Penn Ohio Roofing
Roofing Contractor in Washington County, PA
Mon Valley borough housing on steep river hillsides, plus high-growth suburban colonials along the I-79 corridor in Peters and North Strabane.
Economic History
Washington County was created in 1781 and was the center of the Whiskey Rebellion of 1794. Coal defined the next two centuries — the Pittsburgh coal seam runs beneath most of the county — along with river-town glass and steel at Charleroi, Donora, and Monongahela. Donora is remembered nationally for the 1948 smog disaster that helped drive federal clean-air legislation. Since 2008 Marcellus Shale drilling and midstream construction have reshaped the county's economy, and the northern townships along I-79 (Peters, Cecil, North Strabane) have become high-growth Pittsburgh suburbs with substantial new-construction housing.
Housing Stock Across Washington County
The Mon Valley boroughs — Charleroi, Donora, Monongahela — are dense pre-1940 stock on steep river hillsides, with masonry rowhouses, plank decking, and many roofs carrying a second or third layer. The city of Washington mixes Victorian-era homes near the courthouse with postwar neighborhoods. Peters Township and Canonsburg's outskirts are 1990s-and-newer colonials with steep hip-and-valley roofs, big front gables, and attached-garage tie-ins that make flashing detail the critical work.
Permitting Norms
Permits are issued by each municipality under the Pennsylvania Uniform Construction Code, with the growth townships (Peters, North Strabane, Cecil) running active code offices and requiring permits and inspections on re-roofs. HICPA registration with the Pennsylvania Attorney General is required for all home improvement contractors.

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.

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
- How far is Washington County from your Sharon shop?
- Canonsburg and Peters Township run about 75-85 minutes and the Mon Valley boroughs about 90. We route the county in planned blocks rather than one-off trips, which keeps pricing sane.
- Do Peters Township and North Strabane require re-roof permits?
- Both run active code offices under the Pennsylvania Uniform Construction Code and generally require a permit and inspection on a full tear-off. We pull it as part of the job.
- Why are the Mon Valley roofs different from Peters Township roofs?
- Different eras entirely. Charleroi, Donora, and Monongahela are pre-1940 hillside stock with plank decking and multiple layers; Peters is 1990s-and-newer colonials with steep hip-and-valley geometry and garage tie-ins where flashing detail decides the outcome.
- Do you handle hail claims in Washington County?
- Yes. Hail and heavy summer rain from squall lines crossing the Ohio Valley drive most claims here, and we attend the adjuster inspection so scope gets settled on the roof.
Customer Reviews
What Our Customers Are Saying in Washington 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
