Greensburg sits higher than most contractors expect. At 1,000-1,100 feet in the Laurel Highlands foothills, your roof endures freeze-thaw cycles, ice dam pressure, and snow loads that Pittsburgh roofs 30 miles west simply don’t face. The coal-boom housing stock built between the 1910s and 1950s - foursquares on Harvey Avenue, brick colonials near St. Clair Park, craftsman bungalows off Maple Avenue - carries legacy conditions we’ve learned to read. Original Pennsylvania slate. Wood skip sheathing. Asphalt overlays hiding rot. We’ve seen what happens when a crew from the flatlands misses these signs.
We don’t chase storms. We’re here year-round, with local crews who live in the same ZIP codes they work: 15601, 15605, 15606. When you call, you speak to a live person, not a voicemail tree. When we schedule, we show up. That’s how Ridgeline Roofing Co. has operated since 1984.
Why Ridgeline Roofing Co. Is Greensburg’s Preferred Specialty Roofing Company
We’ve been standing behind local roofs for over 42 years. Not every contractor serving Greensburg can say the same. The storm-chasing outfits roll through after hail events, hand out flyers at the Westmoreland Mall, and vanish before the shingles curl. We hire apprentices from Westmoreland County, train them into journeymen, and plan to be here in thirty years.
Our 90-Day Done Right Promise means what it says: if it’s not right, we come back and make it right. No paperwork to file, no argument, no runaround. The number on your estimate is the number on your invoice. A square deal, plain and simple.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof - not a scary speech in your driveway. We install products from seven manufacturer lines, including GAF, CertainTeed, and Owens Corning, with no substitutions. And a live person answers our phones around the clock, including the middle of a February ice storm when your valley starts leaking into the kitchen - exactly the situation our Emergency & Storm Damage in Greensburg team is ready for.
Our Specialty Roofing Services in Greensburg
Modified Bitumen Roofing
Modified bitumen is our go-to for low-slope sections on older Greensburg homes - rear additions over kitchens, porches on bungalows near Lynch Field, garage roofs that were never built to the same pitch as the main house. The APP-modified membranes we install stand up to the Laurel Highlands’ temperature swings better than standard asphalt. At elevation, the freeze-thaw cycling is relentless; modified bitumen’s flexibility prevents the cracking you see on cheaper roll-roofing jobs after three winters. We torch-apply or cold-adhere depending on the substrate, and we always inspect what’s underneath first. In Greensburg, that substrate is often skip sheathing or plank decking that needs attention before any membrane goes down.
Built-Up Roofing (BUR)
Built-up roofing remains a sound choice for flat commercial roofs and certain residential applications in Greensburg’s historic districts - think the converted mixed-use buildings along Main Street, or the older apartment blocks near the courthouse. Multiple layers of bitumen and reinforcing fabric create a redundant system that tolerates the ponding and thermal movement common to our climate. We specify coal-tar pitch or asphalt BUR based on the existing structure and drainage. The key detail in Greensburg is proper installation of the base sheet over whatever deck exists; we’ve found too many BUR failures trace back to crews who laid new over old without addressing the skip sheathing or subsidence-related low spots underneath.
EPDM Roofing
EPDM rubber roofing suits Greensburg’s low-slope and flat applications where a single-ply system makes sense - modern additions, commercial buildings, or residential retrofits where weight is a concern. The black membrane absorbs heat to shed snow load faster, which matters at our elevation where snow sits longer than in Pittsburgh. We mechanically attach or fully adhere based on wind exposure and building height, and we always detail the seams and penetrations with the care this material demands. EPDM’s longevity is proven, but only when installed by technicians who understand that Greensburg’s temperature swings stress every seam. Our crews do.
Solar Ready Roofing
Solar ready roofing in Greensburg means more than leaving space for panels. It means engineering the deck and underlayment to handle both our snow loads and the penetrations that come with rack-mounted systems. We work with homeowners who are planning ahead - often the same 55-75 demographic who intends to stay in their house for the next twenty years. The roof we install today needs to outlast the solar lease. That starts with proper sheathing, not skip boards, and an ice-and-water shield regimen that accounts for the freeze-thaw reality at 1,000 feet. We coordinate with your solar installer, or we can recommend local partners we’ve worked with before.
TPO Roofing & Green Roof Systems
TPO’s white reflective surface suits certain commercial applications in Greensburg, particularly where cooling costs drive the specification. We install mechanically attached and adhered systems from authorized product lines. Green roof systems are less common in our market but appropriate for specific flat-roof applications - we consult on structural load, drainage, and the waterproofing layer that must perform flawlessly before any growing medium goes down. Both systems demand the same local knowledge: what’s under the membrane, and how has this building moved over the decades?

