Flat Roofing

Bland Brothers Roofing has been offering flat roofing since we started. Originally, along with the rest of the industry, we used tar and gravel roofing. Since new technologies have evolved, we have switched to an IKO/CRC SBS (Styrene Butadiene Styrene) roofing system applied with a propane torch.

This type of roofing is an evolution of asphalt roofing. It is made from asphalt and a variety of modifiers and solvents with a polyester or fibreglass reinforcing mat. These are sandwiched between two layers of rubberized asphalt, with a finish coating of ceramic granules. These granules keep it cool and protect it from the UV rays of the sun.

This two-ply roof system is quite durable but more flexible because it will not crack or break (especially in colder weather like the old tar and gravel roofs). Repairs for tar and gravel roofs can be hard, mainly because it is difficult to locate the exact point of a leak. However, this new flat roofing system can be patched relatively easily and breaks & leaks are easier to locate. There is no longer any need for heavy gravel because this new SBS system is attached to the roof deck. There are several ways of connecting pieces of this material; we primarily use a heat application process where the seams are heated to melt the asphalt together and create a seal. (No foreign adhesives are used to adhere the pieces together. ) Occasionally, we use some self-adhesive forms of this system. Our workers have all the proper training for use of a propane torch.

In some cases, there needs to be some changes made to the framing of the roof, to help correct pooling and to ensure proper water drainage. This process is called resloping. Our estimator, who will come to your home, will let you know if this is an option for your roof.
