Best Roofing Companies in Pennsylvania 2026
Best Roofing Companies in Pennsylvania 2026
Pennsylvania’s climate — heavy snow, ice dams, nor’easters, and summer thunderstorms — demands roofing contractors who know how to build for four-season punishment. The state also has one of the highest concentrations of historic homes in the country, many with original slate roofs that require specialized restoration skills. The companies ranked below cover both modern installations and historic preservation, with proven track records across the state.
A typical roof replacement in Pennsylvania costs $8,000 to $14,000 for asphalt shingles and $14,000 to $24,000 for metal. Slate work ranges from $25,000 to $45,000 for a full replacement. The right contractor makes the difference between a roof that lasts 25 years and one that fails in 10. Here are the top roofing companies serving Pennsylvania homeowners in 2026.
1. Keystone Roofing Solutions
Headquarters: Allentown, PA
Service Area: Lehigh Valley, Berks County, Bucks County, Montgomery County
Specialties: Slate restoration, asphalt, metal roofing
Years in Business: 28
Certifications: GAF Master Elite, CertainTeed SELECT ShingleMaster
Average Project Cost: $9,500 – $35,000
Keystone Roofing Solutions is one of the few Lehigh Valley contractors with a dedicated slate restoration division. Their slate crew includes two craftsmen who trained under retired quarry workers from the Bangor slate region — a lineage of knowledge that’s difficult to find. The company handles everything from standard asphalt tear-and-replace jobs to full slate roof restorations on 150-year-old homes in Bethlehem’s historic district. Their GAF Master Elite certification means they can offer 50-year system warranties on asphalt installations, and their slate work carries a 25-year craftsmanship warranty. Customers consistently praise their communication and cleanup — two areas where many roofing companies fall short.
2. Steel City Roofing & Exteriors
Headquarters: Pittsburgh, PA
Service Area: Allegheny, Westmoreland, Butler, Washington, Beaver counties
Specialties: Steep-slope roofing, metal, storm damage repair
Years in Business: 22
Certifications: Owens Corning Platinum Preferred, HAAG Certified Inspector
Average Project Cost: $8,500 – $18,000
Steel City Roofing has built its reputation on Pittsburgh’s toughest roof jobs — the steep hillside homes in neighborhoods like Mount Washington, Polish Hill, and Troy Hill where standard crews won’t work. Their HAAG storm damage certification means they can provide insurance-grade damage assessments, which speeds up the claims process for homeowners dealing with hail or wind damage. The company also specializes in standing seam metal installations on both residential and light commercial buildings. Their crews are experienced with the access challenges common in Pittsburgh’s dense, hilly neighborhoods — narrow streets, limited staging areas, and properties you can only reach by foot.
3. Heritage Slate Works
Headquarters: Doylestown, PA
Service Area: Bucks County, Montgomery County, Philadelphia, Chester County
Specialties: Slate roof restoration, copper work, historic preservation
Years in Business: 35
Certifications: National Slate Association member, PA Historic Preservation approved
Average Project Cost: $15,000 – $55,000
Heritage Slate Works is a true specialty contractor — they do slate and copper, and they do it at a level that few companies in the mid-Atlantic can match. Founded by a third-generation slater, the company works almost exclusively on historic and high-end residential properties. Their clients include homeowners in Philadelphia’s Society Hill and Chestnut Hill, historic estates in Bucks County, and institutional buildings throughout southeastern Pennsylvania. Heritage Slate carries an inventory of salvaged Pennsylvania slate for patch repairs, so replacements match the original roof rather than standing out as obvious patches. Their pricing reflects the specialty — this is not the company for a budget shingle job — but for anyone with a slate roof worth preserving, they’re the top choice in the region.
4. Commonwealth Roofing Group
Headquarters: Harrisburg, PA
Service Area: Dauphin, Cumberland, York, Lancaster, Lebanon counties
Specialties: Asphalt shingles, metal roofing, flat commercial roofs
Years in Business: 18
Certifications: GAF Master Elite, NRCA member
Average Project Cost: $8,000 – $16,000
Commonwealth Roofing covers central Pennsylvania’s residential and commercial market with a team of 35+ full-time installers. They’re the largest roofing contractor in the Harrisburg metro and handle volume efficiently — their scheduling system typically gets projects started within 2 to 3 weeks of signing, compared to the 4 to 8 week wait common with smaller companies during peak season. The company offers both asphalt and metal options and has seen its metal roofing business grow significantly in the last five years as rural homeowners in Lancaster and York counties move away from asphalt for long-term value. Their pricing is competitive for the region, and they offer 12-month same-as-cash financing through a lending partner.
