Advertising disclosure: Keys Roofing publishes this page and is shown here as a featured placement, separately from the data-ranked list below. It is not a ranked entry and was not scored.
Methodology
Ranked by Google review count, highest first, among businesses Google categorises as roofing or gutter contractors in greater St. Louis that carry both a star rating and at least 20 reviews. Data pulled from Google Maps and compiled August 2026. Review count measures how much feedback a company has collected, not the quality of its work, and an older company will almost always out-collect a newer one. This is one data pull rather than a census of every roofer in the metro, so a company absent from it is not necessarily absent from the market.

What this list cannot tell you
Review count rewards age and volume. A company that has been trading for twenty years will out-collect a better company that started in 2022, and a high-volume storm operation will out-collect a careful small crew by a wide margin. Read it as a measure of how much public feedback exists, then go and read the feedback itself.
The things that actually separate roofing companies do not appear in this table at all: whether the crews are employees or day labour, whether the person who sells the job is ever on site while it is done, what happens when something goes wrong two winters later, and whether the company will put a written scope in your hand before asking for a signature.
The work, and its limits
Keys does roofing, gutters and downspouts. It does not do siding, windows or general contracting, and saying so is more useful than a longer list would be. Shingles are Atlas and Malarkey.
- Tear-off and full replacement, decking replaced where it has softened
- Leak tracing and repair: flashing, boots, valleys, fasteners
- Documented inspections, photographs and a written scope in your hand
- Seamless gutter rolled on site, guards, resealing and re-hanging
- Downspout reroutes, extensions and buried drainage to a proper outlet
Drainage is the unusual one. Most roofing companies here stop at the gutter and leave the water to find its own way, which it does, usually into a basement.

Before you sign anything
Get the scope in writing first. It should say what is being torn off, what is going back on, what happens when soft decking appears, and who carries the workmanship warranty as distinct from the shingle warranty. Ask whether the crew are employees or subcontractors and whether the salesperson attends the job.
Two warning signs specific to this state. A contractor offering to cover or rebate your deductible is offering something RSMo 407.725 bars. So is one promising to negotiate your insurance claim. Both tell you the company is comfortable operating outside the rules, which is worth knowing before it is on your roof.
Questions people actually ask
Why does a roofing company publish a list of its competitors?
Because the alternative in this market is a page pretending to be independent while ranking whoever paid for it. The ownership is disclosed at the top, Keys is not in the ranked list, and the sort is on a public number Keys does not control.
Does a high review count mean a company is good?
It means a lot of people have said something. It rewards age and volume, so a twenty year old firm will out-collect a better one founded in 2022. Read the count as a measure of how much feedback exists, then read the feedback.
Why is a company I know missing from the list?
This is one data pull rather than a census, and a business that is not categorised as a roofing contractor on Google, or that has no rating, will not appear. Absence from the list is not absence from the market.
