Nevada Roofing and Siding Contractor (C-15) Exam Book Package

Prepare for the Nevada Roofing and Siding Contractor (C-15) examination with a comprehensive exam book package covering roofing systems, siding installation, construction safety, estimating, carpentry, photovoltaic roof applications, and building-code requirements. This package combines the International Building Code, 2018, which is allowed into the open-book trade examination, with supplemental roofing and siding references used to build technical knowledge before test day.

The Nevada C-15 Roofing and Siding examination is an open-book test. The International Building Code, 2018 is the exam-room-approved reference included in this package. The NRCA roofing manuals, OSHA reference, ASTM siding standard, roofing estimating book, carpentry reference, and photovoltaic roofing guideline are included for study and are not allowed into the trade examination room.

The Nevada C-15 trade examination contains 60 questions, allows 2 hours for completion, and requires 45 correct answers to pass. The examination covers Safety, Roofing Substrates, Steep Roofing, Roofing Repairs, Elastomeric Roofing, Built-up Bituminous Roofing, Sheet Metal and Flashing, Siding, and Photovoltaic Systems.

The C-15 Roofing and Siding classification is broader than the C-15A Roofing subclassification because it encompasses the work authorized under the C-15 roofing and siding subclassifications. Candidates should therefore prepare for both roof systems and exterior wall weatherproofing rather than concentrating only on roof coverings.

Roofing topics include steep-slope systems, membrane roofing, built-up systems, metal panel roofing, spray polyurethane foam roofing, substrates, repairs, flashing, and rooftop photovoltaic considerations. Siding preparation includes materials, installation concepts, soffit applications, weatherproofing, and exterior wall protection.

This package brings those technical areas together so candidates can organize preparation around the major subjects represented on the Nevada C-15 Roofing and Siding Contractor examination.

2. Identify the qualifying individual. The contractor application must identify the person responsible for satisfying the applicable trade qualification requirements.
3. Prepare qualifying experience information. Organize the work-history documentation required for the C-15 classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. After the application and qualification information are reviewed, the qualifying individual can proceed with the required examinations.
6. Prepare for the C-15 trade examination. Study roofing systems, siding, substrates, repairs, safety, flashing, photovoltaic roofing concepts, and building-code requirements.
7. Practice IBC navigation. Use the International Building Code, 2018 throughout preparation so roofing and exterior-wall provisions become familiar.
8. Prepare for Nevada Business and Law. Contractor applicants must satisfy the applicable Nevada business and law requirement unless an authorized waiver applies.
9. Complete the required examinations. Take the applicable trade and business examinations.
10. Complete remaining licensing requirements. Finish the other applicable requirements associated with contractor license issuance.

State Requirements

Nevada recognizes C-15 Roofing and Siding as a specialty contractor classification. A contractor holding the primary C-15 classification may perform the work authorized under the C-15 subclassifications.

The roofing portion covers the installation, application, alteration, and repair of watertight and weatherproof materials used on roofs. Roofing materials can include asphalt, pitch, tar, felt, flax, shakes, shingles, aluminum, tile, slate, urethane, and photovoltaic roof tiles intended to serve in place of other roofing materials.

The siding portion covers the installation, alteration, and repair of siding using materials such as wood, aluminum, enameled steel, plastic, and glass to make exterior walls watertight and weatherproof.

The broader C-15 classification also encompasses insulation and waterproofing work authorized under its subclassifications. This makes the primary C-15 classification more comprehensive than a license limited only to C-15A Roofing or C-15B Siding.

Candidates should understand how roofing, siding, insulation, waterproofing, flashing, substrates, and weather-resistant construction work together as part of the building envelope.

The C-15 trade examination is one component of Nevada contractor licensing. Applicants must also satisfy applicable qualification, application, business and law, financial, and other licensing requirements before a contractor license is issued.

Test Information and Study Materials

A strong C-15 preparation plan should begin with Steep Roofing. Review roof coverings, underlayments, deck conditions, slopes, fastening, valleys, flashing, penetrations, drainage, and roof edges.

Roofing Substrates should include sheathing, structural support, moisture, deterioration, preparation, attachment, and compatibility with the finished roof system.

Siding deserves dedicated study because it is a major difference between the C-15 and C-15A exams. Review wood, metal, plastic, and other siding materials, installation concepts, attachment, expansion and contraction considerations, soffits, flashing, and weather-resistant exterior wall construction.

The ASTM PVC siding and soffit reference can support preparation involving installation methods for rigid PVC products. Candidates should understand the relationship between siding, trim, openings, soffits, exterior wall surfaces, and water management.

Built-up Bituminous Roofing and Elastomeric Roofing should include materials, membrane systems, seams, surfacing, attachment, flashing, penetrations, drainage, and repair conditions.

Metal Panel and SPF Roofing should be reviewed as distinct systems. Candidates should recognize how materials, attachment, joints, insulation, coatings, and installation methods differ from steep-slope shingles or membrane systems.

Roofing Repairs should be studied as a diagnostic subject. Review common leak sources, failed flashing, damaged materials, membrane deterioration, substrate problems, and the relationship between the symptom and the underlying cause.

Sheet Metal and Flashing supports both roofing and siding work. Candidates should understand flashing around valleys, roof-to-wall intersections, penetrations, windows, doors, edges, curbs, and other transition areas where water must be directed away from the building envelope.

Safety is especially important for roofing and siding work because projects can involve ladders, scaffolds, elevated work, power tools, material handling, and fall hazards. OSHA should be used to build safety knowledge that can be recalled independently during the exam.

The International Building Code, 2018 should be used regularly during preparation. Practice finding roofing and exterior-wall provisions using the table of contents and index, then follow related sections, definitions, tables, and exceptions.

Because most books in this package are not allowed into the exam, candidates should gradually move from book-supported study to active recall. Review a technical subject, close the reference, and answer practice questions without immediately looking up the solution.

For the IBC, practice timed navigation instead. Select a topic, identify the likely code location, find the applicable section, and repeat until the process becomes more efficient.

Mixed practice should combine roofing and siding subjects. The examination can move quickly from a steep-slope question to siding, safety, membranes, flashing, estimating, or substrates.

A balanced preparation approach combines technical review, code navigation, recall practice, and timed questions so candidates develop both roofing and siding knowledge rather than relying solely on open-book searching.
