Roof Replacement Cost in Knoxville
Roofs are priced by the square, not the house. Here is what a square costs, and the four things that decide how many you need.
A roofing square is 100 square feet. Everything starts there.
Roofers price in squares because that is how material ships and how labor gets estimated. A common Knoxville ranch might be 20 to 25 squares. Once you know roughly how many squares you have, the per-square figures below turn a vague worry into a range you can plan around.
These are national market ranges, not our price. Pitch, layers, decking condition and material choice are what move a specific roof inside them.
By material
| Material | Typical market range |
|---|---|
| Asphalt shingle, installedThe default in East Tennessee | $3–$5 / sq ft |
| Asphalt shingle, typical home totalStandard 3-tab composition | $5,700–$12,000 |
| Metal roofing, installedWide span across profiles and gauges | $4–$30 / sq ft |
| Roofing material only, asphaltPer square, which is 100 sq ft | $80–$250 |
Asphalt replacement runs $5,700 to $12,000 on a typical home nationally, per the Angi and HomeGuide 2026 cost guides. Those are national market ranges rather than our price — a specific estimate comes from measuring your roof.
What actually moves the number
- Pitch. A walkable roof and a steep one are different labor entirely. Past a certain pitch the crew needs staging and fall protection, production slows, and the same square footage costs more to cover.
- Layers. Tearing off one layer is routine. Tearing off two or three doubles or triples the disposal and the labor before a single new shingle goes down.
- What the tear-off finds. Soft decking, rotted fascia and failed flashing are not visible from the ground and are common on East Tennessee roofs that have taken a decade of humidity. Honest bids carry a decking allowance rather than pretending the deck is perfect.
- Complexity. Valleys, dormers, chimneys, skylights and multiple roof planes all add cut time and flashing detail. Two roofs with identical square footage can differ substantially on complexity alone.
Cost questions, answered
What is a roofing square?
100 square feet of roof surface. Material ships by the square and labor is estimated by the square, which is why roofers price that way instead of by the house.
Is metal worth the premium over asphalt?
Metal runs $4 to $30 per square foot against asphalt's $3 to $5 installed, per the 2026 national cost guides. The case for metal is service life rather than up-front price.
Why do bids on the same roof differ?
Usually tear-off scope, decking allowance and flashing detail rather than the shingle itself. Ask each bid what happens when the tear-off finds bad decking, and the bids become comparable.
Will insurance cover a storm-damaged roof?
Storm damage claims are common in this region. Coverage depends on your policy and the adjuster's finding, so it is worth documenting the damage before any work begins.
