We’ve been climbing Greensburg roofs since 1984. We know the difference between a 1920s brick colonial on Maple Avenue with original Pennsylvania slate and a post-war ranch off Route 130 with its first asphalt overlay. That matters. The wrong crew treats them the same and misses what’s underneath.
Greensburg sits at roughly 1,000-1,100 feet in the Laurel Highlands foothills, meaningfully higher than Pittsburgh 30 miles west. Your roof absorbs substantially more freeze-thaw cycling, ice dam pressure, and seasonal snow load than the metro area roofers most companies also serve. The slate-roofing tradition that came with early-20th-century coal-and-steel prosperity left Greensburg with a large share of homes that either still carry original Pennsylvania slate or have had asphalt overlaid on top of skip-sheathing designed for slate. A hidden deck condition that catches out-of-town crews off guard.

We recently repaired a flashing failure on a 1920s brick colonial on Maple Avenue where original Pennsylvania slate had been overlaid with asphalt without re-decking, leaving skip sheathing gaps that trapped moisture and rotted the valley flashing. Our crew removed the affected slate, installed new copper flashing with proper ice-and-water shield extending 6 feet up the deck, and patched the asphalt shingles with matching Owens Corning Duration. Done right. And if it hadn’t been, we would have made it right.
Our Roof Repair Services in Greensburg
Leak Repair
Leaks in Greensburg homes rarely come from a single obvious hole. More often, they’re the slow result of ice dam backup at the eaves, failed vent boots on a 1940s foursquare, or water finding its way through skip-sheathing gaps where asphalt meets original slate. We trace the stain back to the source, photograph the path, and fix what caused it. Not just the symptom.
Most Greensburg leak repairs run $180-$450. If we find deck rot beneath, we’ll show you the photos and explain whether a partial tear-off makes more sense than another patch. A square deal: the price we quote is the price you pay.
Flashing Repair
Flashing is where most Greensburg roofs eventually fail. Copper and galvanized step flashing on chimney-slate intersections corrodes over decades. Valley flashing on homes near 15601 and 15605 ZIP codes takes punishment from snow load and freeze-thaw that lower-elevation Pittsburgh roofs simply don’t see.
We stock copper, aluminum, and lead-coat flashing for repairs on historic homes. A typical flashing repair in Greensburg runs $250-$650. We install proper ice-and-water shield behind every piece, extending 6 feet up the deck in valleys. That’s not an upgrade here. It’s the local standard.
Valley Repair
Open valleys on older Greensburg homes collect debris, hold snow, and channel the meltwater that feeds ice dams. Closed valleys on newer overlays often trap moisture where asphalt meets uneven slate substrate. We repair both types, matching the original architecture while upgrading the waterproofing.
Valley work on a Greensburg home typically runs $400-$850. If your ridge has developed a subtle bow from historic coal mine subsidence, we’ll flag it before we lay new material. Covering a structural issue with shingles doesn’t fix it. We won’t do it.
Shingle Replacement
Wind and hail damage, plus the natural aging of 20- to 30-year asphalt overlays, leave Greensburg homeowners with missing or cracked shingles. We match existing shingles from GAF, CertainTeed, and Owens Corning lines, or Atlas and Tamko when the original spec calls for it. No substitutions without your say-so.
Spot shingle replacement in Greensburg runs $150-$350 per area. If your home has asphalt over skip sheathing, we’ll inspect beneath before we nail anything down. Gaps in that old wood decking accelerate rot. Sometimes a full tear-off is the honest recommendation.
Flat Roof Patch
Flat sections on Greensburg’s older commercial buildings and some residential additions need different materials and techniques. We patch EPDM, TPO, and modified bitumen with manufacturer-authorized materials. Most flat patches run $300-$600 and carry the same 90-Day Done Right Promise as our pitched-roof work.
Vent Boot Repair
Cracked rubber vent boots are a common leak source on 1950s-era Greensburg ranches. We replace with properly sized boots and seal with ice-and-water shield at the base. Simple work, but done wrong it leaks again in two years. We do it once. Typical cost: $120-$220.

Common Roof Repair Problems We See in Greensburg Homes
- Ice dam damage at eaves and valleys. Greensburg’s elevation forces orographic lift on northeast-tracking storms, delivering higher snowfall and more freeze-thaw events than Pittsburgh. Without ice-and-water shield on the lower 3-6 feet of deck, meltwater backs up under shingles and rots the sheathing.
- Concealed deck rot from asphalt over skip sheathing. Many 1910s-1950s homes in 15601 and 15606 were built with wood skip sheathing for original slate. Later asphalt overlays left gaps that trap moisture. The shingles look fine. The deck beneath is mush.
- Structural sag from historic coal mine subsidence. Westmoreland County’s deep mining legacy means some roof planes are no longer truly flat. A bowed ridge line isn’t always rafter failure, but it’s a red flag that must be identified before new shingles go on.
- Failed flashing at chimney and valley intersections. Original copper on coal-era homes eventually fatigues. Galvanized replacements from the 1970s rust through. Water follows the path of least resistance, often appearing far from where the actual failure sits.

FAQs - Roof Repair in Greensburg
Sometimes, but we need to inspect first. If the leak traces to localized flashing failure and the skip sheathing beneath is sound, we can remove a section of asphalt, repair the underlying slate and flashing, and patch back with matching shingles. If deck rot has spread through the gaps in skip sheathing, a partial tear-off is the honest fix. Call (844) 563-1816 and we’ll show you exactly what we’re seeing.
Greensburg’s 1,000-1,100 foot elevation means measurably more snowfall and freeze-thaw cycling than Pittsburgh 30 miles west. Ice damming at eaves and valleys is a recurring seasonal failure mode here, which is why we install ice-and-water shield on the lower 3-6 feet of deck as standard practice, not an upgrade. If your current roof lacks this protection, you’re carrying unnecessary risk every winter.
Yes. Westmoreland County’s deep coal mining history means some homes have experienced minor subsidence over decades. We’ve found roof planes that are no longer truly flat, with ridge lines that have developed a subtle bow or sag unrelated to rafter failure. This must be identified before new shingles are laid. Covering it doesn’t fix it. We flag it, explain it, and address the underlying issue.
Extensively. It’s common in Greensburg’s 15601 and 15605 ZIP codes. The key challenge is the skip sheathing beneath, designed for slate’s weight and fastening pattern, not asphalt’s. Gaps trap moisture. Nails don’t always bite. We know how to remove sections without destabilizing the remaining slate, repair the decking where needed, and integrate new materials properly. Not every crew understands this hybrid construction.
We carry copper, lead-coat, and aluminum flashing from GAF and Owens Corning, with Atlas and Tamko accessories for color-matched repairs. For historic homes with original Pennsylvania slate, we often specify copper for longevity and compatibility. We stock locally for same-day and next-day turnaround on most Greensburg jobs. Call (844) 563-1816 to confirm availability for your specific repair.
