Imperial, Jefferson County
Imperial roofs, gutters and storm repair
Imperial has no city government, so Jefferson County sets the building rules. Its houses range from prewar homes to ones built this decade, and its hail record is short but recent.

Imperial, once known as West Kimmswick, runs from Arnold’s southern edge down to Barnhart, with the Mississippi on its east side and I-55 running through it. It is home to Mastodon State Historic Site, where researchers established that people and the American mastodon lived at the same time in eastern North America.
Because Imperial is unincorporated, there is no city hall to call about a roof. Jefferson County Code Enforcement in Hillsboro covers the whole area, and under the county’s residential code, replacing the roof on a single-family house does not need a permit. That puts more weight on choosing a careful roofer.

Local homes
Prewar houses, 1980s subdivisions and new builds
Imperial’s housing came in waves, by Census estimates: 19.7% of homes from the 1980s, 15.4% from the 1990s, 19.8% from the 2000s and 9.7% built in 2020 or later, with about one in eight going back to the 1950s or earlier. Owner occupancy runs high, at 93%.
That spread means a 40-year-old roof can sit across the street from one still covered by its first manufacturer warranty. On newer houses, keep the paperwork: manufacturer warranties come with the materials, registration and installation rules apply, and the terms are worth getting in writing. On older houses, look at the gutters, fascia and soffit as closely as the shingles.
Hail and wind
A short hail record, mostly from one night
Only eight hail reports within 5 miles of Imperial appear in NOAA’s database since 2015, spread over just two days, and seven of them belong to March 14, 2025, when 1.75-inch hail was reported near Imperial. The National Weather Service counts that night among the busiest tornado outbreaks in its St. Louis office’s records, and Jefferson County accounted for 23 of the 83 hail reports NOAA lists across the region.
A thin record is not a clean bill of health. The database depends on people seeing and reporting hail, so it undercounts rural areas and storms after dark, and a roof can take damage that never makes the list.
Source: NOAA National Centers for Environmental Information, Storm Events Database, hail reports with a location within 5 miles of the center of Imperial, January 2015 to June 2026. Reports come from spotters, NWS staff and the public, so they undercount.
Services
What we do in Imperial
Roof Replacement
Imperial jobs run from a full tear-off on a 1960s house to the first re-roof on a 2000s build. The old shingles are recycled, and every job ends with a final inspection and photos.
Learn moreStorm and Hail Damage Repair
If the March 2025 hail reached your roof, we photograph the damage, show it to you photo by photo, and help you open a claim if the damage is worth it.
Learn moreFree Roof Inspections
With no county permit or inspector involved in a typical single-family re-roof here, your own inspection carries more weight. Ours is free, photographed, and walked through with you.
Learn moreEmergency Roof Repair
When a storm leaves a roof open to the weather, call us. We respond to storm damage and other urgent roof problems, then plan the permanent repair.
Learn moreGutters and Downspouts
We install seamless, custom-fit gutters, re-hang sagging runs and set downspouts so water leaves the foundation instead of pooling beside it.
Learn moreImperial is unincorporated, so building matters go to the Jefferson County Code Enforcement Division in Hillsboro, which regulates construction in all of unincorporated Jefferson County. As of 2026, the county’s amendments to the residential code (Section 500.400) list single-family roof replacement, including shingles, underlayment and sheathing, among work that does not need a building permit, and siding replacement is on the same list.
The code adds that an exemption is not permission to break the code, so the roof still has to be built to it. The county can revise its rules, so call Code Enforcement (636-797-5310) to confirm before work begins.
Fixed on the spot
I had a leak in my roof and called a couple different roofing companies to check it out. None of them could figure out where it was coming from, they just told me I’d need a whole new roof. Then I called Correll Roofing Company. Curtis came out…
Knowledgeable, polite, and responsive
I contacted Correll Roofing about some shingles that I lost off of my roof during this last round of high winds that we experienced. Jon responded to my inquiry quickly, came out to my home and replaced the missing shingles in a very timely manner.…

I had the pleasure of working with Devin Stinson and am currently getting my roof replaced. I had waited almost too long to do it as I am a first time homeowner. The process was a little scary but Devin reassured me and walked me through the process…
FAQ
Roofing in Imperial: questions
Call (314) 222-9529 if yours is not here.
Do I need a permit to replace my roof in Imperial?
Under Jefferson County’s current residential code amendments, a single-family roof replacement is listed among the work that does not need a building permit. The work still has to meet code, and the county can change its rules, so check with Code Enforcement before you start.
Who answers building questions in Imperial?
For homes in unincorporated Imperial, Jefferson County Code Enforcement at 725 Maple Street in Hillsboro handles building permits, inspections and code questions. There is no City of Imperial to call.
Imperial only has eight hail reports on record. Should I worry about hail?
Worry is the wrong word, but check. Seven of those reports came on one evening, March 14, 2025, with stones up to 1.75 inches, and the database misses hail that nobody reports. A free inspection with photos will tell you whether that night left a mark.
If no permit is needed, how do I know my new roof was done right?
Ask for photos of the bare deck, the underlayment and the flashing before shingles cover them, and keep them with your house records. The county code still applies to the work even without a permit, so it is fair to ask any roofer how they meet it. Our jobs finish with a final inspection and photos.
