Roof replacement, leak repair and hail & storm damage for homes in Brentwood. In Brentwood, the 2024 IRC is in force and the median home was built in 1956. It starts with a free inspection that photographs every slope.
Brentwood runs to about 2.0 square miles and roughly 8,144 people. It sits about 8 miles southwest of downtown St. Louis. The community dates back to 1919. We cover ZIP code 63144.

Brentwood's housing was predominantly built during the 1950s postwar boom (about 36% of homes).
Originally called Maddenville, Brentwood incorporated as a village in 1919, largely to avoid annexation by Maplewood, and became a city in 1929. It is one of the most densely populated inner-ring suburbs in St. Louis County, and its median home was built in 1956.
Postwar houses in Brentwood are plain to roof, which is exactly why so many get roofed carelessly. Expect 1x6 board decking or early plywood: usually sound, but it should be walked, not assumed. The weak spots are the shallow pitches — a porch roof, the join to a carport, the flat section over an addition — where shingles went on below their rated slope and have leaked slowly for years. Attics from this era rarely have the ventilation today's shingle warranties ask for, and a hot, under-vented attic ages a roof from below, so intake and exhaust get measured before the quote.
Brentwood has 4,442 homes in the Census Bureau's count and a median year built of 1956. 637 of them (14%) went up before 1940 — 14th of 48 places on this site for pre-1940 share — and 585 (13%) in 2000 or later. The 1950s were the busiest decade, adding 1,612 of today's homes (36%). Across St. Louis County the pre-1940 share is 10%, so Brentwood sits above it.
The rule of thumb from Missouri's Department of Commerce and Insurance is a useful life of usually about 25 years for a roof. That puts 3,857 homes in Brentwood, the 87% built before 2000, past at least one full roof life, and the 3,273 built before 1970 (74%) are usually on a third covering or later. First replacements are arriving on the 327 homes built in the 2000s, while the 258 built since 2010 are mostly still on the roof they were built with. Older houses are where a second layer laid over the first turns up, and that layer is what hides soft decking.
By building type: 2,188 detached houses (49%), 457 attached (10%). 1,250 homes (28%) sit in two- to nine-unit buildings and 461 (10%) in buildings of ten units or more, where a resident rarely gets to choose the roofer. The count also takes in 86 mobile homes, which are a different kind of roof job. 63% of occupied homes are owner-occupied, 37% rented. Read together, those figures point toward full tear-offs on houses past two roof lives and flat and low-slope sections, which turn up more on attached and multi-unit buildings.

From 2016 through 2025, NOAA’s Storm Prediction Center recorded 38 reports of hail of 1 inch or more within 5 miles of Brentwood’s center, spread over 16 storm days. 7 of them were 1.75 inches or larger. The largest, 2 inches, came on May 19, 2025, about 0.9 miles southwest of the center. A report needs someone to see the hail and send it in, so the count is a floor, not a full tally.
| Latest reports | Size | From center |
|---|---|---|
| May 19, 2025 | 1.25 inches | 1.5 mi SW |
| May 19, 2025 | 1.75 inches | 4.8 mi SW |
| May 19, 2025 | 1 inch | 4.5 mi W |
| May 19, 2025 | 2 inches | 0.9 mi SW |
| May 16, 2025 | 1.5 inches | 2.3 mi NE |
Hail damage rarely shows from the ground; a storm inspection photographs each slope so you know either way.
The city's Building & Occupancy Permits page says 'Exterior alterations to homes, except for decks, window replacements, fences and roof shingles, must be reviewed...' That exception covers the city's architectural (design) review, not necessarily the permit itself. We confirm the re-roof permit requirement with the city before work starts.
