If you're a homeowner in Pittsburgh, you already know how unpredictable the weather can be. From harsh winter snowstorms to humid summers and surprise wind gusts in the fall, your roof takes a beating year-round. At Gerken Roofing, we’ve seen firsthand how Western Pennsylvania’s unique climate can affect your home’s first line of defense.

Let’s break down how Pittsburgh’s weather impacts your roof—and what you can do to protect your investment.

How Pittsburgh Weather Impacts Your Roof (and What to Do About It)

1. Winter Snow and Ice

Snow accumulation and ice dams are some of the biggest winter threats to your roof in Pittsburgh. When snow melts and refreezes at the edges of your roof, it creates ice dams that prevent proper drainage. Water can back up under your shingles, leading to leaks, rotting wood, and even mold growth.

What You Can Do:

Make sure your attic is properly insulated and ventilated to prevent heat loss.
Keep your gutters clear of debris to allow melting snow to drain.
Consider installing a snow and ice shield during your next roof replacement.

2. Freeze-Thaw Cycles

Pittsburgh often experiences dramatic temperature swings in late fall and early spring. These fluctuations cause roofing materials to expand and contract repeatedly, weakening shingles and flashing over time.

What You Can Do:

Schedule an annual inspection with Gerken Roofing to catch small issues early.
Look out for cracked or curling shingles after a freeze-thaw cycle.

3. Summer Heat and Humidity

While Pittsburgh isn't known for extreme heat, prolonged sun exposure and high humidity levels can cause roofing materials to degrade faster. Shingles may blister, warp, or lose their granules, reducing your roof’s ability to shed water.

What You Can Do:

Choose high-quality, UV-resistant shingles like those from Atlas, which Gerken Roofing proudly installs.
Ensure proper roof ventilation to reduce heat buildup in your attic.

4. Heavy Rain and Wind

Pittsburgh’s storm seasons often bring heavy rainfall and gusty winds that can damage shingles, flashing, and even roof decking. Poor drainage or clogged gutters can lead to pooling water and leaks.

What You Can Do:

Keep your gutters and downspouts clean and functional.
After a major storm, schedule a roof inspection—even if you don’t see obvious damage.
Make sure flashing and seals are properly maintained.

5. Falling Leaves and Debris

In the fall, Pittsburgh’s beautiful foliage can lead to clogged gutters and debris accumulation on your roof. If not removed, these materials can trap moisture and lead to mold or rot.

What You Can Do:

Clean your gutters at least twice a year.
Trim overhanging tree branches to minimize debris on the roof.
Consider adding gutter guards to reduce buildup.
