three. EPDM (Ethylene Propylene Diene Monomer)
A artificial rubber membrane recognized for sturdiness and easy servicing. It resists cracking and UV harm, rendering it ideal for extended-expression use in various Canadian temperature.
four. TPO (Thermoplastic Polyolefin)
only one-ply reflective roofing membrane that gives excellent Electrical power efficiency. It demonstrates daylight, assisting properties keep cooler throughout hotter months.
5. PVC (Polyvinyl Chloride)
PVC roofing presents superior waterproofing and chemical resistance. Its heat-welded seams give a watertight finish that will final for many years.

-
Request warranty protection for each resources and labour.
-
Discuss a upkeep strategy for seasonal inspections and treatment.
a specialist installation assures not simply general performance but assurance For many years to come back.
Innovative works by using of Flat Roofs in Canada
Flat roofs are no more only for commercial structures—they’re remaining creatively used throughout household and blended-use developments.
-
Rooftop Gardens and environmentally friendly Areas: These make improvements to insulation and reduce rainwater runoff.
-
Solar Installations: Flat surfaces are ideal for solar panels, which can be angled for exceptional sunlight.
-
Rooftop Patios: Homeowners can increase decks, seating places, or pergolas for outside living.
-
Eco-Friendly Builds: Flat roofs can integrate recycled components and Strength-conserving programs.
These uses transform what was after just a structural element right into a practical, aesthetic characteristic that improves property price.
way forward for Flat Roofing in Canada
