What it actually takes to re-roof a house in Mehlville — whether the county 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.
Mehlville runs to about 7.63 square miles and roughly 28,955 people. It sits about 12 miles south of downtown St. Louis. There are around 13,854 housing units here, and every one of them has a roof with a clock on it. We cover ZIP codes 63125, 63128 and 63129.
We have not logged a completed roof in Mehlville yet. We would rather say so than put a number on this page that is not real.
The typical home in Mehlville dates to around the late-1970s. 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.
, consistent with Mehlville's description in census data as a fully urbanized, inner-ring St. Louis County suburb.
Mehlville is an unincorporated census-designated place -- never a city -- and is 100% urban per census data, encompassing areas also associated with the Lemay, Tesson Ferry, and Oakville townships.
Housing from this stretch in Mehlville 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.
Building permits and inspections are handled by St. Louis County Public Works.
Mehlville 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 314-615-5184. Mehlville 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.
Elsewhere in St. Louis County we also cover:
Missouri sets none of this at state level, so a specification that was right one municipality over is not automatically right here.

The typical home in Mehlville dates to around the late-1970s, 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 Mehlville, and we would rather say so than put a number on this page that is not real.
Missouri has no state-level roofing contractor licence. Licensing and registration are imposed municipally, and several St. Louis metro cities require it. Illinois does licence roofers statewide, so a contractor working the Metro East needs an IDFPR roofing licence.
Permit and code details for Mehlville come from the jurisdiction's own published pages and codified ordinances. Population, housing and neighbourhood detail come from census data and the sources below; housing-age figures are ACS-derived medians republished by housing-data services, so treat them as approximate.