5. Alpine Roofing & Snow Guard Systems
Headquarters: Scranton, PA
Service Area: Lackawanna, Luzerne, Monroe, Pike, Wayne counties
Specialties: Snow load engineering, ice dam prevention, metal roofing
Years in Business: 24
Certifications: CertainTeed SELECT, Snow Guard Manufacturers Association member
Average Project Cost: $9,000 – $20,000
Alpine Roofing operates in Pennsylvania’s heaviest snow zone — the Poconos and northeastern mountains where annual snowfall regularly exceeds 50 inches. Their expertise in snow load engineering and ice dam prevention sets them apart from general roofers. Every installation includes proper ice and water shield membrane, adequate ventilation assessment, and snow guard systems on metal roofs to prevent dangerous snow slides. Alpine’s crews install year-round, including cold-weather asphalt installation using hand-sealing techniques required when temperatures drop below 40 degrees. Their metal roofing installations are specifically designed for snow country — standing seam profiles with engineered snow retention that comply with local building codes for high-snow-load areas.
6. Liberty Bell Roofing
Headquarters: King of Prussia, PA
Service Area: Philadelphia, Montgomery, Delaware, Chester counties
Specialties: Suburban residential, insurance claims, full exterior
Years in Business: 15
Certifications: Owens Corning Platinum Preferred, BBB A+ rated
Average Project Cost: $10,000 – $16,000
Liberty Bell Roofing serves the Philadelphia suburbs with a focus on quality residential work in the $10,000 to $16,000 range — the sweet spot for typical colonial and split-level homes in Montgomery and Delaware counties. Their insurance claim department is a standout feature. After storm events, their HAAG-certified estimators provide documentation that matches insurance adjuster formats, reducing the back-and-forth that delays claim payouts. The company also handles siding, gutters, and window installation, making them a one-stop option for homeowners doing full exterior renovations. Online reviews consistently mention their project managers’ communication — you get daily updates with photos during the installation.
7. Three Rivers Metal Roofing
Headquarters: Greensburg, PA
Service Area: Westmoreland, Allegheny, Fayette, Somerset, Indiana counties
Specialties: Standing seam metal, agricultural metal, residential metal
Years in Business: 20
Certifications: Sheffield Metals certified installer, MCA member
Average Project Cost: $14,000 – $28,000
Three Rivers Metal Roofing is a dedicated metal roofing contractor — they don’t install asphalt shingles, and that singular focus shows in their work quality. They handle both residential standing seam installations and agricultural building roofing across western Pennsylvania. Their in-house roll-forming equipment means they fabricate panels on-site to the exact length needed, eliminating seams and reducing leak potential. For homeowners in western PA’s snow-heavy areas, Three Rivers’ metal roofs shed snow naturally and eliminate the ice dam problems that plague asphalt shingle roofs. Their pricing is at the upper end for the region, but the product comes with a 40-year paint warranty and a lifetime structural warranty.
8. Pinnacle Roofing Contractors
Headquarters: Reading, PA
Service Area: Berks, Schuylkill, Lebanon, northern Chester counties
Specialties: Asphalt shingles, flat roofs, commercial roofing
Years in Business: 12
Certifications: GAF Certified, OSHA safety certified
Average Project Cost: $7,500 – $13,000
Pinnacle Roofing is a mid-market contractor that delivers solid residential work at competitive prices. Their Reading-area base gives them lower overhead than Philadelphia-area competitors, and those savings pass through to homeowners. Pinnacle handles both pitched and flat roofs — relevant in Reading and the surrounding boroughs where row homes with flat or low-slope roofs are common. Their flat roof expertise includes TPO, EPDM, and modified bitumen systems. The company’s simple quoting process — written estimates within 48 hours of inspection, no high-pressure sales tactics — has earned them strong word-of-mouth in the Berks County market. They offer 5-year workmanship warranties on all installations.

How to Vet a Roofing Contractor in Pennsylvania
Pennsylvania requires roofing contractors to register as Home Improvement Contractors (HIC) with the state Attorney General’s office. Beyond that minimum requirement, here’s what to check:
- HIC registration: Search the PA Attorney General’s HIC database. Any contractor who isn’t registered is operating illegally.
- Insurance certificates: Request current certificates of general liability ($1 million minimum) and workers’ compensation. Call the insurance company to verify — expired or fraudulent certificates are common among fly-by-night operators.
- Manufacturer certifications: GAF Master Elite, Owens Corning Platinum Preferred, and CertainTeed SELECT certifications require annual training, insurance verification, and minimum volume thresholds. These certifications also unlock extended warranty options.
- Written contract: PA law requires a written contract for home improvement projects. It must include the contractor’s HIC number, start and completion dates, total price, payment schedule, and a description of work and materials.
- References: Ask for 5 recent local references, not just 3. Call them and ask about communication, cleanup, and whether any warranty issues arose after completion.
