Torch Applied Modified Roofing Systems

A torch applied modified system can last 15 to 20 years, which, combined with its water and UV resistance, makes it a good choice for flat commercial roofs.

A torch applied modified system will cost on average between $3 and $6 per square foot. A torch applied modified system is labor intensive and the slope of the roof and its complexity can add to the cost of labor.

The torch applied modified roofing system has been commonly used for commercial buildings since the 1970s. Although it is effective at sealing out water, sometimes water can pool on a flat roof and cause problems. Applying the bitumen with a torch is a labor intensive process that can be dangerous and needs to be done by professionals. This roofing system also has a shorter lifespan than some other options for commercial buildings.

Torch applied modified roof systems require little maintenance if they are installed properly, but we do recommend regular inspections for any damage to the roof or areas where water could pool. A roof can also benefit from being resealed every five years to extend its life and maintain the waterproof seals.

Most solar companies will install solar panels on nearly any type of roofing. For membrane systems like torch applied modified systems, they use a ballasted rack approach where panels are placed on racks on the membrane and held down with ballasts so the waterproof membrane is not penetrated. Diversified Roofing does not install solar panels, but we are happy to perform a roof inspection to assess if your roofing system is ready for solar panels.

One of the best advantages of a torch applied modified system is its ability to withstand heat and UV rays. The bitumen based membrane is flexible, which gives it the ability to expand and contract during temperature shifts without cracking. The combination of bitumen and polymers gives the roof excellent UV resistance and helps lower the cost of energy bills as well.
