Penn Ohio Roofing
Roofing Contractor in Allegheny County, PA
Steel-era hillside housing, slate-legacy roofs in the older suburbs, and modern tear-off-and-replace work across the North and South Hills.
Economic History
Allegheny County was carved out of Westmoreland and Washington counties in 1788 at the forks of the Ohio, and its history is the history of American steel: Carnegie's mills along the Monongahela, the Homestead and Braddock works, and the rail and river network that fed them. The industry's collapse between 1979 and 1985 cost the region well over a hundred thousand manufacturing jobs and emptied the mill boroughs. Pittsburgh's rebuild since then has run on hospitals, universities, banking, and robotics, and the county's housing market now splits between restored city neighborhoods and the North Hills and South Hills suburbs.
Housing Stock Across Allegheny County
Roofing work here is defined by age and slope. Pittsburgh's city neighborhoods and the river boroughs hold enormous inventories of 1890-1930 frame and brick houses on narrow hillside lots - steep gables, plank decking, third-story dormers, slate and asphalt over slate, and almost no room to stage a dumpster. Mt Lebanon, Sewickley, and Fox Chapel add large Tudor and Colonial Revival homes where slate and tile repair still comes up. McCandless, Pine, Moon, and Monroeville are postwar-through-1990s ranches, split-levels, and colonials that take conventional architectural-shingle tear-offs.
Permitting Norms
Permits are issued municipality by municipality under the Pennsylvania Uniform Construction Code, and every home improvement contractor working in the state must hold an active HICPA registration with the Pennsylvania Attorney General. Pittsburgh's Department of Permits, Licenses and Inspections requires a permit for re-roofing and enforces contractor licensing within city limits, and the larger municipalities such as Mt Lebanon, Monroeville, and Moon Township run their own code offices.

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
- Do you need a permit to replace a roof in Pittsburgh?
- Inside city limits, yes - the Department of Permits, Licenses and Inspections requires a re-roof permit and expects the contractor to be registered with the city. Suburban municipalities each set their own rule, and we pull whatever the local code office requires before the crew arrives.
- Our house still has slate. Can you work on it?
- We can repair and tie into slate and we can replace it with a modern system. What we will not do is quote a slate roof sight-unseen; the framing, the deck boards, and the condition of the flashing decide the job, so we get on the roof first.
- How do you stage work on a narrow city lot?
- Smaller dumpsters placed with a permit where the street requires one, ground protection over walks and plantings, and staged tear-off so the deck is never left open overnight. On the tightest lots we load out by hand rather than damage the neighbor's property.
- Why do so many Pittsburgh roofs have ice dam damage?
- The old stock pairs steep main roofs with nearly flat porch and rear-addition roofs, and those low-slope sections sit under snow that melts off the warm section above. Wide ice-and-water shield and balanced attic ventilation are what actually fix it.
Customer Reviews
What Our Customers Are Saying in Allegheny 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
