What it actually takes to re-roof a house in Columbia — whether the city wants a permit, which code edition applies, who to call at the building department, and how old the housing here really is. No sales copy dressed up as local knowledge.
Columbia runs to about 10.6 square miles and roughly 11,127 people. It sits about 20 miles south of downtown St. Louis. There are around 4,735 housing units here, and every one of them has a roof with a clock on it. The community dates back to 1859. We cover ZIP code 62236.
We have not logged a completed roof in Columbia yet. We would rather say so than put a number on this page that is not real.
The typical home in Columbia dates to around the early-1990s. A house of that vintage has usually been through two roofs, and the one on it now is often the second — which means it is old enough to be checked rather than assumed.
A relatively young housing stock, with the largest single decade of construction (about 20%) in the 2000s.
First incorporated in 1859 as a small farming settlement on the Mississippi River bluffs, Columbia has grown steadily as suburban development pushes south from St. Louis; sources note Columbia and Waterloo are expected to grow toward each other's borders.
Housing from this stretch in Columbia 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.
Explicit and unambiguous, from the city's own FAQ: no permit is required to replace a roof. However, 'your roofer must be licensed with the State of Illinois.'.
Columbia has not published the edition it currently enforces anywhere we could verify, so this page does not name one. Editions across the metro run from the 2006 IRC to the 2024 IRC, which is a genuinely wide spread — worth asking your contractor which one they are building to.
The published number is 618-281-7144. Columbia 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.
Permitting is on us, not on you.
Unlike some states, Missouri does not assign each municipality its own wind and snow numbers — these are metro-wide.
| Criterion | Figure | What it drives |
|---|---|---|
| Ultimate design wind (Vult) | 115 mph | Fastener schedule and the manufacturer wind rating we specify |
| Nominal design wind (Vasd) | 89 mph (derived, not published locally) | The allowable-stress figure older specs quote |
| Ground snow load | 20 psf | Structure, and how much the eaves hold in a freeze-thaw |
| Frost depth | 30 in | Footings, not roof covering |
| Seismic design category | C residential / D commercial | Lateral bracing and structural connections — not shingles |
What each of these actually does to a roof, why New Madrid does not change how shingles go on, and the difference between the code minimum and the manufacturer minimum on nails per shingle, are all in the St. Louis roofing code guide.
Columbia borders Dupo, Millstadt and Waterloo. These are the ones we also cover, each with its own permit rule and code edition:
Missouri sets none of this at state level, so a specification that was right one municipality over is not automatically right here.
| City | Permit for a re-roof | Adopted code | Building dept. |

| Waterloo | Not published | 2006 IRC | 618-939-8600 |

The typical home in Columbia dates to around the early-1990s, so most roofs here are on their second or third covering rather than their first. That figure is an ACS-derived median republished by housing-data services, not a survey of individual roofs.
Not yet. We have no completed roof logged in Columbia, and we would rather say so than put a number on this page that is not real.
Illinois licenses roofing contractors statewide under 225 ILCS 335, so any roofer working here needs a current IDFPR roofing licence. Missouri, across the river, does not licence roofers at the state level at all.
Permit and code details for Columbia come from the jurisdiction's own published pages and codified ordinances.
