What is torch down roof installation?
If you’re unfamiliar with the phrase ‘torch down roof’, you’re not alone! Many property owners discover this roofing strategy for the first time when they begin researching roof repairs or new installations. Torch down roofing is a specific roofing method in which an open-flame propane torch is used to heat sheets of modified bitumen, enabling it to fuse with the surface of the roof in a waterproof seal. Bitumen is a compound made from asphalt and modified with either rubber or plastic. This enables the material to withstand varying temperatures because it can expand and contract without cracking.
A Message from Dr. Roof
Torch down roofing is a waterproof, durable, and weather-resistant material, but it isn’t for everyone! It’s best suited for low slope roofs with pitches between ¼: 12 to 1: 12. When applied to low-slope roofs, it will provide additional strength and resistance. On the other hand, if your roof is completely flat or filled with high slopes, we don’t recommend torch down roofing.

Torch Down Roof FAQs
Below, our expert roofers have answered your most frequently asked questions about torch down roofing! Check it out!
Torch down roofing is very popular because it is water-resistant and suitable for all climates. It is also extremely resistant to UV rays, which help maintain the energy-efficiency of the building. Torch down can even be the most economical option for property owners with low-slope roofs.
The biggest challenge of torch down roofing is that it is very difficult to install properly. In order to seal the material, roofing contractors have to use a high-temperature gas torch. Torch down roofing should only be applied by a contractor who has completed the Certified Roofing Torch Applicator (CERTA) program safety training, available through the National Roofing Contractors Association (NRCA).
While the membrane system that underlies torch down roofing is quite inexpensive, there are many other factors that will influence the cost. Labor costs are often higher than other roofing services because of the training, insurance and equipment costs involved.
Before it is applied to the surface of your roof, torch down roofing will arrive in the form of rolled sheets. Inside these sheets, you’ll find multiple membrane layers stacked together. All torch down roofing contains thermo-fusible film, modified bitumen, and reinforced polyester. Some torch down also has a granulated mineral surface, but this is not required.
Torch down roofs are durable and affordable, but they lack the longevity that you might find in tile roofing. On average, the life expectancy of a torch down roof is 15 years.
