Built-up roofing (BUR) has been around for more than 100 years and remains one of the most popular commercial roofing options today. In this post, trusted roofing contractor Mass-Tech Roofing and Building Co. shares key information about BUR and why you should consider it for your property.
What Is a BUR Membrane?
BUR membranes are typically composed of alternating layers of bitumen and reinforcing fabrics called roofing felts or ply sheets. These two main components form the finished membrane, with the final layer consisting of gravel or crushed rock. Hence, BUR is also sometimes referred to as “tar and gravel.”
On average, BUR has a life expectancy of 15 to 30 years, depending on the climate in your region and the specific materials used in constructing your roof system. Generally, BURs perform better in warmer climates. In some cases, they can even last up to 40 years. This type of roof system is definitely reliable and long-lasting; that’s why many roofing companies confidently vouch for its durability.
Pros and Cons of BUR
BUR is widely known for offering excellent waterproofing, UV protection and fire resistance. In addition, BURs do not require a lot of upkeep, so you can expect minimal expense and hassle when it comes to maintenance.
A potential downside is that the installation process for BUR is complex. The process is typically slow, and hazardous fumes are created during the installation. BUR installation requires an experienced and skilled professional to ensure safety and correct application.
