7 Signs of Roof Damage Hiding Beneath Winter Snow
When winter sets in across Maine, it brings more than just postcard-perfect snowfalls. That thick blanket of white may look peaceful from the ground, but beneath it could be damage quietly compromising your roof’s integrity. Ice, wind, moisture, and fluctuating temperatures can all cause hidden issues that only reveal themselves when it’s too late.
At A Plus Roofing, we’ve seen how quickly a small unnoticed problem under the snow can turn into a major spring repair. Here are seven signs to look for so you can catch roof damage early—and save yourself the headache (and cost) of a major leak come thaw season.
1. Ice Dams Along the Roof Edge
Ice dams form when warm air escapes through your attic, melting the snow on your roof. That melted snow refreezes along the eaves, creating a solid ridge of ice. Not only can this block proper drainage, but it also traps water on your roof—forcing it under your shingles and into your home.
What to do: Keep gutters clear, add insulation to your attic, and have your roof professionally inspected if you see recurring ice dams.
2. Sagging or Uneven Rooflines
Snow is heavy—especially when it’s wet. Over time, that extra weight can cause your roof to sag or dip in certain areas. This isn’t just a cosmetic issue; it’s a red flag that the roof structure may be compromised.
Pro tip: If you notice any sagging from the ground, don’t wait until spring. Schedule a professional inspection immediately to ensure the structure is safe.
3. Water Stains on Ceilings or Walls
Those yellow or brown spots on your ceiling aren’t just an eyesore—they’re a sign that water has already found its way in. Snowmelt can sneak through cracked flashing, damaged shingles, or compromised underlayment, and by the time you see the stain, the leak may have been active for weeks.
Action step: Address any discoloration right away and have a roofer locate the source before it worsens.
4. Icicles Hanging from the Gutters
They may look picturesque, but icicles often signal poor attic ventilation or blocked gutters. Both conditions lead to trapped moisture that can back up under shingles and cause rot, mold, or shingle failure.
Roof tip: Regularly clear your gutters and ensure your attic is ventilated properly to balance temperature and airflow.
5. Missing or Loose Shingles
High winds and freeze-thaw cycles can cause shingles to crack, curl, or even blow off entirely. Unfortunately, with snow covering your roof, you might not notice until water starts leaking into your attic.
Look for clues: After a storm, check your yard for fallen shingles or granules near downspouts. These are telltale signs that your roof needs attention.
6. Gutter Debris or Shingle Granules
When snow begins to melt, take a look at what’s coming out of your gutters. If you spot an unusual amount of black or gray granules, your shingles are breaking down from age or damage. Once the protective layer erodes, your roof becomes more vulnerable to leaks and UV damage.
Maintenance tip: Granule loss is often an early warning sign that it’s time to schedule a professional roof inspection.
7. Drafts or Temperature Swings Indoors
If you notice cold drafts, fluctuating temperatures, or higher heating bills during the winter, your attic insulation or ventilation may be compromised due to roof damage. Moisture infiltration and air leaks often go hand-in-hand with structural wear above.
Solution: Have your attic and roof evaluated for air leaks, damaged decking, or missing insulation to restore energy efficiency.
Don’t Wait Until the Snow Melts
By the time spring arrives, what began as a small leak under the snow could lead to rotted decking, mold growth, or costly interior repairs. A mid-winter roof inspection can uncover hidden problems before they escalate.
