  • TPO and EPDM membrane

These membranes have a service life of 20 years—or even more—and require little maintenance. They provide exceptional resistance to fire, bacteria and mold, as well as various air pollutants. Material of choice for re-roofing and new roofs, they also provide great resistance to UV rays and can withstand considerable temperature variations. Like the TPO membrane, EPDM has a lifespan of 20 years or more, and these 2 materials are 100% recyclable at the end of their service life.

  • Elastomeric Bitumen

This material has a service life of between 20 to 25 years and can even last more than 30 years if it is regularly maintained (a minimum of twice per year). You must also ensure that your roof is properly ventilated.

  • Asphalt and gravel

With poor maintenance, a multilayer asphalt membrane will have to be replaced after 15 to 20 years. However, if you properly take care of it, it could last from 25 to 30 years. The most important is to ensure that the gravel stays in place to avoid damages caused by the sun. It is also essential to repair cracks in the membrane without delay, to prevent water infiltrations.

  • Green roofs

As well as being pretty, these roofing systems help to regulate the roof temperature, to improve sound absorption and to protect the membrane. Of course, these roofs will last for many years!

No matter what type of covering you will choose, a rigorous maintenance of your roof and prompt repair of all tears are primordial to not only avoid having to replace the whole roof, but also to prevent damage to the structure as well as water infiltration.
