Kansas City, MO · Jackson, Clay, Platte & Cass counties
Kansas City, Missouri roofs: permits and Northland hail.
Census Bureau estimates for 2020–2024 put the median year built for Kansas City, Missouri’s housing at 1969.
The short answer
KCMO says replacing a home’s roofing material, underlayment and no more than 32 square feet of decking needs no permit; replacing more decking does. North of the river, preliminary reports from March 10, 2026 include 3.5-inch hail inside the city near Lake Waukomis.

The city spans four counties, Cass, Clay, Jackson and Platte, on both sides of the Missouri River, and its area plans divide it into three main areas: North of the River, Central and South.
Storm records vary a lot across that much ground, so start with the records at or near your address, then decide whether you want a free inspection from one local roofing partner.
Storm record for Kansas City, Missouri since 2016
Since 2016, National Weather Service storm reports show hail 1 inch or larger within 10 miles of downtown Kansas City, Missouri on 39 days, and wind gusts of 58 mph or more on 69 days, through November 10, 2026.
The largest hail reported in that area was 4.0 in (softball) on March 10, 2026 (a preliminary report).
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 10 miles of downtown Kansas City, Missouri; 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), Kansas City, Missouri is in the middle band. This record uses 10 miles, so its counts differ.
Your own street can differ. Check the storm history for your address or see Kansas City hail history by year.

Before you hire a roofer in Kansas City
- According to Kansas City, Missouri’s City Planning & Development department, replacing the roofing material, underlayment and no more than 32 square feet of decking doesn’t require a permit. Replacing more decking requires a building permit, and the contractor must have a current KCMO business license. MO
- Repairing or replacing rafters or other structural parts requires a scope-of-work review or a formal plan submittal, and a contractor with a KCMO Residential Contractors license in addition to the business license. KCMO also says ice and water shield is required. MO
- KCMO’s list of permit-exempt work covers reroofing one- and two-family homes with a light roof covering, not replacing the roof sheathing or deck or altering the structure. Exempt work must still meet the city’s building code. MO
- Kansas City, Missouri’s Finance Department says construction businesses must be licensed to do business in the city, and that a business license comes before any building permit. MO
- Missouri doesn’t license roofers statewide, so licensing, registration, and permit rules are set by each city. That makes it worth asking a roofer which city requirements apply to your project. MO
