Ready to become a licensed Nevada Roofing and Siding Contractor? This comprehensive guide explains Nevada C-15 licensing requirements, PSI examination details, the official study categories, roofing and siding installation concepts, safety, waterproofing, business and law preparation, and related books from Contractor Exam Preps.
Roofing and siding contractors play an important role in protecting buildings from weather, moisture, and everyday wear.
In Nevada, contractors work on residential homes, apartment buildings, retail centers, office buildings, industrial properties, and other structures.
Even though Nevada has plenty of sunshine, roofs and exterior walls still face demanding conditions.
High temperatures, ultraviolet exposure, wind, occasional heavy rain, and temperature changes can all affect building materials.
When a roof leaks, nobody wants to hear that the contractor thought flashing was merely decorative trim!
Good roofing and siding work requires understanding the entire building envelope.
The roof deck, underlayment, roof covering, penetrations, flashings, drainage, exterior walls, siding, and weather barriers must work together.
Contractors must understand proper installation, repairs, material compatibility, construction safety, and applicable building-code requirements.
The Nevada C-15 examination measures knowledge across many of these subjects.
C-15 Roofing and Siding is a Nevada specialty contractor classification issued by the Nevada State Contractors Board.
It covers work authorized under the C-15 roofing and siding subclassifications, including applicable insulation and waterproofing work.
The classification includes installation, alteration, application, and repair of roofing materials used to make buildings watertight and weatherproof.
It also covers appropriate siding installation, alteration, and repair to protect exterior walls.
Roofing materials can include shingles, shakes, tile, slate, metal, and other approved roof systems.
Siding materials may include wood, metal, plastic, and other recognized exterior wall coverings.
The exact legal scope is governed by Nevada's contractor classification rules.
The primary C-15 classification is broader than the C-15A Roofing subclassification.
C-15A focuses on roofing work.
C-15 includes roofing and siding along with other work covered by its related subclassifications.
The distinction is important for examination preparation.
A candidate studying only shingles and roof repairs may overlook siding questions, exterior wall weatherproofing, flashing, and photovoltaic roof components.
The full C-15 trade examination includes those subjects.
The Nevada State Contractors Board administers contractor licensing in Nevada.
The Board reviews applications, qualifications, work experience, financial responsibility, and other licensing requirements.
It determines whether applicants are eligible to take the required examinations.
After approval, candidates receive examination eligibility instructions.
PSI administers the C-15 Roofing and Siding trade examination.
Applicants also generally must satisfy the Nevada Contractor Management Survey examination, also known as the CMS business and law exam.
Both the trade and business components are part of the broader licensing process, subject to applicable exemptions or waivers.
The Nevada C-15 Roofing and Siding Contractor trade examination contains 60 scored questions.
Candidates have two hours, or 120 minutes, to complete the examination.
The passing requirement is 45 correct answers.
That equals a 75% passing score.
On average, candidates have two minutes per scored question.
Some questions can be answered quickly from trade experience.
Others may require looking up information in the approved building code reference.
PSI may include additional unscored experimental questions, depending on the current examination bulletin.
Candidates should answer every question carefully because experimental questions are not identified during the examination.
Yes. The C-15 trade examination is open book, but it has specific reference restrictions.
The current listed exam-room reference is the 2018 International Building Code.
Roofing manuals, OSHA books, construction estimating texts, siding installation standards, and photovoltaic roofing publications are study references.
They are not automatically permitted inside the C-15 trade examination room.
This distinction matters.
The Nevada C-15 Roofing and Siding Exam Book Package contains both the approved 2018 IBC and supplemental technical roofing and siding books.
Candidates should practice using the IBC to locate relevant code provisions and use the other publications to develop knowledge before test day.
The current C-15 examination outline includes nine technical categories.
The nine categories total 60 scored questions.
Steep Roofing is the largest examination category, with 16 questions.
Roofing Substrates and Siding each contain eight questions.
Elastomeric Roofing and Built-Up Bituminous Roofing contain seven questions each.
That means candidates should understand both steep-slope and low-slope roof systems.
Steep-slope roofing is the largest subject on the exam.
Students should review asphalt shingles, wood shakes, wood shingles, tile, slate, metal roof coverings, underlayments, fastening, roof decks, and installation practices.
Study roof edges, ridges, hips, valleys, penetrations, and roof transitions.
Understand the purpose of flashing and how roofing components move water away from the structure.
Review manufacturer instructions and applicable code provisions.
The Roofing Construction and Estimating book offers useful study on steep roofing, roofing materials, installation, and project estimating.
The roof substrate supports the roofing assembly.
A roof covering cannot perform properly if the underlying surface is damaged, unstable, or unsuitable.
Candidates should review roof sheathing, deck materials, moisture problems, substrate deterioration, attachment, and preparation.
