A new roof in Pennsylvania typically costs about $8,800 to $18,400 for 2,000 sq ft of asphalt shingle roof in 2026. The low end is This Old House’s Pennsylvania asphalt rate of $4.42 per sq ft; the high end is the Mid-Atlantic band in our 2026 roofing cost report. This Old House’s headline $7,489 average is real, but it prices a small roof of about 1,300 sq ft. Slate, standing seam metal, steep pitches and multi-layer tear-offs push Pennsylvania totals to $20,000 and beyond.
What moves a Pennsylvania quote is specific to the state: roofer wages almost exactly at the U.S. median, some of the oldest housing stock in the country, a statewide building code that moved to the 2021 International Residential Code on January 1, 2026, a sales tax rule that bars contractors from adding tax as a separate line, and a contract law (HICPA) that caps deposits.

Key numbers at a glance
These are the Pennsylvania figures most homeowners come looking for, each tied to a named source. They are typical ranges, not quotes: roof area, pitch, the number of layers coming off, deck condition and material decide where a specific house lands.

How much does a new roof cost in Pennsylvania?
A new roof in Pennsylvania usually runs about $8,800 to $18,400 for 2,000 sq ft of roof in asphalt shingles. This Old House’s Pennsylvania asphalt rate of $4.42 per sq ft sets the low end, and the Mid-Atlantic band in our 2026 cost report ($10,500 to $18,400, or 5% to 15% above the national baseline) sets the high end. Metal, slate and complex roofs cost more.
This Old House’s $7,489 average is easy to misread. Divide each of its Pennsylvania material totals by its per-square-foot rate and every one comes back to about 1,299 sq ft of roof: $5,740 divided by $4.42, $10,540 divided by $8.11 and $19,078 divided by $14.68 all land within one square foot of each other. That back-calculation is our arithmetic, not a figure This Old House prints, and 13 squares is a small ranch roof.
Remodeling magazine’s Cost vs Value 2025 report shows a much higher number for the Philadelphia market, $34,338, because it prices a different job: a 30-square (3,000 sq ft) roof torn off to the deck with new underlayment, flashing and two skylights. That works out to about $11.45 per sq ft, 7.7% above the report’s $31,871 national figure.

Pennsylvania roof cost by material
Asphalt shingles are the cheapest mainstream roof in Pennsylvania at $4.42 per sq ft in This Old House’s state data, against $8.11 for metal, $11.77 for wood, $14.61 for clay and $14.68 for slate. Scaled to 2,000 sq ft of roof, that is about $8,840 for asphalt, $16,220 for metal and $29,360 for slate, before any deck repair or extra layers.
| Material | This Old House PA, per sq ft | This Old House total (about 1,299 sq ft) | Implied total, 2,000 sq ft of roof | National installed range, per sq ft | Source |

The 2,000 sq ft column is our arithmetic, per-sq-ft rate times 2,000, and assumes a walkable pitch with one layer to remove. Slate and clay tile weigh far more than asphalt and often need a framing check.
Slate deserves its own line in Pennsylvania. The National Park Service’s history of Slateford Farm describes three historic Pennsylvania slate districts: Lancaster and York counties near the Maryland line, Lehigh County around Slatington, and Northampton County around Pen Argyl and Bangor. Many older Pennsylvania houses still carry slate, and a sound slate roof is often a repair job, not a replacement. Our slate roof repair cost guide and metal roof cost guide go deeper on both premium options.
Roof replacement cost by house size in Pennsylvania
This Old House’s Pennsylvania data runs from $6,972 for a 1,000 sq ft one-story home to $11,092 for a 3,000 sq ft two-story home. Those figures key off floor area, not roof area, which is why a two-story 2,000 sq ft house ($8,613) costs barely more than a one-story 1,500 sq ft house ($8,447): the two-story house has about half the roof per square foot of floor.
