Roofing Permits in Allentown, PA
Roof work here answers to two things: what the adopted code requires of the roof, and what credential the roofer must hold. The code is Pennsylvania Residential Code 2021, which adopts the IRC 2021 with state amendments. The adopted edition sets the reroofing rules a tear-off has to meet, so it is not carried across from a neighbouring state. See what a replacement costs here and the area overview.
Key numbers for Allentown
What follows is drawn from the permitting authority’s own published rules for Allentown, PA. Every figure links to its source.
Registration turns on turnover, not on the job
Pennsylvania requires Home Improvement Contractor registration from anyone doing at least $5,000 of home improvements a year, and roofing is named in the covered work. The threshold is annual turnover, not the size of your job, so a roofer working on your house full time is certainly covered.
The registration number has to appear on the contract. A roofer who cannot give you one is either under $5,000 a year in total — which is worth knowing on its own — or is not registered.
What forces a full tear-off
Two layers is the ceiling: where a roof already carries two applications of any covering, the code bars adding a third and the old ones have to come off.
The same code bars a re-cover altogether where the existing roof is water soaked or too deteriorated to serve as a base, and over slate, clay, cement or asbestos-cement tile. So the layer count is not the only thing that can force a full tear-off — the condition of what is already up there can force one on its own, and that is not knowable from the ground.
What needs a permit in Allentown

What licence a roofer needs here
- Whether a roofing-specific license is required SOURCED
- Registration rather than a licence, and roofing is explicitly covered. Pennsylvania requires anyone performing at least $5,000 of home improvements a year to register as a Home Improvement Contractor with the Office of Attorney General, and the construction, replacement, installation or improvement of roofs is named among the covered work. Contractors doing under $5,000 a year are exempt, as are very large retailers. attorneygeneral.gov
- Licensing authority SOURCED
- Pennsylvania Office of Attorney General, Home Improvement Contractor registration under the Home Improvement Consumer Protection Act. attorneygeneral.gov
- Roofing license or registration fee SOURCED
- $100 for a two-year registration. attorneygeneral.gov
- Where a homeowner can verify a license SOURCED
- The Attorney General publishes a public Home Improvement Contractor search. The registration number must appear on the contract; a roofer who cannot give you one is either exempt as a sub-$5,000-a-year operation or is not registered. hicsearch.attorneygeneral.gov
How long it takes
- Typical weather-driven scheduling constraint SOURCED
- 42 days a year have a normal daily high below 40F at Lehigh Valley International Airport, concentrated in January (NOAA NCEI 1991-2020 daily normals). Asphalt shingles rely on warmth to seal their tabs down, so that is the part of the calendar where a re-roof either waits or is installed knowing the seal will not set until spring. It is the practical reason a cold-climate re-roof gets scheduled rather than booked for the next free slot. ncei.noaa.gov
- Peak roofing season locally SOURCED
- Every month outside January has a normal daily high of 40F or above (NOAA NCEI 1991-2020 daily normals). Expect the middle of that window to be the busiest and the hardest to book, and expect quotes taken in it to reflect that. ncei.noaa.gov
