The study references associated with this product include the International Building Code, 2018, NRCA Roofing Manual: Steep Slope Roof Systems, Roofing Construction and Estimating by Daniel Atcheson, 1995, Carpentry and Building Construction, 2016, and Code of Federal Regulations - 29 CFR Part 1926 (OSHA).

Exam Details

The Hawaii Wood Shingles and Wood Shakes Contractor C-42B examination contains 30 questions. Candidates receive 120 minutes to complete the examination, and the minimum passing score is 75%.

The current official examination content outline includes:

• Installation Requirements: 10 questions
• Surface Preparation and Planning: 7 questions
• Roofing Components: 6 questions
• Estimating and Plan Reading: 4 questions
• OSHA Safety: 3 questions

Installation Requirements is the largest category with 10 questions. Candidates should devote substantial study time to wood shingles, wood shakes, installation sequence, exposure, spacing, fastening, underlayment, flashing, weather protection, and related steep-slope roofing practices.

Surface Preparation and Planning accounts for 7 questions. This category can involve evaluating the roof deck, identifying unsuitable conditions, preparing surfaces, organizing materials, planning installation, and coordinating the work before roofing begins.

Roofing Components accounts for 6 questions. Candidates should understand how flashing, valleys, ridges, hips, eaves, rakes, penetrations, underlayment, fasteners, and other components work together to create a watertight roof assembly.

Estimating and Plan Reading contributes 4 questions, while OSHA Safety contributes 3 questions. Because the examination contains only 30 questions, every category can have a significant effect on the final score.

Closed Book Test

This examination is CLOSED book.

The listed technical references are intended for study and are not allowed in the examination center. Candidates should become familiar with roofing terminology, materials, installation methods, flashing, surface preparation, estimating, and safety before exam day.

Closed-book preparation is especially important for a specialized roofing classification. Candidates should be able to recognize correct installation practices without needing to search a manual for every detail.

A useful preparation method is to study a specific topic using the appropriate reference, close the book, and then answer practice questions from memory. After completing the questions, return to the reference and review any mistakes.

The examination allows 120 minutes for 30 questions, which provides an average of approximately 4 minutes per question. This gives candidates time to read carefully, but strong recall is still important for technical and calculation-based questions.

Licensing Steps

1. Confirm that the C-42B classification matches your intended work. Hawaii identifies C-42B as the Wood Shingles and Wood Shakes Contractor classification.
2. Complete the applicable Hawaii contractor license application. Contractor licensing is handled through the Hawaii Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division.
3. Document qualifying experience. Applicants must demonstrate experience that satisfies the Hawaii Contractors License Board requirements for the classification sought.
4. Receive Contractors License Board approval. Applicants must be approved before registering for the contractor examination.
5. Register with PSI after approval. Approved candidates receive information for scheduling the required examination or examinations.
6. Prepare for the C-42B trade examination. Focus on installation requirements, surface preparation, roof components, estimating, plan reading, and OSHA safety.
7. Pass the C-42B examination. The current test contains 30 questions, allows 120 minutes, and requires a 75% passing score.
8. Complete the applicable Business and Law examination. New Hawaii contractor applicants must also satisfy the Business and Law examination requirement when applicable.
9. Complete remaining licensing requirements. All applicable experience, financial, insurance, entity, application, and Board requirements must be satisfied before a contractor license is issued.

State Requirements

Hawaii contractor licensing is regulated by the Contractors License Board under the Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division.

The Hawaii C-42B classification is specifically for contractors who install wood shingles and wood shakes.

The classification includes installation of all flashing materials required to form a watertight surface. Flashing is an important part of roof performance because water commonly enters at transitions, joints, penetrations, valleys, walls, and roof edges when these areas are not properly detailed.

The C-42B scope also includes staining in conjunction with shingle and shake application. Staining performed as part of the roofing installation is therefore included within the classification.

Application of water-repellent materials is also included within the C-42B scope.

Applicants must receive Contractors License Board approval before registering for the examination through PSI. After approval, applicants must pass the required examination or examinations within the applicable six-month examination eligibility period.

Passing the C-42B trade examination alone does not automatically issue a Hawaii contractor license. Applicants must also satisfy Hawaii's applicable experience, Business and Law examination, financial, insurance, application, entity, and other licensing requirements.

Test Information and Study Materials

A strong Hawaii C-42B study plan should begin with Installation Requirements, the largest examination category.

Candidates should understand the practical differences between wood shingles and wood shakes. Although both are wood roof coverings, their appearance, manufacture, thickness, installation characteristics, and detailing can differ.

Study roof slope and how slope affects steep-slope roof performance. Roofing materials depend on gravity and proper overlap to direct water down and away from the structure.

Review exposure, which refers to the portion of a shingle or shake left exposed after the overlapping courses above it are installed. Correct exposure helps create proper coverage and weather protection.

Candidates should also study course layout. Consistent layout supports uniform appearance and helps maintain proper overlaps and coverage throughout the roof.

Spacing is another important concept. Wood roofing materials can respond to changes in moisture, so proper installation practices must account for the characteristics of the material.