| Home size | This Old House PA total | Rough roof area (our estimate) | Architectural asphalt at $5 to $8 per sq ft |
|---|---|---|---|
| 1,000 sq ft, one story | $6,972 | About 1,150 to 1,300 sq ft | $5,750 to $10,400 |
| 1,500 sq ft, one story | $8,447 | About 1,725 to 1,950 sq ft | $8,625 to $15,600 |
| 2,000 sq ft, two story | $8,613 | About 1,150 to 1,300 sq ft | $5,750 to $10,400 |
| 2,200 sq ft, two story | Not reported | About 1,265 to 1,430 sq ft | $6,325 to $11,440 |
| 2,200 sq ft, one story | Not reported | About 2,530 to 2,860 sq ft | $12,650 to $22,880 |
| 2,500 sq ft, two story | $9,632 | About 1,440 to 1,625 sq ft | $7,190 to $13,000 |
| 3,000 sq ft, two story | $11,092 | About 1,725 to 1,950 sq ft | $8,625 to $15,600 |

Why Pennsylvania roofing labor costs about the national average
Pennsylvania roofers earn almost exactly the national norm. The median Pennsylvania roofer wage was $26.79 an hour in May 2025, 0.5% above the U.S. median of $26.65, and the mean of $27.15 sat 2.9% below the U.S. mean of $27.95, per BLS Occupational Employment and Wage Statistics. Pennsylvania employed about 3,830 roofers. Its neighbors are the outliers, not Pennsylvania.
| Area | Median hourly | Mean hourly | Roofers employed | Median vs Pennsylvania |
|---|---|---|---|---|
| Pennsylvania | $26.79 | $27.15 | 3,830 | Reference |
| United States | $26.65 | $27.95 | National total | Pennsylvania 0.5% higher |
| New Jersey | $36.83 | $35.76 | 1,860 | 37.5% higher than PA |
| New York | $31.74 | $33.34 | 4,570 | 18.5% higher than PA |
| Maryland | $28.89 | $29.63 | 2,050 | 7.8% higher than PA |
| Delaware | $28.58 | $26.58 | 230 | 6.7% higher than PA |
| West Virginia | $24.60 | $24.56 | 440 | 8.2% lower than PA |
| Ohio | $23.74 | $26.76 | 4,610 | 11.4% lower than PA |
Source: BLS OEWS, May 2025, SOC 47-2181 (Roofers), state and national estimates. Pennsylvania’s 10th percentile was $19.46 an hour and its 90th percentile $36.87. Our roofer salary by state report ranks Pennsylvania 24th on median pay, just above the national median.
Labor makes up roughly 40% to 60% of a reroof bill, the share Angi uses in its roof replacement cost guides. Applied to the wage gaps above, the arithmetic says a Pennsylvania job should price within a fraction of a percent of an identical U.S.-average job on labor alone, while the same job across the Delaware River in New Jersey could cost 15% to 23% more.
| Comparison | Wage gap (median) | Labor share assumed | Implied effect on total job cost |
|---|---|---|---|
| Pennsylvania vs U.S. average | +0.5% | 40% to 60% | +0.2% to +0.3% |
| New Jersey vs Pennsylvania | +37.5% ($36.83 vs $26.79) | 40% to 60% | +15.0% to +22.5% |
| New York vs Pennsylvania | +18.5% ($31.74 vs $26.79) | 40% to 60% | +7.4% to +11.1% |
| Ohio vs Pennsylvania | minus 11.4% ($23.74 vs $26.79) | 40% to 60% | minus 4.6% to minus 6.8% |
| Philadelphia metro vs Pittsburgh metro | +14.1% ($28.72 vs $25.17) | 40% to 60% | +5.6% to +8.5% |
| Altoona vs Philadelphia metro | minus 25.7% ($21.35 vs $28.72) | 40% to 60% | minus 10.3% to minus 15.4% |
This is a Roofing Brief estimate: wage gap times labor share. Real bids also reflect crew productivity, overhead, insurance and how busy contractors are, so treat the last column as direction and rough size, not a forecast. For labor-only pricing, see roofing labor cost per square.
