Amish Roofing Contractor Serving Southwestern Pennsylvania
Platinum Home Exteriors is based in Millersburg, Ohio, in the heart of Holmes County, which holds the largest Amish community in the world. That's where our crews come from. We've been sending those crews into Pennsylvania because the territory makes sense: Beaver, Washington, and Greene Counties sit directly across the state line from the Ohio counties where we've done most of our work, and homeowners in this part of PA deal with the same weather, the same aging housing stock, and the same questions about who to trust on their roof.
Southwestern Pennsylvania is coal country and river valley country, and the homes here reflect that history. A lot of these houses have had one roof replacement since they were built, maybe two, and they're now at the far end of what that second roof was expected to do. Our crews come from a tradition that takes the work seriously, and our business runs on the kind of reputation that gets built one roof at a time in communities where word travels.

3 Counties, Around 220,000 Homes
Beaver, Washington, and Greene Counties together contain roughly 220,000 housing units, and the housing stock skews old. Washington County's Census Bureau data puts the median build year at 1954, which tells you what most of our inspection findings look like in this territory: original chimneys from the mid-century build, valleys that have been patched over instead of properly repaired, and shingle layers that have lost their granule coat on the south and west exposures. These aren't roofs waiting to fail. A lot of them already have, quietly, in ways that show up first as discoloration in an upstairs bedroom and get properly diagnosed six months later.
Beaver County sits north of the Pittsburgh metro, bordered by the Ohio River to the east and the West Virginia state line to the south. It's a county of older industrial towns, Beaver Falls, Aliquippa, Ambridge, and New Brighton among them, with significant residential density for our footprint. Washington County runs south and southwest from Allegheny County, covering the communities along I-79 and US-19 from the Pittsburgh suburbs down through Washington city and beyond. Greene County occupies the southwestern corner of Pennsylvania, sharing its entire southern and western border with West Virginia counties that are also in our territory. Waynesburg is the county seat, and the county is rural, hilly, and built on the same Appalachian plateau geology that shapes the surrounding region.
Each county has a dedicated page on this site covering the specific townships and boroughs we serve in that county, local permit information, and photos from recent jobs.
What Southwestern Pennsylvania Does to a Roof
All three counties fall in IECC Climate Zone 5A, the same classification as eastern Ohio, and the dominant roofing stress is the same: freeze-thaw cycling through winter months when temperatures cross the freezing point repeatedly, often multiple times in a single week. Every crossing is an opportunity for water that has worked its way under a shingle through a compromised seal or a missing nail to freeze, expand, and open the gap wider. The damage is slow and cumulative and invisible until it isn't. A Zone 5A roof that was installed correctly and maintained will hold up. One that had corners cut at installation will show you why those corners mattered, usually around year eight or ten.
Hail is a regular event in southwestern Pennsylvania, and the NWS Pittsburgh office, which covers all three of our PA counties, records storm events here every season. Greene County in particular sees consistent activity: Waynesburg, Dilliner, and Spraggs all appeared in 2025 hail event records, and Washington County has the same pattern. The damage accumulates across multiple moderate events before any single storm qualifies as a clear insurance claim, which means roofs here are often significantly degraded by the time a homeowner realizes the granule loss has crossed a meaningful threshold. Steel roofing panels carry a Class 4 impact resistance rating, the highest available, and some PA insurers discount premiums for homes with a Class 4 roof. It's worth asking your carrier before you choose a material.
The river valleys here compound the weather stress in ways that matter specifically to roofing. The Monongahela runs through the eastern edge of Washington County before joining the Allegheny in Pittsburgh. The Ohio River defines Beaver County's eastern border. These corridors hold humidity longer than the surrounding ridgelines and uplands, and in the low-lying areas along them, algae and moss colonize north-facing and shaded roof surfaces faster than the same material would degrade on a home sitting 200 feet higher on a ridge. Greene County's valley terrain, the Chestnut Ridge to the east, the West Virginia plateau to the south, creates similar conditions across most of its residential areas. Metal roofing doesn't support biological growth the way asphalt does, and standing seam steel is worth a direct comparison for any home in this kind of terrain.
