How to verify a Mississippi contractor's license

If you manage a building in Mississippi and you are about to spend real money on its roof, the cheapest piece of due diligence available to you is free and takes about two minutes. The Mississippi State Board of Contractors publishes a searchable register of every contractor it licenses, and a number that does not resolve there is a number worth asking about before anything gets signed.

First: Mississippi keeps two separate registers

This is the part that trips people up. The board licenses residential contracting and commercial contracting separately, in two different indexes, and a company can appear in one and not the other. The same business will even carry a different internal ID in each index, so finding a roofer in the residential register tells you nothing about whether they are licensed for your warehouse. Ask which credential they hold for the work you are buying, then check that index specifically.

What Mississippi calls the commercial credential is a Certificate of Responsibility. It is held by the company and tied to a qualifying individual, and it is a different thing from a residential license, not a bigger version of one.

What the law actually requires

The thresholds matter, because a lot of roofing marketing (ours included, at one point) blurs them into a blanket claim that all commercial work requires a license. That is not what the board says. In MSBOC's own words: "All contractors and subcontractors performing work on commercial jobs over $50,000, including equipment installation, are required to have a commercial license issued by MSBOC."

On the residential side the figure is much lower: "All contractors performing new residential construction over $50,000, residential remodeling or additions over $10,000, or residential roofing over $10,000, are required to have a license issued by MSBOC." A roof replacement on a house is almost always over that $10,000 roofing figure, which is why the residential license is not optional in practice even though the law states it as a threshold.

Two honest caveats. Below the state thresholds, your city or county may still have its own licensing, permitting or registration requirements, and MSBOC does not administer those, so a state answer is not automatically the whole answer. And none of this is legal advice: it is what the board publishes, quoted so you can go read it yourself.

How to run the check

What a license does not tell you

A current license means the state has qualified the company to do the work at that size. It is a floor, not a recommendation. It says nothing about whether the crews are any good, whether the company carries insurance today, whether it pays its suppliers, or whether it will answer the phone in year three of a warranty. Those are separate checks, and on a commercial roof they matter as much as the license does.

The storm-chaser version of this problem

After a hurricane or a hail event, crews arrive from out of state, work fast, and leave faster. Some are licensed here and some are not, and the ones that are not are precisely the ones who will tell you a license is a formality. The register does not care how convincing anybody was on your driveway. If the number does not resolve, you have your answer, and you have it before you have paid anyone.