Roof replacement cost by Pennsylvania metro
Within Pennsylvania, roofer pay runs from a median of $21.35 an hour in Altoona to $28.72 in the Philadelphia metro and $31.00 in Chambersburg, per BLS May 2025 metro estimates. Four Pennsylvania metros also rank among the 15 U.S. metros with the oldest housing, which raises the odds of extra layers, board sheathing and deck repair at tear-off.
| Metro | Roofer median wage (May 2025) | Roofers employed | Median vs Pennsylvania | Housing age signal |

| Philadelphia (Philadelphia-Camden-Wilmington) | $28.72/hr | 1,530 | +7.2% | Not in the oldest 15 |

What changes the price of a roof in Pennsylvania
Within the typical Pennsylvania range, a handful of state-specific factors move a bid: forced tear-off of slate or extra layers, deck repair on old houses, the ice barrier rule, the local labor market, Philadelphia’s permit conditions, Pennsylvania’s sales tax treatment of contractors and the spring and summer storm backlog. The table maps each driver to its usual effect, with the rule or number behind it.
| Driver | Effect on a Pennsylvania quote | Source |
|---|---|---|
| Two or more existing layers, or slate, clay, cement tile, wood shake or a deteriorated roof | Recover not allowed; full tear-off to the deck | 2021 IRC R908.3.1.1; Philadelphia L&I EZ re-roofing standard PB_012_F |
| Old house with spaced boards or rotten sheathing | Asphalt shingles need a solid deck, so replacement sheathing is added at $2 to $5 per sq ft installed | 2021 IRC R905.2.1; HomeGuide decking cost |
| Ice barrier at the eaves | Self-adhering membrane or two cemented underlayment layers, to 24 inches inside the exterior wall line, where the local climate table calls for it or the shingle maker requires it | 2021 IRC R905.1.2 and Table R301.2 |
| Metro labor market | Median roofer wage from $21.35 (Altoona) to $31.00 (Chambersburg) | BLS OEWS, May 2025 |
| Philadelphia: planned sheathing replacement over 10% of the roof, skylight cuts or more than 5% added load | Job leaves the EZ permit path and needs full plan review | Philadelphia L&I PB_012_F, revised 7/26 |
| Philadelphia: historic property | Philadelphia Historical Commission approval before an EZ permit | Philadelphia L&I PB_012_F |
| Philadelphia: roof insulation altered | New insulation to R-49 or greater under the 2021 IECC | Philadelphia L&I PB_012_F |
| Sales tax on materials | 6% state tax (7% in Allegheny County, 8% in Philadelphia) built into the price; contractors may not list it separately | 61 Pa. Code 31.12; Pa. Department of Revenue |
| Spring and summer storms | 84% of Pennsylvania’s 1-inch-plus hail reports fall in April to August, when crews book out | NOAA Storm Events, 2016 to 2025 |
| Deposit and payment terms | On contracts over $5,000, a deposit above one-third (plus listed special-order materials) is prohibited | 73 P.S. 517.9(10) |

Worked example: the same 2,000 sq ft roof in Pittsburgh and Philadelphia
The same architectural asphalt roof can cost roughly $600 to $1,500 more in Philadelphia than in Pittsburgh, by our estimate. Higher Philadelphia-metro roofer wages drive most of the gap; Philadelphia’s higher local sales tax and its EZ re-roofing permit add small amounts. Pittsburgh’s housing is older, though, so a Pittsburgh tear-off is more likely to uncover deck repair.
| Line item | Pittsburgh (Allegheny County) | Philadelphia | Basis |
|---|---|---|---|
| Architectural asphalt, 20 squares installed | $10,000 to $16,000 | $10,000 to $16,000 | $5 to $8 per sq ft, Roofing Brief 2026 baseline |
| Labor-market adjustment vs Pittsburgh | $0 (reference) | +$564 to $1,354 | Median wage +14.1% times 40% to 60% labor share, applied to the base |
| Local sales tax difference on materials | $0 (7% reference) | +$40 to $96 | One extra point (8% vs 7%) on a 40% to 60% material share |
| Permit | Set by Pittsburgh PLI; confirm scope before work | About $72 | PermitCalculator 2026 fee data for a $12,000 reroof, via our roof permit cost by metro report |
| Illustrative total, before any deck repair | $10,000 to $16,000 plus any permit fee | $10,676 to $17,522 | Sum of the rows above |
| If 5 sheets (160 sq ft) of decking need replacing | +$320 to $800 | +$320 to $800 | $2 to $5 per sq ft installed, HomeGuide |
This is a Roofing Brief estimate built from named inputs, not a quote. It assumes one existing layer, a walkable pitch and no structural work. The national baseline already contains an average amount of sales tax, so only the local difference is added. Fee figures come from our roof permit cost by metro report.
Do you need a permit to replace a roof in Pennsylvania?
