Ottawa Flat Roof Installation and Repair
Especially used on flat roofs, the roof with membrane elastomer (modified bitumen) has been installed for more than 40 years. The product offers a double layer (bilayer) of membranes fused to each other. Consisting of a base membrane and a finishing membrane with granules, the membrane is very successful because it does not require much maintenance. The elastomer modified bitumen membranes provide a particularly uniform quality. The top layer is made of fine grains of ceramic which creates its color. Some experts insist that a properly secured, well-ventilated membrane will last up to 35 years, with minimal maintenance.

To do this you need to make sure that the gravel is in place to protect the membrane from the sun. The primary source of degradation of an asphalt and gravel roof is due to its exposure to sunlight. These create heat which dries the oils from the asphalt and fragile. By becoming more brittle, there is a high probability of cracks appearing in the membrane. If the gravel separates, it is recommended to sweep it, putting back liquid asphalt specially designed for repairs on a roof. Then, it is suggested to reposition the gravel.
