Exam Details

The New Mexico Roofing Contractor (GS-21) exam is administered through PSI for New Mexico contractor licensing. Candidates must be approved before scheduling the required examination. Once eligibility is granted, candidates can schedule the exam through PSI and complete the test by computer at an approved testing location.

The GS-21 Roofing Contractor trade exam includes 60 questions. Candidates are allowed 150 minutes to complete the examination. The required passing score is 75%, which equals 45 correct answers. Because this is a timed examination with multiple references, candidates should prepare to read each question carefully, identify the subject area, select the most likely book, and locate the answer efficiently.

The GS-21 exam is focused on roofing contractor knowledge, roof construction practices, residential and commercial code requirements, roofing materials, steep-slope systems, low-slope membrane systems, tile roofing, safety, estimating, and installation methods. Candidates should prepare to work with both building code references and roofing trade manuals. The approved references supplied in this package show that preparation should include OSHA safety, New Mexico building code provisions, IBC and IRC roofing requirements, roofing construction and estimating, NRCA steep-slope guidance, NRCA membrane roofing guidance, and concrete and clay tile installation practices.

All Specialty Roofing - Commercial Contractor candidates are also required to pass the Business Management and Law for Contractors exam. Candidates should review their full licensing path so they understand both the trade examination and any business or law requirements connected to New Mexico contractor licensing.

The GS-21 exam should be approached as both a trade knowledge test and a reference navigation test. Questions may require candidates to identify safe work practices, understand roofing terminology, locate building code provisions, recognize proper installation methods, calculate or interpret estimating-related information, or apply roofing reference material to field conditions. Candidates should study the structure of each reference and practice locating information before exam day.

Open Book Test

The New Mexico Roofing Contractor (GS-21) examination is an open book test using approved references. Candidates are responsible for bringing their own approved materials to the examination center. This highlighted and tabbed package includes the listed references for GS-21 preparation.

Open-book testing still requires serious preparation. The references in this package are detailed, and the exam environment is timed. Candidates who are unfamiliar with the books may lose valuable time searching for answers. Candidates who have practiced with their references can move more confidently between chapters, tables, definitions, roofing details, building code provisions, safety rules, and installation guidance.

Reference materials must be bound and may be highlighted, underlined, and indexed before the examination session. Permanent tabs are allowed. Temporary tabs, including Post-it notes, are not allowed and must be removed before the exam begins. Reference materials containing writing are not allowed into the examination, and candidates are not permitted to write in the references during the testing session.

This highlighted and tabbed package supports the open-book format by helping candidates organize their study references in a practical way. The tabs help candidates return to major subject areas, while the highlighting helps draw attention to key provisions and commonly reviewed material. Candidates should still study consistently, practice reference lookup, and become familiar with the organization of each book before the exam.

Licensing Steps

Candidates pursuing the New Mexico Roofing Contractor GS-21 classification should begin by reviewing the state contractor licensing process and identifying the correct classification. The GS-21 classification is associated with roofing contractor work, so candidates should make sure they are applying for the proper license type and required examination.

A practical preparation path includes identifying the correct GS-21 classification, completing the required application or qualifying party approval process, receiving examination eligibility, scheduling the required trade exam, reviewing the approved reference list, studying consistently, and arriving at the testing center with proper identification and approved materials.

Contractor candidates may also need to satisfy the Business Management and Law for Contractors requirement as part of the New Mexico contractor licensing process. Candidates should review their full licensing path so they understand the trade examination, business requirement, application, documentation, experience, financial, bonding, registration, and administrative steps connected to the license.

After passing the required examination, candidates should complete any remaining New Mexico contractor licensing requirements. Passing the GS-21 exam is an important step, but candidates are still responsible for meeting all applicable requirements before a license can be issued or maintained.

Candidates should keep application documents, eligibility notices, exam scheduling confirmations, reference lists, score reports, and licensing correspondence organized. Good recordkeeping helps reduce confusion and allows candidates to focus more attention on preparation and the remaining licensing steps.

State Requirements

New Mexico contractor licensing is connected to the Construction Industries Division of the New Mexico Regulation and Licensing Department. Contractors performing roofing work must understand applicable building code requirements, construction safety rules, trade practices, and installation standards that affect roofing construction in New Mexico.

