A planning estimate only, based on typical Knoxville-area prices. Real quotes depend on your roof's layout, layers, decking and access.

How the estimate works

Roofers price by the "square", which is 100 square feet of roof surface. We estimate your roof surface from your home's footprint (heated square feet divided by the number of stories), add room for eaves and overhangs, and adjust for how steep the roof is. An attached garage adds its own roof area.

We then multiply by a typical installed price range for the material you picked. Installed prices include tear-off of one layer, underlayment, flashing, ridge vents and cleanup in most quotes, but always check what each quote includes.

What pushes a quote up or down

  • Layers to remove. A second layer of old shingles means more labor and disposal.
  • Rotten decking. Soft or damaged plywood is usually priced per sheet once the old roof is off.
  • Roof shape. Valleys, dormers, skylights and chimneys add flashing work and waste.
  • Steepness and height. Steep or tall roofs need extra safety gear and go slower.
  • Material and warranty tier. Upgraded shingle lines and longer manufacturer warranties cost more.
  • Insurance. If storm damage is covered, your out-of-pocket cost may be closer to your deductible.

The only way to know your real price is to get written quotes. Comparing two or three of them also shows you quickly if one roofer is far out of line.

COMMON QUESTIONS

Roof Cost Calculator Questions

How accurate is the roof cost calculator?

It gives a planning range, not a quote. Two homes with the same square footage can have very different roofs. Use the range to budget and to sanity-check the written quotes you get.

What is a roofing square?

A square is 100 square feet of roof surface. A typical Knoxville-area house has somewhere between 15 and 35 squares depending on its size, number of stories and pitch.

Does homeowners insurance pay for a new roof?

Insurance usually covers sudden damage such as hail, wind or a fallen tree, not old age or wear. If a storm damaged your roof, have it inspected and document everything before you file a claim.
