Modified Roofing for Local Businesses

A close-up image of modified roofing.Torch down roofing (Modified roofing) is a type of roofing material that has been designed for low-angle or flat roofs and has been the workhorse of commercial roofing for nearly five decades.

The product gets its name from the method of application used to install and adhere it to a building’s structure. The part of the material that makes contact with the decking underneath is melted with a torch in order to seal the material. This helps to provide a secure hold and creates a waterproof seal that can prevent unwanted leaks. If it is installed correctly, torch down roofing can last a very long time.

We have many modified roofs still in service long after the 10-year manufacturers warranty has expired, due to our skilled mechanics and proactive clients using periodic maintenance.
