J W Contractors Inc | General Contractors & Roofing in Allentown, PA 18104

Ice dams form when heat escapes into your attic, melting snow that refreezes at the eaves. In Allentown, a professional roofer like J W Contractors can help by improving attic insulation and ventilation to keep the roof deck cold. We also ensure proper sealing around vents and chimneys and install ice and water shield underlayment at the eaves. These preventative measures are crucial for protecting against the costly water damage and roof deck rot common in our area.

Signs include sagging roof lines, dark stains on interior ceilings or walls, a musty smell in the attic, and soft spots you can feel from the outside. As a local Allentown contractor, we start by safely removing damaged sections of roofing and sheathing. The underlying structure is inspected for any compromised rafters, which are then sistered or replaced. Finally, we install new, properly vented roof decking and high-quality underlayment before re-roofing, ensuring a long-lasting repair that addresses the root cause.

Yes, absolutely. As a full-service general contractor in Allentown, we manage the entire project from the roof repair down. This includes safely drying out affected areas, removing damaged drywall or insulation, treating for mold if necessary, and performing the interior reconstruction. Coordinating both the exterior roofing repair and the interior restoration under one roof ensures the job is done efficiently, correctly, and with a single point of accountability for Lehigh Valley homeowners.
