A quality architectural shingle installed correctly typically lasts 20 to 27 years in a Pennsylvania climate - GAF's Timberline HDZ, the line we install most, is engineered for decades of service with LayerLock technology and a 15-year WindProven wind warranty. Shade, attic ventilation and storm exposure all affect real-world lifespan, which is why annual inspections matter.
Metal roofing lasts 40 to 70 years and sheds snow well, but it typically costs 30-50% more upfront than shingles. Asphalt shingles cost less, install faster and suit most Lehigh Valley homes. We install both - plus Polyglass low-slope systems - and will walk you through the payback math for your specific roof before you commit to either one.
Roof warranties have two parts: the manufacturer's coverage on materials and the contractor's guarantee on labor. GAF shingles carry limited warranties with 25 or 30 years of non-prorated misapplication coverage when installed by a certified contractor, and Lehigh Gap Exteriors adds a 10-year written workmanship guarantee on every job. Ask us to explain both at your free estimate.
We install GAF and Owens Corning asphalt shingles - both manufacturers list us as a contractor - plus Everlast metal roofing and Polyglass membrane systems for low-slope and flat roofs. Brand choice affects warranty coverage, color options and curb appeal, so we bring samples to your free estimate and match the system to your home, budget and exposure.
Most shingle roof replacements in the Lehigh Valley are completed in one to two working days, weather permitting - tear-off, deck repairs, underlayment, new shingles and full cleanup. Larger or steeper roofs, hidden deck damage and low-slope systems can add time. We schedule around the forecast, protect your landscaping, and back the finished roof with our 10-year workmanship guarantee.
