The city permit, in full
Inside Knoxville city limits, a re-roof needs a building permit from the City of Knoxville Plans Review and Permits office (permits.knoxvilletn.gov), and an inspection after tear-off. The only exemption is an overlay, where a second layer goes over a first layer that's intact.
We price Knoxville replacements as tear-offs, so the permit shows up on your price as its own line. The tear-off inspection works in your favor. A city inspector sees the bare decking before anything covers it.
If a roofer offers to skip the permit by laying shingles over what you have, ask how many layers are already up there. On a lot of older Knoxville houses the answer is two or three.

Fourth and Gill and the older north side
Fourth and Gill and Old North Knoxville are full of older homes with steep roofs, and many of them carry two or three layers of shingles. All of it comes off. After decades under that much weight, the decking usually needs some boards replaced. Your price should say what each board costs before tear-off starts.
Both neighborhoods are city historic districts. There, a new roof needs approval from the city's historic zoning staff first, called a certificate of appropriateness. That review can shape what you're allowed to put on, so we check what the district asks for before we price the job and build the wait into the schedule.
The 1990s subdivisions
Roofs from Knoxville's 1990s subdivisions usually have one layer, sheet decking and a simple shape, so the real question is how much life the shingles have left. Granules piling up at the downspouts and shingles that crack when you lift a corner both point to a roof near its end.

Hail and a tornado in the county
WBIR reported hail as large as 1.5 inches across Knox County on September 4, 2025. On August 7, 2023, the National Weather Service office in Morristown confirmed an EF-2 tornado in the county. Hail bruises tend to hide on the back slopes nobody sees from the street, so after a storm like either one, get the whole roof looked at before you decide whether to file a claim.
Common questions
Do I need the city permit if my address says Knoxville?
Not always. The city permit applies inside Knoxville city limits, and some homes with a Knoxville mailing address sit outside them, in unincorporated Knox County. Out there, the county's codes office sets the rules. Give us the address and we'll tell you which office applies before we price the job.
Can you re-roof a house in a historic district?
Yes. In Fourth and Gill and Old North Knoxville, the city's historic zoning staff reviews a new roof before work starts. We find out what that review will want to see, and we plan the schedule around the wait so the permit and the materials line up.
Do you pull the permit?
Yes. Inside Knoxville city limits a re-roof needs a city building permit and an inspection after tear-off. Farragut, Maryville, Oak Ridge and the counties set their own rules; Farragut, for example, says a plain re-roof usually doesn't need one. We check the rule for your address and pull the permit when one is needed.
Why are there black streaks on my roof?
That's almost always algae. Knoxville gets about 52 inches of rain a year and stays humid all summer, and algae grows on shady, north-facing slopes. It's mostly cosmetic. Pressure washing strips granules and shortens the roof's life, so don't. When you replace, an algae-resistant shingle keeps it away longer.
