Metal Roof Snow Load Ontario — ROOFNOW™ Guide

Winter is the leading cause of roof leaks in Ontario. Ice dams, trapped moisture, and freeze–thaw cycles overwhelm asphalt shingles. Armadura® Metal Roofing prevents leaks through moisture-resistant steel construction and interlocking protection.

Why Winter Leaks Occur

Asphalt shingles absorb water, crack under cold, and allow meltwater penetration. Winter weather accelerates roof failures. Learn more at: ROOFNOW™ Knowledge Center.