Often yes, but your municipality decides. Pennsylvania’s Uniform Construction Code requires a permit to alter or repair a residential building and exempts an “ordinary repair,” and the code’s list of permit-free work does not name roofing (34 Pa. Code 403.62). So each building code official decides whether a like-for-like reroof needs a permit. Philadelphia issues a fast EZ re-roofing permit without plans.
The code those officials enforce changed on January 1, 2026. The Pennsylvania Department of Labor and Industry’s triennial update, approved by the Independent Regulatory Review Commission on October 16, 2025 and published in the Pennsylvania Bulletin on November 8, 2025, moved the Uniform Construction Code to the 2021 International Codes as amended. Philadelphia’s Code Bulletin B-2501 lists the 2021 International Residential Code among them and notes a transition rule: a permit can follow the code in effect when a design or construction contract was signed if the application is filed within six months of the new code’s effective date.
| Jurisdiction | Reroof permit rule | Contractor rule | Source |
|---|---|---|---|
| Commonwealth of Pennsylvania | Permit required to alter or repair a residential building; ordinary repairs exempt; roofing not on the exempt list, so the municipality decides | HICPA registration with the Attorney General if the contractor did $5,000 or more of home improvement work in the previous tax year | 34 Pa. Code 403.62; 73 P.S. 517.2 and 517.3 |
| Philadelphia | EZ re-roofing permit without plans for new coverings on existing roofs, if the job meets the standard’s conditions; inspector notified if damaged sheathing is found at tear-off | Roof certification completed by a licensed contractor, stating the work follows the manufacturer’s specifications | Philadelphia L&I, EZ Permit Standard PB_012_F, revised 7/26 (IRC-2021 / IBC-2021) |
| Pittsburgh | Ask the Department of Permits, Licenses and Inspections (PLI) whether your scope needs a permit; we did not find a published reroof exemption | Ask PLI which city license applies | City of Pittsburgh PLI |
| Other municipalities | Varies by local building code official or third-party inspection agency | HICPA applies statewide; some cities add local licenses | Ask the local code office before you sign |
Philadelphia’s EZ standard reads like a reroof specification, which makes it useful well beyond the city. It requires full tear-off over two or more layers or over slate, tile or wood shake; drip edge at eaves and gables extending at least 2 inches back on the deck; asphalt shingles only at slopes of 2:12 or steeper; shingles rated for wind under ASTM D7158 (class D, G or H) or ASTM D3161 (class A, D or F); and a Class B fire rating. It also allows sound existing slate, clay or cement tile to be reinstalled.
How Pennsylvania sales tax shows up in a roofing bid
In Pennsylvania, the roofer pays the sales tax, not you, and it should never appear as a separate line. Under 61 Pa. Code 31.12, a construction contractor pays tax on the materials it buys and “may include the tax he must pay in his bid proposal but not as a separately stated item.” The state rate is 6%, with 7% in Allegheny County and 8% in Philadelphia.
On a $12,000 asphalt job with materials at 40% to 60% of the bill, the embedded tax is roughly $288 to $432 at 6%, $336 to $504 at 7% and $384 to $576 at 8% (a Roofing Brief estimate: job cost times material share times rate). A bid that adds a separate sales tax line on a roof replacement deserves a question, because the regulation tells the contractor to fold it into the price.
| Location | Rate on contractor’s materials | Embedded tax on a $12,000 job (40% to 60% materials) | Source |
|---|---|---|---|
| Most of Pennsylvania | 6% | $288 to $432 | 61 Pa. Code 31.12; Pa. Department of Revenue |
| Allegheny County (Pittsburgh) | 7% | $336 to $504 | Pa. Department of Revenue local sales tax |
| Philadelphia | 8% | $384 to $576 | Pa. Department of Revenue local sales tax |
HICPA: what a Pennsylvania roofing contract must include
Pennsylvania’s Home Improvement Consumer Protection Act (73 P.S. 517.1 and following) makes a home improvement contract unenforceable against the owner unless it is written, includes the contractor’s registration number and meets a list of content rules. Roofs are named in the act’s definition of home improvement. It also gives you three business days to cancel and limits deposits on larger jobs.
