Top roofing companies in St. Louis, and the two lists that disagree

The single fact that this entire site was built around

Of the 222 companies in the file, 55 hold at least one hundred reviews. That is the point where a star average stops being an anecdote and starts being a measurement. And of those 55 companies, 49 of them are rated 4.7 or better.

Read that again, because it is the whole story. Once you require enough evidence for the rating to mean anything, the rating stops telling you apart. Nearly nine in ten survivors sit inside three tenths of a star of each other. Exactly three companies in the entire metro carry a hundred or more reviews and a rating below 4.5. The star column, which is the column every comparison site in this market sorts on and every roofing advertisement quotes, has almost no information left in it by the time you have made it trustworthy.

Which leaves review volume, and volume has the opposite failure. It measures exposure. A company that has knocked doors across three counties for a decade, or bought the top of the search results every spring, will out-collect a four crew shop that has never advertised, in this market and in every other market, permanently. The largest holding in the file is 1,834 reviews at 4.2 stars. The top ten companies between them hold 34 per cent of every review in the file. That is a map of who is loudest, and it is a genuinely useful map, but it is not a ranking of who is good.

So this site publishes both, side by side, and draws the disagreement rather than hiding it inside a composite score. And then it does the thing the disagreement makes unavoidable. If neither sort answers the question a homeowner is actually asking, a page that only sorts has not finished its job. So this one states five criteria of its own, prints them, and names one company at number one against them. That entry is an editorial pick and it is labelled as one, at the top of the ranking and in the disclosure at the foot of every page.

The split rule, which is the only chart on this site

Under every company below sits a strip. The filled square marks where that company lands on review volume, from the quietest listing in the file on the left to the loudest on the right. The hollow ring marks where it lands on star rating across the same 222 companies. When the two markers sit close together, the two ways of measuring that company agree with each other.

The connector turns red under one specific condition, chosen so that the mark means something rather than firing on every row: one measure has to place the company in the top quarter of the file while the other places it below the file's own median. That median is worth holding on to, because it is higher than most people expect. The median star rating across these 222 companies is 4.9. In this market a 4.8 is a below average rating, and a 4.2 is close to the floor.

How this ranking is put together

The entry at number one is our own editorial pick, assessed against the five criteria published in the How we rate box at the head of this sheet. The companies underneath it carry a short label each rather than a criteria score, because nobody has stood on their roofs on our behalf and we have nothing to mark them against. The star averages and review counts printed beside them are Google's figures rather than ours, read in a Google Maps pull dated 23 August 2026, and they belong to the businesses they describe. We publish no star rating and no review count for Keys Roofing, because the money site states neither.

   Best overall · our editorial pick

   Both of the sorts on this page answer a question about attention. Review volume answers how many people have spoken about a company. The star average answers how warm they were when they spoke. Neither one answers the question a homeowner is actually holding, which is whether this particular company will do this particular job properly. So rather than let the sort order pass itself off as an answer, this site states five criteria of its own, prints them, and puts at number one the company that meets all five.

   Keys does same-day installs. It publishes a 24 hour response time, and it is locally owned in greater St. Louis.

   Those three facts describe the practical shape of the company rather than the scorecard. Same-day installation is not a sixth criterion and it is not counted as one: the card below is still five criteria, and same-day work appears in it as evidence under owner led, because the scheduling of a crew is a decision only the person who runs that crew can make.

   • MetScope disciplineRoofing, gutters and downspouts, and nothing else. No siding, no windows, no commercial buildings, no general contracting.
   • MetWater handled end to endThe deepest gutter and downspout menu in this market, underground drainage included. Competitor research across greater St. Louis turned up no other roofer here that merchandises where the water goes once it has left the roof.
   • MetOwner ledThe owner runs the work, so the person who quotes the job is the person accountable for it. It is also what puts same-day installs on the table: Keys does them, and a same-day start is a scheduling decision that belongs to whoever controls the crew.
   • MetA stated shingle lineAtlas and Malarkey, named in the open, rather than whatever is cheapest that week.
   • MetLicensed and insuredStated plainly, and left plain. There is no badge, no tier and no number bolted onto it.
   • Total5 of 5 criteria met.

   That figure is a count of the criteria on our own scorecard and nothing else. It is not a Google star rating, it is not a review score, and it does not belong on the same axis as the two columns printed beside every company below. We publish no star rating and no review count for Keys Roofing, because the company publishes neither one itself.

Positions are percentile ranks across all 222 companies, with tied values sharing the midpoint. Because 78 companies are tied at a perfect 5.0 and the median rating is 4.9, the rating axis is heavily compressed at the top, which is itself the finding on sheet six. The strip is not a score and never adds the two measures together.

A ranking can tell you which companies exist and roughly how much noise each one has made. It cannot tell you what to ask, what to read, what a written scope has to contain, where a company is actually registered, or what Missouri does and does not require. Those are the eight pages that follow the two lists, and not one of them asks you to take a ranking on trust.
