Roofing for Edwardsville homes: replacement, leaks and storm damage. In Edwardsville, the 2021 IRC is in force and 73% of the 10,609 homes were built before 2000. Any permit the job needs is ours to pull.
Edwardsville runs to about 20.0 square miles and roughly 26,474 people. It sits about 18 miles northeast of downtown St. Louis. The community dates back to 1818. We cover ZIP codes 62025 and 62026.
No completed roof in Edwardsville is logged in our job records yet.
Edwardsville built out steadily over the later 20th century, with only modest growth (about 3%) since 2020.
That includes Leclaire. Housing age and construction shift across Edwardsville, sometimes by decades within a few streets, which is why we look at the roof before we quote rather than after.
Edwardsville was incorporated in 1818. Its Leclaire Historic District was a planned 19th-century industrial cooperative village, annexed into the city in 1934, and Historic Saint Louis Street has more than 50 homes dating from the mid-19th to early-20th century. During the December 10-11, 2021 tornado outbreak, an EF3 tornado collapsed an Amazon warehouse in Edwardsville, killing six workers.
Housing from this stretch in Edwardsville sits on plywood or OSB decking and was largely first roofed with three-tab shingles. Most are on their second covering by now. The things worth checking are the penetrations rather than the field: pipe boots from this era are the single most common leak we trace, because the rubber collar splits long before the shingles wear out. Ridge venting was inconsistent through these years, and OSB that has been damp for a season goes soft in a way plywood does not — you find it with your feet, not from the ground.
By the Census Bureau's estimate there are 10,609 homes in Edwardsville, with a median year built of 1986. 1,665 of them (16%) went up before 1940 — 13th of 48 places on this site for pre-1940 share — and 2,835 (27%) in 2000 or later. The 1990s were the busiest decade, adding 1,945 of today's homes (18%). That is above Madison County's 15%.
The rule of thumb from Missouri's Department of Commerce and Insurance is a useful life of usually about 25 years for a roof. By that measure, 73% of Edwardsville's homes — the 7,774 built before 2000 — are past their first roof, and the 3,764 built before 1970 (35%) are usually on a third covering or later. First replacements are arriving on the 1,327 homes built in the 2000s, while the 1,508 built since 2010 are mostly still on the roof they were built with. On houses that old, the question worth asking is how many layers are up there: a roof laid over an old one hides the deck.
71% of homes in Edwardsville are single-family detached houses (7,510) and 3% attached ones such as townhouses (314). 1,122 homes (11%) sit in two- to nine-unit buildings and 1,663 (16%) in buildings of ten units or more, whose roofs are normally an owner's or a board's call rather than a resident's. 6,547 of 9,828 occupied homes (67%) are lived in by their owners. On a housing mix like this, the likely work is deck and flashing checks on pre-war board sheathing and first replacements on 2000s builder-grade shingles.

Between 2016 and 2025 there were 8 reports of 1-inch-plus hail within 5 miles of Edwardsville’s center in the records of NOAA’s Storm Prediction Center, on 5 separate days. 2 of them were 1.75 inches or larger. The largest, 1.75 inches, came on March 14, 2025, about 4.5 miles south of the center. The most recent was 1 inch on May 16, 2025. 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 16, 2025 | 1 inch | 2.2 mi S |
| March 14, 2025 | 1 inch | 3.5 mi SE |
| March 14, 2025 | 1 inch | 3 mi SE |
| March 14, 2025 | 1 inch | 2.1 mi SE |
| March 14, 2025 | 1.75 inches | 4.5 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.
Nothing Edwardsville publishes says whether a like-for-like re-roof needs a permit. We call the department before the job and pull whatever is required.
Edwardsville enforces the 2021 IRC. The city has adopted the 2021 International Building Code and 2021 International Residential Code, with amendments, per its Building Measures & Adopted Codes page.
We could not find a published number for the building department, so this page does not print one. Edwardsville does not publish the building official's name, so this page does not name one. Plenty of sites will show you one anyway. The department page is here.
Wind 115 mph (ultimate) and ground snow 20 psf, the same across the metro; see the roofing code guide for what they govern.

Older than most people guess: the Census puts 73% of Edwardsville's homes before 2000 and 35% before 1970, with a median year built of 1986 (2020–2024 estimates). A roof usually lasts about 25 years, so the deck and the layers get checked before any quote.
Yes. The most recent report of hail 1 inch or larger within 5 miles of Edwardsville's center was 1 inch on May 16, 2025, one of 8 such reports from 2016 through 2025.
It can. Edwardsville has Leclaire Historic District and Saint Louis Street Historic District. Inside a designated district, changing a visible roof material or color can need preservation review before the permit is issued. Like-for-like replacement usually raises fewer questions, but we check before quoting.
Not yet: no completed roof in Edwardsville is in our job records, so this page shows no job count.
