Prepare for the California Roofing (C-39) contractor licensing examinations with a comprehensive Business and Trade package that combines C-39 Trade exam preparation, California Law and Business exam preparation, Application Service, applicable state licensing fees, business setup, and first-year contractor bond cost coverage. This package is designed for candidates pursuing the California C-39 contractor license who want structured roofing exam preparation together with support through the licensing process.
The California C-39 Roofing classification covers contractors who install roofing products and repair surfaces that seal, waterproof, and weatherproof structures. Roofing work is intended to prevent water and other materials from passing through the protective roof system and entering the structure or spaces below.
C-39 work can involve examining and preparing roof surfaces and installing or repairing materials such as asphaltum, pitch, tar, felt, glass fabric, urethane foam, metal roofing systems, flax, shakes, shingles, roof tile, slate, waterproofing materials, weatherproofing products, and membrane roofing systems.
Candidates should prepare for both steep-slope and low-slope roofing work. Important study areas include planning, estimating, tear-off, substrate evaluation, flashings, ventilation, underlayment, membrane systems, shingles, tile, metal roofing, reroofing, roof repairs, fall protection, and general job-site safety.
The C-39 trade examination is divided into Planning and Estimating at approximately 22%, Job Site Preparation for Roof Projects at approximately 13%, Low-Slope Roof Projects at approximately 17%, Steep-Slope Roof Projects at approximately 26%, and Safety at approximately 22%. Steep-Slope Roof Projects is the largest individual section, while Planning and Estimating and Safety are also major portions of the examination.
This package also includes Law and Business exam preparation. Candidates can study California contractor licensing, contracts, business organization, financial management, employment, insurance, liens, public works, and contractor responsibilities while preparing for the technical C-39 examination.
The package further includes Application Service, the application fee, initial license fee, applicable state license fees, business setup, and the first-year cost of the contractor bond required by the state up to $233.
Reference books are not included in this package. The California code books, tile installation manual, NRCA roofing manuals, and Cal/OSHA safety references listed below are study resources that may be obtained separately.
Reference books are not included.
The California Roofing (C-39) trade examination is organized into five major content areas.
Steep-Slope Roof Projects is the largest individual examination section at approximately 26%. Planning and Estimating and Safety each represent approximately 22%, Low-Slope Roof Projects approximately 17%, and Job Site Preparation for Roof Projects approximately 13%.
The C-39 examination uses multiple-choice questions with four answer choices and one best answer. Some questions require mathematical computation, and a calculator is provided during testing. There is no penalty for guessing, so candidates should attempt every question.
Roofing calculations can involve roof area, slope, material quantities, waste, flashing, underlayment, shingles, tile, membrane coverage, fasteners, labor, equipment, and project costs. Candidates should be comfortable converting field dimensions into practical roofing quantities.
The California Roofing (C-39) trade examination is a closed-book examination. Candidates cannot use the California Building Code, California Energy Code, California Residential Code, tile installation manuals, NRCA roofing manuals, Cal/OSHA safety resources, notes, or other study materials during testing.
The California Law and Business examination is also a closed-book examination. Candidates should prepare to recall and apply contractor licensing, contract, financial, employment, insurance, lien, public works, and business-management concepts without relying on outside materials.
Closed-book preparation should focus on understanding roofing systems rather than depending on reference lookup. Candidates should be able to identify proper roof preparation, recognize flashing and underlayment details, distinguish low-slope and steep-slope roofing principles, evaluate common roof problems, and apply appropriate safety practices from memory.
The listed references remain valuable during study because they provide technical guidance for roof assemblies, reroofing, tile installation, membrane systems, metal roofing, flashing, condensation, energy-related roofing issues, and workplace safety.
The California Contractors State License Board administers the C-39 Roofing contractor classification and the associated contractor licensing process.
California defines a C-39 Roofing contractor as a contractor who installs roofing products and repairs surfaces that seal, waterproof, and weatherproof structures. The purpose of this work is to prevent water and other materials from penetrating the protective surface and entering the structure below.
The classification allows roofing contractors to examine and prepare roof surfaces and work with a broad range of roofing and waterproofing materials. These can include shingles, shakes, tile, slate, metal roofing, membranes, urethane foam, felt, asphalt-based products, and other weatherproofing systems.
Roof preparation is a major part of successful roofing work. Contractors may need to evaluate decking, sheathing, substrates, existing roof coverings, flashing, drainage, ventilation, penetrations, and moisture-related damage before installing new roofing materials.
Reroofing projects can require removal of existing materials, correction of damaged substrate, replacement of deteriorated flashing, evaluation of drainage, and coordination of underlayment, ventilation, insulation, and new roof-covering materials.
Low-slope roofing systems depend heavily on continuous waterproofing and effective drainage. Seams, penetrations, edges, terminations, flashings, drains, and substrate conditions can all affect long-term performance.
