Wentzville was Missouri's fastest-growing city by percentage from 2000 to 2020, growing from 7,058 to 44,372 residents, so the large majority of its housing is 21st-century new construction.
That includes Bear Creek. Housing age and construction shift across Wentzville, sometimes by decades within a few streets, which is why we look at the roof before we quote rather than after.
Wentzville has a 'Historic Downtown Wentzville' commercial area, the subject of a Missouri State Parks reconnaissance survey. The Wentzville Tobacco Company Factory there is individually listed on the National Register.
Newer construction in Wentzville generally has OSB decking, architectural shingles and a proper ridge vent, so the roofs themselves start in better shape. The catch is what the shingle was: a great deal of the building through the 2000s went on with builder-grade shingles carrying a nominal warranty far longer than their real service life, and those are reaching the end now. Hail is the other factor — a newer roof is not a hail-proof roof, and a bruised mat can look perfect from the driveway for two years and then start failing all at once. If yours has never been looked at after a storm, that is the reason to have it looked at.
Wentzville has 16,601 homes in the Census Bureau's count and a median year built of 2008. 104 of them (1%) went up before 1940 — 43rd of 48 places on this site for pre-1940 share — and 13,486 (81%) in 2000 or later. The 2000s were the busiest decade, adding 6,855 of today's homes (41%). (St. Charles County as a whole: 2% before 1940.)
Missouri's Department of Commerce and Insurance puts the useful life of a roof at usually about 25 years. By that measure, 19% of Wentzville's homes — the 3,115 built before 2000 — are past their first roof, and 8% (1,286 homes) go back before 1970, two roof lives and more. First replacements are arriving on the 6,855 homes built in the 2000s, while the 6,631 built since 2010 are mostly still on the roof they were built with.
Detached single-family houses make up 82% (13,664); attached houses and townhouses 7% (1,185). 530 homes (3%) sit in two- to nine-unit buildings and 1,186 (7%) in buildings of ten units or more, whose roofs are normally an owner's or a board's call rather than a resident's. Owners live in 82% of the 16,294 occupied homes. With houses like these, the jobs we expect most are first replacements on 2000s builder-grade shingles and hail checks on newer roofs that look fine from the driveway.

From 2016 through 2025, NOAA’s Storm Prediction Center recorded 11 reports of hail of 1 inch or more within 5 miles of Wentzville’s center, spread over 10 storm days. 2 of them were 1.75 inches or larger. The largest, 3 inches, came on March 14, 2024, about 4.3 miles west of the center. The most recent was 1.25 inches on April 16, 2024. These are reports, not a full record: they come from spotters and the public, so busier areas log more.
| Latest reports | Size | From center |
|---|---|---|
| April 16, 2024 | 1.25 inches | 3.4 mi NW |
| April 1, 2024 | 1 inch | 1.1 mi S |

If one of those storms crossed your street and nobody has been on the roof since, a storm inspection photographs what it did.

Median year built 2008, by the Census Bureau's 2020–2024 estimates. Of 16,601 homes, 3,115 were built before 2000 and 104 before 1940, so most roofs in Wentzville are not the first one the house has had.
11 reports of 1-inch-plus hail fell within 5 miles of Wentzville between 2016 and 2025, the biggest 3 inches on March 14, 2024 (NOAA Storm Prediction Center).
