Common Roofing Challenges in Western Pennsylvania

How Local Weather and Environment Impact Your Roof

Owning a home in Western Pennsylvania comes with its fair share of roofing challenges. With unpredictable weather patterns, seasonal extremes, and a unique topography, the conditions here can put roofs to the test.

At Gerken Roofing, we’ve served homeowners throughout the region for years—and we’ve seen it all. Here's a look at the most common roofing challenges Western PA homeowners face and how to address them before they become costly problems.

1. Heavy Snow and Ice Dams

Winters in Western PA can bring significant snowfall. When snow builds up on your roof and temperatures fluctuate, it can lead to the formation of ice dams—thick ridges of ice that block melting snow from draining. This trapped water can back up under shingles and leak into your home.

Solution: Proper attic insulation and ventilation can help regulate roof temperature, while installing ice and water shield barriers during a new roof installation adds extra protection.

2. Frequent Freeze-Thaw Cycles

Our region sees frequent temperature shifts, especially in fall and spring. This causes materials to expand and contract, leading to cracks in shingles and flashing. Over time, this can result in water intrusion and leaks.

Solution: Annual roof inspections can catch damage early. Replacing aging materials before they fail is key to avoiding interior water damage.

3. High Winds and Storm Damage

Thunderstorms and high winds are common in the warmer months. Shingles can lift, tear, or be blown off completely. Flashing and gutters are also vulnerable.

Solution: Architectural shingles and storm-rated roofing materials offer better resistance. After severe weather, a professional inspection can ensure hidden damage isn’t left to worsen.

4. Moss and Algae Growth

The mix of shade, humidity, and precipitation in our area makes roofs susceptible to moss, mold, and algae—especially on north-facing slopes.

Solution: Choose algae-resistant shingles, and consider zinc or copper strips at the roof ridge to naturally inhibit growth. Keep trees trimmed back to reduce shade and debris.

5. Gutter Clogs from Fall Leaves

Western PA’s beautiful trees create another issue—clogged gutters. When gutters overflow, water can back up under the shingles and into the fascia, soffits, or even foundation.

Solution: Gutter guards are an affordable, effective way to reduce clogs and direct water away from your home year-round.
