Penn Ohio Roofing
Roofing Contractor in Greenville, PA
A college town, a canal port, and a rail-shop borough — Greenville has the highest pre-1940 housing share in the Mercer Tier 2 set, and its roofs reflect it.
The Oldest Housing Stock in Mercer County's Tier 2 Set
Greenville's identity comes from three overlapping histories — a Shenango Canal port from the 1830s, a Bessemer and Lake Erie Railroad shop town from the late 19th century, and a college town since Thiel College was chartered in 1866. The practical consequence for a roofer is that the housing stock is old. ACS 2020–2024 5-Year figures put pre-1940 share at about 47%, the highest of any Tier 2 city in our territory, and median year built at 1943. Median home value is around $115,100 and median household income around $52,660 — a college-town profile with a durable owner-occupancy base and a real, if smaller, student-rental share around the Thiel campus.
What a Greenville Roof Actually Is
The blocks around Main Street, downtown Greenville, and the Thiel campus are dense pre-1940 frame and brick homes — Foursquares, late-Victorian two-and-a- half stories, and worker cottages, most of them on original 1x6 plank decking. Pitches run 10/12 and steeper on the two-story stock and 8/12 on the bungalows. Every one of those roofs needs roof jacks and staging, and we plan for 5 to 15 percent deck replacement on tear-off, most often around vent stacks, valleys, and eaves. Masonry chimneys are near-universal on the pre-1940 blocks and their counter-flashing was set into mortar rather than caulked to brick — we grind the old flashing out, tuckpoint if the mortar has spalled, and re-set into fresh mortar before the new roof flashing goes on.
The Lake-Effect Edge
Greenville sits about 15 miles further north-northwest than Sharon, which puts it deeper into the lake-effect snow bands that come off Lake Erie. The 1985 F5 tornado tracked well south of Greenville through Wheatland–Hermitage, so the benchmark severe-weather event is a valley event rather than a direct one. What we see more of in Greenville than in Sharon is ice damming on the pre-1940 steep-pitch roofs — a ventilation and insulation problem as much as a shingle problem. On many Greenville re-roofs the ridge-vent cut-in, cleared soffit intake, and adequate attic insulation is as much of the payoff over 25 years as the new shingle itself.
Overlay Is Not the Move Here
A meaningful share of Greenville's pre-1940 roofs are already on their second or third layer, with visible slate nail holes still in the plank sheathing under the current asphalt. A third layer of asphalt is not a good idea structurally on plank decking, and it disqualifies the roof from GAF Golden Pledge warranty coverage. Tear-off, financed on our 0% short-term or long-term programs, is the recommendation on almost every Greenville full replacement.

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.

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 — Greenville
- How is a Greenville roof different from a Sharon roof?
- Greenville has a higher pre-1940 concentration than Sharon does — Census figures put roughly 47% of Greenville's housing at pre-1940 construction versus about 39% in Sharon. That means the Sharon-style plank-decking, steep-pitch, masonry-chimney job profile is actually more common in Greenville, especially in the blocks around Main Street and Thiel College. The difference is the drive — Greenville is about 20 minutes from our Sharon shop.
- Do you work around Thiel College and downtown Greenville?
- Yes. The blocks immediately around Thiel and the downtown Main Street corridor are heavily pre-1940 frame and brick homes. Many are on original plank decking with masonry chimneys and second- or third-generation asphalt roofs. Overlay is not an option we recommend on those homes.
- Who issues permits in Greenville, PA?
- The Borough of Greenville code office at Borough Hall. Contractor registration policy and current contact should be re-verified before each job. We handle the permit paperwork as part of every full replacement in 16125.
- Do the ice dams I keep getting mean I need a new roof?
- Not necessarily. Greenville sits far enough north to catch more lake-effect snow than Sharon or Hermitage, and ice damming on a pre-1940 Greenville home is usually a ventilation and insulation problem before it is a shingle problem. A ridge-vent cut-in with cleared soffit intake and adequate attic insulation solves most cases without a full replacement — we walk through both options in the estimate.
- How long does a full replacement take on a Greenville pre-1940 home?
- Two to three days on the roof for the typical steep-pitch, plank-decked Greenville home with a masonry chimney and hip-and-valley geometry — closer to a Sharon Victorian in labor than to a Hermitage ranch. We do not leave a Greenville roof open overnight; if weather changes we dry it in.
