What Is Torch Down Roofing?

Torch down roofing is a type of roofing made from layers of modified bitumen adhered to the roof surface with the application of heat. This method is most commonly used on flat or low-sloped roofs. The bitumen is modified with polymers to improve its elasticity and durability, which allows it to expand and contract without cracking under weather fluctuations.

The term “torch down” refers to the method of application used for this type of roofing. During installation, a propane torch is used to melt the asphalt side of the bitumen roll as it is rolled out onto the roof surface. This melting process allows the bitumen to bond securely to the roof, creating a continuous waterproof seal.

Torch down roofing is known for its durability and can typically last between 15 to 20 years if properly installed and maintained. The actual lifespan can vary based on factors like climate, roof design, and the quality of maintenance performed throughout the roof’s life.

Torch down roofing offers several advantages including excellent waterproofing capabilities, resistance to UV rays and harsh weather conditions, and minimal maintenance requirements. It is also resistant to tears and punctures, making it a robust choice for areas prone to extreme weather.

Torch down roofing materials are primarily derived from petroleum, which is not renewable. However, many manufacturers now produce low-VOC (volatile organic compound) versions to reduce environmental impact. Additionally, the durability of torch down roofing means less frequent replacement, which in turn reduces waste.

Torch down roofing is especially effective in both hot and cold climates due to its thermal stability and waterproof nature. It performs well in areas with significant rainfall and can withstand the thermal contraction and expansion typically seen in areas with high temperature fluctuations.

Torch down roofing requires relatively low maintenance. Routine checks should be performed to ensure there are no punctures, tears, or other damage. It’s also important to keep the roof free of debris and standing water to prevent any potential damage. Periodic professional inspections are recommended to maintain its integrity.

The initial cost of torch down roofing can be higher than some other roofing types due to the materials used and the skilled labor required for installation. However, considering its longevity and minimal maintenance costs, it can be a cost-effective solution over time.

Yes, one of the benefits of torch down roofing is that it can be relatively easily repaired if damaged. Small punctures or tears can be patched with a torch down membrane. Larger areas may require cutting out the damaged section and replacing it with a new membrane, which should be professionally done.

Compared to other flat roof options like EPDM (rubber roofing) or TPO (thermoplastic polyolefin), torch down roofing is often chosen for its superior durability and resistance to moisture. It is less susceptible to leaks than other flat roof types and can handle extreme weather conditions better, making it a preferred choice for many commercial applications.
