How to Start a Roofing Business in New Mexico: GS-21 License and Insurance

If you plan to replace shingles, install membrane, or repair flashing for paying customers in New Mexico, you need to get the licensing right before your first bid. The roofing license is issued by the Construction Industries Division (CID) of the Regulation and Licensing Department, and it is issued to a business entity, not to an individual working alone. The sequence is straightforward: confirm the classification, certify a qualifying party, form the entity, register for taxes, carry insurance and bond, then apply. This guide walks through that order.

This article is informational content, not legal or tax advice. Licensing rules, fees, and insurance requirements change, and your situation may raise questions this article cannot answer. Talk with a New Mexico attorney and a CPA before you form the business or sign customer contracts, and confirm every figure below with the agency named.

What You Need Before You Start

Gather these items before you file anything.

• A qualifying party who holds CID certification and has at least four years of work experience within the prior 10 years. This person sits the exam and must either work for the business or own it.
• A business entity, such as a limited liability company (LLC) or a corporation, that employs the qualifying party or is owned by them.
• The $30 non-refundable CID application fee, plus the GS-21 license fee of $50 a year or $100 for two years.
• A $10,000 corporate surety bond, which is required at licensing and at every renewal.
• Workers' compensation coverage that meets state law, as explained in Step 5.
• The entity filing fee: $50 for Articles of Organization (LLC) or $100 for Articles of Incorporation (corporation).
• A federal Employer Identification Number (EIN) from the IRS and a free Business Tax Identification Number (BTIN) from the Taxation and Revenue Department.
• A registered office and a registered agent in New Mexico.
• A city or county business registration, if the place where you work requires one.

Step 1: Confirm Your Classification With CID

GS-21 Roofing is a specialty classification licensed by CID under 14.6.6 NMAC. Before you apply, confirm that GS-21 covers the work you plan to bid. New Mexico also has a GB-98 general building classification, and a GB-98 license covers GS scopes. That means a general building license may fit a business that does roofing alongside other building work better than a roofing-only specialty does. Ask CID which classification matches your scope, and ask for the answer in writing if you can get it.

Write down the exact scopes you plan to perform in your first year: tear-off, re-roofing, flat roof membrane, metal roofing, and repairs. Describing your work accurately now prevents the common problem of holding a license that does not cover the job you actually take.

Step 2: Certify a Qualifying Party

The qualifying party is the person whose experience and exam result qualify the business for the license. Under 14.6.3 NMAC, the qualifying party needs four years of work experience within the prior 10 years to sit the CID exam. A passing score is 75%.

Start building your documentation now. Keep employer letters, signed job descriptions, dated project records, and tax or payroll records that show the roofing work you performed. Confirm with CID which documents it accepts as proof of experience, since the standard for acceptable evidence is set by the agency, not by this article.

If the qualifying party is not you, the business must still employ them or be owned by them. A license held by a company with no qualified person behind it can cause problems at renewal and during a complaint investigation.

Step 3: Form the Business Entity

Most roofing owners choose an LLC because it is the least expensive entity to form and maintain in New Mexico. The state's Secretary of State handles all business filings online through the SOS Enterprise Business Filing System at https://enterprise.sos.nm.gov/.

• LLC filing fee: $50 for Articles of Organization. An LLC files no annual or biennial report with the Secretary of State, and it has no LLC franchise tax.
• Name rules: The name must include the words limited liability company or limited company, or an abbreviation such as LLC or L.L.C. It must also be distinguishable from existing New Mexico entities. If you will trade under a different name, such as a trade name for your crews, that name must be stated in the articles of organization. New Mexico has no statewide DBA or assumed-name registration, so the articles are where the name goes.
• Name reservation: $20 for 120 days, not renewable.
• Expedited handling: $150 for same business day service when received before 2:00 p.m. (next business day if received later), or $100 for two business day service. Both are paid separately and are nonrefundable.
• Processing time: The Secretary of State does not publish a standard turnaround. Filers are notified by email of approval, rejection, or a required correction, so check your inbox closely after you submit.
• Registered agent: Every LLC needs a registered office in New Mexico, which can be your business address, and a registered agent who is either a New Mexico resident or a qualifying business entity with a New Mexico place of business at that office. Changing the agent or office costs $20 for an LLC.

If you form a corporation instead, the costs are higher. The filing fee is $100, the first biennial corporate report costs $25 and is due within 30 days after the certificate of incorporation is issued, and later reports are due biennially. Corporations also owe a $50 annual corporate franchise tax reported on form CIT-1, plus the flat 5.9% corporate income tax on taxable income for taxable years beginning on or after January 1, 2025. A default pass-through LLC does not owe the franchise tax. Ask a CPA which structure makes sense for your expected profit and payroll before you choose.

