Metal Roof Snow Load Ontario — ROOFNOW™ Guide

Ice dams form when snow melts unevenly on asphalt shingles and refreezes at the roof edge. Armadura® Metal Roofing significantly reduces this problem through controlled snow shedding and stable winter performance.

Why Ice Dams Occur

Warm interior air rises to the roof peak, melts snow, and creates water flow that refreezes over cold eaves. Asphalt shingles trap water and increase the severity of ice dams. Further science available at ROOFNOW™ Knowledge Center.

How Armadura® Prevents Ice Dams

• Steel surface releases snow predictably
• Even surface temperature reduces melting variations
• Interlocked seams block water penetration
