How we verify listings | Roof Leak Repair

A city's license page, when one exists, traces every contractor name on it back to an actual license or registration file, kept by whichever state agency covers that company. We show the status, class, and expiration next to each one, with a link back so you can pull up the original record yourself.

A city without a license page gets its roof leak repair names from Google Maps instead, highest-rated first once review count is factored in. That's a different thing entirely from a license file, and the page says so plainly.

We don't inspect roofs, score repair quality, or take a side in a dispute between a homeowner and a contractor. That's outside what a license record, a Google rating, or this site can tell you.

Each license listing also links to its own record on the state agency's website, so you can check it at the source.

What we check before a business is listed

The license is active in the registry when we pull the data. Businesses with any other status are left out.
The license hasn't passed its expiration date.
The business matches roof leak repair. We match on the registry's specialty classification, the registered business name, or both. That's why every listing shows its license class: check that it fits your job.
The business address on record is in a city with at least 3 matching businesses. Smaller cities don't get a page yet.

What each listing shows

Business name: As registered with the state, with capitalization tidied up.
Category: Our label for why the business is listed on this site, based on its specialty or registered name.
License class: The specialty the registry lists for the business, for example General or Roofing.
License number: The contractor license or registration number the registry uses.
Status: Active as of the date we checked. We don't list any other status.
Effective and expiration dates: When the current license took effect and when it expires, as the registry reports them.
Business type: For example limited liability company, corporation or individual, shown on each business's profile when the registry provides it.
City and ZIP: From the business address on record. They show where a business is based, not the area it serves, which is why we say “based in”.
Verify license: A link to the business's own record on the state agency's website.

What we leave out on purpose

We don't publish phone numbers, street addresses or the names of owners and principals, even where the registry lists them. The business name is the only name we show.

How often we refresh

We re-pull the registry data and rebuild these pages from it. Every city page shows the date its listings were last checked; the current listings were checked on September 30, 2026. A license can change between our checks, so the Verify license link, which opens the live record, is always the final word.

Top-rated lists

The search behind this page is "roof leak repair" on Google Maps, run once per city. A result has to be open now, actually work in the trade rather than sell parts or resell leads to roofers, sit within a size-scaled radius of downtown, roughly 6 to 25 miles, and carry 3 or more Google reviews before it counts.

From there we weigh the star rating against its review count, so one glowing review from a single customer doesn't outrank a company hundreds of people rated slightly lower. Five qualifying companies is the floor for a city to get a page, and ten names is the ceiling for the list.

None of that is the same as checking credentials. A rating reflects what past customers thought of a company, not whether it currently holds a license, a registration, or insurance paperwork. Before anyone gets on your roof, find out which license or registration number the job actually calls for, ring up the office that issues it, request proof of insurance in writing, and hold the last payment until the leak is actually fixed.

The details, the same on every top-rated page (3,271 city pages on this site):

One Google Maps search per city for “roof leak repair”, for cities of 10,000 or more people where this site has no license page. In 409 of those cities, where that search turns up too few businesses for a list, the list comes from the broader “roofing contractor” search, filtered the same way.
Left out: businesses marked closed, businesses outside a matching Google category (stores, suppliers and showrooms among them), businesses far from the city center (about 6 to 25 miles, depending on the city's size), businesses with fewer than 3 reviews, and names that are a person's name or belong to a lead marketplace or a big-box store.
Ranked by a Bayesian average of the Google rating, (rating × reviews + 4.3 × 15) ÷ (reviews + 15), so a 5.0 from 3 reviews ranks below a 4.8 from 300.
A city needs at least 5 businesses that pass; the page shows the top 10.
Each listing shows its rank, Google rating, number of Google reviews, Google category, the town and ZIP in its address, and a link to its Google Maps listing. No phone numbers, websites, street addresses or review text.
Ratings were checked between September 2026 and October 2026. They change every day, so open the Google reviews link for the current figure.

A rating is not a license check and not an endorsement. Before you hire anyone, ask for the license or registration number your state or city requires and check it with the office that issued it.

What we don't do

We don't review or endorse contractors, and a listing isn't a recommendation. License listings are sorted alphabetically; top-rated lists are ranked only by Google rating and review count, as described above. No business pays to be listed, to be left off or for its position. If we ever add paid placements, they will be marked Sponsored. How we make money.

Something wrong?

Business owners can claim a listing to ask for a correction, or ask us to remove it.
