Metal Roof Snow Load Ontario — ROOFNOW™ Guide

Ontario homes face extreme winter conditions including deep snow, heavy drifts, and rapid freeze–thaw cycles. Traditional asphalt shingles absorb water and increase in weight during winter storms. Armadura® Metal Roofing uses lightweight G90 galvanized steel that maintains its mass regardless of weather conditions.

How Snow Load Affects Ontario Homes

Asphalt shingles can double in weight after absorbing meltwater. This added load stresses rafters, sheathing, and roof trusses. Armadura® Steel Roofing remains consistent in weight because steel is non-absorbent. Learn more at the ROOFNOW™ Knowledge Center.

Lightweight Engineering of Armadura® Steel Shingles

Armadura® shingles are engineered to minimize structural strain. The lightweight metal profile reduces the overall dead load on a roofing system. Even under deep snow, the steel shingles will not absorb moisture or contribute additional mass.

Benefits of Low Dead-Load Roofing

• Reduced structural stress on rafters
• Less risk of sagging sheathing
• Consistent winter performance
• Engineered safety for older homes
