J.O.N. Construction | Roofing Services in Allentown, PA 18106

As one of the few GAF Master Elite Contractors in the Lehigh Valley, it signifies our factory-certified training and access to premium GAF roofing systems. For you, it means a stronger warranty, superior materials designed for our climate, and an installation backed by one of the industry's leading manufacturers. This certification is our commitment to providing Allentown homeowners with roofing solutions that offer lasting protection and value.

These are frequent concerns for Allentown homes. For ice dams, we focus on proper attic ventilation and insulation during a roof repair or replacement to prevent heat from escaping and melting snow unevenly. For dark algae stains, we can install algae-resistant shingles, which are a standard part of our GAF systems. These shingles have copper granules that inhibit algae growth, keeping your roof looking cleaner and protecting its lifespan against our humid Pennsylvania summers.

Yes, we provide comprehensive service for both. We can often repair isolated sections of siding or a leaking gutter seam, which is a cost-effective solution for minor damage. However, if an inspection reveals widespread wear, aging, or underlying issues—common after 30 years of Lehigh Valley weather—we will recommend a full replacement. This ensures complete protection for your home's structure and gives you the benefit of modern, more efficient materials with a new warranty.
