Big River Roofing is based at 2404 E State St in Hermitage, PA, and our service area covers most of northwestern and western Pennsylvania. From the Shenango Valley down through the I-79 corridor and east into the Slippery Rock watershed, we install and repair roofs, gutters, and siding for homeowners across four counties.
Our greater service area includes the Shenango Valley, the Beaver Valley, the northern Pittsburgh suburbs, and the rural communities along PA-58, PA-18, and US-422. You might also hear this region called the Mercer-Butler-Lawrence corridor, the Pittsburgh North region, or simply Western PA. Whatever you call it, this is our home, and it is where we have spent the last five years earning our four-time Best of the Best recognition.
Western Pennsylvania weather is not gentle. The National Weather Service tracks an average of around 40 inches of snow per year across the Pittsburgh region, with temperature swings that push the freeze-thaw cycle hard from November through March. Spring brings strong wind events and occasional hail. Summer brings UV exposure and afternoon thunderstorms. A roof in Mercer County faces all of that, every year.
A local roofer knows what that weather does to a roof and builds the installation accordingly. Flashing tight enough for milder climates pulls loose here by year 15. Shortcuts on ice and water shields show up as leaks during the first hard winter. We have seen the failure patterns specific to this region, and we install them to prevent them.
Being local also means we are still here when something needs attention. Storm-chasing contractors who swing through after a hail event and disappear are not an option when your roof has a problem three years later. Our office is on East State Street, Don grew up in Hermitage, and we plan to be here for a long time.

Mercer County is the heart of our service area and the county we know best. This is where our office is located, where the majority of our crews live, and where the bulk of our work happens.
We do regular work in New Castle, Neshannock, Ellwood City, and the smaller communities along US-422 and PA-65. Storm damage is common here, especially following spring and summer wind events.
Butler County is the largest and most populous of our service area counties, stretching from the rural northern townships near Slippery Rock down to the fast-growing northern Pittsburgh suburbs around Cranberry Township.
Beaver County’s terrain along the river means homes are often on slopes, with complicated access for roofing crews and demanding drainage needs. Poorly installed gutters can cause foundation problems fast.
Most Cranberry homes have original roofs that are now 20 to 25 years old, which is exactly when architectural shingle roofs start showing their age. We do a high volume of roof replacement work in Cranberry Township.
Roofing historic buildings in Harmony requires a different approach than newer homes. We respect the architectural character of Harmony building and choose materials and colors that fit the home’s period.
Many Wexford homes have complex roof designs, with multiple gables, tall peaks, steep pitches, and multiple chimneys. That complexity makes installation quality matter more than on a simple ranch
The rental-heavy nature of parts of Slippery Rock means we see a lot of investment property owners who want cost-effective roofing that meets code and protects the building without premium upgrades.
Older Butler homes often have roof structures that were not designed for the heavier asphalt shingles common today. When we inspect a home built before 1960, we pay particular attention to the decking, rafters, and sheathing to make sure the structure can carry modern roofing materials.
Roofing older homes in Beaver borough requires attention to the architectural character of each building. Many of the homes have steep roof pitches, complex geometry, and original details that should be preserved or respected when considering a new roof installation.
Grove City’s open terrain means wind exposure is a factor, and we see regular storm damage roofing calls after spring and summer wind events. The housing stock is a mix, but architectural shingles are the most common new install, with some metal roofing on larger rural properties.
Many New Castle homes have been through multiple roof generations, and older installations sometimes have structural issues that need to be addressed before a new roof goes on. We check the decking and framing carefully during our inspections on older homes.
Housing in Neshannock ranges from 1960s ranches to newer construction built over the last 20 years. Most of our Neshannock work is architectural shingle replacement on homes that have reached the end of their original roof life and occasional repairs.
Roofing in the borough of Mercer often means working on older homes with complex geometry, original details, and sometimes original slate or metal elements. We approach these homes with care, choosing materials & colors that fit the architectural period.
Sharon is the largest city in Mercer County and one of our highest-volume service areas. We do regular roof repair, installation, and replacement work across the city, on homes ranging from small bungalows to larger Victorian-era residences.
Hermitage’s housing stock is diverse: older buildings near downtown and along the Sharon border, larger mid-century areas, and newer construction. We work on all of it, every week. Hermitage is where our Best of the Best recognition comes from.
Many Ellwood City homes have complex roof geometry, multiple dormers, and chimneys that require careful flashing work during any roof project. Our installs use new flashing at every transition, which is particularly important on older homes.
West Middlesex sits along I-80, exposing it to wind patterns that come across the interstate corridor. Homes near the highway face more wind exposure than those in sheltered locations, and proper shingle nailing and flashing matter more as a result.
When inspecting older Beaver Falls homes, we pay attention to the decking, ventilation, and flashing. Decades of freeze-thaw cycles on under-ventilated attics can lead to rot that is not visible until the tear-off. We plan for that during quotes to avoid surprises.
Most Warrendale home roofs are now 20-30 years old, which is when shingle roofs from that era start to need replacement. We consistently do roof replacement work in the area, typically on homes with complex geometry and moderate-to-high pitches.
Homeowners and HOA boards across Western Pennsylvania describe Big River Roofing as honest, on time and easy to work with, from the first estimate to the final cleanup. Reviewers often name sales pros Jeramey Norton and Patrick Conors and owner Don Kovac for clear communication and fair pricing, and several mention storm damage jobs and full roof and gutter replacements finished in a day or two. Many point out how clean the crew leaves the property.
