1. Check for Damaged or Missing Shingles

Your shingles protect your home from rain, snow, and ice. Damaged or missing shingles leave your roof exposed. Take a good look and see if any are cracked, curled, or completely gone. Even one missing shingle can cause water leaks, so don’t wait to get it fixed.

2. Clear Out Roof Valleys

Roof valleys are the grooves where two sections of the roof meet. Snow, leaves, and other debris love to collect here, which can block water from draining properly. Check these spots and clear out any buildup to avoid water damage or leaks. Roofing in winter is easier without these issues.

3. Inspect Flashing and Sealant

The flashing around chimneys, vents, and skylights keeps water from sneaking into your home. This is why inspecting them should be part of your winter roof inspection checklist. If they are loose, cracked, or missing, water could get inside. Check the sealant around these areas too—if it’s worn out, it’s time to reapply.

4. Watch for Ice Dams

Ice dams happen when melting snow refreezes at your roof’s edges, blocking water from draining. This water can back up and seep under your shingles. Look for thick ice buildup near the edges of your roof. If you see ice dams forming, you can call professional roofing contractors to remove them safely.

5. Clean Your Gutters and Downspouts

Clogged gutters and downspouts can cause water to overflow, freeze, and damage your roof. Use a ladder to remove leaves, sticks, and other debris. Check that water flows freely through your downspouts and away from your home’s foundation.

6. Check Your Attic Insulation and Ventilation

Your attic plays a big role in keeping your roof healthy during winter. Without proper insulation, heat escapes and melts snow on your roof, which can cause ice dams. Make sure your attic is well-insulated and has proper airflow to keep things balanced.

7. Look for Roof Sagging

Heavy snow can be tough on your roof. Check for any sagging areas or uneven spots. This could mean your roof is under too much pressure or has underlying damage. Don’t ignore this—call a professional roofing company right away if you spot anything unusual.

8. Check for Moss or Algae

Moss and algae can grow on your roof over time, trapping moisture and damaging shingles. Look for green patches or dark streaks on your roof. If you see any, clean the area or call in a roofing company to handle it.

9. Inspect Roof Vents and Chimney

Blocked vents and chimneys can lead to serious issues, like poor airflow or even carbon monoxide buildup. Make sure they’re clear of snow, ice, and debris. If you notice any blockages, clear them right away.

10. Look for Signs of Leaks Inside

Don’t forget to check inside your home! Look at your ceilings and walls for water stains, discoloration, or peeling paint. These could be signs of a roof leak. Catching leaks early can save you a lot of trouble and money.

11. Schedule a Professional Roof Inspection

While a DIY inspection helps, nothing beats a professional’s expertise. Certified roofing contractors follow a comprehensive winter roof inspection checklist so they know exactly what to look for. They can identify potential issues you might miss and recommend repairs or maintenance to keep your home safe through winter.
