Components of Torch Down Flat Roof Installations

here are many different installation options for low-sloped or flat roof homes and buildings, depending on the requirements and preferences of the property owner. At Smart Roofing, we have the expertise and the experience working with many types of flat roofing materials. One of the more popular flat roof installation method is the torch-down flat roof system, which can be used on both residential houses and commercial buildings in the GTA.

There are many ways to install torch-down flat roof systems. For many of the homes and commercial buildings in the Toronto and Mississauga area, flat roof installation usually consists of the following layers:

    • Flat roof insulation:

      All low-sloped roofs or flat roofs require insulation that is properly nailed-down with the appropriate r-value insulation to deal with our Toronto winters.

    • Vapour Barrier:

      The vapour control layer is an essential layer to reduce the risk of condensation, which is an important layer for the climate we have in Toronto. This layer allows moisture to escape from within the home or building.

    • Fiber Board:

      The fiber board or cover board layer act as a substrate for the modified bitumen flat roof membrane. They come in various thicknesses and board sizes. The fiber boards must be installed properly to ensure that water will not pool in certain areas and cause faster deterioration of the flat roof.

    • Base sheet:

      Peel and stick base sheets are applied onto the fiber board, which acts as the water proof seal on flat roofs. Experienced flat roof installers will know the right amount of overlap to ensure that water will not get up under the seams.

    • Cap sheet:

      This is the top layer of a low-sloped rubber roof. A popular material used for flat roof installation is the modified bitumen torched down rubber. Experienced installer will know the proper amount of heat to apply so that seams are welded without destroying the rubber.
