Our Roof Replacement & Installation Services in Greensburg
Full Roof Replacement
Most Greensburg homes built between 1910 and 1950 carry original wood skip sheathing designed for heavy Pennsylvania slate. When asphalt shingles were laid over that skip sheathing decades later - often with gaps of a half-inch or more between boards - moisture found its way in, freeze-thaw cycling pried at the deck, and rot set in where nobody could see it. We pull the old roofing, inspect every inch of that deck, and replace compromised sheathing with full OSB before we install your new system. In Greensburg, a roof replacement that skips this step is a roof replacement that fails early. We see it every spring when the melt starts.
Asphalt Shingle Installation
GAF Timberline HDZ and CertainTeed Landmark shingles are the workhorses we install most often in Greensburg - proven performance at elevation, strong wind ratings for the gusts that come off Chestnut Ridge, and color palettes that respect the traditional character of Westmoreland County neighborhoods. A typical asphalt replacement on a Greensburg foursquare or colonial runs $8,500-$15,000 depending on deck condition, pitch complexity, and whether we need to rebuild valleys or dormer flashings. We always install Grace Ice & Water Shield from eave to six feet up the deck - non-negotiable in this freeze-thaw zone, not an upgrade we try to sell you.
Metal Roofing
Standing seam metal roofing has gained real traction in Greensburg among homeowners who intend to stay put for decades. At $14,000-$28,000 installed, it’s a significant investment, but one that sheds snow loads better than any shingle, laughs at ice dam pressure, and carries a lifespan that outlasts most mortgages. We install 24-gauge steel systems with concealed fasteners - no exposed screws to back out after fifteen winters. Metal’s especially suited to Greensburg’s steeper pitches and to homeowners who’ve already replaced one asphalt roof and don’t care to do it again.
New Construction Roofing
For new builds in Greensburg and the developing areas toward Murrysville, we install complete roofing systems from sheathing up, working with your builder’s timeline and coordinating inspections with Westmoreland County. We spec the right underlayment, ventilation, and flashing details for your roof pitch and orientation - details that prevent callbacks and protect your builder’s reputation. Same standards, same photo documentation, same 90-Day Done Right Promise.

Trusted Brands We Service in Greensburg
We maintain dealer status with GAF, CertainTeed, and Owens Corning - three of the seven manufacturer lines we install - and we stock common accessories and repair components so Greensburg homeowners aren’t waiting weeks for special orders. When we specify a GAF System Plus warranty or a CertainTeed Integrity Roof System, every component comes from that manufacturer, installed to their spec, registered properly. No mixing brands to save a few dollars. No shortcuts on starter strips, ridge caps, or ventilation that void your warranty before the first snowfall.
Common Roof Replacement & Installation Problems We See in Greensburg Homes
- Skip-sheathing rot under asphalt overlays. The gaps in original wood skip sheathing trap moisture against asphalt shingles installed without full re-decking. By the time you see a ceiling stain in your Greensburg home, the deck may be compromised across multiple rafter bays. We find this in perhaps one-third of the tear-offs we do on pre-1960 homes.
- Ice dam blowouts at eaves and valleys. Greensburg’s elevation forces more freeze-thaw cycling than Pittsburgh sees, and without proper ice-and-water shield extending six feet from the eave, meltwater backs up under shingles and pours into wall cavities. We see this every late winter on homes where out-of-town crews skimped on underlayment.
- Subsidence-related ridge sag masked by new roofing. Westmoreland County’s coal mining legacy means some Greensburg roof planes have developed a subtle bow or sag over decades. Lay new shingles over that without identifying the cause, and you’ll have wavy courses, premature granule loss, and a problem that cost far more to fix later. We measure and document ridge line straightness before we commit to any replacement scope.
- Original Pennsylvania slate patched with incompatible materials. Some 1930s bungalows and early colonials still carry partial slate roofs. Homeowners patch with asphalt, caulk, or metal - materials that expand and contract at different rates, accelerating the deterioration of surrounding slate. We assess whether selective slate repair is viable or whether full replacement with a modern system makes more sense.
