Roof Replacement Permit Rules in 10 US Cities

Whether a new roof needs a permit depends far more on your city than on the size of the job. Some cities treat a like-for-like shingle swap as maintenance; others require a permit for any re-roof. Here is what each city's own rules say.

Key Takeaways

  • A like-for-like shingle swap is exempt in Austin, Seattle (detached 1–2 family), Baltimore (1–2 family) and Raleigh (under the NC $40,000 rule).
  • Chicago, Los Angeles, Philadelphia, Orlando and Nashville (over one-third of the roof) require a permit for a re-roof.
  • Replacing roof decking or rafters changes the answer almost everywhere.
  • Los Angeles adds a cool-roof requirement when more than half of a roof is replaced.
  • Ask your roofer who pulls the permit and whether the fee is in the quote.

Cities Where a Re-Roof Usually Needs a Permit

Chicago handles roof repair, recovering and replacement through its Express Permit Program, and the work must be done by an Illinois-licensed roofing contractor. Los Angeles issues re-roofs as Express Permits without plan check, and replacing more than half of a roof triggers the city's cool-roof requirement. Philadelphia requires a building permit for roof covering replacement, issued as an EZ permit with no plans. Orlando requires a building permit for residential re-roofs, with a dry-in inspection before the final.

Nashville requires a permit to add roofing or replace more than one-third of a roof; repairs up to 33% of the roof area are treated as normal maintenance.

Cities Where a Like-For-Like Re-Roof Is Often Exempt

Austin exempts asphalt shingles replacing asphalt shingles, but a permit is required to replace more than 128 sq ft of roof decking, or when 50% or more of a roof in the Wildland-Urban Interface is replaced. Seattle needs no permit for detached one- and two-family homes when the re-roof does not change the building envelope. Baltimore lists replacing roof shingles on one- and two-family homes as work exempt from permit. Raleigh follows North Carolina law, which exempts roofing replacement on a project costing $40,000 or less. In New York City, replacing roof coverings above the roof deck can be an ordinary repair, but replacing the deck or sheathing requires a permit.

The Common Trigger: Structure, Not Shingles

Across the ten cities compared here the pattern is the same: work on the covering is treated lightly, while work on the roof deck, rafters or the building envelope brings a permit. If your roofer finds rotten sheathing halfway through the job, the permit question can change. Ask before work starts who will pull a permit if decking has to be replaced.

What to Ask Your Roofer

  • Will this job replace any roof decking, and how much?
  • Who pulls the permit, and is the permit fee in the quote?
  • Does my city require a licensed roofer for this work?

Roof Permit Pages by City

Each city page shows the official rule, the source, and how many roof permits the city issued in the last 12 months: Chicago Roofing Permits, Austin Roofing Permits, Orlando Roofing Permits and Philadelphia Roofing Permits. For every city in one place, see Roofing Permits by City.

Before You Sign a Roofing Contract

Roofing is the trade where the permit question most often comes up mid-job, because rotten decking is only found once the old covering is off. Agree in writing what happens if decking must be replaced: who decides, how it is priced, and who applies for any permit that becomes necessary. In Orlando a Notice of Commencement is also required for jobs over $5,000; Orlando Roof Permit Process: Notice of Commencement and Owner-Builder Steps walks through the paperwork. If you are unsure whether the work is permitted, look the address up afterwards; How to Look Up Building Permits for a House shows how.
