Fast, Reliable Roof Replacement & Installation Across Jeannette
Most full roof replacements in Jeannette run $12,500-$28,000 depending on whether your home needs new plywood decking, which the majority of pre-1930 houses here do. We’re typically on-site in Jeannette within 24-48 hours of your call, and most replacements are completed in two to three days once materials arrive. Call (844) 563-1816 - a live person answers, even at midnight after a wind storm takes shingles off your Clay Avenue cottage.
We’ve been climbing roofs in Westmoreland County since 1984. Jeannette’s not just another pin on our map. It’s a city we know block by block: the steep-pitched worker cottages along Division Street, the late-Victorian frames on Clay Avenue, the narrow eave overhangs that channel water straight to the foundation when gutters fail. Our crews have replaced roofs within sight of the old Jeannette Glass plant site, and we’ve learned what holds up in these foothills and what doesn’t. When you hire Ridgeline Roofing Co., you’re getting a contractor who understands that Jeannette’s housing stock isn’t generic - and neither is the work it demands.
Why Ridgeline Roofing Co. Is Jeannette’s Preferred Roof Replacement & Installation Company
Forty-two years in business means we’ve seen every roofing fad come and go. Storm-chasers roll through Westmoreland County after every hail event, knock doors with out-of-state plates, and vanish before the caulk dries. We’re the opposite. Ridgeline Roofing Co. was founded in 1984, trains local apprentices into journeymen, and plans to be answering phones in Jeannette long after those trucks have moved to the next county.
Our reputation here is built on one thing: we come back if something’s not right. The 90-Day Done Right Promise is a written workmanship guarantee with no paperwork to file, no arguments, no runaround. If it’s not right, we make it right. Period. That matters on a 1920s frame home where the chimney flashing is original and the skip sheathing hasn’t been exposed since the Hoover administration.
Every call rings through to a live person, 24 hours a day, seven days a week. Not a voicemail tree. Not a “we’ll call you back between 9 and 5.” When ice dams back up into your shed dormer at 2 a.m. in February, someone who can dispatch a crew answers the phone. Our technicians are background-checked, uniformed, and photo-document every inspection from your actual roof - not the driveway with a scary speech about “what could happen.”
We don’t bait-and-switch on pricing. The number on your estimate is the number on your invoice. For Jeannette homeowners who’ve lived in their houses twenty, thirty, forty years and intend to stay, that’s the square deal you’re looking for.
Our Roof Replacement & Installation Services in Jeannette
Full Roof Replacement
This is what we do most in Jeannette, and it’s rarely straightforward. On a late-Victorian cottage on Clay Avenue, we lifted the third course of failing three-tab shingles to find original skip sheathing with 3-inch gaps. We installed GAF Timberline HDZ over full 7/16-inch OSB decking, matching the steep 10/12 pitch that the glassworkers’ homes were built with, and sealed the step flashing at the brick chimney - a common Jeannette failure point. Full replacement on these homes runs $14,000-$28,000 because the re-decking is essentially mandatory. Compare that to a 1970s ranch in Murrysville where you might nail straight to existing plywood, and you’ll understand why Jeannette pricing has its own logic.
New Construction Roofing
New builds in Jeannette are less common than heritage renovations, but when we’re called to additions or rebuilds after fire or collapse, we spec for the local climate. That means full ice and water shield at valleys and eaves, proper ventilation to combat the freeze-thaw cycling that hits harder at Jeannette’s 1,000-foot elevation than down in Pittsburgh, and materials rated for the snow loads these foothills receive. We coordinate directly with your builder and pull permits through Westmoreland County - no shortcuts, no “we’ll handle it later.”
Asphalt Shingle Installation
Asphalt shingles are what most Jeannette homeowners choose for their replacement, and we install them properly for this market. The south-facing slopes on your pre-1930 home take a beating from UV and temperature swings that crack granules and split shingles before their time. We spec GAF and CertainTeed architectural lines with enhanced sealant strips and full synthetic underlayment, not the bargain three-tabs that some crews slap on to win the low bid. A typical asphalt re-roof on a Jeannette worker cottage with re-decking runs $12,500-$19,500.
Metal Roofing
For homeowners who intend to stay forever - and many Jeannette residents do - metal is worth the premium. Standing-seam aluminum or steel sheds snow faster than asphalt, eliminates ice dam formation on those troublesome low-slope porch roofs, and carries 40-50 year warranties that outlive most mortgages. We install Atlas and Tamko metal systems, properly flashed at chimneys and dormers, with hidden fasteners that won’t back out in Jeannette’s thermal expansion cycles. Expect $22,000-$38,000 for a full metal replacement with re-decking on a typical two-story cottage.

Trusted Brands We Service in Jeannette
We’re authorized installers for seven manufacturer lines - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we don’t substitute materials without your written approval. For Jeannette’s market, we stock GAF Timberline HDZ and Atlas StormMaster Slate in our regional warehouse, which means faster turnaround on standard colors instead of waiting three weeks for a special order. We match the product to the house: GAF’s heavier architectural shingles for steep pitches that shed snow loads, Atlas’s impact-resistant lines if your home sits exposed to the foothill winds that rake Route 30. Every installation carries the manufacturer’s full warranty plus our own 90-Day Done Right Promise on workmanship.
Common Roof Replacement & Installation Problems We See in Jeannette Homes
- Cracking and granule loss on south-facing slopes. Jeannette’s elevation and exposed position in the Westmoreland County foothills mean more freeze-thaw cycles than Pittsburgh sees. Asphalt shingles on south-facing pitches cycle through expansion and contraction daily from late November through March, accelerating granular erosion and surface cracking that would take years longer in milder microclimates.
