What is a Torch Down Roof?

Torch down roofing, also known as “torch on” roofing, is called so because it needs an open-flame propane torch. A roofing professional uses a hand-held propane torch to heat the material and attach it to the surface. Once the layers get the right temperature, seams are melted together to create a waterproof seal.

There are many advantages to torch-down roofing. The first feature of any roof system is to keep water out of the building, and torch-down roofing has excellent water-resistant properties. Provided the membrane and insulation are installed per the manufacturer’s application guidelines, the flat surface of a torch down roof prevents water from accumulating and allows it to drain off.

Advantages of Torch-Down Roof

• The cap sheet on a torch-down roofing system has resistance to UV rays and reflectivity to keep the building cool and energy-efficient.
• Torch-down is a rubberized material; it allows for excellent expansion and contraction in the intense heat and cold a roof can tolerate.
• Its flexibility keeps roofs from cracking and makes it a very effective low slope or flat roofing material.
