A Kentucky roof defect claim does not stay open forever. KRS 413.135 sets an outer limit of seven years after substantial completion for any action arising out of a deficiency in the construction of an improvement to real property — with one narrow extension, and a definition of “substantial completion” that surprises people when the work was a re-roof rather than a new house.
How long do you have to sue over a defective roof in Kentucky?
Seven years from substantial completion is the outer limit. The statute bars construction-deficiency actions brought after that period, whether the claim sounds in contract or in tort.
KRS 413.135(1): “No action to recover damages, whether based upon contract or sounding in tort, resulting from or arising out of any deficiency in the construction components, design, planning, supervision, inspection, or construction of any improvement to real property, or for any injury to property, either real or personal, arising out of such deficiency…shall be brought against any person after the expiration of seven (7) years following the substantial completion of such improvement.”
Read the list of covered activities closely. It is not only “construction” — it names design, planning, supervision and inspection as well. That breadth is why the section comes up in disputes about who looked at a roof, not just who installed it.
When does the seven years actually start?
At occupancy or first use. The statute defines substantial completion as the date the owner “first entered upon the occupancy or commenced the use” of the structure — not the date the crew finished.
Subsection (4) provides that “the term ‘substantial completion’ shall be construed to mean the date upon which the owner of the structure, project, or facility first entered upon the occupancy or commenced the use thereof.”
That definition was plainly written with new construction in mind, and it is awkward on a re-roof of a house the owner has lived in for twenty years — occupancy began long before the roof did. How a Kentucky court applies it to replacement work on an occupied building is a legal question, and it is exactly the kind of question that gets argued rather than assumed. If a date matters to your situation, that is an attorney’s call on your specific facts, not something to settle from a web page.
The statute measures from the day the building was first used — not from the day the leak appeared, and not from the day anyone noticed why.
What if the damage shows up in year seven?
There is a one-year extension, capped hard. An injury occurring during the seventh year can be sued on within one year of the injury — but never more than eight years after substantial completion.
Subsection (2): “in the case of such an injury to property or the person or wrongful death resulting from such injury, which injury occurred during the seventh year following substantial completion of such improvement, an action to recover damages for such injury or wrongful death may only be brought within one (1) year from the date upon which such injury occurred (irrespective of the date of death), but in no event may such an action be brought more than eight (8) years after the substantial completion of construction of such improvement.”
Note what subsection (3) adds: “Nothing in this section shall be construed as extending the period prescribed by statute for the bringing of any action for damages.” In other words this section is a ceiling, not a floor. The ordinary limitation period for your type of claim still applies inside it, and it may be much shorter than seven years. Two clocks, and the earlier one wins.
Why does the statute say seven years in one place and eight in another?
Because the period was lengthened from five years to seven in 1986 and the second subsection was not updated to match, so the Reviser of Statutes made a technical correction.
The Legislative Research Commission note published with the section records it: “Subsection (1) of this section was amended in 1986 Acts Ch. 479, Section 1, to extend the period of time in which certain actions may be brought from five to seven years. Inadvertently, when the period of time was extended by committee amendment, subsection (2) was not amended to conform. Pursuant to KRS 7.136, the Reviser of Statutes has made a technical correction in order to make the subsections consistent.”
It is a small thing, but it is the reason older summaries of this statute circulating online still say five years. Read the current text, which the Legislative Research Commission publishes and dates.
What this means for a homeowner, practically
Documentation is the whole game, because every deadline in this area runs from a date someone has to prove. Keep the contract, the invoice, the dated photographs, and the manufacturer paperwork for the shingles or membrane that went on. If a roof is three years old and something is wrong, that is a conversation worth having now rather than in year six — not because of litigation, but because a problem caught early is usually a repair instead of a replacement. Our own workmanship commitment is written out on our workmanship warranty page, and it is a separate thing from any statutory period.

Frequently asked questions
Does this statute apply to a repair, or only a whole new roof?
The section speaks to a “deficiency in the construction components, design, planning, supervision, inspection, or construction of any improvement to real property.” Whether a particular repair is an “improvement to real property” for this purpose is a legal question that turns on the facts. The statute does not list roof work specifically either way.
Who does “any person” cover?
Subsection (4) defines “person” for this section as “an individual, corporation, partnership, business trust, unincorporated association, or joint stock company.” That is broader than the installing contractor alone.
Is seven years the same as a warranty?
No, and conflating them is the most common mistake here. A statute of repose is an outer limit on bringing a legal action. A warranty is a contract promise with its own term and its own conditions. One does not extend or shorten the other.
