An effective roofing solution proven by over a century of history, a Built-Up Roofing System from Exterior Design & Development is one of the top choices for Commercial properties.
Built-Up Roofing Systems (or “BUR”) have been installed on buildings in the US for over 100 years. They are composed of a highly water-resistant membrane that is fabricated with layers of bitumen, alternated with reinforcing felts. The bitumen typically used in Built-Up systems is asphalt, coal tar, or a cold-applied adhesive. There are many options for Built-Up roof surfacings that include aggregate (such as gravel, slag, or mineral granules) as well as glass-fiber or mineral surfaced cap sheets. Other options are hot asphalt, aluminum, or elastomeric coatings.
The Advantages of a Built Up Roof
- Multiple layers of bitumen provide redundancy of protection that is sound and durable.
- Surfacing materials can be coated with a paint solution or other reflective materials to reduce effects of UV rays. These types of coatings provide the additional benefit of reducing heating and cooling costs for the property owner.
- Known for being easy to repair should the roof be damaged by a storm or other unexpected conditions.
- The ability to withstand strong foot traffic due to the durable materials used to construct built-up roofs.