Learn to recognize conditions that require repair before installing a new roof system.
Study the relationship between roof slope, substrate condition, drainage, and roofing material compatibility.
Roof substrates account for eight questions on the current C-15 blueprint.
Low-slope commercial roofs often use membrane or coating systems rather than conventional shingles.
Students should study elastomeric roofing systems, membrane performance, seams, attachment, waterproofing, and roof drainage.
Know why the correct application method and substrate preparation matter.
Review common causes of leaks and system failures.
Understand how flashing connects the membrane to roof edges, penetrations, and adjacent construction.
Built-up roofing uses multiple layers of roofing materials designed to create a weather-resistant roof system.
Students should understand asphaltic materials, reinforcing plies, surfacing, installation practices, and repairs.
Review how low-slope roof design influences drainage and waterproofing.
Learn to identify common installation problems and maintenance requirements.
The C-15 exam includes seven questions in the Built-Up Bituminous Roofing category.
Roof repair questions may involve identifying damage, choosing repair methods, and recognizing the cause of water intrusion.
Students should understand aging roofing materials, punctures, failed flashing, damaged shingles, membrane defects, and drainage problems.
A leak inside a building does not always mean that the water entered directly above the stain.
Water can travel along roof components before becoming visible.
Good troubleshooting requires examining the complete roof assembly.
Siding is a major part of the Nevada C-15 examination.
The current outline contains eight siding questions.
Students should study the installation of wood, metal, plastic, and related exterior siding materials.
Review fasteners, joints, trim, corners, soffits, and transitions.
Understand the importance of water-resistive barriers, flashing, and weatherproofing.
Exterior wall coverings must work with windows, doors, roof edges, and other building-envelope components.
The ASTM D4756 standard is a useful technical study reference for rigid PVC siding and soffit installation.
It is included in the Nevada C-15 technical book package for study but is not listed as an allowed trade-exam-room reference.
Sheet metal and flashing help direct water away from vulnerable areas.
Students should review step flashing, counterflashing, valley flashing, roof edges, drip edges, and penetration details.
Study how metal components connect roof coverings and exterior wall materials.
Learn why poor flashing can cause leaks even when the main roofing material is installed correctly.
The C-15 examination includes three questions specifically assigned to Sheet Metal and Flashing.
Modern roofs may include solar panels, mounting systems, or photovoltaic roof tiles.
The current C-15 examination includes two questions about Photovoltaic Systems.
Roofing contractors should understand how rooftop solar equipment can affect weatherproofing, penetrations, mounting, flashing, and maintenance access.
Photovoltaic roofing work may also require coordination with appropriately licensed electrical or solar contractors.
A roofing contractor should not assume that C-15 automatically authorizes separate electrical installations.
Roofing work involves significant fall and jobsite hazards.
Safety is one of the official examination categories.
Students should review fall protection, ladders, scaffolds, personal protective equipment, tools, material handling, and hazard recognition.
Study OSHA construction safety principles, including applicable fall-protection requirements.
High temperatures and sun exposure are also important practical concerns for Nevada roofers.
Work planning should account for weather, heat, worker safety, and safe roof access.
Roofing contractors must estimate materials accurately.
Study roof area, slope, waste factors, underlayment quantities, flashing lengths, fasteners, labor, and demolition costs.
A roofing square equals 100 square feet of roof area.
However, the actual surface area of a sloped roof may be larger than the horizontal footprint.
Estimating also must consider waste, special materials, roof penetrations, difficult access, and disposal.
The Roofing Construction and Estimating reference provides examples and methods for roofing takeoffs and estimates.
The Nevada State Contractors Board generally requires a trade qualifying individual with four years of qualifying experience within the previous 15 years.
Acceptable experience may include journeyman, foreman, supervising employee, or contractor work within the requested classification.
The Board may accept qualifying education or training toward a portion of the experience requirement under its rules.
Applicants should review the current contractor application for documentation requirements and any applicable exceptions.
Experience must be relevant to C-15 Roofing and Siding, not merely general construction work.
The Nevada State Contractors Board currently lists a $300 application processing fee.
The Board also lists a $600 biennial license fee after approval.
Applicants must meet applicable financial responsibility requirements.
Contractor license bonds are set individually by the Board.
The Board's published general bond range is $1,000 to $500,000, depending on the applicant's circumstances.
That does not mean every C-15 contractor must post the same bond.
The required amount is communicated during the licensing process.
Workers' compensation compliance or an appropriate exemption may also be required.
Start with the official PSI C-15 examination outline.
Confirm the approved 2018 International Building Code reference.
Study steep roofing, roofing substrates, siding, elastomeric roofing, built-up roofing, repairs, flashing, photovoltaic components, and safety.
