Torch on Roofs

Torch on roofs generally consists of 2 plies or layers of Modified Bitumen Membrane. Each layer, or pile, is approximately 3 to 4 mm thick. Its base ply is either attached to the substrate with adhesive or mechanically secured (using screws through large washers known as “plates”).

The cap sheet is much similar in composition, but most times have a granulated surface to offer protection from the elements. Both the bottom face of the cap sheet and the top surface of the base sheet features a thermo-fusible plastic surface. This means that they can be fused – or joined together – thermally, in this case using melting both surfaces using a propane torch.

The major boon of Torch on Roofs is its durability. These roofs are expected to have an average lifespan of 25 years, depending on the varying local conditions and installation practices. Low maintenance costs and resistance to UV rays are also selling points. In recent years, the costs of installing Torch On Roofing in Coquitlam have come down and its quality has gone up, meaning that it’s a cost-effective alternative for flat roofs.
