Expert SBS roof install in Edmonton by MD Roofing - commercial roof contractor at work


The most common torch-on roof system that we install is the SBS Modified Bitumen Roofing Systems – This type of roofing is an evolution of asphalt roofing. It is made from asphalt and a variety of modifiers and solvents. There are several ways of connecting pieces of this material. In a heat application process the seams are heated to melt the asphalt together and create a seal. There is also a cold-applied adhesive application process, and some self-adhesive forms of this system. This material is also referred to as SBS. We only use the torch-on method as it provides the highest level of quality.

Manufacturing Method:
Modifiers are added to standard roofing asphalt to replace plasticizers removed during the distillation process. Bitumen is reinforced with fiberglass or polyester fiber matting in order to increase durability and strength. SBS (styrene-butadiene-styrene) modified bitumen increases the flexibility of the membrane and allows it to have stronger expansion and contraction capabilities.

Application Method:
Modified bitumen roof systems can be installed with the common torch method, asphalts, or cold adhesives. A standard SBS modified bitumen roof system is a two-ply system applied in rolls that overlap the edge of the previous roll.  We do not recommend using the cold application process.
