Houston Modified Bitumen Roofing can offer an excellent solution and good protection for flat or low-angle roofs for residential and commercial buildings. Modbit, as some call it, uses modified rubber or plastics with added polymer compounds to make it rubber or plastic like. Added fiberglass, polyester or other fibers add insulating properties. Rolls are typically available up to 39 inches wide.

Introduced in the 1970s to the United States, the roofing method is applied in one- to three-ply and often require a gas torch to apply the systems. The heat of the torch seals the seams together, allowing the system to become waterproof. Modified bitumen is fast becoming the go-to method for roofing flat surfaces as its strength and durability are well known, according to recent roofing industry reports. Modbit roofs can have a useful life of 20 years or more partly because the roofing system is very strong when applied properly.
