Quick Answer

Before Detroit’s snow and freezing rain arrive, make sure your roof is clean, sealed, and professionally inspected. GAF Roofing recommends homeowners schedule fall maintenance to prevent ice dams, leaks, and insulation issues. In Michigan’s cold, damp climate, proper ventilation and attic insulation are essential to keeping your roof in top condition all winter.

Why Winter Roof Prep Matters in Metro Detroit

Michigan’s winters are among the harshest in the Midwest, snow, sleet, and freeze-thaw cycles put serious stress on roofing systems. According to the Michigan Department of Licensing and Regulatory Affairs (LARA), roof collapses and water infiltration are among the most common winter home insurance claims in Southeast Michigan.

For Metro Detroit homeowners, preparing early can prevent costly emergency repairs. Manufacturers like GAF advise annual fall inspections to identify leaks, cracked shingles, or ventilation issues before the first heavy snowfall.

Steps to Prepare Your Roof for Michigan Winters

1. Schedule a Professional Roof Inspection

A qualified roofing contractor in Metro Detroit, such as Great Lakes Home Remodeling, a GAF-certified company, can check for loose flashing, worn sealant, or small leaks that could turn into major problems once snow accumulates.

GAF’s maintenance guide emphasizes annual inspections as the best defense against premature roof failure, especially on homes 10+ years old.

2. Clear Debris, Branches, and Gutters

Clogged gutters trap water and create ice dams when temperatures drop. Michigan State University Extension recommends cleaning gutters in late fall and trimming overhanging branches to prevent roof damage from falling ice or limbs.

3. Check Attic Insulation and Ventilation

The Michigan Residential Code requires balanced ventilation to minimize condensation. Poor airflow causes heat to build up in your attic, melting snow unevenly and refreezing it at the eaves. GAF’s Cobra® Vent System helps balance temperature and humidity levels to prevent ice dams.

4. Inspect Flashing and Sealants

Even a small gap in flashing can allow melting snow to seep inside. Focus on chimneys, vents, skylights, and valleys. GAF recommends using flexible, weather-rated sealants to handle Michigan’s temperature swings.

5. Address Ice Dams Before They Form

Ice dams occur when melted snow refreezes at the roof’s edge, forcing water under shingles. The Michigan Department of Insurance and Financial Services suggests installing heat cables or adding insulation to mitigate this. If your roof repeatedly forms ice dams, call a professional to inspect your attic ventilation.

Should You Handle Roof Prep Yourself or Hire a Pro?

While simple tasks like cleaning gutters or removing small debris can be DIY, inspecting flashings, sealing penetrations, or checking attic airflow requires a licensed professional. In Metro Detroit, hiring a GAF-certified roofing contractor like Great Lakes Home Remodeling ensures compliance with state licensing rules and preserves your manufacturer warranty.

Professionals also use infrared tools to detect trapped moisture, something DIY homeowners can’t easily spot.
