No completed roof in Glen Carbon is logged in our job records yet.
That includes Old Town. Housing age and construction shift across Glen Carbon, sometimes by decades within a few streets, which is why we look at the roof before we quote rather than after.
Glen Carbon's heritage museum grounds include the Yanda Log Cabin, built around 1853 and one of the area's oldest structures. The village itself was founded in 1892.
Housing from this stretch in Glen Carbon 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 6,007 homes in Glen Carbon, with a median year built of 1990. 310 of them (5%) went up before 1940 — 25th of 48 places on this site for pre-1940 share — and 1,587 (26%) in 2000 or later. The 1990s were the busiest decade, adding 1,411 of today's homes (23%). (Madison County as a whole: 15% before 1940.)
Missouri's Department of Commerce and Insurance puts the useful life of a roof at usually about 25 years. That puts 4,420 homes in Glen Carbon, the 74% built before 2000, past at least one full roof life; 969 of them (16%) predate 1970, old enough for two replacements already. First replacements are arriving on the 950 homes built in the 2000s, while the 637 built since 2010 are mostly still on the roof they were built with.
Detached single-family houses make up 70% (4,175); attached houses and townhouses 7% (393). 936 homes (16%) sit in two- to nine-unit buildings and 457 (8%) in buildings of ten units or more, whose roofs are normally an owner's or a board's call rather than a resident's. 69% of occupied homes are owner-occupied, 31% rented. Read together, those figures point toward first replacements on 2000s builder-grade shingles and flat and low-slope sections, which turn up more on attached and multi-unit buildings.

NOAA’s Storm Prediction Center logged 9 reports of hail 1 inch or larger within 5 miles of Glen Carbon’s center from 2016 through 2025, on 6 different days. 3 of them were 1.75 inches or larger. The largest, 1.75 inches, came on March 14, 2025, about 2.3 miles southeast of the center. The most recent was 1 inch on May 16, 2025. Counts follow people as much as storms, since every report is a spotter’s or a resident’s.

Hail damage rarely shows from the ground; a storm inspection photographs each slope so you know either way.
Nothing Glen Carbon publishes says whether a like-for-like re-roof needs a permit. We call the department (618-288-2603) before the job and pull whatever is required.
Glen Carbon does not publish the code edition it currently enforces, so this page does not name one. Editions across the metro run from the 2006 IRC to the 2024 IRC — worth asking any contractor which one they are building to.
The published number is 618-288-2603. The building official on record is Kari Crawford, Building Official (618-288-2674). The department page is here.
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.
