What Is Torch-on Roofing?
Torch-on roofing, also known as flat roofing, is the key to ensure a well-maintained and long-lasting flat roof. It is a unique process to facilitate the best seal and waterproof finish in flat and sloped roofs. An open-flame propane torch is used to seal your roof against the exterior elements. Here is how it works:
8
-
An asphalt compound called bitumen is used to seal the roof
-
The bitumen is modified by adding rubber or plastic to increase its strength
-
The rubber in bitumen makes it easy to expand and contract
-
The material is heated to the point that it melts
-
It offers high tolerance to heat, cold, and moisture
Torch-on roofing is an effective method to make your roof water and weather-resistant. You can also opt for two-layer roofing or three-layer roofing for added protection.
As flat roofs are likely to hold water from rain and snow for a more extended time than sloped roofs, there are chances of damage. In such cases, torch-on roofing offers the protection your roof needs.
Components of Torch-on Roofing Systems
-
Insulation: It helps to retain heat in the building/structure
-
Vapour barrier: Applied after insulation, this barrier helps in keeping a check on the condensation and moisture problems
-
Overlay board: An overlay board is used to support the torch-on membrane, which helps in preventing water pooling
-
Base sheet: It is the first layer of modified bitumen applied on the roof
-
Cap sheet: This sheet is applied as the top sheet of the torch-on roofing
-
Flashing for penetrations: A self-adhering modified bitumen membrane is the material typically used for flashings
