Roofing for Chesterfield homes: replacement, leaks and storm damage. In Chesterfield, the 2015 IBC / 2015 IRC are in force and the median home was built in 1982. Any permit the job needs is ours to pull.
Chesterfield runs to about 31.8 square miles and roughly 49,574 people. It sits about 25 miles west of downtown St. Louis. The community dates back to 1988. We cover ZIP codes 63005 and 63017.
No completed roof in Chesterfield is logged in our job records yet.
Chesterfield's homes were mostly built from the 1970s through the 1980s (about 32% in the 1970s, 23% in the 1980s).
We work across Chesterfield rather than one corner of it — Bellefontaine, Lake, Gumbo, Monarch and Bonhomme included. Age and construction change between them, which is why we look before we quote.
Chesterfield incorporated in 1988 out of several older communities, and it includes the Missouri River floodplain once known as Gumbo Flats, now Chesterfield Valley. A violent F4 tornado cut a 21-mile path across St. Louis County on January 24, 1967. On July 30, 1993, the Gumbo Flats levee failed for the first time since 1935, flooding the valley. Both are major storm events in the city's history.
From this stretch of building, houses in Chesterfield sit on plywood or OSB, were first roofed in three-tab shingles, and are mostly on their second roof now. Trouble tends to be at the penetrations rather than across the field: the rubber collar on a pipe boot splits years before the shingles give out, and it is the leak we trace most often. Ridge vents were hit and miss in these decades, and OSB that stays damp for a season softens in a way plywood does not, something you feel underfoot rather than see from the yard.
By the Census Bureau's estimate there are 21,603 homes in Chesterfield, with a median year built of 1982. 302 of them (1%) went up before 1940 — 36th of 48 places on this site for pre-1940 share — and 3,569 (17%) in 2000 or later. The 1970s were the busiest decade, adding 6,895 of today's homes (32%). That is below St. Louis County's 10%.
Missouri's Department of Commerce and Insurance puts the useful life of a roof at usually about 25 years. On that yardstick the 18,034 homes in Chesterfield built before 2000 (83%) have outlived at least one roof, and 14% (3,105 homes) go back before 1970, two roof lives and more. Homes from the 2000s (2,184 in Chesterfield) are reaching their first replacement, while the 1,385 built since 2010 are mostly still on the roof they were built with.
63% of homes in Chesterfield are single-family detached houses (13,510) and 12% attached ones such as townhouses (2,631). 1,960 homes (9%) sit in two- to nine-unit buildings and 3,376 (16%) in buildings of ten units or more, where the roof is usually a landlord's or an association's decision. The count also takes in 126 mobile homes, which are a different kind of roof job. 16,143 of 20,811 occupied homes (78%) are lived in by their owners. Read together, those figures point toward flat and low-slope sections, which turn up more on attached and multi-unit buildings.

Between 2016 and 2025 there were 17 reports of 1-inch-plus hail within 5 miles of Chesterfield’s center in the records of NOAA’s Storm Prediction Center, on 6 separate days. 7 of them were 1.75 inches or larger. The largest, 2 inches, came on May 16, 2025, about 0.9 miles east of the center. Counts follow people as much as storms, since every report is a spotter’s or a resident’s.
| Latest reports | Size | From center |
|---|---|---|
| May 16, 2025 | 1.25 inches | 1.4 mi E |
| May 16, 2025 | 1.5 inches | 1.2 mi NE |
| May 16, 2025 | 1 inch | 2.9 mi NE |
| May 16, 2025 | 1 inch | 1.4 mi E |

A bruised shingle can look fine for a season or two, which is why a storm inspection after a date like these is worth having.

Nothing Chesterfield publishes says whether a like-for-like re-roof needs a permit. We call the department (636-537-4000) before the job and pull whatever is required.
Chesterfield enforces the 2015 IBC / 2015 IRC. City Code Section 500.001 adopts the 2015 International Building Code, and Section 500.002 adopts the 2015 International Residential Code for One and Two Family Dwellings. Both have local amendment schedules attached (500a and 500b).

The design figures are metro-wide rather than local: 115 mph ultimate design wind and a 20 psf ground snow load. What they do to a roof is in the roofing code guide.
