Modified Bitumen

HKC roofing specializes in the repair, restoration and maintenance of modified bitumen roof systems (torch-down roof). Modified bitumen roof systems are an evolution of asphalt roofing. It is made from asphalt and a variety of modifiers and solvents to produce a hybrid sheet with many enhanced characteristics.

There are several ways to apply modified bitumen sheets. In a heat application process the seams are heated to melt the asphalt together and create a seal. There is also a cold-applied adhesive application, and some self-adhesive forms of this system. This material is also referred to as APP or SBS. Modified bitumen roofs are extremely durable and have a long performance life when installed correctly. These roofs have many economical repair and maintenance solutions to extend the useful life of the system.