Watch out for storm chasers — out-of-state crews that canvass neighborhoods after hail or wind events. They often quote low, use substandard materials, and leave the state before problems surface. If a crew knocks on your door unsolicited after a storm, get their HIC number and verify it before signing anything. Browse our home services directory for established Pennsylvania contractors. If you’re buying a home and the inspection flags roof issues, check first-time buyer programs that may include repair allowances, and use our mortgage calculator to see how a roof replacement affects your overall budget.
Pennsylvania Roofing Cost Factors
Several Pennsylvania-specific factors affect your roofing cost beyond the standard material and labor calculations:
- Ice and water shield: Required by code along eaves and valleys. Adds $500 to $1,500 to the project but prevents ice dam damage — the most common cause of winter roof leaks in PA.
- Snow load compliance: Northern tier counties require higher structural ratings. Your roofer should verify that the existing roof deck can handle the required snow load before installing new material.
- Historic district rules: Material restrictions in places like Bethlehem, Jim Thorpe, and parts of Philadelphia can limit your options to slate, copper, or approved synthetics — all more expensive than standard asphalt.
- Steep pitch premiums: Many Victorian-era PA homes have 8/12 or steeper roof pitches that require additional safety equipment and slower installation, adding 15% to 25% to labor costs.
- Disposal fees: PA landfill tipping fees for roofing waste average $45 to $65 per ton, varying by county.

Storm Damage Response: What to Do After a Storm
Pennsylvania sees hail, high winds, and nor’easters that damage roofs every year. If you suspect storm damage, follow this sequence:
- Document immediately. Take photos and video of visible damage from the ground — don’t climb on the roof. Photograph any debris, dislodged shingles on the ground, and water damage inside.
- File your insurance claim within 48 hours. Earlier is better. PA insurers have time limits on claim filing after storm events — check your policy for specific deadlines.
- Get a professional inspection. Have a HAAG-certified roofer inspect the roof and provide a detailed damage report. This report becomes the basis for your insurance claim. Most reputable roofing companies offer free post-storm inspections.
- Don’t sign anything at the door. Storm chasers canvass neighborhoods after weather events, pressuring homeowners to sign contracts on the spot. Take time to verify the company’s HIC registration, insurance, and references before committing.
- Get your own estimate. Don’t rely solely on the insurance adjuster’s assessment. If the adjuster’s estimate is significantly lower than your contractor’s, you can request a re-inspection or file a supplement.
PA law prohibits contractors from paying or waiving your insurance deductible — if a roofer offers to cover your deductible, they’re breaking state law and probably cutting corners on the job to make up the cost.
Frequently Asked Questions
How long should a roof last in Pennsylvania?
Asphalt architectural shingles last 20 to 30 years in Pennsylvania’s climate — slightly less than the manufacturer’s rated lifespan due to freeze-thaw stress and ice exposure. Standing seam metal lasts 40 to 60 years. Natural slate, properly maintained, lasts 75 to 150 years. The roof’s actual lifespan depends on ventilation, underlayment quality, and whether ice and water shield was installed correctly. A well-ventilated attic extends shingle life by 5 to 10 years compared to a poorly ventilated one.
What time of year is cheapest for roofing in Pennsylvania?
Late fall (November) and early spring (March-April) are the cheapest periods. Contractors are less booked and may offer 5% to 10% discounts to keep crews working. Summer and early fall are peak season with highest prices and longest wait times. Winter installation is possible for metal roofing but not recommended for asphalt shingles below 40 degrees.
Should I repair or replace my slate roof?
If fewer than 20% of slates are damaged or missing and the underlying deck is sound, repair and maintenance is more cost-effective than replacement. Individual slate replacement costs $300 to $800 per repair visit. If more than 30% of slates are failing, the deck is deteriorating, or the flashing is beyond repair, a full replacement is warranted. A good slate roofer can assess the remaining lifespan — healthy Pennsylvania slate can last another 50+ years even on a 100-year-old roof.
Does a new roof increase home value in Pennsylvania?
A new asphalt shingle roof typically recovers 60% to 65% of its cost at resale in the Mid-Atlantic region. The actual return varies — a visibly failing roof on a $250,000 home might cost $10,000 to replace but add $15,000 to the sale price because it removes a major buyer objection and makes the home financeable for FHA/VA buyers. The indirect value of a new roof (faster sale, fewer concessions) often exceeds the direct cost recovery.
How do I file an insurance claim for roof damage in PA?
Document the damage with photos immediately after the event. Contact your insurance company to file a claim within 24 to 48 hours. Request a contractor inspection from a HAAG-certified roofer who can provide an estimate in the format insurance adjusters use. Attend the adjuster’s inspection and have your contractor present. PA law gives you the right to choose your own contractor — you don’t have to use the insurance company’s preferred vendor. If the adjuster’s estimate is significantly lower than your contractor’s, request a re-inspection with supplemental documentation. Review our guide to how much roofing costs in Pennsylvania.