The New Mexico Commercial Building Code (NMAC 14.7.2), 2021 and the New Mexico Residential Building Code (NMAC 14.7.3), 2021 are important because they contain state-specific building code provisions and amendments. Candidates should study these references alongside the International Building Code, 2021 and the International Residential Code for One- and Two-Family Dwellings, 2021 to understand both model code requirements and New Mexico-specific code provisions.

Roofing work may involve roof assemblies, roof coverings, underlayment, flashing, roof drainage, roof slope, reroofing, roof ventilation, fire classification, weather protection, and materials. Candidates should be comfortable using building code references to locate requirements that affect residential and commercial roofing work.

The Code of Federal Regulations - 29 CFR Part 1926 (OSHA) supports preparation for construction safety topics such as fall protection, ladders, scaffolds, personal protective equipment, hazard communication, material handling, tools, and jobsite hazard control. Roofing work often involves elevated work, edge hazards, ladders, roof access, weather exposure, hot materials, power tools, and material handling, so safety knowledge is essential.

Test Information and Study Materials

The New Mexico Roofing Contractor (GS-21) exam requires preparation across code, safety, estimating, and trade references. Candidates should study the approved references as a complete set rather than treating each book as separate and unrelated. Roofing construction involves materials, layout, weather protection, slope, ventilation, drainage, safety, flashing, reroofing, residential code requirements, and commercial code requirements.

Roofing safety should be a major part of the study plan. Candidates should review OSHA requirements for fall protection, ladders, scaffolds, personal protective equipment, hazard communication, material handling, tools, and jobsite hazards. Roofing contractors often work at heights and around roof edges, openings, ladders, steep slopes, weather exposure, and heavy materials, making safety knowledge especially important.

Residential roofing code study should include roof coverings, roof slope, asphalt shingles, underlayment, flashing, roof ventilation, reroofing, roof deck conditions, and weather protection. The IRC and New Mexico Residential Building Code support preparation for one- and two-family dwelling roofing requirements.

Commercial roofing code study should include the IBC and New Mexico Commercial Building Code. Candidates should review roof assemblies, fire classification, roof coverings, drainage, reroofing, materials, weather protection, and commercial building code provisions that affect roofing work.

Steep-slope roofing should be studied through the NRCA steep-slope manual and the applicable code references. Candidates should review roof slope, deck conditions, underlayment, flashings, shingles, tile, metal components, ventilation, drainage, roof penetrations, valleys, ridges, hips, eaves, rakes, and good installation practices.

Low-slope and membrane roofing should be studied through the NRCA membrane roofing manual. Candidates should review membrane types, insulation, vapor considerations, attachment methods, flashings, roof drainage, roof decks, penetrations, parapets, edge conditions, maintenance, and commercial low-slope roofing practices.

Concrete and clay tile roofing should be studied directly from the tile installation manual. Candidates should review tile materials, layout, underlayment, battens where applicable, fasteners, flashing, roof slope, weather exposure, installation sequence, and roof deck preparation. Tile roofing has specific installation practices, so candidates should become familiar with the structure of this reference.

Roofing estimating and construction planning should also be included in preparation. Roofing Construction and Estimating supports study of measuring, material quantities, labor considerations, roof layout, waste, project planning, and practical installation methods. Candidates should understand how estimating connects to roofing construction and job management.

Flashing and weather protection should receive special attention. Roof performance depends heavily on details at valleys, walls, chimneys, skylights, penetrations, edges, parapets, curbs, drains, and transitions. Candidates should study flashing requirements across the roofing references and building codes because these details are important for water control and long-term roof performance.

Candidates should also practice reference navigation. A safety question may point to OSHA. A residential code question may point to the IRC or New Mexico Residential Building Code. A commercial code question may point to the IBC or New Mexico Commercial Building Code. A steep-slope or membrane system question may point to an NRCA manual. A tile question may point to the Concrete and Clay Tile Installation Manual. An estimating question may point to Roofing Construction and Estimating. The ability to identify the likely reference quickly is a key part of open-book exam preparation.
