Challenges in selecting the right roofing membrane

Before choosing a new roof membrane, we must analyze your expectations, your budget and the building characteristics. First and foremost, the covering must be adapted to the type of building, the flat roof structure and the facilities in place. Traffic on the flat roof and amount of maintenance are also important.
After that, a budget must be established to be able to choose the type of roofing membrane and materials required for the work. Moreover, it is important to know and to respond to the regulations in place in your district or municipality in relation to the Solar Reflectance Index (SRI) number required of the roofing membrane.
If you prefer to conduct the needs analysis on your own, it is still recommended that you speak with an experienced roofer to make sure of the following:

  • Quality and type of roofing membrane
  • Durability and warranty components
  • Longevity and installation compliance

Your decision should also take any future projects into account to anticipate how they may affect the roofing system. For example, if you are planning an addition to the building, select a system that will facilitate the additional components, ventilation systems and accessories on the roof.

This way, your investment will last longer and will respond to both your short- and long-term needs.
