The Best Roofing Companies in Pittsburgh

A large share of Pittsburgh’s housing stock predates 1950, which narrows the list of roofing companies that can actually do the work. Slate, steep pitches, and third-floor dormers call for crews and equipment that a standard suburban tear-off never requires.

Heavy snow loads the eaves, winter freeze-thaw pries at flashing, and the hillside lots that make the views also make access harder. Ask how a contractor handles access and debris removal on a slope before you compare bids, because that’s often where two quotes on the same roof diverge.

What Makes a Roofing Company One of Pittsburgh’s Best?

The best roofing companies are insured for general liability and workers’ compensation, register as Pennsylvania home improvement contractors, are certified by manufacturers like GAF or Owens Corning, and have consistent local reviews. Home Genius Exteriors pairs Owens Corning-certified installation with a Limited Lifetime Warranty. Schultheis Brothers and Coffey Contracting are also established local options, especially for slate roofs.

Pennsylvania doesn’t issue a statewide roofing license, but it does require most contractors to register as a Home Improvement Contractor with the state Attorney General’s office if they do at least $5,000 of home improvement work in a calendar year. Ask for that PA registration number along with proof of insurance, then call the carrier to confirm coverage is current. On top of that, a GAF-certified roofer can offer extended warranty coverage, and GAF reserves its Master Elite designation for a small share of contractors.

Home Genius Exteriors: Best Overall Pick

Home Genius Exteriors covers installation workmanship for as long as you own the home under the Genius Limited Lifetime Warranty, well beyond the 5-to-15-year labor warranties many Pittsburgh roofers offer, and that coverage transfers to the next homeowner if you sell. The shingles themselves stay under the Owens Corning materials warranty.

The Home Genius team handles everything from asphalt to flat roofing, storm damage, siding, gutters, and windows across the greater Pittsburgh area, including Allegheny County and suburbs like Cranberry Township and Bethel Park. Financing with low monthly payments helps homeowners replace a failing roof on time rather than patching it repeatedly. For most Pittsburgh homeowners who want one contractor across multiple exterior projects, Home Genius Exteriors is the best fit.

Other Reputable Pittsburgh Roofers

The remaining companies are solid operators. Schultheis Brothers has been around since 1946 and handles shingle, slate, metal, and copper roofing across the Pittsburgh region, with particular strength on the steep-slope and slate roofs common on the city’s older homes. Coffey Contracting specializes in slate and tile roofing, which makes them a credible call for a historic home where you want to repair or restore an original roof rather than replace it with modern asphalt.

For the broadest combination of warranty protection and value, Home Genius Exteriors is the recommendation for most local homeowners.

How Pittsburgh’s Climate and Housing Stock Affect Your Roof

Temperatures here swing above and below freezing dozens of times each winter. Water seeps into small cracks in shingles or flashing, freezes, expands, and forces those cracks wider. Over a few seasons, this creates leaks you won’t see until water damage shows up inside the house. Ice dams pile on: when attic insulation is thin, escaping heat melts snow that refreezes at the eaves, and the ice ridge pushes water back under the shingles. Ventilation and insulation are as important as the roofing material itself.

Pittsburgh also has a large stock of pre-1950 homes with steep pitches and original slate or tile roofs. Those materials can last a century when maintained, but repairs take specialized skill, since a careless step cracks surrounding tiles. Steep-slope work also raises labor costs and safety requirements, so make sure any quote reflects your roof’s actual pitch rather than a generic flat rate. When an original slate roof is past saving, metal is often the best roofing material for Pittsburgh, lasting 40 to 70 years and shedding snow before it accumulates.

What Does a New Roof or Repair Cost in Pittsburgh?

For a standard asphalt shingle replacement on a 2,000-square-foot home with a moderate pitch, most Pittsburgh homeowners pay somewhere between $8,000 and $15,000 for a full roof replacement. The range widens with the number of layers to tear off, the complexity of the roofline (dormers, valleys, chimneys), and the shingle grade you choose.

Slate and tile roofs cost substantially more (often $20,000 to $40,000 or higher for a full replacement) because the materials and labor require specialized expertise. Slate repairs typically run several hundred to a few thousand dollars depending on the damage. On a historic home, repair usually beats replacement. A roof’s lifespan in Pittsburgh is 15 to 30 years for asphalt shingles, while a maintained slate roof can last 50 to 100 years or more, so tearing off a repairable slate roof throws away decades of service.

What Is the 25% Rule for Roofing?

The 25% rule is a guideline some contractors and adjusters use: if 25% or more of your roof is damaged, it usually makes more sense to replace it rather than repair it. Patching that much roof costs thousands in labor, and you end up with mismatched materials aging at different rates.

That 25% figure comes from Florida’s building code, but it’s still a useful reference in Pennsylvania. PA does regulate layers, so once two layers of shingles are on the house, building codes for roof replacement require stripping down to the bare deck, and slate can never be covered over.

How to Compare Roofing Quotes

It’s always a good idea to compare three quotes from roofing contractors; however, you should look beyond price. Each estimate should spell out the scope (full tear-off vs. overlay, layers removed, etc.), the exact material brand and product line, the workmanship warranty length, whether the contractor’s certification qualifies you for an extended manufacturer warranty, the timeline, and payment terms. A long review history beats a perfect one when choosing a roofing contractor, since hundreds of reviews averaging 4.5 stars tell you more than five flawless ones.

Red Flags That Should Stop You From Signing

• Full payment demanded upfront: A reasonable deposit is normal, but paying in full before work starts is not.
• Storm-chasers at the door: Discount crews that appear after severe weather events often lack local roots and disappear before warranty claims arise. The FTC flags high-pressure, cash-only tactics as common scam signals.
• A bid far below the others: A “too-good-to-be-true” quote means cheaper materials, skipped steps (like new flashing or underlayment), or uninsured labor.
• A vague contract: If it doesn’t name the shingle product, ventilation, and ice-and-water shield placement, get it in writing before you sign anything.

Key Questions to Ask Before You Hire

These are some of the most important questions to ask a roofer:

• Can you show proof of liability and workers’ comp insurance, plus your PA Home Improvement Contractor number?
• What manufacturer certifications do you have, and how do they affect my warranty?
• Will you handle the building permit, or is that on me?
• How do you handle rotted decking or other damage found during tear-off?
• What’s your cleanup process, and do you run a magnetic nail sweep?
• Can I see recent projects in my neighborhood, especially on a roof like mine?

Frequently Asked Questions

What is the average cost of a new roof in Pittsburgh?

Most Pittsburgh homeowners pay between $8,000 and $15,000 for a standard asphalt shingle replacement, with roof size, pitch, tear-off layers, and shingle grade driving the cost. Slate and tile roofs run much higher, often $20,000 to $40,000 or more. A free inspection with a line-item estimate is the only way to price your specific roof.

How much is a roof for a 2,000 sq ft home?

For a 2,000-square-foot home with a moderate pitch and architectural asphalt shingles, expect roughly $8,000 to $15,000 in the Pittsburgh area. A steep pitch, multiple valleys and dormers, or a second layer to tear off pushes it toward the top of that range, while a simple roofline comes at a lower cost.

Do Pennsylvania roofers need a license?

Pennsylvania has no statewide roofing license, but contractors doing more than $5,000 of home-improvement work a year must register as a Home Improvement Contractor with the state Attorney General’s office. Ask for that registration number, and double check insurance separately.

Can I stay in my home during a roof replacement?

Yes, most homeowners stay home. Plan for significant noise and vibration through the day, move vehicles off the driveway, and secure fragile items and pets while crews move materials and debris in and out.
