How Ice and Snow Cause Winter Roof Damage (and What to Do About It)

As the temperatures drop and the first flakes start to fall, it’s easy to get caught up in the charm of winter. But while the snow might look pretty from the window, it could be causing serious issues on your roof. At Allied Exteriors Inc., we’ve seen firsthand how winter roof damage can sneak up on homeowners. The good news? There are simple steps you can take to protect your property from costly repairs.

Common Types of Winter Roof Damage

Your roof is your home’s first line of defense against the elements—but even the strongest roof can struggle under winter’s pressure. Here’s what to look out for:

1. Ice Dams

Ice dams form when heat from your attic melts the snow on your roof, and the water refreezes near the edge. This creates a ridge of ice that traps water behind it. The problem? That water has nowhere to go—so it can back up under your shingles and leak into your attic or walls.

2. Snow Load

Heavy snow buildup puts significant weight on your roof. Over time, that weight can cause sagging or even structural damage, especially if your roof is older or hasn’t been properly maintained.

3. Freeze-Thaw Cycles

When temperatures fluctuate between freezing and thawing, it can cause roofing materials to expand and contract. This stress can crack shingles, loosen flashing, and create openings for water to get in.

4. Clogged Gutters

Gutters filled with leaves, ice, or debris can’t do their job. Instead of draining water away from your home, they overflow, potentially damaging your siding, foundation, or roofline.

How to Protect Your Roof This Winter

Winter weather may be out of your control, but how you prepare your roof isn’t. Here are a few proactive steps you can take to prevent winter roof damage:

1. Schedule a Professional Roof Inspection

Before the worst weather hits, have a trusted contractor (like Allied Exteriors Inc.) inspect your roof for signs of wear, missing shingles, or potential trouble spots. Early detection means simpler, cheaper repairs.

2. Clean Your Gutters

Make sure your gutters are clean and clear of leaves or debris. Consider installing gutter guards for added protection. Proper drainage is key to preventing ice dams and water overflow.

3. Improve Attic Insulation and Ventilation

A well-insulated attic helps keep warm air in your living space—not leaking into your roof. Proper ventilation also helps regulate temperatures and prevent condensation buildup that leads to mold or wood rot.

4. Remove Snow Safely

Use a roof rake to clear snow from the edge of your roof after big storms. Avoid climbing up there yourself—leave the high-risk jobs to professionals with the right safety equipment.
