Penn Ohio Roofing
Roofing Contractor in Butler County, PA
Two very different roofing markets in one county: pre-1940 borough and city stock around Butler, Zelienople, and Harmony, and steep-pitch modern colonials across the Cranberry and Mars growth corridor.
Economic History
Butler County was created in 1800 out of Allegheny County and grew first on farming, then on oil, glass, and railcar manufacturing. The city of Butler became a company town of sorts around the Standard Steel Car Company and later Pullman-Standard, and the American Austin/Bantam works there produced the prototype that became the wartime Jeep. Zelienople and Harmony trace to the Harmony Society, a German pietist communal settlement founded in 1804 — a history that still shapes the historic districts in both boroughs. Since the 1980s the county's economy has tilted south: Cranberry Township turned from farmland into one of Pennsylvania's fastest-growing suburbs at the junction of I-79 and the PA Turnpike, drawing corporate offices, medical campuses, and large-lot subdivision housing.
Housing Stock Across Butler County
The county splits three ways for roofing purposes. Butler city and the older boroughs (Evans City, Harmony, Zelienople, Saxonburg) hold dense pre-1940 stock — steep-pitch gables, plank decking, slate and asphalt-over-slate, and narrow side yards that complicate staging. Cranberry, Mars, and Adams Township are dominated by 1990s-and-newer two-story colonials with complex hip-and-valley geometry, front-facing gable stacks, and 8/12-plus pitches. The rural north around Slippery Rock is farmhouses, metal-roofed outbuildings, and postwar ranches.
Permitting Norms
Permits are issued at the municipality level under the Pennsylvania Uniform Construction Code — Cranberry Township and the City of Butler run their own code offices, while many smaller boroughs and townships use a third-party code agency. Re-roof permits and inspections are common in the growth municipalities and less consistently required in the rural townships. Statewide HICPA registration with the Pennsylvania Attorney General applies to every home improvement contractor working here.

Regional climate — Shenango Valley & the PA/OH border
This is a regional pattern, not a local one — it holds across our whole territory. Roughly 40 inches of rain and 50+ inches of snow a year, with lake-effect bands off Lake Erie in winter. Freeze-thaw is the dominant cool-season roof stressor from November through March. Summer brings straight-line wind events off the Ohio border and occasional hail from convective thunderstorm lines. What varies from town to town is which of those forces bites first on the specific roof profile that town was built for — that's what the page above covers.
Manufacturer credentials
- GAF Master Elite Contractor. Held by a small percentage of roofing contractors nationwide. Required to install the GAF Golden Pledge warranty — 50 years on materials, 25 years on workmanship, transferable once. GAF inspects the completed roof before issuing the warranty.
- Owens Corning Preferred Contractor.

- Fully insured in Pennsylvania and Ohio. In-house crews — no subcontractors. Family-owned and operating out of Sharon, PA since 2000.
Path 1 — Insurance claim
For wind, hail, or storm-driven damage. We walk the roof with your insurance adjuster and document what we find so nothing that should be covered gets missed. We are not a public adjuster — that is a separate PA license — and we do not negotiate the settlement. We document damage, meet the adjuster, and rebuild what the carrier approves to code and to manufacturer spec.
Path 2 — Retail with financing
For roofs simply reaching the end of their life. 0% interest financing on shorter terms and long-term financing that keeps monthly payments low. Runs through a lending partner and is subject to credit approval. We walk through both paths in the free in-home estimate before you sign anything. See financing details →

Frequently Asked Questions
- Do you cover all of Butler County?
- Yes — from Slippery Rock in the north to Cranberry Township on the Allegheny County line. Butler is about 55 minutes from our Sharon shop and Cranberry about 70, and both sit inside our normal routing.
- Are re-roof permits required in Butler County?
- It depends on the municipality. Cranberry Township and the City of Butler run their own code offices under the Pennsylvania Uniform Construction Code and typically require a permit; several rural townships do not. We confirm before scheduling.
- Why do Cranberry roofs cost more than Butler city roofs of the same size?
- Geometry and access. Cranberry's 1990s-and-newer colonials carry 8/12-plus pitches with multiple hips, valleys, and dormers, so labor, valley metal, and staging all go up even when the square footage matches.
- Do you handle hail and wind claims in Butler County?
- Yes, including attending the adjuster's inspection so scope is settled on the roof. Summer squall lines out of the west are the most common source of claims in the southern part of the county.
Customer Reviews
What Our Customers Are Saying in Butler County
Penn-Ohio did good work at a very reasonable price. Other quotes were ~30% higher. Austin got us on the calendar quickly and the team replaces our roof in 6 hours.
Penn Ohio just recently replaced my roof. Removed all the old material down to bare wood, and replaced with beautiful new shingles. Cleaned up all the trash. Everything done in one day! My roof looks great. Thanks Penn Ohio!
I needed some wood and peak repairs done. Penn Ohio was quick to come and provide an estimate. Which was a very good estimate. The work was done with care and in one day. I'm very pleased with the work. They were also very easy to communicate with. I would strongly recommend.
I called Penn Ohio for a roof repair estimate on my home recently. Gary came to my home and I could tell that he cares about doing the best for the customer. He gave me a lot options to choose from and I felt very comfortable and not like he is trying to take advantage of me like other companies. 10/10 guy.
These guys were great to work with. I've dealt with contractors that want to spend two hours of my time hitting me with a PowerPoint followed by high pressure tactics to commit immediately. They offer one price if I sign today but magically
Great company to work with. Gary and his crew were great. They did a very nice job replacing the roof and gutters. The price was aggressive and the cleanup was excellent. Definitely recommend Gary and Dustin for your roofing needs