| Rule | What it means for a Pennsylvania roof | Statute |
|---|---|---|
| Registration | Contractors with $5,000 or more of home improvement work in the previous tax year must register with the Attorney General; the registration number must be on the contract | 73 P.S. 517.2, 517.3, 517.7(a)(1) |
| Dates and scope | Approximate start and completion dates; a description of the work, materials and specifications that cannot change without a written change order signed by both sides | 73 P.S. 517.7(a)(6), (a)(7) |
| Price | A total price, or a time-and-materials estimate with a stated cap: costs may not exceed the estimate by more than 10% without a signed change order | 73 P.S. 517.7(a)(8) |
| Down payment | Any down payment and any advance for special-order materials listed separately | 73 P.S. 517.7(a)(9) |
| Deposit cap | On a contract over $5,000, no deposit above one-third of the price, or one-third plus special-order materials designated in the contract | 73 P.S. 517.9(10) |
| Insurance | The contractor agrees to carry at least $50,000 of personal injury and $50,000 of property damage liability coverage and states the current amount | 73 P.S. 517.7(a)(11); 517.4 |
| Subcontractors | Names, addresses and phone numbers of subcontractors known at signing | 73 P.S. 517.7(a)(10) |
| Three-business-day cancellation | You may rescind without penalty within three business days of signing; the Pennsylvania Supreme Court held on April 30, 2026 that actual notice by any medium, including orally, is enough | 73 P.S. 517.7(b); Office of Attorney General v. Gillece Services |
| Voidable clauses | You may void a contract containing a hold harmless clause, a waiver of building code requirements, a confession of judgment or a waiver of your rights under the act | 73 P.S. 517.7(e) |
The Attorney General’s online registration search confirms that a contractor is registered; it does not show complaints, so treat a registration number as a floor, not a recommendation. Our roofing contractor red flags list and storm-chaser contractors by state report cover the other warning signs.
How to price and hire for a Pennsylvania reroof
A comparable Pennsylvania bid starts with the same roof area, the same tear-off scope and the same contract terms from every contractor. The steps below follow the order a homeowner actually needs them, from measuring to final payment, and tie each step to the Pennsylvania rule that makes it matter.
- Measure the roof in squares. Count roof area, not floor area: a 2,200 sq ft two-story house may carry about 13 to 14 squares, a one-story house of the same size about 25 to 29.
- Find out what is on the roof now. Two layers, slate, tile or wood shake means a full tear-off under 2021 IRC R908.3.1.1, so every bid should price it.
- Check each contractor’s HICPA registration. Look the number up in the Attorney General’s registration search and make sure it matches the contract.
- Ask your municipality about the permit. In Philadelphia, ask whether the job fits the EZ re-roofing standard; elsewhere, call the local code office.
- Get three itemized bids. Ask for tear-off, a per-sheet decking price, ice barrier, drip edge, flashing and ventilation as separate lines, with no separate sales tax line.
- Check the contract against HICPA. Look for dates, specifications, the insurance statement, listed subcontractors and a deposit no larger than one-third on a job over $5,000.
- Use the three-day window if you need it. You may cancel within three business days of signing; put it in writing anyway so you have a record.
- Close out properly. Before final payment, get the permit final or Philadelphia roof certification, and confirm the shingle maker’s warranty registration.
Wind, hail and snow: Pennsylvania’s storm picture
Thunderstorm wind, more than hail, is Pennsylvania’s signature roof hazard. NOAA’s Storm Events Database logged 9,360 thunderstorm wind reports in Pennsylvania from 2016 to 2025, more than New York, Ohio, Maryland or New Jersey, against 920 reports of hail 1 inch or larger. Western Pennsylvania counties log the most hail, and May is the peak month.
| Storm measure, 2016 to 2025 | Pennsylvania | Ohio | New York | Maryland | New Jersey |
|---|---|---|---|---|---|
| Thunderstorm wind reports | 9,360 | 6,402 | 7,847 | 3,708 | 2,763 |
| Hail reports, all sizes | 1,308 | 1,584 | 775 | 388 | 356 |
| Hail 1 inch or larger | 920 | 1,027 | 561 | 352 | 215 |
| Hail 1.75 inches (golf ball) or larger | 140 | 165 | 88 | 60 | 15 |
| Tornadoes | 253 | 422 | 112 | 76 | 55 |
| Winter storm events | 852 | 654 | 1,168 | 358 | 321 |
| Heavy snow events | 210 | 97 | 510 | 14 | 50 |
| Lake-effect snow events | 135 | 104 | 624 | 0 | 0 |
| Ice storm events | 58 | 47 | 51 | 27 | 2 |

Inside Pennsylvania, 1-inch-plus hail clusters in the southwest: Allegheny County logged 98 reports, Butler 54, Westmoreland 49 and Washington 46. May alone holds 31% of the state’s 1-inch-plus reports, and April through August holds 84%. The busiest day was May 28, 2019, with 97 reports, and the largest stones on record in the period, 4.0 inches, fell in Northumberland County that day. Winter events concentrate in the northwest: Erie County’s forecast zones and Crawford County log the most winter storm, heavy snow and lake-effect snow events in the state.
