What a New Roof Costs in Pennsylvania
Nobody can price a roof without measuring it, and no public source gives a Pennsylvania price. What the code adds to a replacement here, what the permit costs, and the figures public records do give, are below.
New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.
This number connects homeowners who are planning a new roof or a full roof replacement with independent local roofing contractors. It is not for leak repairs or patch jobs. The call must come from the homeowner who decides on the roof. Calls may be recorded.
What public records say
In 2025 the City issued 2,334 EZ permits for roof covering replacement. ZIP 19143 had the most, 191, followed by 19145 (138), 19140 (129), 19132 (117) and 19120 (107); 19127 had 3. The permit table carries no job values, so it says how many roofs were replaced, not what they cost (OpenDataPhilly, L&I permits).
The table counts permits, not prices. Roof replacement in Philadelphia.
Price ranges on other sites for towns in Pennsylvania are modeled from national averages. This site does not print a price it cannot source; the written estimate from a contractor who has measured the roof is the number that counts.
What moves the price in Pennsylvania
01 · Tear-off or recover
A new roof may go over one existing layer only. Where the roof already has two or more layers, where the old covering is slate, clay or cement tile, or where it is water-soaked or deteriorated, everything comes off to the deck first. (IRC R908.3.1.1, part of the 2021 code Pennsylvania adopted.)
02 · The deck under the shingles
Rotted or damaged sheathing found at tear-off is replaced by the sheet. Ask how the quote prices it: per sheet, or included up to a number of sheets. Philadelphia’s reroof certification (form TP_019_F) asks the contractor whether less than 10% of the sheathing was replaced.
03 · Underlayment
On asphalt shingles at a slope from 2:12 up to 4:12, the code requires a double layer of underlayment (IRC R905.2.2); low-pitched roofs cost more to cover for that reason.
04 · Ice barrier
The code requires an eave ice barrier where the local climate table (Table R301.2) says so, and in Pennsylvania each municipality fills in that table when it adopts the code. Ask your township or borough code office, or the contractor, whether the table marks your area “yes.”
05 · Permit
Pennsylvania’s Uniform Construction Code does not apply to “alterations to residential buildings which do not make structural changes” (34 Pa. Code § 403.1(b)(8)), so whether a reroof needs a permit is set by your municipality’s own ordinance. Call its code office before the work starts. In Philadelphia the EZ permit for a one- or two-family house is $69.
06 · Material
HUD’s useful-life table gives asphalt shingles 20 years, metal 50, slate 75, clay or concrete tile 60 and EPDM or TPO 15. The spread in price between materials is wider than any other line on a quote.
07 · Access and the house
Stories, pitch, dormers and skylights, and on rowhouses the party walls and the way up, all add labor. Ask the contractor to list them.
Floor area is not roof area
A 2,000-square-foot house does not have a 2,000-square-foot roof. Pitch, overhangs, a second story over part of the house, porches and dormers all change it, which is why a contractor measures before quoting.
Tax credit and payment
The federal energy-efficient home improvement credit (25C) does not list roofs, and it ended for property placed in service after December 31, 2025 (IRS). If a contractor offers to arrange payment over time, get the APR and the total cost in writing before you sign.
