Fast, Reliable Roof Replacement & Installation Across Crafton
A full roof replacement on a typical Crafton home runs $8,500-$18,000 depending on size, pitch, and whether original board sheathing needs upgrading. Most replacements in the borough take 2-4 days once materials arrive, and our Roof Replacement & Installation team keeps GAF, CertainTeed, and Atlas shingles stocked regionally for faster turnaround. If you’re seeing water stains on your ceiling after a freeze-thaw cycle, or if your slate or asphalt roof is past twenty-five years, call (844) 563-1816. A live person answers, day or night, and we’ll get a uniformed technician out to your Crafton home for a photo-documented inspection.
We’ve worked the steep streets of Crafton since 1984 - from the Victorian foursquares along Bradford Avenue to the Craftsman bungalows tucked above Idlewood. This borough’s hillsides demand a different kind of roofer than the flat creek-bottom towns nearby. We bring extension staging, roof jacks, and crews trained for slate repair and steep-slope safety, because a contractor who treats your Crafton roof like a suburban ranch in Ohio is going to have a bad day, and so will you.

We know Crafton’s specific challenges: the channeled northwest winds that strip granules from south-facing slopes, the freeze-thaw flashing failures at pre-war chimneys, the moss colonization on north planes that shortens shingle life compared to sunnier markets. This isn’t textbook knowledge. It’s forty-two years of reading the actual roofs above Chartiers Creek.
Our Roof Replacement & Installation Services in Crafton
Full Roof Replacement
Most Crafton homes built between 1895 and 1940 are now on their second or third roof, and many are due. A full replacement strips the existing system to the deck, addresses any rotted board sheathing, and installs a complete new system with proper underlayment, ice-and-water shield at valleys and eaves, and ventilation balanced to Pittsburgh’s humid summers and freeze-thaw winters. On Crafton’s steeper streets, where the grade drops sharply away from the curb, the rear slope of a home is often a full story taller than the front-facing slope. This catches flat-lot contractors off guard and demands specialized extension staging or roof jacks - equipment we carry standard. On a 1920s Craftsman bungalow on Idlewood Avenue, we removed a failing original slate roof and installed GAF Timberline HDZ shingles. The rear slope required roof jacks and extension staging due to the grade dropping sharply away from the curb, adding critical setup time that we planned for, not around.

Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most Crafton homeowners replacing legacy slate or worn early-generation asphalt. We install GAF, CertainTeed, Owens Corning, and Atlas systems with proper nail patterns and synthetic underlayment. Here’s the local consideration: Crafton’s original board sheathing, common in pre-1940 construction, lacks the nail-holding capacity of modern plywood. Without addressing this during installation, channeled northwest winds off the Ohio valley can lift shingles that would hold fine on a newer deck. We inspect every deck and recommend upgrades where needed. A typical asphalt re-roof on a 1,200-1,800 square foot Crafton home runs $8,500-$14,000.

Slate Repair and Replacement
Many Crafton homes still carry original or first-generation slate, especially the Victorian foursquares near the borough center. Slate can last a century, but the fasteners, flashing, and underlayment beneath it do not. We repair slate where feasible - matching Pennsylvania black or Vermont unfading green - and advise honestly when patching is throwing good money after bad. Full slate replacement on a typical Crafton home runs $18,000-$35,000, but preserves architectural integrity that asphalt cannot replicate. If you’re in a designated historic area or simply love the look, we’ll walk you through the real costs and timeline.

New Construction Roofing
For additions and new builds in Crafton’s remaining infill lots, we design roof systems that respect the borough’s streetcar-era scale and complex rooflines. New construction allows modern sheathing, proper ventilation, and ice-and-water shield from day one - advantages no retrofit can fully match. We coordinate with your builder on staging in tight hillside lots where driveway access is limited and material delivery requires planning.

