To perform roofing work in the state of New Mexico, you’re required to o btain your professional roofing contractor license. One crucial aspect of licensure is taking and passing the NM GS-21 Roofing License Exam and the accompanying Business and Law Exam. There are also additional requirements that must be met. 

By holding a GS-21 Roofing License, you’ll be able to lawfully alter, repair, and install roofing systems on existing or new roof decks to create watertight and weatherproof protective barriers over various structures. These barriers can be installed with or without insulation using pitch, tar, asphalt, sealants, shakes, roof tile, felt, shingles, urethane, slate, or roof tile. 

Such labor also includes the preparatory work needed to get a roof deck or roof to a workable condition. You’ll be able to lawfully cut, shape, fabricate, and install sheet metal for roof coatings, gutters, and downspouts as well. Finally, you may install and repair prefabricated chimneys at or near metal flues, roof lines, or other components related to roofing projects. 

How to Get a New Mexico Roofing License


You must meet certain criteria to qualify for a roofing license. Contact the New Mexico Regulation and Licensing Department to learn more about the specific criteria and begin the application process. 

To avoid experiencing delays in the processing of your materials, make sure you fulfill each of the following requirements before submitting your application. 

GS-21 New Mexico Roofing License Requirements


In addition to passing the two previously mentioned tests, you must provide proof of at least two years of relevant practical experience at the level of a foreman in the roofing trade.  

In addition, you’ll be asked to show that you possess training classifiable as technical. This technical training must have been obtained at an accredited university or college. It can also have been gained from a manufacturer’s training program, apprenticeship program, or technical vocational institute that’s accredited by the state.  

Technical training can be an acceptable substitute for work experience if it’s applicable to the circumstances under which you plan on working. In this case, each year of training counts as a one-half year of experience. However, technical training cannot comprise more than one-half of the total work experience required. 

Finally, each applicant for the New Mexico roofing license must become an approved Qualifying Party. 

The Business and Law Exam and the GS-21 Roofing Exam


The Business and Law Exam is an open-book test featuring a total of 50 questions. You’ll have 130 minutes to take it, and you must answer 75% of the questions correctly to pass. Topics that are covered include project management, environment and safety, and business organization. 

The GS-21 Roofing Exam is another open-book test that contains 60 questions, and you’ll have 150 to complete it. Again, you must answer 75% of the questions correctly. Topics include roofing components, plan reading, surface preparation, safety, and others.
