Price Ranges by Material
These are the five figures we use on every page of this site, each with its source and year. None of them is a quote. Sources differ because they assume different roof sizes, materials and tear-off, so a statewide job average and a per-square-foot rate can't be lined up one against the other.
| Cost row | Figure | Source (year) |
|---|---|---|
| Tennessee re-roof, average | about $8,518 (range $6,703–$20,071) | This Old House, 2026 |
| Tennessee architectural shingles, per sq ft | about $5.05 | RoofObservations, 2026 |
| Tennessee impact-resistant shingles, per sq ft | about $6.25 | RoofObservations, 2026 |
| Tennessee exposed-fastener steel, per sq ft | about $8.45 | RoofObservations, 2026 |
| Knoxville re-roofing, per sq ft | about $7.36 | ContractorPlus, 2026 |
The This Old House row prices a whole job across Tennessee. The other four are rates per square foot of roof surface. Architectural shingles sit lowest, impact-resistant shingles come next and exposed-fastener steel costs more than either. Only the ContractorPlus row is specific to Knoxville. Read them as signposts for a budget, not as the price of your roof.
Why Two Roofs Cost Differently
Two houses on the same street can get very different estimates. These are the main reasons.
- Roof surface, not floor space. You pay for the area of the roof itself, which grows once slope and overhang are counted. A bigger home usually means a bigger roof.
- How steep it is. A steep roof covers more surface over the same footprint and is harder to work on safely than one you can walk.
- The material. Shingles cost less per square foot than metal. Within shingles, Class 4 impact-resistant lines cost more than standard architectural ones.
- Tear-off and decking. Removing the old roof and replacing any soft decking found underneath adds labor and disposal to the bill.
- Number of stories. For the same living space, a two-story house sits on a smaller footprint, so it usually has less roof than a one-story house.
- Historic overlays. In districts such as Fourth and Gill, Old North Knoxville, Mechanicsville and Edgewood-Park City, a roof material change goes to the Historic Zoning Commission. That review is an extra step to plan for.
Our cost calculator turns those factors into a range. It uses planning rates per square foot of roof: $4.50 to $7.50 for shingles, from architectural shingles up to Class 4 jobs, and $8.25 to $13.50 for metal, from exposed-fastener steel up to standing seam. Here is the worked example, step by step.
- Home size. Choose "1,500 to 2,000". The calculator uses 1,750 sq ft for that band (1,250 for under 1,500, then 2,250, 2,750 and 3,250 for the larger bands).
- Stories. Choose "One story". The size is divided by the number of stories (1, 1.5 or 2), so the footprint stays at 1,750 sq ft.
- Steepness. Choose "Walkable", a slope factor of 1.12 (steep is 1.30). Every roof also gets 1.10 for the overhang: 1,750 × 1.12 × 1.10 = 2,156, rounded to 2,160 sq ft of roof.
- Material. Choose "Shingles". The low end is 2,160 × $4.50 = $9,720, rounded to $9,700. The high end is 2,160 × $7.50 = $16,200.
So that home's estimate reads about $9,700 to $16,200. It sits above the This Old House average of $8,518 but inside its $6,703–$20,071 range, which is what you'd expect for a full tear-off on a roof of that size.
Comparing Estimates Fairly
If you set the roofer's estimate beside another one you've gathered yourself, make sure both price the same job. A low number that skips tear-off or names a cheaper shingle isn't a better deal, just a different roof.
- The same roof area. Both estimates should measure roughly the same square footage. A large gap is worth asking about.
- The named product. Look for the exact shingle or metal panel, the underlayment and whether tear-off is included.
- An itemized, written contract. Labor, materials, disposal and any decking allowance should each be listed.
- Written warranties. Ask for both the manufacturer warranty and the roofer's labor warranty on paper.
- Proof of insurance, a local address and references. These are fair things to ask any roofer for.
The license depends on the size of the job. In Knox County, Tennessee treats roofing as home improvement, so a roofer needs a state Home Improvement license for residential jobs from $3,000 to $24,999 and a state contractor license at $25,000 or more. Check either one at verify.tn.gov. A permit for home improvement work must list the contractor's Home Improvement license number.
Your roofer handles any permit. Ask whether yours needs one and confirm with City of Knoxville Plans Review and Inspections at (865) 215-4311 inside city limits, or Knox County Codes Administration at 865-215-2325 for unincorporated addresses. On payment, the Tennessee Attorney General advises paying no more than one-third up front.
When Insurance Pays
When a storm caused the damage, your homeowners policy may pay for part of a new roof. A roofer can photograph and write up what they find on the roof. Filing and settling the claim is a matter between you and your insurance company. We play no part in claims, and Tennessee law bars roofers from acting as public adjusters.
Tennessee adds rules for roofing contracts paid by insurance. Before you sign, the roofer must give you its address, phone number, license numbers, a detailed description of the damage and repairs, and a bold notice of your right to cancel. If your insurer says in writing that all or part of the claim isn't covered, you can cancel until midnight of the third business day after you receive that notice.
The roofer also can't require payment until your insurer confirms coverage in writing or that three-day window has passed, apart from emergency repairs you approved in writing. After a cancellation, any refund is due within 10 business days. Don't sign over the whole insurance check before the work is done.
Your deductible is yours to pay. A roofer who offers to cover or waive it is showing you a warning sign. If you're choosing Class 4 shingles or a FORTIFIED roof, ask your insurer whether either one lowers your premium before you sign. Some insurers offer a discount and some don't.
