California Roofing (C-39) Contractor Licensing Exam Prep Business & Trade Online Courses

Master Every Tested Subject. Pass the First Time.

California contractor exams are closed book, so the only thing walking into that testing center with you is what you’ve learned. Our California courses are built from the ground up for that reality — organized subject by subject around the official CSLB test plan, so every minute you study is aimed at what’s actually on the exam.

Prepare for your California Roofing (C-39) Contractor License with 1 Exam Prep's Business & Trade Online Courses. This comprehensive examination preparation package combines the California C-39 Roofing Trade Exam Prep Online Course and the California Law and Business Exam Prep Online Course, helping students prepare for both examinations associated with California contractor licensing.

Roofing contractors need specialized knowledge of roofing materials, project estimating, roof preparation, low-slope systems, steep-slope systems, waterproofing, repairs, and fall protection. California contractor applicants also need to understand licensing regulations, financial management, construction contracts, employment responsibilities, insurance, and workplace safety.

Our online courses bring these important subjects together through structured instruction, focused reading chapters, cram sheets, practice questions, and comprehensive final examinations. Whether your experience involves residential roofing, commercial roofing, roof repairs, tile, shingles, or membrane systems, this package helps you prepare for both examinations through organized, trade-focused study.

Our Proven 4-Layer Study Method

Every tested subject gets the same four layers, in the order that makes the material stick:

  1. Subject Video — A focused, instructor-led lesson that walks you through the concepts, the terminology, and the traps the exam likes to set.
  2. Reading Chapter — A brief, plain-English (or Spanish) chapter that reinforces the video. No 400-page codebook to wade through — just what you need to know, explained clearly.
  3. Cram Sheet — The key facts, figures, and rules for that subject condensed onto a tight memory sheet you can review anywhere.
  4. Practice Questions — Exam-style questions for that subject, each with a full answer explanation, so you know not just what the right answer is but why.

Each layer builds on the previous lesson. Videos introduce technical roofing or business concepts, reading chapters reinforce understanding, cram sheets highlight information worth remembering, and practice questions help students apply what they have learned.

This consistent method makes it easier to organize roofing calculations, installation procedures, material selection, construction contracts, and safety requirements into manageable study sessions.

Then Lock It In

Once you’ve worked through every subject, the final phase pulls it all together:

  • Master Cram Sheets — Every subject’s cram sheet consolidated into one review set you can run through in the days before your exam.
  • Full-Length Final Exams — Unique practice finals built to mirror the real exam’s structure and subject weighting. Take them as many times as you need to walk in confident.

Learn it. Reinforce it. Condense it. Test it. Then prove it on a full-length final — a structured preparation method designed to strengthen knowledge retention, identify difficult subjects, and help students approach their first examination attempt with confidence.

Exam Details

The California Roofing (C-39) Contractor Examination evaluates knowledge of project planning, estimating, roof preparation, roofing installation, repairs, and safety.

The official CSLB C-39 examination study guide for examinations scheduled on or after January 1, 2023, identifies five major examination categories:

  • Planning and Estimating — 22%: Planning roofing projects, understanding project requirements, and estimating roofing work.
  • Job Site Preparation for Roof Projects — 13%: Protecting surrounding areas, correcting existing problems, and removing roofing materials during tear-off.
  • Low-Slope Roof Projects — 17%: Installing flashing, ventilation, and underlayment; installing low-slope roof systems; and repairing existing roofs.
  • Steep-Slope Roof Projects — 26%: Installing flashing, ventilation, and underlayment; installing steep-slope roof systems; and performing repairs.
  • Safety — 22%: Personnel protection, job site safety, and fall protection.

These percentages represent approximate examination weighting. Steep-Slope Roof Projects is the largest category at 26%, followed by Planning and Estimating and Safety at 22% each.

The roofing examination uses multiple-choice questions with four answer choices and one best answer. Some questions require mathematical calculations, and a calculator is provided during testing. There is no penalty for guessing.

Our C-39 Roofing Trade Course organizes preparation around these categories to help students concentrate on the technical subjects relevant to the examination.

Closed Book Test

Both the California C-39 Roofing Trade Examination and California Law and Business Examination are closed book. Roofing manuals, building codes, reference books, notes, and other study materials cannot be used during testing.

Roofing candidates must understand project estimating, installation procedures, material selection, flashing, waterproofing, repair methods, and safety without consulting technical references.

The Law and Business examination requires independent knowledge of contractor licensing, contracts, finances, employment requirements, insurance, and safety obligations.

Our four-layer study method reinforces these subjects through instruction, reading, cram sheets, and examination-style questions. Full-length final examinations help students evaluate their understanding and identify subjects requiring additional preparation.

Licensing Steps

California roofing contractors must obtain the appropriate C-39 specialty contractor license through the Contractors State License Board (CSLB).

  1. Confirm Your Classification: Determine whether C-39 covers the roofing installation, weatherproofing, waterproofing, and repair services your business intends to offer.
  2. Review Experience Requirements: Evaluate qualifying roofing construction experience and applicable CSLB qualifications.
  3. Prepare Your Application: Complete the appropriate contractor license application and organize supporting documents.
  4. Submit Application Materials: Provide required experience information, application documents, and applicable state fees.
  5. Prepare for Both Examinations: Study C-39 Roofing Trade subjects and California Law and Business using the included online courses.
  6. Complete Required Testing: Follow CSLB scheduling instructions and satisfy applicable examination requirements.
  7. Meet License Issuance Requirements: Complete applicable bonding, insurance, fees, and remaining licensing obligations.

