Quality Roofing Supply | Building Supplies & Roofing in Allentown, PA 18109

A new roof installation is for a newly constructed home or addition where there is no existing roof structure. A roof replacement involves removing the old, worn-out roofing materials (like shingles, underlayment, and flashing) down to the decking, inspecting and repairing the deck if needed, and then installing a brand-new roof system. At Quality Roofing Supply, we provide all the necessary materials for both processes, from underlayment and shingles to ice and water shield, ensuring your contractor has exactly what's needed for a proper, long-lasting installation in Allentown's climate.

Repairing wind damage often requires more than just replacing a few shingles. High winds can lift and compromise the underlying underlayment and flashing. For a proper repair in Allentown, you'll need matching shingles, new roofing felt or synthetic underlayment, and potentially new ridge caps, starter strips, and sealant. Our team can help you or your contractor identify the exact materials to match your existing roof and ensure the repair is weather-tight. We also supply reinforced synthetic underlayments that offer superior tear resistance for added protection against future storms common to our area.

Roof valleys, where two roof planes meet, are common leak points in Allentown due to heavy rain and snowmelt channeling a large volume of water. Leaks often occur from worn-out or improperly installed valley flashing. A permanent fix involves installing new, corrosion-resistant metal valley flashing (like galvanized steel or aluminum) or using a specialized ice and water shield membrane specifically designed for valleys. At Quality Roofing Supply, we carry these critical waterproofing products and can advise on the best solution for your specific roof type to prevent future leaks and protect your home's interior.
