Built-up roofing (BUR)

When thinking of doing a built-up roof, it's important to consider the quality of the materials being used as well as how experienced the contractor is. The professionals at Genesis Roofing & Contracting have serviced over 40,000 satisfied customers since 1974. We provide flat roofing installations and flat roof repairs in the Greater Toronto Area.

Mopped and/or torch down modified bitumen

Modified bitumen, sometimes referred to as rubber, is a waterproof sheet factory-made from asphalt and reinforced with a high-strength mesh. The sheets are applied by torching or by asphalt mopping the first sheet (base sheet), so that each sheet is sealed to the next and to the substrate.

The next layer is torched to the first layer in a similar manner. The final sheet (cap sheet) usually has granules similar to shingles, meant to stop the sun from removing the oils from the sheets. Although some contractors apply only one sheet, two or three sheets are recommended for durability.

If you're considering flat roofing for your Toronto home or business with a flat or low-sloped roof, torch down is used for both. Extra precaution must be taken while doing torch down — proper precaution ensures the membranes are well bonded, not overheated, and substantially reduces the risk of fire. Our roofers will walk you through the process and educate you before beginning a job so you understand your investment.

Peel and stick modified bitumen

Modified bitumen sheets are also available with an adhesive side, which can be installed on the substrate without torching. Subsequent layers are then torched to the peel-and-stick membrane.
