What it actually takes to re-roof a house in Waterloo — 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.
Waterloo runs to about 8.18 square miles and roughly 11,013 people. It sits about 24 miles south of downtown St. Louis. There are around 4,666 housing units here, and every one of them has a roof with a clock on it. The community dates back to 1889. We cover ZIP code 62298.
We have not logged a completed roof in Waterloo yet. We would rather say so than put a number on this page that is not real.
The typical home in Waterloo dates to around the mid-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.
Downtown retains a 19th-century core recognized as the Waterloo Historic District (NRHP-listed December 1, 1978), reflecting the town's 1818 founding as a merger of two rival settlements, Bellefontaine and Peterstown.
That includes Bellefontaine and Peterstown. Housing age and construction shift across Waterloo, sometimes by decades within a few streets, which is why we look at the roof before we quote rather than after.
Waterloo formed in 1818 from the unification of two rival communities, Bellefontaine (south) and Peterstown (north); it is the Monroe County seat.
Housing from this stretch in Waterloo 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 city's building permits page lists projects requiring permits — principal buildings, accessory buildings 50+ sq ft, pools, decks, retaining walls over 4 ft — and re-roofing is not among them. That is suggestive of no permit requirement but is not an explicit exemption.
Waterloo enforces the 2006 IRC. The city has adopted the 2012 International Building Code with revisions and the 2006 International Residential Code with revisions, plus the 2012 International Mechanical Code, the National Electric Code, the National Fuel Gas Code and the Illinois State Plumbing Code.
The published number is 618-939-8600. Nathan Krebel is listed as the Zoning Office contact, but the page does not state that he holds the building official title — not recorded as building official. 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 Monroe 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 Waterloo dates to around the mid-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.
It can. Waterloo has Waterloo Historic District. Inside a designated district, changing a visible roof material or colour can need preservation review before the permit is issued. Like-for-like replacement usually raises fewer questions, but we check before quoting.
Not yet. We have no completed roof logged in Waterloo, 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.
