Roof Replacement Contractors in Pittsburgh, PA: What to Ask Before You Hire
Pittsburgh housing stock is old, steep and often slate or low-slope — sometimes all three on the same house. That makes the cheapest bid the riskiest one here, because a crew set up for suburban asphalt work will not detail a 12/12 slate valley or a rowhouse flat roof correctly.

What a roof replacement costs in Pittsburgh
A 20 to 25 square asphalt shingle tear-off and replacement runs $10,500 to $18,000 in 2026. Steep pitches, third-story access and multiple existing layers — all common in city neighborhoods — push that number toward the top of the range.
Slate repair and restoration runs $1,200 to $6,000 per section, and full slate replacement starts around $40,000. Low-slope rowhouse and porch roofs in modified bitumen or TPO run $9 to $15 per square foot installed.
Verify HICPA registration and insurance
Pennsylvania does not license roofers by trade, but the Home Improvement Consumer Protection Act requires contractors doing more than $5,000 of work per year to register with the Attorney General and show a PA registration number on contracts and advertising.
Check the number in the state's HICPA search, then require a certificate of insurance emailed from the carrier plus workers' compensation. On a steep Pittsburgh roof, comp coverage is not paperwork — it is the difference between their injury and your liability.
Old-house questions that separate the bids
Has the crew worked on slate, and are they proposing repair or replacement? A roofer who wants to strip sound slate for asphalt is solving their problem, not yours.
How many existing layers are coming off, and is the disposal in the bid? Two and three layers are routine here and change the tear-off price.
What is the plan for the valleys, chimney and box gutters? Built-in box gutters are a Pittsburgh signature and a very common leak source.
How is access being handled on a narrow city lot — staging, dumpster placement, and protecting the neighbor's property?
Timing and permits
April through October is the reliable installation window; shingles need warmth to seal and freeze-thaw is hard on a mid-winter install.
Reroofs in the city typically require a permit through Permits, Licenses and Inspections, pulled in the contractor's name. A contractor who asks you to pull it is a warning sign.

Common questions
How much does a new roof cost in Pittsburgh?
$10,500 to $18,000 for a standard asphalt shingle tear-off and replacement in 2026, with steep pitch, extra layers and third-story access pushing toward the top of the range.
Do Pittsburgh roofers need a license?
Pennsylvania has no roofing trade license, but contractors doing over $5,000 of work per year must hold a HICPA registration with the Attorney General and show the PA number on contracts.
Should I replace slate with asphalt?
Usually not if the slate is sound. Repair and restoration is cheaper per year of life, and swapping to asphalt can also affect a historic district review.
Who pulls the roofing permit?
The contractor should pull it in their own name through the city's Permits, Licenses and Inspections office. A request that you pull it yourself is a red flag.
