SBS Modified Bitumen Roofing
Commercial roofing in Edmonton requires it’s own special roofing material needs. Commercial roofs tend to be flat roofs, meaning that their slope is less than 2%, giving the roof the appearance of being flat (although there is an angle to allow the roof to shed rainwater).
One popular type of flat roof that can effectively serve most types of commercial buildings is the torch on/modified bitumen roof. Here at Iron Shield Roofing, we offer SBS torch applied modified bitumen roofing installation in Edmonton and Alberta. Let’s go over this commercial roofing material and some of the benefits you can reap from it.
What is SBS Modified Bitumen
Modified Bitumen – Is a type of membrane roofing material commonly used for buildings that feature a low sloped roof pitch in Canada. The material is based on the same materials used in asphalt shingles; an fiberglass mat, saturated with SBS modified bitumen asphalt, and faced with granular stone aggregate. The installation process, known as Torch On Roofing, is often used on commercial properties in Edmonton and Northern Alberta
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 hot-mopped application, similar to how conventional built-up roofs are installed. Cold-applied adhesives and self-adhesive membranes are two of the more recent options.
Benefits of Modified Bitumen
The nature of modified bitumen’s mixture of synthetic rubber polymers and asphalt makes for a very flexible roofing solution. You can expect the following from this material:
- Modified bitumen can resist damage from extreme temperature fluctuations, as well as minor structural shifts from the building it’s placed on, because it is flexable (with a great resistance to brittleness)
- Modified bitumen roofing is air and water tight. Not only is it great for waterproofing, but it provides great insulation qualities as well, which can help keep a business’ energy costs from running up too high.
- Modified bitumen gets high rankings in regards to fire, wind, and hail ratings.
- The average life expectancy of a modified bitumen roof is some time between 15 and 20 service years with proper required maintenance
Generally, the installation process for modified bitumen will unfold as follows:
- Before installation, the old roof must be taken off to inspect the substrate, in order to determine whether it is appropriate for the new roof.
- Any repairs to the substrate will need to be made before installation can start.
- The installation of a vapor barrier and sloped insulation is common practice in most roof replacements to keep up with building code and increase energy efficiency.
- The next step is to apply the first layer of SBS modified bitumen base sheet, The roof will be waterproof just from the application of the first layer alone.
- A final layer, called the cap, is added after the first layer. This layer is covered in granules used to safeguard the initial coating from UV light.
- After the basic roofing installation is complete, metal flashings and other roofing elements are added on to finish the installation.
