Commercial Roofing
Commercial roofing for St. Charles County and St. Louis buildings
We do commercial roofing as well as residential. If you own or manage a building, start with a conversation about what the roof is, how old it is and what you need from it.

Commercial roofs raise different questions than houses do. Tenants and operations have to keep running, rooftop equipment shares the space, and a flat roof can hide its problems until water shows up inside.
We bring the same approach we use on homes: a free inspection, photos of what we find, a plain explanation and a detailed estimate. Tell us about the building, and we will tell you honestly whether it is work we are the right fit for.

Signs a commercial roof needs attention
Water that lingers after rain
Standing water long after a storm points to drainage that is blocked or not doing its job. FEMA lists interior drains, scuppers, gutters and overflow drains as the parts that move water off a low-slope roof.
Leaks near units or the perimeter
FEMA notes that membrane roofs often fail at the edges in high winds, when metal edge flashing, coping or fascia covers lift and peel.
Blisters, splits or open seams
Surface wear that is worth documenting and fixing before it lets water through.
Storm damage
Wind can tear loose the access panels on rooftop HVAC units, and FEMA warns those panels can become debris that punctures the roof.
No inspection records
If nobody can say when the roof was last inspected, that is your answer.

What building owners should know
A few habits go a long way with a low-slope roof, and none of them require a roofer on retainer.
- Inspect at least twice a year, ideally in spring and fall, and after high winds. That is FEMA’s recommendation for low-slope roofs.
- Keep drains, scuppers and overflow drains clear of leaves and debris.
- Watch the edges and rooftop equipment, where FEMA’s guidance shows wind damage tends to start.
- Keep records of the install date, warranty paperwork and every repair, and get warranty terms in writing.
- Limit roof traffic, and ask trades who service rooftop units to report any damage they cause.
Plan around the people inside
Roofing an occupied building is as much a scheduling job as a roofing job. Tell us early about tenants, deliveries, parking, sensitive equipment and any hours when noise is a problem, so the scope and the estimate reflect how the building actually runs.
Codes and permits
The residential code covers one- and two-family homes and townhouses; other buildings fall under the building code. St. Charles County has adopted the 2021 International Codes with local amendments, and cities set their own adoptions, so confirm the rules with the building department for your address before work starts.
Storm claims on commercial property
Missouri’s roofing claim statute reaches commercial buildings too. Section 407.725 applies to contractors who repair or replace roof systems on residential or commercial real estate, so the same rules hold: no paying or rebating deductibles, and no contractor representing the owner or negotiating the claim. The claim stays yours; we document, meet the adjuster and explain.
Free inspection
We look, photograph what we find and walk you through it. No obligation, no pressure.

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.…
Reassured me and walked me through the process
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
Commercial Roofing: questions
Ask us anything at (314) 222-9529.
Do you work on flat and low-slope roofs?
We do commercial roofing, and the right first step is a conversation about your roof’s system, age and condition. If the job is outside what we do, we will say so.
Can you help with a storm claim on our building?
Yes. We photograph the damage, meet your adjuster at the property to point out what we documented, and go over the scope with you line by line. Decisions on the claim stay with you.
What should we have ready for an inspection?
Roof access details, any drawings or past repair invoices, warranty paperwork and a list of known leaks. The more history we have, the more useful the inspection.
Can you inspect a building before we buy it?
Yes. A documented inspection before closing gives you photos and notes on the roof’s condition to weigh in the deal, and a baseline to compare against later.
Do you also work on our gutters and downspouts?
Yes. Gutters, downspouts and the roof edge are part of the same drainage system, so we look at them together.
