Pennsylvania's housing stock includes a mix of older homes with slate or metal roofs and newer constructions predominantly using asphalt shingles. Flat or low-slope roofs are also common, especially on row homes and commercial buildings. For these applications, TPO offers excellent durability and resistance to the state's freeze-thaw cycles and heavy precipitation. Our process begins with a comprehensive roof inspection to assess existing damage and structural soundness. We then discuss material options, focusing on their performance and longevity in Pennsylvania's varied weather conditions.
Common questions
What roofing materials are best for Pennsylvania's climate?
For Pennsylvania's climate with its hot summers and cold, wet winters, asphalt shingles with good UV and impact resistance are suitable for sloped roofs. TPO is highly recommended for flat or low-slope roofs due to its durability against freeze-thaw cycles and heavy rain. We prioritize materials that withstand wind and snow loads.
How does Pennsylvania's weather affect roof repair costs?
