters: The absence of gutters on flat roofs translates to reduced maintenance efforts and costs.

  • Water management: Commercial flat roofs employ efficient rainwater roll-off systems instead of gutters to prevent clogging and facilitate water redistribution.

  • Maintenance advantages: Flat roofs are more accessible for inspections and upkeep, making them practical for commercial use.

  • Durability: Materials like asphalt, EPDM, PVC, and TPO make flat roofs a long-lasting and budget-friendly option for commercial buildings.



Like most things, routine maintenance is the key to getting the most out of your flat roof. It can help you elongate the life of your flat roof's structures and keep roofing damage at bay. We recommend the following tips:


  • Inspections: You should enlist professional roofing contractors like us to inspect your roof thoroughly at least twice a year. We will identify any early signs of damage and nip them in the bud. 

  • Cleaning: Keeping your roof clean and removing debris is essential to avoid water accumulation and clogged drains. You should remove any leaves, dirt, branches and debris from your roof.

  • Clear ponding water: If you notice water pooling on your roof, you must take action. Failure to do so can cause moisture damage to your flat roof. 

  • Maintain flashings: Flashings create a protective barrier around chimneys, vents, skylights, and other structures. We recommend checking flashings regularly for signs of water intrusion. 

  • Fix leaks: Water leakage can occur in your roof due to accidental damage or wear and tear. You must address the leak immediately to prevent it from becoming worse. 

  • Snow removal: Excessive snow can strain the roof's structure with its weight and cause water damage. You can schedule our professional snow removal services during the winter months.