Review fastening methods, including fastener placement and the importance of securing each shingle or shake without damaging the material.

Fasteners should work with the roofing material, deck, and exposure conditions. Improper fastening can contribute to splitting, movement, leakage, or premature roof failure.

Underlayment should receive focused study. Underlayment is part of the roof assembly and can provide secondary protection beneath the primary roof covering.

The NRCA Roofing Manual: Steep Slope Roof Systems is especially useful for understanding how shingles, shakes, underlayment, flashing, edges, and other components function together.

Surface Preparation and Planning accounts for 7 questions. Before installing a wood roof covering, the contractor should evaluate the supporting surface and identify conditions that could interfere with installation or performance.

Review roof deck condition, including damaged or unsuitable areas. Roofing installed over an unacceptable surface can inherit problems from the structure beneath it.

Study roof dimensions, slope, penetrations, valleys, transitions, edges, and other features before installation begins. Planning helps determine material requirements and installation sequence.

Moisture should be considered when evaluating wood materials and roof assemblies. Excessive moisture can affect both the supporting structure and the roofing materials.

Material staging is another practical planning consideration. Shingles, shakes, flashing, underlayment, fasteners, and tools should be organized so roofing work can proceed safely and efficiently.

Roofing Components account for 6 questions. Candidates should understand the purpose of each component instead of viewing the roof covering as an isolated layer.

Flashing deserves substantial attention because the C-42B classification specifically includes installation of flashing materials needed to create a watertight surface.

Review flashing at roof-to-wall intersections, penetrations, chimneys, valleys, edges, and other transitions. These locations often require special detailing because ordinary shingle overlap alone may not provide sufficient weather protection.

Valleys collect and direct substantial amounts of water. Proper valley construction is therefore an important part of steep-slope roofing.

Ridges and hips also require specific treatment to protect exposed intersections and complete the finished roof.

Review eaves and rakes. Roof edges must be detailed to protect the assembly and direct water properly.

Roof penetrations such as vents and pipes interrupt the continuous roof covering and therefore require appropriate flashing and integration with surrounding shingles or shakes.

Ventilation can also affect roof assembly performance. Candidates should understand basic roof and attic ventilation concepts as they relate to steep-slope roofing systems.

Estimating and Plan Reading accounts for 4 questions. Candidates should be comfortable reading roof plans, elevations, details, dimensions, and slope information.

Practice calculating roof area. Simple roof surfaces may be calculated as rectangular areas, while more complex roofs may need to be divided into multiple sections before quantities are combined.

Understand the roofing measurement known as a square, which represents 100 square feet of roof area.

Roof slope can affect actual surface area. A sloped roof surface is larger than its horizontal footprint, so candidates should understand how slope relates to material estimating.

Estimating should also consider materials beyond the primary wood covering. Underlayment, flashing, fasteners, ridge and hip materials, and other components may be part of the total project requirements.

Waste and cutting should be considered when planning materials, particularly on roofs with valleys, hips, penetrations, and irregular geometry.

Roofing Construction and Estimating is useful for strengthening measurement, roof geometry, quantities, and practical estimating methods.

Carpentry and Building Construction can reinforce the relationship between the roof covering and the supporting roof structure, including sheathing, framing, slope, dimensions, and construction terminology.

OSHA Safety accounts for 3 questions. The smaller number of questions should not reduce its importance because roofing work involves significant fall and access hazards.

Review fall protection for work near roof edges and other elevated locations. Candidates should understand the importance of recognizing fall hazards and using appropriate protective systems.

Ladder safety is particularly relevant because ladders are commonly used to access roofs. Review selection, setup, placement, access, and safe use.

Scaffold safety may also be relevant when platforms are used to provide access or support roofing operations.

Material handling can create additional hazards. Bundles of roofing material should be handled and positioned with consideration for worker safety, roof loading, and movement on sloped surfaces.

Review safe use of hand and power tools. Roofing work may involve cutting, fastening, drilling, and other operations requiring appropriate tool selection and personal protective equipment.

Weather can affect both roofing quality and worker safety. Wet surfaces can increase slipping hazards, while wind can make handling lightweight roofing materials more difficult.

Use the International Building Code, 2018 during study to reinforce broader requirements for roof assemblies and weather protection.

Use the NRCA Roofing Manual: Steep Slope Roof Systems to strengthen knowledge of wood roofing installation, flashing, underlayment, and component integration.

Because the examination is closed book, gradually reduce dependence on the references as preparation progresses. Study a topic, answer practice questions from memory, and then review the reference afterward.

When a question is missed, identify the underlying category. Determine whether the weakness involved installation, surface preparation, components, estimating, plan reading, or safety.

Since Installation Requirements, Surface Preparation and Planning, and Roofing Components together account for 23 of the 30 questions, these areas should receive the largest share of preparation time.

As examination day approaches, use mixed-topic practice so you become comfortable switching between installation, flashing, planning, estimating, roof components, and OSHA safety.

The included 3 months access provides time to move from individual-topic study into targeted practice, weak-area correction, mixed-question review, and closed-book exam preparation.