For a roof, that profile points to wind-rated shingles and fastening first, and to ice barriers at the eaves in snow country. Philadelphia already requires the shingle wind classes listed in its EZ standard. Our hail damage claims by state report puts Pennsylvania’s hail exposure in national context.
How insurance treats an older Pennsylvania roof
A standard homeowners policy may pay for wind or hail damage from a covered storm but usually not for wear and tear, and some policies settle older roofs at actual cash value, which subtracts depreciation. On a 20-year-old asphalt roof, depreciation can take a large share of the payout. Check your declarations page for the wind and hail deductible and the roof settlement basis before storm season.
On a typical HO-3 policy the dwelling is covered on an open-perils basis, so a covered wind loss to the roof is not limited by a named-peril list; exclusions and the settlement terms decide what you collect. Insurers also weigh roof age when they underwrite or renew, which our roof age and non-renewal report tracks across states, and our actual cash value roof guide shows how depreciation is figured. If a Pennsylvania claim stalls, the Pennsylvania Insurance Department takes consumer complaints.
Code items are a common sticking point after a claim. Drip edge, ice barrier and solid sheathing are code requirements on a reroof under the 2021 IRC, and an ordinance or law endorsement, if your policy has one, may help pay for code-required work. A roofing contract signed before the adjuster’s decision is still subject to HICPA’s three-business-day cancellation right.
Slate, metal or asphalt: which should a Pennsylvania homeowner pick?
For most Pennsylvania homes, architectural asphalt is the lowest-cost replacement and the best resale bet: Cost vs Value 2025 puts asphalt’s cost recouped in the Philadelphia market at 66.5% against 41.4% for metal. Metal suits owners staying for decades, and sound original slate is usually worth repairing rather than replacing.
| If your situation is | Then consider | Why | Source |
|---|---|---|---|
| Original slate in sound condition with some broken or missing pieces | Slate repair, not replacement | Slate cannot be covered over, and sound slate can be reinstalled in Philadelphia; replacement slate runs $15 to $30 per sq ft | 2021 IRC R908.3.1.1; Philadelphia PB_012_F; TRB 2026 cost report |
| Asphalt roof at end of life, selling within about five years | Architectural asphalt | Lowest cost and the higher share recouped at resale | This Old House PA; Cost vs Value 2025, Philadelphia |
| Staying 25 years or more, snow country or a simple roof shape | Standing seam or exposed-fastener metal | About 1.65 to 1.83 times asphalt up front, with a longer service life | Cost vs Value 2025, Philadelphia; This Old House PA |
| Rowhouse or addition with a low-slope roof | Membrane (TPO, EPDM or modified bitumen) | Asphalt shingles are allowed only at slopes of 2:12 or steeper | 2021 IRC R905.2.2; Philadelphia PB_012_F |
| Property in a Philadelphia historic district | Get Historical Commission approval before choosing material | The EZ permit path does not apply without prior approval | Philadelphia PB_012_F |
| Two existing asphalt layers | Budget for full tear-off and possible deck repair | A third layer is not permitted; decking runs $2 to $5 per sq ft | 2021 IRC R908.3.1.1; HomeGuide |
Our slate vs metal roof comparison and roof lifespan guide cover the long-run math, and the flat roof replacement cost guide covers low-slope systems.
Programs and tax credits for a Pennsylvania roof
We found no standing statewide roof grant in Pennsylvania, and federal homeowner energy credits do not help with a 2026 roof. The state’s Whole-Home Repairs Program, a $120 million program run by the Department of Community and Economic Development through county agencies, funded habitability and safety repairs for owners at or below 80% of area median income, so ask your county whether funds remain.