Common Specialty Roofing Problems We See in Greensburg Homes
- Ice-dam damage at eaves and valleys. Greensburg’s elevation forces orographic lift on northeast-tracking storms, delivering more snow and freeze-thaw events than Pittsburgh. Without proper ice-and-water shield at the lower deck, water backs up behind shingles and rots the sheathing. We see this every March.
- Skip sheathing rot under asphalt overlays. When coal-boom homes got asphalt shingles over original slate, the gaps in wood skip sheathing trapped moisture. The deck rots from underneath while the shingles look fine from the street. Only a full tear-off reveals the truth.
- Subsidence-related roof plane distortion. Westmoreland County’s deep mining history means some Greensburg homes have settled subtly over decades. Ridge lines develop a bow. The plane isn’t flat. New shingles laid over this simply telegraph the problem and fail early. We measure before we quote.
- Improper underlayment for the elevation. Crews accustomed to Pittsburgh’s milder conditions install standard felt and call it done. In Greensburg, that’s a leak waiting to happen. Our local standard - full ice-and-water shield at eaves and valleys - is not an upgrade. It’s the baseline.

We recently worked on a 1920s craftsman bungalow on Maple Avenue where the original Pennsylvania slate had been overlaid with asphalt; the skip sheathing underneath had rotted in two valleys from repeated ice damming. We fully tore off the old layers, replaced the deck with OSB, and completed a Roof Replacement & Installation in Greensburg using CertainTeed Landmark shingles with a full ice-and-water shield at the eaves to meet local standards. The homeowner had lived there thirty-two years. She plans to stay.

FAQs - Specialty Roofing in Greensburg
You’re 300-400 feet higher, and that elevation difference matters. Greensburg’s orographic lift traps more snow and sustains longer freeze-thaw cycles than Pittsburgh’s river valley climate. Your roof spends more days with snow melting at the ridge, running down, and refreezing at the colder eaves. The fix isn’t better shingles; it’s proper ice-and-water shield installation at the lower 3-6 feet of deck and adequate attic ventilation. Call (844) 563-1816 - we’ll inspect and show you exactly what’s happening.
Yes, if the deck underneath is sound and the surrounding slates are secure. We source matching Pennsylvania slate and replace individual slates with copper nails, not screws. However, we always inspect the skip sheathing and flashings first. In Greensburg, we’ve found that “just a few broken slates” often reveals the larger issue: the underlying wood has rotted from ice damming, or previous asphalt overlays have compromised the deck. We photograph everything and give you the full picture before we quote.
In Greensburg, asphalt-over-slate almost always requires full tear-off. The skip sheathing beneath was never designed for the weight or fastening pattern of asphalt shingles, and the gaps trap moisture that rots the wood. A third layer - new shingles over old - compounds the problem and masks the decay. We remove everything to the rafters, replace with solid OSB decking, and install a system built for your roof’s actual conditions. When less extensive work is needed, our Roof Repair - Greensburg crews handle targeted fixes with the same thoroughness. Call for a free inspection; we’ll show you what we’re seeing.
For low-slope and flat applications in Greensburg, modified bitumen and properly installed EPDM outperform standard asphalt in freeze-thaw resilience. Modified bitumen’s APP or SBS modifiers maintain flexibility at low temperatures. EPDM’s seam technology, when executed correctly, handles thermal expansion without the cracking you see in cheaper systems. On pitched roofs, we specify architectural-grade asphalt from CertainTeed or GAF with full ice-and-water shield - never three-tab shingles at this elevation. The material matters, but the installation detail matters more.
Yes. We install solar-ready roofing systems in Greensburg and have consulted on green roof applications for appropriate flat-roof structures. Solar-ready work requires coordination on structural load, penetration sealing, and underlayment selection for our snow-load conditions. Green roofs demand flawless waterproofing before any growing medium goes down. Both are within our capability, and both benefit from the same local knowledge: understanding what’s under the membrane, and how this building has behaved over decades.
