St. Louis has one of the oldest housing stocks of any major American city, built largely in brick with flat or low-slope roofs behind parapet walls. That geometry — not the weather — determines how these roofs fail, and it is why a contractor experienced in the local stock is worth more here than a general shingle crew. This page lists roofers serving St. Louis.
What St. Louis roofers handle
Flat and low-slope membrane roofing, the dominant system on the older stock.
Parapet and coping repair, where these roofs actually leak.
Coating and re-coating, the maintenance cycle for flat roofs.
Full replacement on asphalt shingle in the newer neighbourhoods.
Roof deck replacement on century-old framing.
Historic district work in the protected neighbourhoods.
Licensing in Missouri
Missouri issues no statewide contractor licence. Roofing is regulated municipally, and the two largest cities do it differently:
- Kansas City requires a Residential Building Contractor Licence. The applicant must be at least 21, hold a high school diploma or GED, and pass the International Code Council (ICC) Residential Building Contractor exam. The licence costs $55 and runs four years.
- St. Louis requires a Construction Industry Contractor Graduated Business Licence for all contractors.
Kansas City’s exam requirement is the more substantial of the two — it is an actual test of code knowledge rather than a registration form.
Because there is no state standard, verify general liability and workers’ compensation yourself, and confirm the licence matches the municipality your house is in.
What’s specific to St. Louis
Parapets and coping are the failure point. On a brick building with a flat roof behind a parapet, water enters at the coping, the parapet junction and the flashing between them — rarely in the field. A quote pricing only the membrane has priced the easy part, and it is why the same roof can be “replaced” twice and still leak.
Brick and mortar are part of the roof system here. Failing mortar joints on a parapet let water into the wall and out through the ceiling, presenting exactly like a roof leak. A competent St. Louis roofer will look at the masonry as well as the covering.
Flat roofs live on coatings. Kept coated, these systems last a long time. Neglected, ultraviolet degrades them and the whole assembly needs replacing.
Hail and freeze-thaw. The metro gets severe thunderstorm hail, and winters cycle across freezing repeatedly — hard on parapet caps and any water already inside masonry.
The city requires a contractor business licence. St. Louis’s Construction Industry Contractor Graduated Business Licence applies to all contractors working in the city.

- Class 4 impact-resistant upgrade: roughly $2,500–$7,000, stated to earn a 10–30% premium discount. Deductibles in hail-prone St. Louis zip codes commonly run $1,500–$5,000
St. Louis is a hail market with a deductible problem rather than a price problem. Deductibles in the hail-prone zips — 63017 and 63044 are named, along with St. Charles County — commonly run $1,500 to $5,000, which is a large share of a mid-range roof before insurance pays anything. That is what makes the Class 4 arithmetic above worth doing. The county code position is unusually well documented: St. Louis County enforces the 2015 IRC and IBC with local amendments, requiring Class A fire-rated roofing and ASTM D7158 or D3161 wind resistance, capping shingle layers at two, and setting attic ventilation at 1 square foot of net free area per 150 to 300 square feet with R-38 insulation. One local cost driver worth knowing before you compare quotes: the historic neighbourhoods — Lafayette Square, Soulard, the Central West End, Webster Groves — carry steep pitches, multiple slopes and dormers that raise labour, while the 1970s Chesterfield ranches are typically the cheapest per square foot in the metro. Booking late autumn or winter is stated to run 5 to 10 percent softer than peak season.
These are ranges local roofing companies publish for this metro rather than survey data, so treat them as a bracket to check a quote against, not a price list.
Two contract items: your wind and hail deductible in dollars, since $1,500–$5,000 is common in the hail-prone zips, and that the assembly meets the County’s Class A fire rating and ASTM D7158 or D3161 wind standard.

How this directory helps
Every roofer here is listed with business name, address and phone so you can verify them yourself.
Three questions sort St. Louis contractors. Ask what the quote covers at the parapet and coping, because that is where these roofs leak. Ask whether masonry repair is included or separate. And confirm they hold the St. Louis contractor business licence.
