The Risks of Torch Roofing

Torch roofing, also called torch-on, is the process of applying a waterproof roof over a flat surface. Torch-on roofing systems are typically used on low-slope, flat or slightly-pitched roofs. The main benefit of this type of roof is its durable finish and ability to withstand wind, rain, and UV rays. It is suitable for residential buildings and can be installed on most types of roofs. However, before you decide on a torch-on roofing system for your home, you need to make sure you are aware of the risks associated with it.

The process of installing a torch-on roof involves melting the roofing materials with a torch. These include modified bitumen and waterproof resins. Modified bitumen is a common material for flat roofs. Unlike standard asphalt shingles, this material is waterproof and able to resist leaks due to standing water and ice. Aside from its durability and sturdiness, it is affordable as well.

If you want to install a torch-on roof, you will need a torch, a hammer, a drill, a spark igniter, and a ruler. Before you begin, you must remove any old roofing that may have fallen off. You should also take care to keep any flammable debris at least 10 feet away from the building.

Torch roofing is a great option for low-slope or flat roofs. Although it is easy to install, it is not recommended for pitched roofs. Its flexibility means that it can easily be re-installed after a storm. Depending on the Torch Roofing material used, it can last anywhere from twenty to forty years.

There are two types of torch-on roofing systems: two-layer systems and three-layer systems. Two-layer systems feature a sheet of fiberglass felt as the base for the roofing membrane. Small granules are added to the top of the membrane to add UV radiation protection.

Three-layer systems feature a sheet of granule cap sheet and a smooth sheet of insulated fiberglass. Both types require a separate POL connector for vapor and liquid withdrawal. For a vapor withdrawal system, the hose should be less than 33 feet long and rated at 125 psi. Using different hose types can be a safety risk.

Some people choose to have their existing roofs re-roofed with a torch-on system. It is important to note that you will need to get a fire extinguisher within 100 feet of the work area. This is because the torch can be very dangerous.

In addition to its durable finish, torch-on roofing offers excellent insulation. While the initial cost can be high, it is relatively affordable to maintain. Moreover, it can be repaired by professionals.

The materials required for torch-on roofing are cheap and can last for many years. However, because of its flexible nature and the risks involved, it is best to hire a professional contractor to install it. Insurance coverage for a roof installation is expensive, but most large-scale commercial roofing companies can afford it.

Torch-on roofs are easy to repair and maintain. Compared to other roof systems, they are inexpensive and require only reasonable maintenance.