Steep-slope roofing systems depend on correct sequencing and water-shedding principles. Underlayment, flashing, shingles, tile, metal roofing, ridges, valleys, hips, penetrations, roof edges, and ventilation must work together as part of the completed system.
Safety is especially important in roofing because workers routinely perform tasks at elevation and near open roof edges. Safe ladder use, fall protection, material staging, weather awareness, housekeeping, and controlled access are essential job-site practices.
The package includes the licensing-process items identified for this product: Application Service, application fee, initial license fee, applicable state licensing fees, business setup, and first-year contractor bond cost coverage up to $233.
The following reference books are not included in this package. They are listed as study resources for candidates preparing for the California C-39 Roofing examination.
For Planning and Estimating, candidates should practice evaluating roof dimensions, slope, geometry, penetrations, access, existing conditions, substrate requirements, material needs, labor, and equipment.
Roof measurements are fundamental to estimating. Candidates should understand how length, width, pitch, hips, valleys, ridges, waste, material coverage, and roof configuration affect quantities.
Estimating can involve roofing materials, underlayment, flashing, fasteners, membranes, shingles, tile, metal panels, insulation, adhesives, tear-off, disposal, safety equipment, labor, and project overhead.
Planning should also consider weather conditions, staging areas, access, material delivery, protection of surrounding property, debris control, and coordination with other trades.
For Job Site Preparation for Roof Projects, candidates should focus on protecting surrounding areas, correcting existing roof problems, and removing roofing materials when necessary.
Tear-off can expose the job site to falling debris, nails, sharp materials, dust, unstable walking surfaces, and weather. Work areas should be organized so that workers and surrounding property are protected throughout the process.
Existing roof conditions should be evaluated before new materials are installed. Damaged decking, deteriorated sheathing, moisture problems, failed flashing, poor drainage, uneven surfaces, and inadequate support can affect the finished roofing system.
For Low-Slope Roof Projects, candidates should review membrane systems, flashing, drainage, penetrations, seams, terminations, ventilation, underlayment where applicable, and repairs.
Low-slope systems rely on continuous waterproofing. Small failures around seams, edges, penetrations, drains, or flashing can allow water to enter the assembly.
Drainage is also important. Ponding water and blocked drainage paths can increase stress on roofing materials and contribute to premature deterioration.
Low-slope repairs require careful diagnosis because an interior leak may not be directly below the roof defect. Water can move laterally through insulation, decking, or other portions of the roof assembly before becoming visible.
For Steep-Slope Roof Projects, candidates should study shingles, tile, metal roof systems, underlayment, flashing, ventilation, valleys, hips, ridges, penetrations, and repairs.
Underlayment provides an important secondary layer of protection under many steep-slope roof coverings. Proper installation, overlap, fastening, and detailing around openings and edges can affect overall performance.
Flashing is critical wherever a roof changes direction or intersects another surface. Valleys, chimneys, walls, skylights, plumbing vents, roof edges, and other penetrations require appropriate water-management details.
Tile roofing requires attention to layout, fastening, underlayment, flashing, roof loading, cutting, accessories, and roof geometry. Candidates should understand how the tile, supporting assembly, and water-shedding details work together.
Shingle systems require correct exposure, alignment, fastening, starter materials, underlayment, flashing, ridge treatment, and ventilation. Poor fastening or layout can affect both appearance and weather resistance.
Metal roof systems can involve panels, seams, fasteners, flashings, expansion and contraction, penetrations, edge details, and compatible materials. Candidates should understand why movement and water-shedding details are important.
For Safety, candidates should give special attention to fall protection because roofing work routinely places workers near open edges and on sloped surfaces.
Safe roof access is essential. Ladders should be properly selected, positioned, secured, and used, and workers should understand safe transitions between ladders and roof surfaces.
Material staging can also affect safety. Roofing bundles, tile, tools, and equipment add weight and can create trip or movement hazards. Materials should be positioned with consideration for structural conditions and safe access.
Weather can create additional risks. Rain, dew, wind, heat, and changing surface conditions can affect traction, material handling, equipment operation, and worker exposure.
PPE may include fall-protection equipment, gloves, eye protection, footwear, hearing protection, and respiratory protection depending on the task. Candidates should understand how the hazard determines the appropriate protective equipment.
The Law and Business examination requires dedicated preparation in addition to C-39 technical study. Candidates should review contractor licensing, business organization, contracts, financial management, employment, insurance, liens, public works, payments, and contractor safety responsibilities.
Because both examinations are closed book, candidates should regularly practice applying roofing planning, estimating, low-slope systems, steep-slope systems, flashing, reroofing, repairs, fall protection, and contractor business concepts without relying on the listed references. Reference-based study followed by closed-book practice can help strengthen recall and examination familiarity.
