This package is a practical option for candidates who want structured study support without purchasing every rental reference outright. The course helps organize review time, while the books help candidates study roof construction, steep slope systems, membrane roofing systems, tile roof installation, OSHA safety, New Mexico building code requirements, residential and commercial roofing provisions, estimating, and practical field conditions. Together, the materials support a focused path for preparing for the New Mexico GS-21 Roofing Contractor exam.

Exam Details

The New Mexico Roofing Contractor (GS-21) exam is a trade exam for candidates pursuing the GS-21 contractor classification. The exam focuses on roofing trade knowledge, roofing code application, roof safety, steep slope roof systems, membrane roofing systems, tile roof installation, roof construction practices, estimating, materials, flashing, underlayment, roof drainage, New Mexico building code provisions, 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 roofing systems, roof installation practices, code compliance, safety, materials, estimating, and roof assembly performance. Business law preparation supports the administrative, legal, and project-management side of contractor licensing. This package includes both technical rental references and business law materials so candidates can study both sides of the licensing process with a more complete preparation plan.

Important study areas may include OSHA construction safety, fall protection, ladders, scaffolds, personal protective equipment, New Mexico commercial building code requirements, New Mexico residential building code requirements, International Building Code provisions, International Residential Code roof requirements, roof covering materials, roof slope, underlayment, flashing, drainage, roof ventilation awareness, roof deck conditions, fastening, membrane systems, steep slope systems, concrete and clay tile installation, estimating, plan reading awareness, and contractor business law topics.

Because the GS-21 exam is tied to roofing contractor work, preparation should focus on both code knowledge and field application. Candidates should understand how roof systems are selected, installed, fastened, flashed, drained, protected, and inspected. A strong candidate should be able to connect real-world roofing experience with reference-based exam questions and practical job-site judgment.

Open Book Test

The New Mexico GS-21 Roofing Contractor 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, chapter headings, code sections, definitions, tables, figures, diagrams, installation details, safety standards, estimating examples, and roofing manual sections. 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 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 safety standards, New Mexico commercial and residential building code references, IBC and IRC roof provisions, roofing estimating methods, steep slope roofing systems, membrane roofing systems, and concrete and clay tile installation requirements.

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 the type of roofing work being performed. 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 rental references.

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 book and New Mexico business law references included with this package support that part of the licensing process.

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 all names, addresses, business information, and application details consistent throughout the process.

State Requirements

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

Roofing contractor work may involve roof deck evaluation, underlayment installation, flashing, fasteners, roof coverings, tile roofing, membrane roofing, penetrations, edges, valleys, ridges, slopes, drainage, weather protection, safety planning, estimating, and coordination with applicable state and local requirements. Candidates should understand how each part of a roof system supports water shedding, weather resistance, safety, durability, and long-term performance.

The GS-21 classification is a roofing contractor classification and should not be treated as an unlimited building, structural, mechanical, electrical, or general construction classification. 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 roofing contractor work and the contractor responsibilities connected to performing regulated construction work in New Mexico. That includes contractor licensing rules, business obligations, project documentation, code compliance, safety awareness, estimating, inspection readiness, and professional conduct.

Test Information and Study Materials

This rental package supports both technical exam preparation and business law study. The rental books provide the reference foundation for the GS-21 trade exam, while the business law materials support the contractor licensing side of the process. The online course access helps organize study time and gives candidates a structured way to review roofing code topics, OSHA safety, steep slope roofing, membrane roofing, tile roof installation, estimating, New Mexico building code provisions, and business law topics.

A strong GS-21 study routine should begin with the major work areas covered by the classification. Candidates should understand how roof systems are built, how slope affects material selection, how underlayment protects the roof assembly, how flashing controls water movement, how fasteners and attachments support performance, how membrane systems are detailed, how tile systems are installed, and how safety rules apply to roofing work. Exam questions may require both direct reference lookup and practical interpretation of job-site conditions.

For OSHA safety study, candidates should review fall protection, ladders, scaffolds, personal protective equipment, material handling, hazard recognition, walking and working surfaces, access, and safe work practices. Roofing work often involves elevated work areas and weather exposure, making safety preparation an important part of the exam study process.

For building code study, candidates should review New Mexico commercial and residential building code provisions, IBC organization, IRC organization, definitions, roof assemblies, roof coverings, underlayment, flashing, slope, weather protection, fire classification awareness, and residential and commercial roofing requirements. Building code questions often require careful reading because requirements may differ depending on occupancy, structure type, roof material, and roof slope.

For roofing construction and estimating study, candidates should review roof measurements, material quantities, waste factors, takeoffs, roof area calculations, labor awareness, construction methods, roof system planning, and practical field sequencing. Estimating questions may require candidates to understand both math and roofing trade terminology.

For steep slope roofing study, candidates should review roof coverings, underlayment, flashing, valleys, ridges, hips, edges, penetrations, ventilation awareness, weatherproofing details, slopes, and installation best practices. Steep slope systems rely on water shedding, so candidates should understand how each layer and detail supports drainage and protection.

For membrane roofing study, candidates should review membrane types, roof insulation awareness, flashing, roof edges, penetrations, drains, slopes, seams, attachment methods, and weatherproofing details. Membrane systems are often used on low slope roofs, where water control, flashing, and detail work are especially important.

For concrete and clay tile roofing study, candidates should review tile materials, installation methods, battens, fastening, underlayment, flashing, layout, slopes, hips, ridges, valleys, and weather protection. Tile roofing requires careful attention to manufacturer-style installation guidance, support conditions, and proper sequencing.

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.

Practice is an important part of this preparation package. Candidates should use the course to identify weak areas, then use the rental books to reinforce those topics. Timed practice can help improve confidence for open book testing. A helpful study method is to practice finding answers in the books rather than only reading explanations. This builds speed and helps candidates become more comfortable with the references.
