Why metal roofing holds up in this part of Pennsylvania
The weather in South Central Pennsylvania — heavy snow, freeze-thaw cycles, summer storms rolling through the Cumberland Valley — puts traditional asphalt shingles through a lot. Homeowners in Gettysburg, Waynesboro, Chambersburg, and the surrounding townships deal with conditions that favor steel:
Lifespan
40–70+ years with proper installation — likely the last roof you’ll ever put on
Snow and ice
Steel panels shed snow faster than shingles, reducing ice dam formation and structural load through the winter
Wind resistance
A correctly installed steel roof holds up to high winds far better than individual shingles that can lift, crack, or blow off
Low maintenance
No granule loss, no moss, no cracked or missing shingles to deal with every few years
Energy efficiency
Steel panels reflect heat, which can reduce cooling costs through Pennsylvania summers
Warranties
Lifetime material warranties plus our workmanship warranty on every full replacement
Residential metal roofing
We work on single-family homes, ranches, Cape Cods, farmhouses, and multi-unit residential properties throughout the region — from Gettysburg and New Oxford in Adams County to Chambersburg, Waynesboro, and Greencastle to the west.
Every residential job gets the same approach: proper underlayment, correct flashing at every penetration and edge, and clean panel alignment throughout. If you're deciding between a roof repair and replacement, we’ll give you an honest assessment of your current roof and a clear, itemized estimate before any work begins.
Agricultural and farm building roofing
Farm structures — barns, pole buildings, equipment storage, grain facilities, and livestock buildings — have demands that most residential contractors don’t think through carefully. Large spans. Ventilation requirements. Constant exposure to moisture and corrosive environments.
Metal is the right call for agricultural buildings, and it’s a significant part of our work. Whether you’re in the farmland outside Biglerville, the rural townships around Mercersburg, or anywhere else in the region, we understand what these structures need and how to work on a functioning farm property.
Owner on site for every job
Most roofing companies in the Gettysburg and Chambersburg area send a crew. The owner handles estimates and checks in on bigger jobs, but the people doing the work are employees or subcontractors you haven’t met.
At Appalachian Exteriors, the owner is the primary installer on every full replacement — on site, hands-on, from the first panel to the last piece of trim. There’s no gap between what was promised and what gets installed.
