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.
Every tested subject gets the same four layers, in the order that makes the material stick:
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.
Once you’ve worked through every subject, the final phase pulls it all together:
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.
The California C-39 Business & Trade Online Courses package combines two coordinated examination preparation programs:
Package Details: Both online courses are included. Physical and digital reference books, Application Service, state licensing fees, business setup, insurance, and contractor bond services are not included.
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:
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.
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.
California roofing contractors must obtain the appropriate C-39 specialty contractor license through the Contractors State License Board (CSLB).
These courses provide educational preparation for both examinations. Application Service, state licensing fees, business formation, and contractor bonding are separate from this product.
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.
The C-39 roofing trade course is based on the following reference books (not included).
Reference books are not included with this package. The online courses provide organized preparation for their respective closed-book examinations.
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.
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:
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 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 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 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.
At 1 Exam Prep, we combine organized roofing trade instruction with California Law and Business preparation to help students work toward their contractor licensing goals.
Our courses divide roofing project planning, materials, system installation, repair procedures, safety, contractor licensing, business finances, and construction contracts into focused lessons.
Instructor-led videos explain technical concepts and business responsibilities. Reading chapters reinforce understanding, while cram sheets condense important facts, procedures, and regulations for review.
Practice questions with detailed explanations help students apply knowledge, recognize correct responses, and identify subjects requiring additional attention.
Master cram sheets and full-length final examinations provide comprehensive opportunities to review both examination areas.
Because both examinations are closed book, our approach emphasizes comprehension, knowledge retention, and independent application of important technical and business concepts.
Strengthen your roofing expertise, improve your understanding of California contractor business responsibilities, and prepare for both licensing examinations with 1 Exam Prep.
