NM GS-21 Roofing Contractor study plan

Map the four exam domains to their percentage weights and rank them by study time so Domain 1 and Domain 2 receive the largest share.

List the roofing systems you actually install (low-slope membrane, steep-slope shingle, tile, metal, coatings) and write a one-paragraph scope statement for each covering components, substrates, and typical failure points.

Build a personal glossary of 30 roofing terms that appear on plans and specs (underlayment, flashing, cricket, drip edge, scupper, parapet, deck, vapor retarder) with a one-line definition and where each is installed.

Locate the New Mexico Construction Industries Division (CID) licensing statute and rule citations for roofing and write down the exact citation numbers you will study from.

Trace the water-shedding path for a low-slope roof from deck to drainage and identify every component that can interrupt it.

Compare at least four steep-slope underlayment and flashing details and explain in writing when each is required versus optional.

Solve 15 practice calculations involving roof area, pitch factor, squares, waste allowance, and material quantity takeoff.

Draft a written sequence of installation steps for one complete roofing assembly you install regularly, from deck inspection through final flashing.

Identify the code provisions that govern roofing, reroofing, and roof drainage and note which edition New Mexico jurisdictions enforce.

Explain in writing how roof deck attachment, edge metal, and flashing details change in high-wind zones and how to verify the requirement for a given address.

List the fire-classification and uplift-resistance ratings that roofing products carry and describe how to document them for an inspector.

Diagnose five common roofing defects (ponding, blisters, ridging, fastener backout, flashing separation) and write the likely cause and the correct repair approach for each.

Outline New Mexico's contractor licensing structure, including the classes or specialties relevant to roofing and what each permits you to bid and perform.

Summarize the licensing application path from qualification through examination and license issuance, listing each document and fee.

State the continuing education and license renewal obligations that apply to New Mexico contractors and note the deadlines.

Describe the complaint, citation, and disciplinary process and the penalties a licensee can face for unlicensed or deficient work.

Explain the rules on subcontracting, qualifying party responsibilities, and supervision requirements for licensed roofing work.

Draft a residential roofing contract that includes scope, exclusions, payment schedule, change-order procedure, warranty terms, and lien-related notices.

Identify the notice and disclosure requirements New Mexico imposes on home improvement and construction contracts and where each must appear in the document.

Describe lien rights, preliminary notice, and the deadlines a roofing contractor must meet to preserve payment claims.

Build a job-costing worksheet that separates labor, material, equipment, overhead, and profit for a roofing project and calculate a break-even price.

Explain employee versus independent contractor classification and the payroll, withholding, and workers' compensation consequences of misclassification.

Summarize hiring, wage, and termination obligations under New Mexico and federal employment law as they apply to a small roofing crew.

Prepare a customer-dispute procedure that documents inspections, change orders, punch lists, and warranty callbacks.

Write a fall-protection plan for a residential reroof covering anchor points, guardrails, warning lines, and rescue procedures.

List the hazard controls for ladder placement, roof access, material hoisting, hot-work with kettles or torches, and electrical clearance.

Describe required personal protective equipment and the training documentation an employer must keep for each worker.

Explain jobsite housekeeping, debris removal, and public-protection measures for occupied buildings and steep-slope work over walkways.

Complete a full-length timed practice exam and score each domain separately to find remaining weak areas.

Re-review every missed item and write a corrected explanation citing the underlying code, rule, or trade principle.

Recite from memory the licensing, contract, lien, and safety deadlines and thresholds most likely to be tested.

Build a one-page final review sheet of formulas, citations, and definitions and confirm exam-day logistics.