These courses provide educational preparation for both examinations. Application Service, state licensing fees, business formation, and contractor bonding are separate from this product.

State Requirements

The California Contractors State License Board regulates roofing contractors under the C-39 Roofing specialty classification.

California Code of Regulations, Title 16, Section 832.39 describes work involving roofing materials and surfaces used to seal, waterproof, and weatherproof structures.

C-39 work may involve asphalt roofing, roof membranes, metal, wood shakes, shingles, tile, slate, spray polyurethane foam, and other qualifying roofing materials.

Applicants must satisfy applicable CSLB experience, examination, application, and license issuance requirements. Licensed roofing contractors must also comply with relevant building codes, energy regulations, construction safety requirements, and insurance obligations.

Roofing projects frequently involve elevated work, ladders, scaffolding, fall hazards, equipment, and weather exposure. Appropriate job site planning and fall protection are essential responsibilities for roofing professionals.

Test Information and Study Materials

Effective California C-39 preparation requires understanding roofing project planning, roof system components, installation methods, repair procedures, and safety.

Planning and Estimating: Review roof measurements, material quantities, labor requirements, project specifications, and equipment needs.

Job Site Preparation: Study surrounding-property protection, roof inspections, correcting existing problems, material removal, and tear-off procedures.

Low-Slope Roofing: Understand roof membranes, flashing, ventilation, underlayment, system installation, and repairs.

Steep-Slope Roofing: Review shingles, tile, metal roofing, roof assembly components, installation details, and repair methods.

Safety: Focus on personnel protection, fall protection, ladders, scaffolding, and job site hazards.

Instructor-led videos explain these topics, reading chapters reinforce technical knowledge, and cram sheets summarize essential information. Practice questions and full-length final examinations help students apply their knowledge across the examination categories.

California Law and Business Exam Preparation Included

The California Law and Business Exam Prep Online Course is included with this package.

Roofing contractors need business knowledge alongside technical trade expertise. Operating a contracting company involves licensing, financial management, employment obligations, contracts, insurance, and safety responsibilities.

The official CSLB Law and Business examination study guide for examinations scheduled on or after December 1, 2021, identifies seven major categories:

  • Business Organization and Licensing — 13%: Company organization, licensing requirements, advertising, and subcontracting.
  • Business Finances — 15%: Cash management, budgeting, taxes, and financial reporting.
  • Employment Requirements — 20%: Hiring employees, supervision, training, records, and payroll.
  • Insurance and Liens — 12%: Workers' compensation, business insurance, liens, and related remedies.
  • Contract Requirements and Execution — 21%: Bidding, cost control, project organization, construction contracts, and payments.
  • Public Works — 5%: Prevailing wage, bonding, and insurance requirements.
  • Safety — 14%: Training, reporting, general workplace safety, and hazardous materials.

Contract Requirements and Execution is the largest Law and Business category at approximately 21%, followed by Employment Requirements at 20%.

The Law and Business examination is multiple choice and closed book. The included course follows the same four-layer study method as C-39 roofing preparation, creating a consistent approach to reviewing both examination areas.

Roofing Project Planning and Estimating

Roofing projects begin with evaluating existing conditions, reviewing specifications, identifying suitable materials, and determining project requirements.

Contractors need to understand roof dimensions, slope, material quantities, equipment, labor, and installation considerations.

Different roofing systems can affect material selection, work sequencing, and installation procedures. Proper planning also requires recognizing job site conditions and protecting the surrounding property.

Our C-39 course reinforces these concepts through focused explanations and practice questions designed to develop greater familiarity with roofing project decisions.

Low-Slope and Steep-Slope Roofing Systems

Low-slope roofing systems often involve membranes, insulation, flashing, drainage details, and specialized installation procedures.

Contractors must understand how roofing materials work together to protect buildings from moisture and weather exposure.

Steep-slope systems may involve shingles, tile, metal, wood shakes, and other approved roof coverings. Installation includes underlayment, flashing, ventilation, fastening, and related system components.

Repair work requires evaluating existing materials, recognizing damaged areas, and understanding appropriate procedures for restoring roof protection.

Because Steep-Slope Roof Projects represents approximately 26% of the C-39 examination, this category deserves careful review alongside low-slope roofing principles.

Roof Tear-Off, Reroofing, and Job Site Safety

Roof preparation requires protecting surrounding areas, examining existing conditions, removing roofing materials, and addressing problems before installing a new system.

Reroofing projects introduce considerations involving existing assemblies, material compatibility, preparation, and appropriate installation practices.

Roofing safety is equally important. Elevated work introduces fall hazards, ladder and scaffold risks, and challenges involving tools and material handling.

Contractors must understand personnel protection, safe job site organization, and applicable fall protection principles.

Safety accounts for approximately 22% of the C-39 examination. Our study materials reinforce these responsibilities through focused lessons and examination-style practice questions.
