Flat-roof replacement
in Saint-Marc-sur-Richelieu.
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 Saint-Marc-sur-Richelieu, with the assembly selected to suit the building and the project.
