A number 1 Roofing: Licensed Roof Repair Serving Pittsburgh, PA 15227

Shingle curling in Pittsburgh is often caused by thermal expansion and moisture. Our new roof installations use premium, climate-rated shingles with strong sealing strips and proper attic ventilation systems. This combination prevents heat and moisture buildup under the roof deck, which is a primary cause of curling, ensuring your new roof lays flat and performs for decades.

Absolutely. Corroded flashing is a critical failure point, especially with our freeze-thaw cycles. A proper roof replacement isn't complete without replacing all step, valley, and chimney flashing with new, corrosion-resistant materials. We install heavy-duty, galvanized or aluminum flashing to create a watertight seal that protects your home's most vulnerable intersections for years to come.

For durability against Pittsburgh's moisture and temperature swings, we strongly recommend architectural asphalt shingles for their weight and wind resistance, paired with ice and water shield along the eaves. We also use synthetic underlayment for superior moisture protection. This system is specifically chosen to combat the root causes of local problems like curling and corrosion.
