Flat-roof replacement

Replacing a flat roof involves more than installing a new membrane. The deck, insulation, vapour control, slopes and waterproofing details all contribute to the result. Secure-Toît uses a white 60 mil TPO membrane for its TPO replacement work in Mercier, with the assembly selected to suit the building and the project.

Before you start.
How do I prepare a request in Mercier?
Include Mercier, the full address, phone number and service you need. Add relevant observations and access constraints. The request page automatically carries over your chosen area and service.
Why do you use 60 mil TPO?
It is the thickness selected for our TPO replacement work, approximately 1.52 mm. Roof performance also depends on the complete assembly, installation and treatment of details.
Are price and timing the same for every building?
No. Roof area, deck, access, equipment and agreed work need to be assessed. Availability is confirmed by the team; this page does not reserve an intervention time.
