Built-up roofing, also called BUR, is the most common roofing material used on low-slope roofs. It is composed of alternating layers of reinforcing fabric and bitumen (asphalt) and is finished with a top layer of aggregate, such as stone or gravel.
Most built-up roofing is comprised of three parts: bitumen material, ply sheets, and one or more surfacing materials. The bitumen can be either “hot,” meaning it is heated so that it liquefies during installation, or it can be “cold,” which is more like an adhesive and is not heated. Cold built-up roofing can be sprayed or applied with a squeegee. It does not give off toxic fumes during application and is not dependent on weather. It also offers better performance than hot built-up roofing.

Built-up roofing is nothing new. The concept been around for over 100 years, although the material and its installation certainly have evolved during that time. Modern built-up products incorporate a rigid insulation layer for improved energy efficiency. Depending on the climate and the specific materials used, built-up roofing has an average life expectancy of 15 to 30 years, but some constructions can last up to 40 years. To ensure proper roofing installation and maximum results, utilize the knowledge and skills of the expert team at Galvin Home Renovations.
Built-up roofs tend to provide excellent waterproofing and ultra-violet protection. Thanks to the aggregate top layer, they are also fire-resistant. Built-up roofing is generally low-maintenance and therefore costs little to maintain over its life.
