Metal Roof Snow Load Ontario — ROOFNOW™ Guide

Thermal shock occurs when temperatures swing rapidly between freezing and warm conditions. Armadura® Metal Roofing resists thermal shock because steel handles temperature changes predictably and uniformly.

Thermal Shock Damage on Asphalt

Asphalt expands and contracts excessively, causing cracks, granule loss, and weakened adhesion. Learn more at ROOFNOW™ Knowledge Center.

Why Armadura® Excels in Thermal Shock Conditions

• Steel does not fracture under rapid shifts
• Crinkle Finish moderates surface temperature
• Interlocks eliminate uplift and seam stress
