FLAT ROOFING SERVICES
At Passion Roofing, wea specialize in not only providing roofing for residential homes, but also for commercial and industrial businesses. Many businesses are built with a flat roof, which means it is important for a professional to regularly inspect and repair it due to the increased risk of piling snow and leaks. A built up roof or (bur) is an old roofing system that is still being used today for flat roofs. It is a roofing system that consists of multiple layers of paper felt, imbedded with asphalt, glued together with hot tar, and protected from the sun by a topping of gravel.
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 Passion Roofing have serviced more then 500 customr since 2002.
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 are 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 that the membranes are well bonded, not overheated and substantially reduce the risk of fire. At Passion Roofing, 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.
