BUR Tar and Gravel Roof Repairs in Calgary

Flat Roofing Ltd offers built-up roofing systems in Alberta for low-slope and flat roofing membranes. The built-up roofing system is also referred to as tar-and-gravel roofing and is usually applied in three and four-ply thicknesses. This makes it different from other types of low-slope roofing systems that utilize single-ply membranes. The gravel used in the built-up roofing system secures the roofing material and helps in protecting the underlying layer of roofing materials. It also helps in extending the life of your roof by preventing cracking. If you’re facing issues with your existing BUR flat roof, call us for BUR tar and gravel roof repair services in Calgary.

Benefits of BUR Roofing
The built-up roofing system is made of alternating layers of asphalt and reinforcing materials which lend a smooth finish to the roof surface. As these roofs offer water resistance and high tensile strength, they are considered ideal for commercial and industrial roofing. It is due to these features that these roofs can also withstand harsh Canadian winters. A BUR tar-and-gravel roof keeps heat away from the underlying roof structure and provides UV protection. The gravel offers a good grip for foot traffic for maintenance or repairs and also prevents debris from flowing towards and clogging the drains.

Gravel on a Ballast Roof System
A different type of gravel, called ballast gravel, is used for single-ply roofing systems. The primary reason to use ballast in single-ply roofing systems is to weigh down the roofing materials. Roofers also use ballast gravel as it offers protective benefits like other BUR roofs.
Since single-ply roofing materials are not self-adhered, they need a material to secure the waterproofing membrane to the roofing materials underneath. Thus, ballast is used in such cases for weight to make the roof resistant to strong winds. Ballast is not like BUR protective gravel. The ballast stones are usually one to two inches thick to provide substantial protection against wind gusts.
You must be wondering why ballast is used if it offers similar results as BUR gravel. The answer is that the ballast system costs much less than the BUR tar and gravel system. It also requires less application time. It is a great choice for commercial buildings.
