If you’re in the market for a new roof, you may be doing your research on a number of roofing materials and roofing systems.
Keep reading to learn more about one of the common options – a built-up roofing system. We’ll cover the pros and cons and all the material details of a bur system, like modified bitumen, tar and gravel, and roof membranes.
What is a built-up roofing system?
This roofing system, also known as tar and gravel roofs, is made up of alternating layers. These layers include modified bitumen (asphalt) and other fabrics used for reinforcement. Once combined, the multiple layers of bitumen make up a complete membrane. Built-up roofs are best utilized on a low-slope or flat roof deck.
Built-up roofing is also known as BUR (Built-Up Roofing) for short.
How do you install built-up roofing?
When it comes to a BUR roof, installation for residential or commercial roofing follows the same process. The first part of the process is hiring a qualified roofing contractor familiar with bitumen roofs and installing BUR systems.
Your contractor will attach ply sheets (a ply sheet is often plywood) to the roof subsystem. They may also install a cover board, which helps create a better substrate for the membranes. The next step is a base sheet and adhesive. Depending on the situation, your contractor may elect to use cold-applied adhesive. The cold applied process can improve the roof’s water resistance.
From there, a final layer of hot asphalt is typically applied to the layers of bitumen that make up the BUR roof systems. The top layer (also referred to as cap sheet, or mineral surfaced cap) completes all the roofing material that goes into built up roof.
While it sounds complicated, these roofing materials are easy to install when done by a qualified professional and are popular in both residential and commercial roofing. They’ve been around for fifty years and offer low maintenance, reliable protection for up to twenty years when installed properly.
How thick is built-up roofing?
A BUR roof system comes in multiple layers, most often between two and four. The thickness depends on the materials used and the number of built-up roofing layers applied, but typically the selvage area ranges between two to four inches.
