What Each Material Costs

This guide has no Kennesaw-only figure, so the rows below come from regional and statewide cost guides. They are estimates, not quotes, and the only number that counts is the one in your roofer's written estimate.

These sources disagree, and that's expected: they assume different roof sizes and materials. A whole-job average reflects whatever roof size the source had in mind, while a per-square-foot figure lets you scale the price to your own roof. Read the rows as a band to measure an estimate against, not a single correct answer.

Our cost calculator turns those rows into a range for your house. It uses $4.50 to $8.50 per square foot of roof surface for shingles, from architectural at the low end to Class 4 jobs at the high end, and $8.00 to $14.50 for metal, from basic panels to standing seam with tear-off.

Here's how it works on a sample home. A one-story house of about 1,750 square feet with a walkable roof has a footprint of 1,750 square feet. Multiply by 1.12 for the slope and 1.10 for the overhang, and the roof surface comes to about 2,160 square feet. At the shingle rates, that's roughly $9,700 to $18,400.

Price Drivers Explained

The median owner home in Kennesaw is valued at $335,400 (Census QuickFacts), and roofs on homes in that range vary widely in size and shape. These are the things that move the number most.

  • Roof surface, not floor space. The calculator divides your home's size by its stories to get the footprint, then adds slope and overhang. A one-story house carries more roof than a two-story house of the same size.
  • Steepness. A walkable roof uses a slope factor of 1.12 in our calculator; a steep roof uses 1.30. More surface means more material and more labor.
  • Material. Shingles run $4.50 to $8.50 per square foot in the calculator and metal $8.00 to $14.50. The Georgia standing-seam steel, per sq ft row above is about $11.50.
  • Class 4 and FORTIFIED upgrades. Class 4 impact-resistant shingles push a shingle job toward the top of its range. Both are options, not requirements in Kennesaw.
  • What turns up at tear-off. Soft or damaged decking only shows once the old roof is off. Ask how the estimate handles it before you sign.
  • Permits and local review. Your roofer pulls any permit. This guide lists no permit fee. In the historic district, check with Planning & Zoning (770-424-8274) before changing roof material or color.

What to Look For on Paper

Two estimates for the same roof can look far apart until you compare them line by line. Georgia doesn't license roofers at the state level, so the paperwork is also where you check who you're dealing with.

  • An itemized, written contract. Materials, tear-off, labor and cleanup each on their own line, with the shingle or panel named.
  • Insurance certificates. Ask for general liability and workers' comp certificates, plus a local business license.
  • Written warranties. Get both the manufacturer warranty and the roofer's labor warranty in writing.
  • Who pulls the permit. The contract should say the roofer does. Inside city limits that's City of Kennesaw Building Services, (770) 429-4554; in unincorporated Cobb County, Cobb County Community Development, (770) 528-1000.
  • A fair payment schedule. Avoid cash-only deals and any request for full payment up front.
  • A local address and references. Call a couple of past customers before you commit.

Insurance-Covered Replacements

When storm damage is involved, a roofer can photograph and measure the damage; you and your insurer settle the claim. This site never handles claims and doesn't talk to insurers for you.

You pay your own deductible. The Georgia Attorney General says roofers may not pay or cover it, and an offer to do so is a warning sign worth taking seriously.

If you're choosing materials anyway, many insurers offer a discount for a Class 4 or FORTIFIED roof; ask yours before you decide, and get the answer in writing. Georgia's other rules for insurance-paid roofing contracts are on the Georgia roofing rules page.
