roofing company
Gorilla Roofing replaces and repairs roofs across St. Louis City and St. Louis County: old brick homes in South City, flat roofs behind parapet walls, and ranches out in the county. The inspection is free, and you get a straight answer about what your roof needs.

Free roof inspection
Real jobs, real photos
We work in St. Louis every week
Since April, our crews have sent back photos from 26 roofs with a St. Louis address. They send them from the roof, while they work, so the office and the homeowner can see what's going on.
Every photo on this page comes from one of those jobs. No stock photos. We name the ZIP code, not the street, because these are people's homes.

Know the house
St. Louis roofs aren't all the same
City brick
Steep roofs on old boards
A lot of South City is brick homes with steep roofs, dormers, and chimneys. Under the shingles there is often a deck of old wood boards instead of plywood.
Boards are fine if they're sound. When the old roof comes off, we walk every board, photograph the bad ones, and replace only those. You see the photos before we do it.
Flats and two-families
Flat roofs and parapet walls
Many city homes and two-family flats have a flat roof behind a brick parapet. Leaks there usually start where the roof meets the wall, or in the wall itself.
We fix the brick and the roof on the same job. You don't need a mason and a roofer who have never met.
County homes
Ranches and split-levels
Out in the county, a lot of homes are ranches and split-levels with simple gable or hip roofs. These are the most straightforward roofs we do.
Price comes down to size, how many layers come off, and how much decking needs work. We'll tell you all three before you sign.
For the record
What St. Louis roofs have been through
2025 was a hard year. If nobody has been on your roof since then, it's worth a look. Hail damage often doesn't show from the street.

| 2023 | 18 | 27 | 1 |
| 2024 | 13 | 6 | 4 |
| 2025 | 104 | 26 | 7 |
| 2026* | 18 | 12 | 2 |
Hail up to 2 inches in Carondelet.
Sixteen reports of 75 to 80 mph wind, from Oakville to Bridgeton. Hail up to 2 inches in Carondelet.
A tornado from Clayton through Forest Park into North City, EF3 at its strongest. NOAA puts the damage in the city at $1.6 billion.
Hail up to 2 inches in Brentwood and Wedgewood.

Insurance claims
19 of our 26 were claims
Most of this year's St. Louis roofs were paid for by insurance. We get on the roof, photograph the damage, and tell you plainly whether it's worth a claim. If it isn't, we say so.
If you file, we meet your adjuster on the roof and build to the approved scope. You pay your deductible.

St. Louis roofing questions
Yes. South City is where a lot of our 2026 jobs were, in the 63109, 63110, 63111, 63116, and 63139 ZIP codes. We work across the county too.
Most homes land between $9,500 and $14,000 for a full replacement with CertainTeed Landmark shingles. Small, simple roofs can be $4,000 to $7,500. Steep city roofs with dormers sit toward the high end. The roof replacement cost guide breaks it down by home size and material.
Yes. We reset loose brick on the parapet and replace the flat roof on the same job, so the roof and the wall are sealed to each other properly.
