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 Ultimate Business & Trade Courses & Application Package. This comprehensive package combines California C-39 Roofing Trade Exam preparation, California Law and Business Exam preparation, and Application Service to help you pursue your contractor licensing goals.
With 1 year of course access, you can study roofing materials, estimating, low-slope and steep-slope installations, job site preparation, repairs, fall protection, and California contractor business requirements through organized online instruction.
Whether your experience involves residential shingles, commercial membranes, metal roofing, tile, or reroofing projects, this package helps turn practical trade experience into focused examination preparation while providing assistance with your California Contractors State License Board (CSLB) application paperwork.
Every tested subject gets the same four layers, in the order that makes the material stick:
Each layer reinforces what you learned in the previous lesson. Videos introduce roofing and business concepts, reading chapters strengthen understanding, cram sheets highlight essential information, and practice questions help you apply your knowledge.
This method organizes roof measurements, installation procedures, material selection, fall protection, licensing regulations, and construction contracts 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 method designed to help you retain knowledge, identify difficult subjects, and prepare confidently for your first examination attempt.
California C-39 Roofing Examination Preparation and Licensing Application Support
Package Details: Both online courses, 1 year of course access, and Application Service are included. Reference books, state licensing fees, business setup, insurance, and contractor bond costs are not included.
The California Roofing (C-39) Contractor Examination evaluates planning, estimating, job site preparation, low-slope and steep-slope roofing, repairs, and safety.
The official CSLB C-39 examination study guide, applicable to examinations scheduled on or after January 1, 2023, identifies five categories:
These percentages are approximate. Steep-Slope Roof Projects is the largest category at 26%, followed by Planning and Estimating and Safety at 22% each.
The examination uses multiple-choice questions with four possible answers 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 Trade Course follows these examination categories so students can concentrate on the roofing subjects relevant to their test.
Both the California C-39 Roofing Trade Examination and California Law and Business Examination are closed book. Candidates cannot use roofing manuals, building codes, reference books, notes, or other study materials during testing.
For the roofing examination, students must understand estimating, preparation, roofing materials, installation procedures, repairs, and fall protection independently.
The Law and Business examination requires knowledge of licensing, contracts, financial management, employment responsibilities, insurance, and safety.
Our four-layer method emphasizes understanding instead of relying on reference books during testing. Master cram sheets and full-length final examinations help students review important information and recognize subjects requiring additional attention.
California roofing contractors must obtain the appropriate C-39 specialty contractor license through the Contractors State License Board.
The included Application Service supports paperwork preparation and organization. CSLB determines eligibility, examination requirements, application acceptance, and license issuance.
California regulates roofing contractors through the CSLB under the C-39 Roofing specialty classification.
The classification covers qualifying roofing installation and repair work involving systems and materials used to seal, waterproof, and weatherproof buildings.
Roofing projects may involve asphalt roofing, shingles, tile, slate, metal roofing, membranes, wood shakes, and spray polyurethane foam systems.
Applicants must satisfy applicable experience, application, examination, and license issuance requirements. Licensed contractors must comply with applicable building codes, energy requirements, construction safety regulations, insurance, and bonding obligations.
Roofing contractors must also understand safe work practices for elevated surfaces, ladders, scaffolding, equipment, and changing weather conditions. Fall protection is a particularly important responsibility.
The C-39 roofing trade course is based on the following reference books (not included).
Reference books are not included with this Ultimate Package. The online courses provide organized preparation for the two closed-book examinations.
Effective C-39 preparation requires understanding roofing project planning, material selection, job site preparation, roof system installation, repairs, and safety.
Planning and Estimating: Review roof measurements, materials, project specifications, quantities, labor, and equipment needs.
Job Site Preparation: Study protecting surrounding property, correcting existing roofing problems, inspecting roof conditions, and tear-off procedures.
Low-Slope Roofing: Understand roof membranes, flashing, underlayment, installation procedures, and repairs.
Steep-Slope Roofing: Review shingles, tile, metal roofing, roof ventilation, flashing, underlayment, and repair techniques.
Safety: Focus on fall protection, personal protective equipment, ladders, scaffolding, and job site hazards.
Videos explain these concepts, reading chapters reinforce technical understanding, and cram sheets condense essential information. Practice questions and final examinations help students apply their knowledge.
The California Law and Business Exam Prep Online Course is included with this Ultimate Package.
Roofing contractors must understand business responsibilities alongside technical trade knowledge. Operating a contracting business involves licensing, financial management, employment requirements, insurance, contracts, and workplace safety.
The CSLB Law and Business examination study guide identifies seven major categories:
Contract Requirements and Execution is the largest approximate category at 21%, followed by Employment Requirements at 20%.
The Law and Business examination is also multiple choice and closed book. The included course follows the same four-layer study structure as the C-39 Roofing Trade Course.
An important benefit of this Ultimate Package is Application Service.
Applying for a California C-39 contractor license involves preparing CSLB paperwork, documenting qualifying roofing experience, and organizing required application information.
Application Service provides assistance preparing and organizing contractor license application materials, helping customers address administrative steps alongside examination preparation.
This service complements both online courses by combining trade and business education with practical licensing application support.
CSLB determines application acceptance, examination eligibility, and license issuance. Application Service assists with documentation and does not replace state licensing requirements.
Roofing projects begin with evaluating site conditions, reviewing plans, selecting suitable materials, and estimating project requirements.
Contractors must understand roof measurements, slope, material quantities, equipment, labor, and installation considerations.
Job site preparation also involves protecting surrounding property, inspecting existing surfaces, identifying problems, and removing unsuitable roofing materials.
These activities influence installation quality, safety, and project planning. Our C-39 course reinforces these subjects through focused instruction and examination-style practice.
Low-slope roofing systems often involve membranes, flashing, insulation, drainage considerations, and specialized application methods.
Steep-slope roofing systems may involve shingles, concrete or clay tile, wood shakes, slate, and metal roof coverings.
Both types require understanding underlayment, flashing, ventilation, installation details, and appropriate repair procedures.
Steep-Slope Roof Projects account for approximately 26% of the C-39 examination, making them an important focus for preparation.
Our course helps students connect roofing material characteristics with system installation and maintenance principles.
Roofing work frequently involves elevated surfaces, ladders, scaffolding, powered equipment, and material handling.
Contractors must understand fall protection, safe roof access, personal protective equipment, and appropriate job site precautions.
Hazards may also involve roof openings, changing weather conditions, electrical equipment, and nearby overhead lines.
Safety represents approximately 22% of the C-39 examination. Our lessons reinforce personnel protection, job site safety, and fall prevention through focused review and practice questions.
At 1 Exam Prep, we combine roofing trade instruction, California Law and Business preparation, and Application Service to support your contractor licensing goals.
Our courses divide estimating, roofing materials, low-slope and steep-slope installations, repairs, fall protection, contracts, and business responsibilities into focused lessons.
Instructor-led videos explain technical concepts. Reading chapters reinforce understanding, while cram sheets summarize essential information for convenient review.
Practice questions with detailed explanations help students apply knowledge and identify subjects requiring additional attention.
Master cram sheets and full-length final examinations provide opportunities to assess preparation across both examination areas.
With 1 year of course access, students can revisit challenging lessons, repeat practice activities, and maintain consistent study habits.
