PVC membrane roof

PVC membranes are ideal for commercial or industrial roofs. They are mainly installed on roofs with large spaces without obstacles. The installation of these membranes is done in a single layer. The membrane is cut with scissors around the various elements of the roof, such as access hatches, vents and skylights.

Attention! Unlike the elastomeric membrane, this coating has a number of joints to be carefully inspected to prevent water infiltration. The waterproofing of a flat roof is essential, so be sure to entrust the installation, inspection and maintenance of your roof to professionals.

EPDM membrane roof

Similar to the PVC membrane, the EPDM membrane is distinguished by its installation. Since it is not thermofusible, the joints of the membrane are made with a special glue or an adhesive tape. It can also be installed under a layer of gravel. The lifespan of an EPDM membrane roof is between 15 to 17 years, just like the PVC membrane.

TPO membrane roof

The TPO membrane has advantages and characteristics similar to the PVC membrane. It is also installed by thermofusion and is easy to maintain. Since its lifespan is also 15 to 17 years, you won’t have to worry about having to do a roof repair for a long time.
