Roof Replacement in Louisville, KY

When replacement tends to come up

Repairs make sense when the damage is limited. Replacement becomes the more practical conversation when leaks keep coming back in different spots, when a storm has damaged a large portion of the roof, or when a roofer finds that the decking underneath has been compromised by water over time.

Louisville Metro's rules also play a role. A new layer of roofing cannot go over material that is water-soaked or badly damaged, or over slate, clay, cement, or asbestos-cement tile. It also cannot go over a roof that already has two or more layers. If your roof is already at two layers, the next job has to be a full tear-off, which is also a natural point to evaluate the whole system.

Louisville Metro's rules for a roof replacement

Louisville Metro says a full roof replacement means removing all the old layers down to the roof deck. Rusted or damaged old flashing must be replaced at the same time.

On permits: Louisville Metro says a straight reroof generally does not need a building permit, but structural repairs like replacing the roof deck or rafters do. Ask your roofer whether your specific job needs one.

Louisville Metro adopts the 2015 International Residential Code with Kentucky amendments. Under that code, shingle roofs require a metal drip edge along the eaves and gables (Louisville Metro roofing guide).

If you are in St. Matthews, the city has to issue a free Letter of Compliance before Louisville Metro will issue a building permit, and contractors need a St. Matthews business license.

Material options worth asking about

A roofer can walk you through what makes sense for your home. A few things are worth knowing before that conversation.

On impact-rated shingles: UL 2218 rates roof coverings Class 1 to 4 by dropping steel balls, with Class 4 being the top rating and using a 2-inch ball. IBHS lab tests found that shingles labeled impact-resistant did not all perform the same, and IBHS suggests choosing shingles rated Good or Excellent in its own shingle ratings.

Metal roofing is another option. Louisville Metro allows a complete standing-seam metal roof as a separate system, even over an existing roof, because it carries its own weight.

Ask your roofer about the IBHS FORTIFIED Roof standard. The FORTIFIED designation calls for things like ring-shank nails and a sealed roof deck, and its hail designation calls for shingles rated for hail up to 2 inches. Since March 1, 2026, Kentucky homeowners insurers must offer an optional endorsement that pays to upgrade a covered roof replacement to the FORTIFIED Roof standard. Kentucky law also requires insurers to give a premium discount for FORTIFIED-certified homes when the discount is actuarially justified. Ask your insurer what it offers. A FORTIFIED designation lasts five years and transfers when you sell the house (Kentucky Department of Insurance).

If insurance is involved

A few Kentucky rules apply when a roof replacement is being paid by insurance.

Kentucky law bars contractors from offering to pay or rebate any part of your insurance deductible, from giving a discount against the fee, and from giving you anything worth more than $100 on an insurance-paid job (KRS 367.628). On those jobs a contractor also cannot require advance payment until the cancellation period runs out.

If your insurer tells you in writing that any part of the job is not covered, you can cancel the contract until midnight of the fifth business day after that notice (KRS 367.622).

Since 2024, Kentucky law says you cannot sign your insurance policy rights or benefits over to someone else. Paying a contractor directly for covered work is still allowed (KRS 304.20-105).

The Kentucky Department of Insurance notes that the first insurance check is often an advance, not the final payment, and that you may have to bring your home up to current building codes when you repair. Ask your agent whether your policy pays for that.

Your policy decides what is covered. Call your insurance agent with questions about your claim.

What affects the cost of a replacement

A roofer will price the job based on what they find. Factors that tend to matter include the size and pitch of the roof, how many layers need to come off, the condition of the decking underneath, the materials chosen, and whether any structural repairs are needed. A new roof is a significant job, so getting more than one written estimate is worth the time.

How to choose a roofer for a replacement

IBHS suggests getting at least three written estimates. Ask any roofer for proof of general liability insurance and, if they have employees, workers' compensation coverage. The Kentucky Attorney General recommends not paying a contractor up front and getting a written contract that covers the scope of work, the general time frame, and the cost. IBHS also suggests looking for a roofer with a permanent local presence and experience with your roof type, and making sure the roofer pulls any permits the local rules require.

Kentucky does not license roofers at the state level, so checking insurance and getting everything in writing matters.
