Material-by-Material Prices

Two estimators publish numbers for this area. This Old House covers Kentucky as a whole, and HomeBlue looks at Louisville in particular. Both are installed prices for a replacement, not material alone.

Why don't the sources agree exactly? Each one assumes a different roof size, a different mix of materials and a different amount of tear-off, so treat them as guide rails rather than a quote. The per-square-foot rows are the easiest to use: multiply by your roof's surface area, not your home's floor area. Roofers often talk in "squares," and one square covers 100 square feet of roof.

Our cost calculator turns those rows into a working range. It uses $4.00 to $6.75 per square foot for shingles and $7.00 to $11.50 for metal. Plug in a single-story home in the 1,500 to 2,000 band (the tool uses 1,750) with a roof you could walk on, and it estimates about 2,160 square feet of roof surface, which comes to about $8,600 to $14,600 in shingles or $15,100 to $24,800 in metal.

Why Two Roofs Cost Differently

Two houses on the same street can get very different quotes. In Jefferson County, KY, 62.1% of homes are owner-occupied, with a median owner value of $248,400, so plenty of neighbors are comparing numbers. These are the usual reasons the figures split apart.

  • Roof area. A one-story ranch spreads its floor area under one big roof, so it often has more roof than a two-story house of the same size.
  • Pitch. A steep roof takes harnesses, roof jacks and slower work. The calculator adds about 30% more surface for steep roofs, against 12% for walkable ones.
  • Material and grade. Class 4 shingles cost more than standard architectural ones. Standing-seam metal can run past the top of the published metal range.
  • Old layers. Tearing off two layers of old roofing costs more than tearing off one. Louisville Metro won't let a new layer go over two or more.
  • Deck and rafters. Rotted boards or damaged rafters add work no one can price until the roof is open, and in Metro that structural work needs a building permit.
  • Roof details. Chimneys, skylights, valleys, dormers and walls that meet the roof each need flashing and extra labor.
  • Local steps. A preservation district may need a Certificate of Appropriateness for exterior changes; call (502) 574-6230 before you sign. St. Matthews, Jeffersontown and Shepherdsville expect roofers to hold a city business license.

The calculator leaves out permit costs because a plain re-roof in most of Metro needs none. If your roofer finds deck or rafter damage, expect that line to change and the permit to follow.

What a Written Estimate Includes

A fair comparison needs every quote on the table in the same detail. Before you sign, check that each estimate spells out the following.

  • Layer count and tear-off. How many layers are on the roof today, and the plan to remove them.
  • Measured roof area. The squares or square feet the price is built on.
  • Exact product. Brand, line, grade and color for shingles; panel style and gauge for metal.
  • What goes underneath. Underlayment type and where the ice barrier runs.
  • Flashing, vents and edge trim. Replaced or reused, item by item.
  • Deck repair terms. How damaged boards will be priced if they turn up, and who pulls the permit if structural work is needed.
  • Warranties. The manufacturer's warranty, registered for you, and the roofer's labor warranty, both in writing.
  • Insurance proof. A liability certificate, and workers' comp if the company has employees.
  • Payment schedule and cleanup. When each payment is due, plus disposal and a nail sweep.

If two estimates still differ by thousands, ask each roofer which line explains the gap. Usually it's the layer count, the deck allowance or the product grade.

Your Policy and the Price

When a storm caused the damage, your insurer decides what the policy covers, not the roofer. A roofer can document what's wrong with the roof and write an estimate, and the claim stays between you and your insurance company. Send coverage questions to the insurance company itself, or to the Kentucky Department of Insurance if you want an outside answer.

Two rules affect timing and payment on an insurance-paid job. When the insurer turns down all or part of the claim in writing, you can still cancel the roofing contract up to midnight on the fifth business day after that notice reaches you. The roofer can't require payment in advance until that window has passed, and a cancelled deposit must come back within 10 days. Your contract should include Kentucky's written cancellation notice.

Class 4 impact-resistant shingles cost more, and some insurers price policies lower for them. Call your agent to find out whether yours is one of them before you pick a grade.
