Q : What is TPO roofing membrane
A : The TPO roofing membrane has high performance energy features. The clear surface reflects sunligh, therefore energy consumptions of both cooling and heating systems of all categories. The membrane never cracks and never shrinks. It has high-hold time resistance to ultraviolet rays a and it also features a bacterial contamination chemical prevention design. (More info)

Q : Why is TPO roofing membrane better than tar & gravel / elastomeric membrane?
A : When it comes to TPO roofing membrane in comparison to tar & gravel, lightness is the main benefit and makes it considerably more resistant to weight such as snow for the winter or even a roof terrace. Hot air welded, unlike elastomeric membrane, our TPO membrane drastically reducing the risk of accidental fire during the work process. It also helps maintaining fresh temperature of your building for the summer and therefore helps extending your heating and cooling equipment lifespan if they have units located on the rooftop.

Q : How can I tell if the shingles on my roof needs to be changed?
A : In most cases, not to say every time, shingles is guaranteed by the manufacturer (15 years, 20 years, 25 years, 30 years, 40 years, lifetime, …). Once your coverage will be coming to an end (preferably 2 to 3 years before the end), it is strongly recommended to request a preventive inspection to ensure the shingles conditions and to request a global estimate in order to make sure that we have proper waterproofness and avoid water damages. If you do not know when the roofing material was installed, it would be best to have it inspected out of prevention. The crucial elements to look after are :

  • The erosion of your shingles (when looking from the ground up, underneath the edges, you will notice small pieces of black asphalt)
  • Verify if the shingles are peeling off and/or curling

Q : My shingle roof was recently installed and the shingles seems to be curling already. Is that normal?
A : Absolutely. The shingles need to settle before they appear to be straight and even as the sun and heat are contributing to the final result. Usually, a drastic change will take effect after a while. If you are in the process of getting the roofing work done during springtime, at the end of summertime or after excessive heat (depending on the temperature), you will definitely notice a difference. If your roof top was change after the heat (usually between September and November), the snow will help the shingles straighten out. Therefore, those changes will be noticeable for springtime, once the majority of the snow is melted.

Q : Do you put something between the wood deck and the shingles?
A : Certainly. In order to be accredited by the shingle manufacturers, to be eligible for the coverage and to secure optimal waterproofness, a 6 feet wide stick-on membrane will be applied along the edges as well as #15 black paper over the entire roofing surface to provide optimal protection for the decking.
