What is torch on roofing?
Torch on roofing is similar to tar and gravel roofing; however, there is no gravel, so they are lighter. Without getting overly technical about the chemical compounds involved, Torch On Roofing generally consists of two plies of Modified Bitumen Membrane. Each ply, or layer, is approximately 3 – 4 mm. thick. Both the top surface of the base sheet and the bottom face of the sheet have a thermofusible plastic surface (meaning they can be joined together thermally, in this case by melting both surfaces with a propane torch). Thus the term “Torch On Roofing”. The roofing material is rolled on and welded together permanently, forming a bond with the layer or layers underneath. Unlike tar and gravel roofing, there are no noxious or unpleasant fumes during the installation process.
The result is a strong and attractive roof that is extremely weather resistant and provides superior waterproofing for more than 20 years. Resistance to UV rays and low maintenance costs are also selling points. In recent years, costs have come down and quality has gone up, meaning that Torch On Roofing is a cost-effective option for flat or low-sloped roofs. You and your family will be well-protected from the outside elements. By sealing in heat and keeping moisture out, you will reduce your energy costs and increase the value of your home.
