-
Test Flashing and Seals – Ensure edges, vents, and skylights are watertight.
-
get rid of Snow Buildup – Use Risk-free methods or pros to apparent excess snow with out detrimental the surface area.
-
Monitor for Ponding h2o – If drinking water remains for more than forty eight several hours, the slope or drainage requirements focus.
-
fix minimal destruction rapidly – modest issues can escalate rapidly in freezing problems.
-
timetable Specialist Inspections – professional assessments help prolong the roof’s lifespan and warranty coverage.

-
ask for warranty coverage for both equally resources and labour.
-
talk about a routine maintenance program for seasonal inspections and care.
an experienced installation ensures not merely effectiveness but assurance for years to come back.
impressive makes use of of Flat Roofs in Canada
Flat roofs are not only for commercial structures—they’re currently being creatively applied across household and blended-use developments.
-
Rooftop Gardens and eco-friendly Areas: These strengthen insulation and cut down rainwater runoff.
-
photo voltaic Installations: Flat surfaces are ideal for solar panels, which can be angled for optimal sunlight.