The Governor’s office announced the first county payments on March 10, 2023. The program was built on one-time funding, so availability now varies by county. On the federal side, a standard asphalt or metal roof did not qualify for the 25C credit after 2022, and Public Law 119-21 ended 25C for property placed in service after December 31, 2025, and the 25D residential clean energy credit for solar installed after that date. Check current IRS guidance and a tax professional before counting on any credit.
How Pennsylvania compares with its neighbors
Pennsylvania sits in the middle of its region on roofing cost. Labor alone would put an identical job about 15% to 23% higher in New Jersey and about 5% to 7% lower in Ohio, by our wage arithmetic. Our state guides break out each neighbor’s own code, permit and contract rules.
- Roof replacement cost in New Jersey: the highest roofer wages in the region and its own permit exemptions.
- Roof replacement cost in New York: wages about 18.5% above Pennsylvania’s median.
- Roof replacement cost in Ohio: the lower-wage neighbor to the west, with heavier hail counts.
- Roof replacement cost in Maryland: MHIC licensing and wages about 7.8% above Pennsylvania’s.

Frequently asked questions
Will insurance cover a 20-year-old roof?
Often yes for sudden storm damage, but rarely in full. A homeowners policy may pay for wind or hail damage from a covered event, not wear and tear, and many policies settle older roofs at actual cash value, which subtracts depreciation. On a 20-year-old asphalt roof that can cut the payout sharply. Check your declarations page for the roof settlement basis and the wind and hail deductible.
Do I need a permit to replace a roof in PA?
Often, but your municipality decides. Pennsylvania’s Uniform Construction Code requires a permit to alter or repair a residential building, exempts ordinary repairs, and does not list roofing among permit-free work (34 Pa. Code 403.62). Philadelphia issues an EZ re-roofing permit without plans when the job meets its standard. Elsewhere, ask the local building code official before work starts.
How much does it cost to replace a roof on a 2,200 square-foot house?
In Pennsylvania, about $6,300 to $11,400 for a two-story 2,200 sq ft house and about $12,700 to $22,900 for a one-story house, in architectural asphalt at $5 to $8 per sq ft. The difference is roof area: roughly 13 to 14 squares on the two-story house versus 25 to 29 on the ranch. Mid-Atlantic pricing can add 5% to 15%.
Is it cheaper to replace a roof with shingles or metal?
Shingles are cheaper up front. This Old House’s Pennsylvania data puts asphalt at $4.42 per sq ft and metal at $8.11, and Remodeling’s Cost vs Value 2025 prices a 3,000 sq ft Philadelphia job at $34,338 in asphalt versus $56,652 in metal. Metal lasts longer, so it can cost less per year of service if you stay in the house for decades.
What is the 25% rule for roofing?
The 25% rule comes from Florida, where the building code once required replacing a whole roof section when more than 25% was repaired within 12 months; Florida’s 2022 law (SB 4-D) narrowed it. Pennsylvania’s code, the 2021 IRC as amended, has no such rule. Whether an insurer replaces a full slope for matching depends on your policy wording, not the building code.
Is $30,000 too much for a roof?
For a typical Pennsylvania asphalt roof, usually yes: 2,000 sq ft of roof runs about $8,800 to $18,400. But $30,000 can be fair for natural slate (This Old House implies about $29,360 for 2,000 sq ft), standing seam metal, or a large roof: Cost vs Value 2025 prices a 3,000 sq ft Philadelphia asphalt tear-off at $34,338. Ask for an itemized bid.
How much should a 1,500 sq ft roof cost?
If 1,500 sq ft is the roof area (15 squares), architectural asphalt runs about $7,500 to $12,000 at $5 to $8 per sq ft, or about $6,630 at This Old House’s Pennsylvania rate of $4.42. If 1,500 sq ft is a one-story house’s floor area, the roof is closer to 1,725 to 1,950 sq ft, or about $8,625 to $15,600.
Should a 20-year-old roof be replaced?
Not automatically. Age is a planning signal, not a verdict: InterNACHI estimates about 20 years for three-tab asphalt and 30 for architectural shingles, while slate can last far longer. Replace when an inspection finds widespread granule loss, curling, cracked or missing shingles, soft decking or repeated leaks. In older Pennsylvania houses, check for slate worth repairing before pricing a tear-off.
