Winter in Northern Nevada doesn’t mess around. Whether you’re in Reno proper or closer to Tahoe and Truckee where snow loads get serious, your roof is about to face months of punishment from snow, ice, wind, and wild temperature swings. The question isn’t whether winter will test your roof—it’s whether your roof is ready for the test. A quick inspection now can save you from emergency tarping at 2 AM when it’s 20 degrees outside and your ceiling is dripping.
Here’s the thing most homeowners don’t realize: winter roof damage rarely starts in winter. It starts with small problems you didn’t catch in fall—a loose shingle here, a clogged gutter there, some flashing that’s been quietly failing since July. Then the first big storm hits, water finds that weak spot, freezes, expands, and suddenly you’re dealing with a leak that’s going to cost you ten times what prevention would have. Let’s make sure that doesn’t happen.
Your 10-Point Winter Roof Inspection Checklist
- Check for Missing, Cracked, or Curling Shingles
Walk around your property and look up. You don’t need to get on the roof (please don’t—that’s what we’re here for), but you should be able to spot obvious problems from the ground. Missing shingles are open invitations for water. Curling edges mean your shingles are past their prime and won’t handle freeze-thaw cycles well. - Inspect Flashing Around Chimneys, Vents, and Skylights
Flashing is the metal that seals the gaps where your roof meets things that poke through it. It’s also the number one place roofs leak. If the flashing is rusty, bent, or has gaps, water will find its way in. This is especially critical in areas that see heavy snow—when that snow melts and refreezes, even tiny gaps become major problems. - Clear Your Gutters and Downspouts Completely
Clogged gutters don’t just overflow—they create ice dams. When water can’t drain properly, it backs up under your shingles, freezes, and forces its way into your home. Before the first snow, make sure every gutter and downspout is clear. If you’re near Tahoe where snow gets measured in feet, not inches, this isn’t optional. - Look for Granule Loss in Gutters
While you’re cleaning gutters, check for those little sandy granules that look like coarse pepper. Some granule loss is normal, but if your gutters look like a sandbox, your shingles are wearing out fast. Winter will accelerate that deterioration. - Examine Soffit and Fascia for Rot or Damage
The soffit (underside of your roof’s overhang) and fascia (the board running along the roof edge) protect your roof structure. If they’re rotting or damaged, moisture is already getting where it shouldn’t. Winter will make that exponentially worse. - Check Attic Ventilation and Insulation
Go into your attic. Seriously—this is where a lot of winter roof problems actually start. Poor ventilation and insulation create temperature imbalances that lead to ice dams. You should see daylight through your vents, and your insulation should be evenly distributed with no compressed or missing spots. If your attic feels warm in winter, that heat is melting snow on your roof, which refreezes at the edges. That’s how ice dams form. - Inspect for Signs of Pest Damage
Birds, squirrels, and other critters love to nest in roof structures before winter. Check for holes, nesting materials, or droppings in your attic and around roof edges. A small hole becomes a major moisture entry point once snow arrives. - Look at Roof Valleys
Valleys—where two roof planes meet—channel a ton of water. They also collect snow and debris. Make sure valleys are clear and the shingles there aren’t worn or damaged. Valley failures cause some of the most destructive leaks. - Check Your Chimney Cap and Crown
If you have a chimney, make sure the cap (the metal cover on top) is secure and the crown (the concrete top) isn’t cracked. Water getting into your chimney doesn’t just damage the chimney—it gets into your home. - Assess Overall Roof Age and Condition
Be honest with yourself: how old is your roof? Most asphalt shingle roofs last 20-25 years in our climate. If yours is pushing that age and showing wear, winter might be the season that pushes it over the edge. Planning a replacement in spring beats an emergency replacement in January.
Why Mills Roofing Gets Called Before Every Storm
For over four decades, Mills Roofing has been the name Reno and Northern Nevada homeowners trust when it matters most. We’re not just installers—we’ve built an entire training program to make sure every person on our crew knows exactly what to look for and how to fix it right the first time. That kind of expertise doesn’t come from a weekend certification course. It comes from decades of Reno winters, thousands of roofs, and a commitment to keeping our neighbors dry.
We’ve seen what happens when homeowners skip the fall inspection. We’ve tarped roofs in blizzards, replaced plywood that could’ve been saved, and helped families deal with insurance claims that could’ve been prevented. We’d rather spend an hour inspecting your roof in November than see you deal with that stress in January. A professional inspection catches what you can’t see from the ground—the subtle signs that separate “totally fine” from “disaster waiting to happen.”
What Happens Next?
If you’ve gone through this checklist and everything looks good, you’re ahead of most homeowners. Keep an eye on things as winter progresses, especially after heavy storms. If you found issues—or if you’re just not sure what you’re looking at—let’s get someone out there before the snow flies. Mills Roofing offers thorough pre-winter inspections throughout Reno, Sparks, and up into Tahoe and Truckee. We’ll tell you exactly what’s going on, what needs attention now, and what can wait until spring.
