Western Pennsylvania is known for its rich history, rolling hills—and unpredictable weather. While the seasons bring beauty, they also bring unique challenges for homeowners when it comes to roof maintenance and performance.
At Gerken Roofing, we’ve served homeowners across the region for years and know exactly what your roof is up against. From freeze-thaw cycles to heavy rain and wind, here are the most common roofing issues in Western PA—and how we recommend addressing them.

1. Freeze-Thaw Damage
The Problem: Winter brings freezing temperatures and snow, followed by periods of thawing. Water seeps into small cracks or under shingles, freezes, expands, and causes materials to shift or break apart.
How to Fix It:
Install proper underlayment like ice and water shield to prevent moisture penetration.
Seal vulnerable areas like flashing, valleys, and around chimneys.
Annual inspections in late fall help catch cracks before winter hits.
2. Ice Dams
The Problem: Snow melts on a warmer roof, runs down to the colder eaves, and refreezes—causing ice buildup. This forces water under your shingles and can lead to serious leaks.
How to Fix It:
Improve attic ventilation and insulation to keep the roof temperature consistent.
Install ice and water barriers at eaves.
Consider heat cables in severe areas.
3. High Wind Uplift and Shingle Blow-Offs
The Problem: Spring and fall winds in Western PA can reach high speeds. Aging or poorly installed shingles are especially vulnerable to lifting or tearing off.
How to Fix It:
Use high-wind-rated shingles, like those from Atlas Roofing, which Gerken Roofing proudly installs.
Make sure your roof is properly nailed with correct spacing and pattern.
If damage occurs, replace missing shingles immediately to avoid further water intrusion.
4. Algae and Moss Growth
The Problem: High humidity, frequent rainfall, and shaded areas cause dark streaks, algae, and moss to grow—especially on north-facing slopes. These organisms trap moisture and deteriorate shingles over time.
How to Fix It:
Use algae-resistant shingles like Atlas Shingles with Scotchgard™ Protector.
Ensure proper gutter cleaning and drainage to avoid standing water.
Trim overhanging trees to increase sunlight and airflow.
5. Flashing Failures Around Chimneys and Skylights
The Problem: Older homes in Pittsburgh and surrounding areas often have brick chimneys and custom skylights. Over time, flashing materials degrade or separate, leading to leaks.
How to Fix It:
Replace old flashing with modern, rust-resistant metals.
Seal joints with high-quality roofing caulks or membranes.
Consider counterflashing installation for better long-term durability.
6. Gutter and Downspout Issues
The Problem: Heavy rain and falling leaves often clog gutters in Western PA, causing water to back up onto the roof or overflow near your foundation.
How to Fix It:
Install gutter guards to reduce clogs.
Regularly clean gutters in spring and fall.
Ensure downspouts extend away from your home by at least 4–6 feet.
7. Improper Installation from Past Contractors
The Problem: Older homes or recent homebuyers may be dealing with roofs that were installed with shortcuts or subpar materials—leading to premature leaks, poor drainage, or structural risks.
How to Fix It:
Get a professional roof inspection from a trusted local contractor like Gerken Roofing.
If repairs aren’t enough, consider a full roof replacement using modern materials and code-compliant installation methods.
Ask for warranties—we offer product and labor warranties on every job.
