Winter in Pittsburgh isn’t just cold — it’s unpredictable. Snow one day, rain the next, freeze–thaw cycles overnight. While the season is beautiful, it’s also the toughest time of year for your roof. At EAS Roofing, we see more emergency calls during winter than any other season because the harsh weather exposes problems that have been building for months.
Here are the top winter roofing issues Pittsburgh homeowners should watch for, and how to spot them early before they turn into costly repairs.
1. Ice Dams — The #1 Winter Roofing Issue in Pittsburgh
Ice dams form when heat escapes into the attic, melts the snow, and then refreezes at the edges of the roof. This solid sheet of ice traps melting snow, forcing water to back up under the shingles.
Signs you have an ice dam:
Icicles hanging from gutters
Water dripping behind gutter lines
Uneven melting on your roof
Ceiling spots along outside walls
Ice dams can cause leaks, rot, mold, and major interior damage. Proper ventilation and insulation — which we check during an attic inspection — are the key to preventing them.
2. Attic Condensation & Frost on Nails
One of the biggest hidden roofing dangers in winter happens inside the attic. When warm indoor air rises and meets cold roof decking, condensation forms. Over time, this leads to:
Frost on roofing nails
Mold growth
Wet insulation
Wood rot
If your attic smells musty or you notice moisture on the wood, it’s a red flag. A winter attic inspection from EAS Roofing can identify the cause and help prevent damage before spring storms arrive.
3. Heavy Snow and Structural Stress
While Pittsburgh roofs are built to handle snow, several storms in a row or extremely wet snow can push your home to the limit.
Warning signs of snow-related roof stress:
Cracking or popping sounds
Sagging drywall
Bowed ceilings
Visible dips in the roofline
If you spot any of these, call us immediately. Roof integrity issues worsen quickly in winter.
4. Wind Damage to Shingles
Winter winds can gust well over 40–50 mph in the Pittsburgh area. Loose, aging, or improperly installed shingles can lift or blow off completely.
After a windy night, check for:
Shingles in your yard
Exposed nail heads
Flapping or shifting shingles
Missing ridge cap pieces
Even a single missing shingle can lead to winter leaks.
5. Gutter Freezing & Overflow Issues
Gutters are your first line of defense against winter water damage. When they freeze, clog, or pull away from the home, melting snow has nowhere to go.
This leads to:
Water intrusion
Fascia rot
Ice buildup
Foundation issues
EAS Roofing can help ensure your gutters are secured and functioning properly before the deep freeze sets in.
