Exam Details

The New Mexico Roofing Contractor (GS-21) exam is a trade exam for candidates pursuing the GS-21 roofing contractor classification. The exam includes 100 questions, has a 310-minute time limit, and requires a 75% passing score.

The exam focuses on trade knowledge connected to roofing systems, New Mexico commercial and residential building code provisions, International Building Code and International Residential Code navigation, OSHA construction safety, steep-slope roofing, membrane roofing, roof coverings, flashing, underlayment, drainage, tile roofing, roofing estimating, installation procedures, job-site safety, and contractor responsibilities.

GS-21 candidates should prepare for both technical trade content and contractor business law content. The trade portion measures knowledge related to roof assembly requirements, roofing materials, reroofing awareness, roof slope, roof drainage, flashing details, underlayment, roof coverings, tile roof installation, membrane roof systems, steep-slope roof systems, OSHA safety standards, code navigation, roofing measurements, estimating, and field procedures. Business law preparation supports the administrative, legal, and project-management side of contractor licensing. This Ultimate package includes the supplied technical references, business law materials, course access, and Application Service so candidates can study with a more complete preparation plan.

Important study areas may include OSHA construction safety, fall protection awareness, ladder and scaffold safety awareness, New Mexico Commercial Building Code provisions, New Mexico Residential Building Code provisions, International Building Code roofing requirements, International Residential Code roofing requirements, roof covering types, flashing, underlayment, roof slope, roof drainage, membrane roofing, steep-slope systems, concrete and clay tile installation, estimating, material calculations, contractor licensing rules, contracts, project management, and business law topics.

Because the GS-21 exam is tied to roofing contractor work, preparation should focus on both code knowledge and practical field application. Candidates should understand how roof assemblies protect buildings, how different roof coverings are installed, how flashing and underlayment prevent water intrusion, how safety standards guide roofing work, and how building code requirements support durable and compliant roofing installations.

Open Book Test

The New Mexico Roofing Contractor (GS-21) exam is an open book test. Candidates may use approved references during the exam, but the books must comply with examination rules. Open book testing still requires strong preparation because candidates must recognize the topic, select the correct reference, locate the correct information, and apply it within the time allowed.

Reference navigation is one of the most important skills for this exam. Candidates should practice using tables of contents, indexes, code chapters, definitions, OSHA subparts, roofing code sections, NRCA manual sections, roof system details, estimating formulas, figures, tables, installation diagrams, and tile roofing guidance. The goal is to become comfortable moving through each book before test day, not learning the layout for the first time during the exam.

Books used in the exam room are typically expected to be bound, approved, and free of loose papers or added writing. Highlighting, underlining, and permanent tabs may be allowed when they follow testing rules. Candidates should avoid temporary sticky notes, loose inserts, handwritten notes, copied pages, and any added material that could cause a reference to be rejected at the testing site.

A strong open book study routine includes reading a topic, locating the related reference section, answering practice questions, and repeating the lookup process until it becomes familiar. For the GS-21 exam, candidates should pay close attention to OSHA, New Mexico Commercial Building Code, New Mexico Residential Building Code, International Building Code, International Residential Code, Roofing Construction and Estimating, the NRCA roofing manuals, Concrete and Clay Tile Installation Manual, and business law materials connected to contractor licensing.

Licensing Steps

New Mexico contractor licensing is handled through the New Mexico Construction Industries Division. PSI is involved in New Mexico contractor licensing paperwork and contractor examination services. Candidates pursuing the GS-21 classification should follow the state licensing process for the applicable contractor license and qualifying party requirements.

A practical preparation path begins with identifying the correct classification for roofing contractor work. Candidates should review the GS-21 classification, confirm the required experience, complete the appropriate qualifying party application materials, and submit the required documentation for approval. Once approved, candidates can schedule the required examination and begin focused preparation using the course and included references.

The Application Service included with this Ultimate package helps support candidates through the application side of the process. Application support can help students stay organized, understand the paperwork involved, and move through the required steps with clearer direction. Candidates remain responsible for meeting all state requirements and submitting accurate information.

Business law preparation is also important for contractor licensing. Contractors are expected to understand licensing rules, contracts, project management, business operations, safety responsibilities, financial obligations, and compliance requirements. The business law materials included with this package support that side of preparation.

After the required exam steps are completed, candidates continue through the remaining licensing requirements. These may include submitting passing score reports, completing contractor license paperwork, providing business entity information, meeting bonding or workers’ compensation requirements when applicable, and satisfying other state licensing documentation. Candidates should keep names, addresses, business information, application details, and exam records consistent throughout the process.

State Requirements

The New Mexico GS-21 classification applies to roofing contractor work. This classification is associated with roof coverings, roof assemblies, steep-slope roofing, membrane roofing, concrete and clay tile roofing, flashing, underlayment, roof drainage, roofing safety, building code compliance, and related contractor responsibilities performed under New Mexico requirements.

