Commercial Roof Inspection & Maintenance in Canada

Flat-roof inspections, drain clearing, and pre-winter preventive repairs.

Flat commercial roofs need semi-annual inspections — spring (post freeze-thaw) and fall (pre-snow-load). Cleared drains and sealed penetrations prevent the majority of winter leak claims.
