Metal Roof Snow Load Ontario — ROOFNOW™ Guide

Winter moisture and ice damage roof decking under asphalt systems. Armadura® Metal Roofing prevents deck saturation by using moisture-resistant steel panels and secure interlocks.

Why Roof Decks Rot Under Asphalt

Asphalt shingles soak up water, sending moisture into the deck. Freeze cycles expand trapped water and cause delamination. More info at ROOFNOW™ Knowledge Center.