- Ice dam water intrusion at low-slope shed dormers and porch roofs. The pre-1930 worker cottages on Division Street and surrounding blocks were built with minimal insulation and ventilation by modern standards. Heat loss melts snow from below; water runs to the cold eave and refreezes. The resulting dam backs up under shingles and into wall cavities. We’ve replaced rotted rafter tails on dozens of these dormers.
- Step flashing failure at brick chimney stacks. Century-old mortar in Jeannette’s chimney construction deteriorates faster than the brick itself, creating gaps where step flashing should seal tight. Combine that with thermal movement in the foothill freeze-thaw cycle, and you get the chronic leaks we see around chimneys on Clay Avenue and throughout the 15644 zip code.
- Structural rot in skip sheathing and rafter ends. Original 1×4 skip sheathing with 2-3 inch gaps was never designed to shed water - it was sized for slate that overlapped like fish scales. When later homeowners or cut-rate roofers laid asphalt directly over that gap-toothed substrate, wind-driven rain and slow leaks rotted the sheathing and often the rafter tails beneath. By the time we lift the old roof, we’re looking at structural repair, not just surface replacement.
Pricing for Roof Replacement & Installation in Jeannette, PA
Here’s what we’ve actually charged on recent Jeannette jobs, with the understanding that every roof tells its own story once we peel back the layers:
| Service | Typical Range in Jeannette |
|---|---|
| Asphalt shingle replacement (with re-decking) | $12,500 - $19,500 |
| Asphalt shingle replacement (no re-decking needed) | $9,500 - $14,000 |
| Metal roof replacement (with re-decking) | $22,000 - $38,000 |
| Full plywood re-decking (materials + labor) | $3,500 - $7,500 |
| Chimney step flashing rebuild | $1,200 - $2,800 |
| Ice and water shield upgrade (full roof) | $1,800 - $3,200 |
The re-decking cost is the Jeannette variable. On homes built after 1950 with solid plywood or plank decking, you won’t face it. On the glass-industry cottages and Victorians that define this city’s housing stock, it’s nearly unavoidable - and any estimate that doesn’t account for it is either uninformed or dishonest. We price it upfront so you’re not staring at a change order mid-job.
We offer free written estimates, a free second opinion on any written estimate you’ve already received, and a permanent 5% senior and veteran discount. Call (844) 563-1816 to schedule - we’ll photograph what we find and walk you through it before you commit to anything.

FAQs - Roof Replacement & Installation in Jeannette
Because the original glass-industry worker housing was built with 1×4 skip sheathing spaced 2-3 inches apart, sized for Pennsylvania slate that overlapped to shed water. Modern asphalt shingles and underlayment require a solid substrate to meet manufacturer warranty and code requirements. When our Roof Replacement & Installation crew lifts the old roof on a pre-1930 Jeannette home, we find that gap-toothed sheathing almost every time. Full plywood or OSB decking is not optional - it’s the foundation everything else builds on. Call (844) 563-1816 for a free inspection and we’ll show you exactly what your roof is sitting on.
Sometimes, but the economics rarely work in Jeannette’s favor. Pennsylvania slate has a 75-100 year lifespan, and most of Jeannette’s original roofs have exceeded that. Matching salvaged slate is expensive and labor-intensive, and the underlying fasteners and flashings are usually corroded. We’ve done selective slate repairs on heritage homes where the owner insisted, but a full replacement with modern materials typically costs less than half of a proper slate restoration. If your slate is sound and the flashing is the only problem, we’ll tell you. If it’s failing across the field, we’ll show you why replacement makes more sense. Estimates are free - call (844) 563-1816.
Jeannette sits at roughly 1,000 feet in the Westmoreland County foothills, which means more snow accumulation and more freeze-thaw cycles than Pittsburgh at lower elevation. Asphalt shingles expand in afternoon sun and contract overnight through late winter, accelerating thermal fatigue. Granule loss, surface cracking, and sealant strip failure all happen faster here than in milder microclimates. We spec shingles with enhanced adhesive bands and install full synthetic underlayment as a secondary water barrier - not because it’s required by code, but because we’ve seen what Jeannette winters do to roofs cut to the minimum. For a brand recommendation specific to your home, call (844) 563-1816.
We most often install GAF Timberline HDZ on Jeannette’s steep-pitched worker cottages and Victorians. The LayerLock technology and StrikeZone nailing area handle the 10/12 and 12/12 pitches common in the 15644 zip code, and the Dura Grip adhesive resists wind uplift on exposed foothill sites. For homes with more complex dormer and chimney penetrations, CertainTeed Landmark PRO’s dual-layer construction gives extra protection at the valleys and step flashings where we see the most leaks. Both carry 50-year limited warranties when installed by an authorized contractor like Ridgeline. We’ll walk you through the choice on your free estimate - call (844) 563-1816.
Not the entire roof, but more than code minimum. We install full ice and water shield at all eaves (extending 24 inches past the interior wall line), in valleys, around chimneys, and at all penetrations - standard practice for our Jeannette jobs. On low-slope porch roofs and shed dormers, where ice damming is chronic on pre-1930 homes, we often recommend full coverage as an upgrade. It’s an added cost, but we’ve torn out too many rotted rafter tails to treat it as optional in those applications. We’ll photograph your specific conditions and give you an honest recommendation. Call (844) 563-1816 for a free inspection.
