Asphalt and gravel roof in Montreal
A “multilayer” (asphalt and gravel roof) membranes consist of asphalt and crushed stone!
The tar is no longer used since the 70’s, because of the risks and its toxicity. The liquid asphalt has replaced the tar and the type of asphalt used will depend on the slope of the roof. Roofing asphalt and gravel is a multilayer covering method, consisting of 4 to 5-ply black paper, attached with hot asphalt. It must then be covered with about 4 pounds per square foot of crushed rock. This process is used primarily to restrict the wear caused by the sun’s rays and to mitigate the contraction of the asphalt when there are large temperature variations.
