    We Are Your Flat Roof Specialist

    Flat roof repair and installation requires a specialized approach compared to pitched roofs. If you need a flat roof installed or repaired, you need a team that has experience working with these different roofing systems.

    For instance, flat roofs are unable to displace water as easily as sloped roofs. To account for this, you’ll need alternative solutions like scuppers, roof drains, or a drip edge detail.

    And due to water being more prone to pooling on your flat roof, ensuring that your roof is waterproof is an absolute necessity, otherwise the water will permeate your roof and begin to damage the interior. 

    As a flat roofing specialist, you can ensure that we won’t overlook any details that less experienced commercial roofers in Toronto may miss.

    Two Ply Roofing Systems

    Two ply roofing systems are systems that use two layers of a modified bitumen membrane to protect your building. They are generally secured to a protection board that is on top of the deck.

    The revolution in two ply systems now is the self adhering membrane. It allows installers to use limited heat in order to adhere the roofing products. This adds extra protection in high risk areas such as walls and doorways.

    Flat Roofing TorontoThey offer two ply systems for all different types of decks. For example, on concrete decks, or old wooden structures, you can ‘mop’ or use hot asphalt to adhere the base layer to the deck. 

    You can then apply a torch applied cap sheet (top layer). Thus reducing the weight of the roof versus standard asphalt 4 ply systems and allowing for potentially easier repairs and replacements in the future.

    Four Ply Roofing Systems

    Four ply roofing systems consist of four layers of felt paper, with each layer sealed using hot asphalt. They are run continuously in an overlapping manner. They are then covered with gravel to reflect the sun and prevent deterioration.
