Olathe, KS · Johnson County
Roof inspections in Olathe.
Census Bureau estimates for 2020–2024 put the median year built for Olathe’s housing at 1994, and more than half of its housing units were built in 1990 or later.
The short answer
In Olathe, reroofing a house or townhome down to the deck needs no permit or city inspection, and roofers must hold a Johnson County contractor license and Kansas registration.
Since 2016, National Weather Service reports show hail 1 inch or larger within 5 miles of central Olathe on 23 days and gusts of 58 mph or more on 27 days. The largest hail reported there was 2.0 inches on September 23, 2023.
A free, no-obligation inspection comes from an independent roofing partner that serves Olathe, and checking storm history doesn’t file an insurance claim.
According to the city’s history, Olathe, the Johnson County seat since 1859, counted 37,258 residents in 1981 and reached 100,000 in 2001.
Olathe doesn’t require a permit or city inspection to reroof a house or townhome down to the roof deck (details below). Start with the storms recorded at or near your address, then decide whether you want a free inspection from one local roofing partner.
Storm record for Olathe since 2016
NOAA/NWS storm reports through November 10, 2026.
These are records for the wider area, not for your address. A storm on record doesn’t mean your roof was damaged, and it doesn’t mean your insurance company will accept that storm or date. That’s why an inspection is worth having: a roofing professional looks at the roof itself.

How we count. A hail day is a day with at least one National Weather Service hail report of 1 inch or larger within 5 miles of central Olathe; a wind day has a measured or estimated gust of 58 mph or more. Data through November 10, 2026.
The full method and source
Several reports on the same day count once.
Our storm records come from NOAA radar estimates and National Weather Service reports. Radar can miss or misjudge hail, and a report marks a single spot, so records can be incomplete. Treat them as a starting point, not a verdict about your roof.
Radar hail days use NOAA’s radar estimates (MRMS) of 1 inch or larger over the same area, counted only when the Weather Service also logged hail within 15 miles that day. 2026 numbers come from preliminary reports and can change.
Source: NOAA / National Weather Service Storm Prediction Center storm reports and NOAA MRMS radar hail estimates, retrieved November 11, 2026. Data through November 10, 2026; 2026 reports are preliminary and can still change. Compiled by Roof Inspectors from public-domain NOAA data. How storm data works.
On our hail-by-place comparison (5-mile circles, 2016–2025), Olathe is in the higher band.

Before you hire a roofer in Olathe
- According to the City of Olathe, permits aren’t required for reroofing or repairs down to the roof deck on one- and two-family homes and townhomes, and city inspections aren’t required. The work must still meet the currently adopted International Residential Code and the Olathe Municipal Code. KS
- Olathe’s summary of common reroofing requirements includes an ice barrier from the lowest roof edges to at least 24 inches inside the exterior wall line, a drip edge at eaves and rakes, and replacing flashings that are rusted, damaged or deteriorated. KS
- Olathe also notes that roofing contractors must hold a valid Johnson County contractor license and be registered with the State of Kansas. Since no permit or city inspection is involved, checking your roofer’s credentials matters even more. KS
- Johnson County’s contractor licensing office lists a Class DR license for roofing-only work. Its Class A, B and C licenses also cover roofing; Class C is limited to single-family and two-family homes. KS
- Kansas requires roofing contractors to register with the Kansas Attorney General before doing residential or commercial roofing work for pay. Ask any roofer for their registration number — and look it up. KS
