Tar and gravel roofs, also known as built-up roofing or asphalt and gravel roofing protect and cover a majority of the buildings in the greater Montreal area with flat or nearly-flat roofs. Tar and gravel roofs are created by applying hot bitumen (the tar) between multiple layers of fiberglass-based asphalt sheeting.
The surface of the finished roof is coated with a top coat of bitumen and a layer of gravel. The primary purpose of the gravel is to protect the roofing material from the damaging effects of sunlight and abrasion. Sunlight and heat is also reflected by the light colored gravel.
The investment required for a built-up (tar and gravel) roof is minimal when evaluated over the life cycle and durability of the installation. Roofs can last between 10 and 20 years depending on maintenance and severity of the weather. Tar and gravel roofs have a great reputation with architects, building owners, engineers and roofing contractors.
