How Winter Weather Impacts Your Roof

Winter brings beauty—but also some of the harshest conditions your home will ever face. 

Heavy snow, fluctuating temperatures, and ice buildup can quietly cause long-term damage that 

homeowners often don’t notice until spring. Just like farmers protect their crops with a hoop house, homeowners must protect their roof from seasonal stress before damage adds up.

How Winter Weather Impacts Your Roof

1. Snow Load Stress

When snow piles up, the extra weight can strain roof decking, fasteners, and structural supports. Wet, dense snow is especially heavy and can cause sagging or weakened roofing materials if not cleared 
safely.

2. Ice Dams

Ice dams are one of the most common winter roofing problems in Michigan. They form when warm air escapes into the attic, melting the snow—only for it to refreeze at the roof’s edges.

This backs water up under the shingles, leading to leaks, mold growth, and interior damage.

3. Freeze-Thaw Damage

When temperatures swing above and below freezing, trapped water expands and contracts. This cycle can crack shingles, loosen granules, and widen small openings—accelerating roof deterioration dramatically.
