St. Charles County Roofing

St. Charles roofs, and the specific things this area does to them.

This is not a mild market. NOAA's Storm Events Database logged 54 hail events in St. Charles County between 2020-2025, with stones measured up to 3.0 inches and averaging 1.48 inches. That count is of reported events, not of insured losses, and reporting density tracks population, so a busy county logs more reports than an empty one. Even read conservatively it means a roof in this area takes repeated impact.

What ages a roof here

The Missouri climate is unusually hard on roofing because it swings. Summer decking heat and winter freeze-thaw work the same fasteners in opposite directions across a single year, and the expansion and contraction that comes with it opens the seams around penetrations first. Nail pops, lifted flashing and failed pipe boots show up long before the field of the roof gives out. The result is that most roofs in this area fail at their details rather than their surface.

Permits in St. Charles

Worth knowing before anyone starts: in unincorporated St. Louis County a straight like-for-like asphalt replacement on a slope of 4:12 or steeper does not require a permit. A permit is required below that slope, if more than a quarter of the sheathing is being replaced, or if the roofing material is changing. Municipalities set their own rules on top of the county, and a few of them, Ballwin and Kirkwood among them, run their own contractor licensing rather than deferring to the county. Missouri itself has no state roofing license. Bills to create one were filed in 2016, 2019 and 2021 and all three failed.

What Keys actually does

Three things, and deliberately only three: roofing, gutters and downspouts. No siding, no windows, no general contracting. Shingle work is Atlas and Malarkey.

That last line is the one most roofing companies in St. Louis do not offer at all. A roof that sheds water perfectly into gutters that discharge against the foundation has relocated the problem, not solved it.

Ask about your roof

A real person calls back, usually the same day.

How to judge whoever you call

Four questions separate roofing companies faster than any review score. Are the crews employees or subcontracted day labour, and will the person selling the job ever be on site while it is done? Is there a written scope before a signature, listing what happens if the decking underneath turns out to be soft? What is the warranty on the workmanship as opposed to the manufacturer's warranty on the shingle, and who honours it in four years? And is the company insured for the crew on your roof, not merely licensed?

A company that answers all four plainly is telling you how it operates. One that changes the subject to a discount or a deadline is telling you something as well.

Questions people actually ask

Do I need a permit to replace my roof?

In unincorporated St. Louis County, a like-for-like asphalt replacement on a 4:12 or steeper slope does not need one. Below that slope, or if more than a quarter of the decking is replaced, or the material changes, it does. Municipalities add their own rules.

Is a roofing contractor licensed by the state of Missouri?

There is no state roofing license. Bills to create one were filed in 2016, 2019 and 2021 and all three failed. Licensing is municipal, and it varies house to house across this metro.

How long should a roof last here?

Less than the number on the wrapper, generally. The freeze-thaw cycle and summer decking heat work fasteners in opposite directions across a single year, and most roofs in this area fail at their details rather than their surface.