Roofing contractor work may involve reviewing plans and specifications, preparing roof surfaces, installing roof coverings, applying underlayment, installing flashing, working with steep-slope systems, installing membrane roofing systems, working with concrete and clay tile roof systems, coordinating roof drainage, following safety requirements, and preparing work for inspection or project acceptance where applicable. Candidates should understand how each part of the roofing system supports weather protection, durability, safety, serviceability, and code compliance.

The GS-21 classification is a roofing contractor classification and should not be treated as an unlimited general construction, structural, mechanical, plumbing, electrical, sheet metal, or exterior envelope contractor authorization. Work outside the classification may require a different license classification or additional qualifications. Candidates should study the classification scope carefully so they understand what the license classification allows and where the classification stops.

For licensing preparation, candidates should understand both the technical scope of GS-21 roofing contractor work and the contractor responsibilities connected to performing regulated construction work in New Mexico. That includes contractor licensing rules, business obligations, job-site safety, building code compliance, roofing installation quality, project documentation, customer communication, inspection readiness when applicable, and professional conduct.

Test Information and Study Materials

This Ultimate package supports GS-21 roofing contractor exam preparation with a focused set of OSHA safety, New Mexico building code, International Building Code, International Residential Code, roofing estimating, NRCA roofing manual, tile roofing, and business law materials, along with 1 year of course access and Application Service. The included references provide the technical foundation for GS-21 preparation, while the online course access helps organize study time and gives candidates a structured way to review roof systems, building code requirements, roofing safety, installation practices, estimating, and business law topics.

A strong GS-21 study routine should begin with the major roofing areas represented by the supplied references. Candidates should understand how roof systems are selected, how roof slope affects materials, how flashing and underlayment protect against water intrusion, how membrane and steep-slope systems differ, how tile roofing is installed, and how building code requirements guide roof assemblies.

For OSHA construction safety study, candidates should review fall protection awareness, ladder use, scaffolding awareness, personal protective equipment, hazard communication, tools and equipment, material handling, roof edge safety awareness, and general job-site safety responsibilities. Roofing work involves elevated work areas, weather exposure, materials handling, and fall hazards, making safety preparation especially important.

For New Mexico building code study, candidates should review state commercial and residential building provisions, adopted code language, amendments, roofing requirements, roof covering provisions, roof assembly topics, weather protection, fire classification awareness, and New Mexico-specific compliance topics. Candidates should become comfortable moving between the New Mexico code references and the IBC or IRC when preparing for open book lookup questions.

For International Building Code study, candidates should review commercial roof assemblies, roof coverings, fire classification awareness, structural provisions, weather protection, drainage awareness, definitions, tables, and code navigation. The IBC supports preparation for commercial roofing-related questions and general building code application.

For International Residential Code study, candidates should review residential roof coverings, underlayment, flashing, roof slope requirements, roof ventilation awareness, roof drainage awareness, weather protection, and residential code organization. The IRC supports preparation for one- and two-family dwelling roofing work.

For steep-slope roofing study, candidates should review roof slope, underlayment, flashing, fastening awareness, shingles, tile systems, roof penetrations, valleys, ridges, eaves, rakes, drip edges, and weather protection details. Steep-slope roof systems require careful installation because water shedding depends on proper overlap, flashing, and material application.

For membrane roofing study, candidates should review low-slope roofing concepts, membrane types, insulation awareness, roof drainage, flashing, seams, penetrations, roof edges, substrate preparation, installation conditions, and maintenance awareness. Membrane roofing preparation helps candidates understand roof systems where water management depends on sealed membrane performance rather than steep slope shedding alone.

For concrete and clay tile roofing study, candidates should review tile layout, underlayment, flashing, fastening awareness, slope considerations, roof deck preparation, battens where applicable, hips and ridges, valleys, penetrations, and installation quality. Tile roofing requires attention to weight, layout, weather protection, and manufacturer-style installation practices.

For roofing estimating study, candidates should review roof measurements, squares, waste factors, slope factors, material calculations, labor planning, project sequencing, tear-off awareness, replacement planning, and job cost organization. Estimating knowledge helps candidates connect field work to project planning and business decisions.

For business law study, candidates should review contractor responsibilities, licensing rules, contracts, project management, financial responsibility, safety, risk management, and compliance. The business law portion of licensing is important because licensed contractors are responsible not only for trade work but also for proper business practices and legal compliance.

For application preparation, candidates should keep documents organized, review classification requirements, follow the state application process, and make sure names, business information, and exam records are consistent. The Application Service included with this Ultimate package helps support candidates through that process while they prepare for the exam.

For open book practice, candidates should spend time locating information inside each reference rather than only reading summaries. A useful study method is to take a topic, identify the correct book, locate the section, read the relevant language, and then answer a related practice question. This builds reference speed and helps candidates manage the technical references included in the GS-21 preparation package.

Practice is an important part of this preparation package. Candidates should use the course to identify weak areas, then use the included references to reinforce those topics. Timed practice can help improve confidence for open book testing. Consistent study helps candidates become more comfortable with OSHA safety standards, New Mexico code provisions, IBC and IRC roofing chapters, NRCA roof system guidance, tile roofing installation material, roofing estimating concepts, and business law materials.