Common Roof Replacement & Installation Problems We See in Crafton Homes
- Freeze-thaw flashing failures: Pittsburgh’s frequent oscillations around 32°F each winter drive ice dam formation that lifts flashing at chimney and dormer junctions. On Crafton’s pre-war homes, original lead flashing has often crystallized and cracked, creating attic leaks that appear as mysterious ceiling stains after every January thaw.
- Board sheathing blow-off: Original board sheathing - not plywood - lacks nail-holding capacity. Under channeled northwest winds off the Ohio valley, shingles fastened to aging boards can release in sections that would hold firm on modern decking. We see this most on south- and west-facing slopes where wind exposure is highest.
- Complex valley rot: Crafton’s multi-plane rooflines, with dormers and intersecting slopes on narrow hillside lots, create valleys that collect debris and trap moisture. Without proper valley lining and regular clearing, accelerated rot develops at the sheathing level, often hidden until replacement exposes it.
- Moss and algae shortening shingle life: Annual cloud cover in this part of Pennsylvania fosters persistent moss colonization on north-facing roof planes. Moss holds moisture against shingle surfaces and wicks water under laps, shortening effective lifespan by several years compared to sunnier, drier markets.
Pricing for Roof Replacement & Installation in Crafton, PA
Roofing costs in Crafton run higher than flat-lot suburbs because of steep-slope access, complex rooflines, and the frequent need to address original board sheathing. Here’s what we see in the local market:
| Service | Typical Range in Crafton |
|---|---|
| Asphalt shingle replacement, 1,200-1,800 sq ft | $8,500-$14,000 |

| Steep-slope staging surcharge (rear slope >1 story differential) | $800-$2,000 |
Factors that move you within these ranges: roof pitch and accessibility, number of penetrations (chimneys, dormers, vents), sheathing condition, and whether we’re matching existing slate or switching to asphalt. We provide no-hassle upfront pricing: the number on the estimate is the number on the invoice. No surprises. Call (844) 563-1816 for a free, no-pressure inspection and exact quote.

FAQs - Roof Replacement & Installation in Crafton
Ice damming is worse on older Crafton homes because pre-1940 construction typically lacks adequate attic insulation and ventilation, and original lead flashing at chimneys and dormers has often cracked from age and crystallization. When Pittsburgh’s frequent freeze-thaw cycles hit, melted snow runs down the roof, refreezes at the cold eave, and backs up under lifted flashing into the attic. We address this with proper ice-and-water shield, ventilation corrections, and flashing replacement during re-roofing. Call (844) 563-1816 for an inspection - estimates are free.
Yes, most Crafton homes originally roofed in slate can accept asphalt shingles, but the roof deck must be evaluated first. Original board sheathing often needs upgrading to modern plywood or OSB for proper nail holding, and the added weight difference (slate is heavier) is not a structural concern - asphalt is lighter. The choice is aesthetic and financial: asphalt runs $8,500-$14,000 where matching slate might cost $18,000-$35,000. We will not pressure you either direction. Call (844) 563-1816 and we’ll show you both options on your actual roof.
On Crafton’s steep hillside streets, the rear slope is often literally a full story taller than the front because the lot grade drops sharply away from the curb toward the rear property line. This is normal for the borough’s topography, but it surprises contractors accustomed to flat-lot work. The added height requires extension staging, roof jacks, and longer material hoists, which adds setup time and cost. We plan for this on every Crafton estimate. If a contractor didn’t mention it, ask why. Call (844) 563-1816 for an inspection that accounts for your actual site conditions.
Not always, but we inspect it thoroughly. Original board sheathing in Crafton’s 1895-1940 homes is typically 1×6 or 1×8 planks with gaps that expand and contract. If boards are sound and gaps are manageable, we can install a layer of OSB or plywood over them for a solid fastening surface. If boards are rotted, cracked, or insufficiently thick for modern fastening patterns, replacement is necessary to prevent blow-off under northwest winds. This typically adds $1,500-$4,000. We’ll show you photos of your actual deck and explain what we found. Call (844) 563-1816 for a free inspection.
Moss shortens slate roof lifespan by holding moisture against the stone and wicking water into laps and fasteners, accelerating freeze-thaw damage and metal corrosion. On Crafton’s north-facing slopes, where annual cloud cover keeps surfaces damp, moss colonization is particularly aggressive. Slate itself is durable, but the nails and underlayment beneath it are not. Regular gentle cleaning and proper ventilation help, but if moss has been established for years, we often find hidden fastener corrosion during inspection. We can assess the real condition beneath the surface. Call (844) 563-1816 for a photo-documented evaluation.
