Roofing in Ballwin

Ballwin runs to about 9.1 square miles and roughly 31,279 people. It sits about 18 miles west of downtown St. Louis. There are around 12,563 housing units here, and every one of them has a roof with a clock on it. The community dates back to 1950. We cover ZIP codes 63011 and 63021.

We have not logged a completed roof in Ballwin yet. We would rather say so than put a number on this page that is not real.

The housing stock in Ballwin

The typical home in Ballwin dates to around the mid-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.

Settled in 1837 and incorporated in December 1950, Ballwin's housing stock has a median construction year of 1976; Salem in Ballwin United Methodist Church's original 1870 sanctuary, with a German-language inscription, still stands today.

What we usually find on a late-century roof

Housing from this stretch in Ballwin 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.

The design figures behind the spec

Unlike some states, Missouri does not assign each municipality its own wind and snow numbers — these are metro-wide.

CriterionFigureWhat it drives
Ultimate design wind (Vult)115 mphFastener 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 load20 psfStructure, and how much the eaves hold in a freeze-thaw
Frost depth30 inFootings, not roof covering
Seismic design categoryC residential / D commercialLateral 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.

How Ballwin compares with the rest of St. Louis County

Missouri sets none of this at state level, so a specification that was right one municipality over is not automatically right here.

Common questions about roofing in Ballwin

Do I need a permit to replace a roof in Ballwin?

The city's building permit page lists 'Roofing Requirements' among the items requiring a building permit.

Which building code does Ballwin enforce?

Ballwin enforces the 2015 I-Codes (2024 I-Codes proposed for 2026). The city currently uses 2015 standards and has proposed adopting the 2024 International Codes effective 2026 (2024 IBC, 2024 IRC, 2023 NEC, 2024 IPMC, 2024 IFGC, 2024 IPC, 2024 IMC).

How old are most roofs in Ballwin?

The typical home in Ballwin dates to around the mid-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.

Have you worked in Ballwin before?

Not yet. We have no completed roof logged in Ballwin, and we would rather say so than put a number on this page that is not real.

Does Missouri license roofing contractors?

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 Ballwin 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.
