What is Modified Bitumen Roofing?

Modified bitumen is a modern version of the old built up roof system, but instead of many different layers of asphalt and fabric, it’s made up of a single membrane applied on top of insulation. The roofing membrane consists of an asphalt product called bitumen mixed with various plastics and additives and reinforced with polyester and fiberglass fabrics.

Why Choose Modified Bitumen for Your St. Louis Roof?

• Seamless Roof Protection – Because one layer is applied as a liquid and cures into a solid, the roofing is a complete layer of waterproof protection over a flat roof.
• Resistant to Sunlight – Modified bitumen roofs are highly heat resistant, and reflective coatings also make them UV ray resistant, which increases energy efficiency in the building.
• Weatherproof – The nature of a flat roof makes it wind resistant, but a modified bitumen roof is also completely waterproof and resistant to the physical damage caused by hail or debris.
• Easy Installation and Repairs – Because it’s made up of sheets, modified bitumen roofing can be easy to install, which keeps costs low, but that also makes it easy to repair.