Pricing for Roof Replacement & Installation in Greensburg, PA
| Service | Typical Range in Greensburg | What Drives Cost |
|---|---|---|
| Asphalt shingle replacement (1,800-2,400 sq ft) | $8,500-$15,000 | Deck condition, pitch, dormers/valleys |
| Asphalt shingle replacement (2,400-3,500 sq ft) | $12,000-$18,000 | Complexity, accessibility, tear-off layers |
| Standing seam metal roofing | $14,000-$28,000 | Gauge, seam type, panel length, underlayment |
| Full deck replacement (per sq ft) | $3.50-$6.00 | Skip sheathing removal, rafter repair needs |
| Ice & water shield upgrade (if missing) | $800-$1,800 | Roof perimeter linear feet, valley count |
These are Greensburg-specific ranges based on local material costs, Westmoreland County permit fees, and the deck conditions we typically encounter in this market. A 1920s Academy Hill colonial with original skip sheathing and two layers of asphalt to remove sits at the higher end. A 1990s ranch with solid OSB and a single layer falls toward the lower. We don’t guess over the phone - we inspect, photograph, and deliver a written estimate with one number on it. The number on the estimate is the number on the invoice.

FAQs - Roof Replacement & Installation in Greensburg
Greensburg’s elevation in the Laurel Highlands foothills - roughly 1,000-1,100 feet versus Pittsburgh’s 700-800 feet - means freeze-thaw cycles are substantially more frequent, accelerating the deterioration of any compromised decking. Combined with the widespread presence of original skip sheathing under old asphalt overlays, hidden deck rot is far more common here. A roof that might survive an overlay in Pittsburgh often needs full tear-off and re-decking in Greensburg to last. Call (844) 563-1816 and we’ll show you exactly what your deck looks like.
Generally, no - not on Greensburg’s older housing stock. The weight of metal over existing shingles plus the unknown condition of skip sheathing beneath creates too much risk. We pull to the deck, inspect, and build from a clean substrate. Metal roofing’s real advantage in Greensburg is snow shedding and ice dam resistance, but only when installed properly with correct underlayment and ventilation. Call for an assessment of your specific roof structure.
Stop and get a professional inspection before any new roofing goes on. That bow may indicate historic subsidence from Westmoreland County’s deep coal mining legacy - a structural issue that new shingles will only hide and worsen. We measure ridge straightness with a string line during every pre-replacement inspection. If we find sag, we’ll recommend a structural engineer and coordinate with them before we proceed. Covering it over is not an option we offer.
Six feet from the eave minimum, full valley runs, and around every penetration - that’s our standard on every Greensburg job, not an upgrade. The freeze-thaw intensity at this elevation, combined with orographic snowfall off Chestnut Ridge, makes anything less a gamble we won’t take. We’ve seen too many February ice dam blowouts on homes where two feet of shield was treated as sufficient. Call (844) 563-1816 for a free estimate - we’ll specify exactly what your roof needs.
Selective repair is sometimes possible if the substrate is sound, matching slate is available, and the damage is limited to a few courses. More often, we find the original skip sheathing has deteriorated, flashings have been patched with incompatible materials, and the cost of proper slate restoration exceeds that of a full replacement with a modern system designed for Greensburg’s climate. We document what you have, explain both paths, and let you decide. Call (844) 563-1816 for an honest assessment.
In the Academy Hill neighborhood, we replaced a 1920s brick colonial’s original Pennsylvania slate with GAF Timberline shingles. The skip sheathing had rotted under a flawed asphalt overlay - our crew pulled the deck, installed full OSB with Grace Ice & Water Shield at the eaves, and avoided the bow from minor subsidence. The homeowners now have a 50-year system that handles the Laurel Highlands’ snow loads. That’s the work we stand behind.