What Our Customers Say
Permits and Licensing in Pennsylvania
Pennsylvania does not issue a state roofing contractor license. The state-level credential that matters for residential work is HIC registration: the Home Improvement Contractor registration issued by the Pennsylvania Office of Attorney General under the Home Improvement Consumer Protection Act. Any contractor doing more than $5,000 of home improvement work per year in Pennsylvania is required to carry this registration, and the registration number must appear in all advertisements, contracts, estimates, and proposals. Our PA HIC registration number is available on request and appears on every document we give you.
The registration requirement exists because Pennsylvania's AG office uses it as an enforcement mechanism against unlicensed and fraudulent contractors, and the law gives homeowners meaningful legal recourse when a contractor fails to register or comply. If a contractor working in Beaver, Washington, or Greene County can't produce a PA HIC registration number, that's a disqualifying fact, not a minor administrative detail.
Permits work at the local level in Pennsylvania, just as they do in Ohio. The specific requirement depends on your borough, township, or municipality, not the county. Most PA jurisdictions require a permit for a full replacement. We confirm what's required for your exact address before any project begins, pull the permit where one is needed, and manage any required inspections through completion. Each county page on this site lists local permitting contacts.
What We Do
Roof Replacement
We replace asphalt and steel roofs as a complete system, underlayment through ridge cap, built to GAF and Owens Corning spec for the Ohio River valley's freeze-thaw winters. Most asphalt jobs finish in one to two days.
Metal Roofing
Standing seam and exposed-fastener steel suited to northern West Virginia's humidity and ridge-top wind, with a 40-to-70-year lifespan and a Class 4 impact rating. It resists the algae growth that shortens shingle life in the river valley.
Seamless Gutters
Aluminum gutters cut on-site to your home's exact dimensions, with no joints to separate and leak. Gutter guards available for properties under heavy tree cover.
Roof Repair & Storm Damage
From a single leak to full hail or wind damage, we find the real source, document everything your adjuster needs, and make the repair across all 10 WV counties. West Virginia's claim window is generally one year from the date of loss, so call early. Active leaks get same-visit tarping.

How a Project Works
Free Inspection
You call or submit online, and we schedule a free inspection at your home, almost always within the same week regardless of which county you’re in. Our inspector gets on the roof, documents what he finds with photos and measurements, and walks you through every finding before leaving. You’ll know what the roof needs before any decisions are made, and the inspection costs nothing.
Written Estimate
The estimate breaks down materials, labor, permits, and cleanup as separate line items so you can see exactly what you’re paying for. We walk you through the product options, explain what actually differs between them, and help you choose what makes sense for your home and your situation. Financing is available for qualifying homeowners.
Installation
The crew arrives on the date you agreed on and works through the job. Standard residential replacements take one to two days depending on size, pitch, and how many old layers need to come off. Every component goes in to specification. That’s not language we use to sound thorough. It’s the thing that separates a roof that performs for 30 years from one that starts giving problems in eight.
Cleanup and Walkthrough
When the last shingle is in, the crew sweeps the yard, driveway, and landscaping with a magnetic roller to recover any fasteners that came down during the install, then runs a second pass before loading up. Then they walk the finished roof with you. You see the work before anyone leaves.
Warranty and Follow-Up
We register your manufacturer warranty before leaving and hand you all project documentation on the spot. We follow up after the job to confirm everything is performing. If something isn’t right, we fix it at no cost.
What Makes an Amish Crew Different
The men who run our crews didn’t take a roofing course. They came up building things from the time they were old enough to work alongside their fathers, in a community where construction is a core trade and where the quality of what you build reflects on you directly. That kind of training produces a different orientation to the work than you get from a crew assembled for the season and dispatched from a dispatcher board.
It shows in the specifics. The start time is early and consistent. Fasteners go in at the right angle and the right depth, not because a foreman is checking but because that’s the standard they hold themselves to. Flashing gets sealed the way the manufacturer specifies. When the roof is done, the cleanup gets the same attention as the installation: a magnetic roller goes through the yard and driveway twice to pick up any fasteners that came down, and the crew walks the finished roof with you before anyone leaves the property. None of that is policy we enforce from an office. It’s how these men work.
Every roof we install is backed by manufacturer warranties from GAF and Owens Corning and our own workmanship guarantee. We stand behind the work because we know how it was built.