Step 4: Register for Taxes

New Mexico has no general statewide business license. The Taxation and Revenue Department (TRD) issues a free BTIN, and that number is a tax registration, not a license. Do not treat it as your roofing permission to operate. Your roofing authority comes from CID.

New Mexico also has no sales tax. Instead, it levies a gross receipts tax on the seller. The state rate is 4.875%, and combined state plus local rates run from 5.25% to 9.4375% under the schedule effective July 1, 2026 through June 30, 2027. How that tax applies to a roofing job, including the split between labor and materials, is a question to put to TRD and your CPA before you quote. Do not assume your bid can be priced without it. You can find registration guidance at the TRD registration page and general agency information at tax.newmexico.gov.

Step 5: Carry Workers' Compensation and Liability Insurance

Licensees must comply with New Mexico's workers' compensation law under NMSA 60-13-23. Employers with three or more workers are generally covered by the Workers' Compensation Act. Roofing is physically dangerous work, so this requirement is the one to treat as non-negotiable. Check with CID and the Workers' Compensation Administration to confirm how the rule applies to your crew size, to owners who work on the roof, and to subcontractors you hire, because the answer can depend on how each worker is classified.

General liability insurance is a separate question. Check with CID for any minimum liability limit for roofing contractors, and do not assume a number. In practice, many commercial customers, property managers, and general contractors will ask for a current certificate of insurance before they sign a contract. Ask your insurer and your customers what they require before you set your coverage.

Step 6: Post the $10,000 Surety Bond

A $10,000 corporate surety bond is required at licensing and again at every renewal under 14.6.3.8 NMAC. The bond amount is set by the state, but the premium you pay is set by the surety company. The premium depends on your credit and business history, so get quotes from more than one surety before you apply. Do not budget for the bond as if its cost equals its face amount.

Step 7: Apply to CID and Pass the Exam

Submit your CID application once the qualifying party is ready to sit the exam and the entity is formed. The fees under 14.5.5.8 NMAC are a $30 non-refundable application fee and the GS-21 license fee of $50 a year, or $100 for two years. The application fee is not returned if the application is denied or withdrawn, so confirm eligibility before you pay.

Processing times for CID applications vary. Ask CID for its current processing estimate, and plan your first bid date around that answer rather than a guess. Confirm the application format and the exam scheduling process with CID directly.

Step 8: Register With Your City or County

A state license does not replace local rules. Cities and some counties charge their own flat annual business registration. The amount and the process vary by jurisdiction, so check with the city or county where you will work. Major markets include Albuquerque, Las Cruces, Rio Rancho, and Santa Fe, but this article does not state their fees, and you should confirm the current amount and filing method with each one before you start taking jobs there.

Step 9: Plan Your Renewals

The GS-21 license must be renewed on the schedule CID sets. Budget $50 a year, or $100 if you choose a two-year renewal, and renew the $10,000 bond at the same time. Put these dates on a calendar and set reminders at least 60 days early, so a lapse does not stop your work during a busy season.

Your entity has its own deadlines. An LLC files no annual report, but a corporation must file its biennial report and pay the franchise tax on time. Separately, TRD gross receipts reporting continues for as long as you are registered.

Common Mistakes to Avoid

• Treating the BTIN as a license. A free BTIN registers you for taxes. It does not authorize roofing work.
• Bidding before the license is issued. Signing a contract or accepting a deposit before CID approval creates exposure you may not be able to undo.
• Assuming an LLC files an annual report. New Mexico LLCs file no annual or biennial report with the Secretary of State. Corporations are different.
• Looking for a state DBA filing. New Mexico has no statewide assumed-name registration. Put your trade name in the articles of organization if you will use one, and check local rules for anything more.
• Weak qualifying party records. Keep experience documents organized from the start. Reconstructing four years of job history from memory is slow and often incomplete.
• Hiring crew before confirming workers' compensation. Once you have three or more workers, the coverage requirement generally applies. Confirm your coverage before the first hire.
• Forgetting the bond at renewal. The $10,000 bond must be in place at every renewal, not only at initial licensing.
• Using a name without LLC in it. The entity name must carry the required designation, so a name like Smith Roofing without LLC will not work as your legal entity name.

What Results to Expect

Once your entity is formed, your qualifying party is certified, your insurance and bond are in place, and CID has issued the GS-21 license, you may be able to bid on roofing work in New Mexico under that authority. It can help to start the paperwork and the qualifying party's documentation before you sign a lease or buy trucks. Your actual timeline will depend on how quickly you gather records, how CID processes your file, and how your city handles its own registration.

A license does not guarantee customers or revenue. It is a permission to work, and the results you get from it depend on your pricing, reputation, and the quality of your work.