Review the applicable roofing manuals and estimating books as technical study references.
Practice locating roofing and exterior wall provisions in the IBC.
Complete timed practice questions using the 60-question, two-hour examination format.
Review missed questions and repeat your weakest categories.
Study the Nevada CMS business and law requirements separately.
With a clear plan and suitable references, preparing for C-15 can be much more manageable.

After Examination and Board Review
This schedule follows the official trade-examination subjects and includes preparation for the separate business and law examination.
The Nevada C-15 examination can be challenging because it covers several different roofing systems and exterior siding work.
Someone experienced in asphalt shingles may know steep roofing very well.
However, the examination also includes elastomeric roofing, built-up bituminous systems, siding, flashing, repairs, substrates, safety, and photovoltaic systems.
The examination contains 60 scored questions, and candidates have two hours.
They must answer 45 questions correctly.
Because only the listed 2018 IBC may be used as the trade reference, candidates must learn much of the technical content before testing.
Steep Roofing accounts for 16 questions.
Roofing Substrates and Siding each contribute eight.
Low-slope roofing subjects also make up a significant part of the examination.
Consistent study and mixed practice help candidates prepare.
The Nevada C-15 Exam Book Package covers the major technical subjects.

Preparing for the Nevada C-15 Roofing and Siding Contractor examination is an important step for construction professionals who want to become licensed in this specialty trade.
Roofs and exterior walls protect buildings from weather and moisture.
When these systems are installed correctly, they support the long-term performance of homes, commercial buildings, offices, warehouses, and other structures.
When roofing or siding systems fail, the consequences can include leaks, damaged materials, and expensive repairs.
That is why contractors need to understand proper materials, installation methods, building codes, and safety requirements.
Nevada's C-15 Roofing and Siding classification is administered by the Nevada State Contractors Board.
The classification covers roofing and siding work and authorized related work under its subclassifications.
It is broader than the narrower C-15A Roofing subclassification.
Applicants should understand which classification matches their intended business activities.
The Nevada C-15 trade examination is administered through PSI.
It contains 60 scored questions.
Candidates have two hours to complete the test.
The passing requirement is 45 correct answers, equivalent to 75%.
The examination is open book, but it has strict reference limits.
The listed exam-room trade reference is the 2018 International Building Code.
Other roofing manuals, siding standards, OSHA publications, estimating books, and photovoltaic references are valuable study tools but are not approved C-15 trade-exam-room books.
Students should learn to use the 2018 IBC effectively.
Practice locating roofing provisions, exterior wall requirements, construction definitions, tables, and exceptions.
Good reference navigation can help save time during the examination.
The current C-15 examination outline contains nine major technical categories.
Steep Roofing is the largest subject, with 16 questions.
Roofing Substrates and Siding each contain eight questions.
Elastomeric Roofing and Built-Up Bituminous Roofing each contain seven.
The remaining questions cover Safety, Roofing Repairs, Sheet Metal and Flashing, and Photovoltaic Systems.
These categories show that C-15 candidates need broad roofing and exterior wall knowledge.
Studying only asphalt shingles is not enough.
Students should review tile, slate, wood shingles, wood shakes, metal roofing, roof underlayments, fastening, and drainage.
They should also understand roof decks and substrates.
A roof covering depends on the supporting surface.
Damaged decking, moisture problems, poor attachment, or incorrect preparation can create problems throughout the roofing assembly.
Low-slope roofing is another important study area.
Candidates need to understand elastomeric roofing, built-up bituminous systems, membranes, seams, coatings, surfacing, and repairs.
Roofing systems must move water effectively while protecting vulnerable areas.
Flashing is particularly important at valleys, edges, penetrations, and roof-to-wall transitions.
Siding also deserves dedicated study time.
Exterior wall systems use materials such as wood, metal, and plastic.
Installation details may involve fasteners, corners, joints, trim, soffits, and weather-resistant barriers.
Understanding how siding connects with roofing and flashing helps candidates recognize proper building-envelope construction.
Photovoltaic roofing is included in the examination.
Contractors should understand roof penetrations, mounting, waterproofing, and coordination with other licensed trades.
Safety is another required examination subject.
Roofing involves fall hazards, ladders, scaffolds, power tools, and other jobsite risks.
Students should understand appropriate safety practices and recognize unsafe working conditions.
Roofing estimating is valuable for business operations.
Contractors must measure roof areas, estimate materials, account for waste, evaluate labor, and understand project costs.
Accurate estimates help reduce costly mistakes and support professional contracting.
The Nevada contractor license application includes additional requirements beyond passing the trade examination.
The Nevada State Contractors Board generally requires a trade qualifying individual with four years of relevant experience within the preceding 15 years.
Applicants must also complete the contractor application and applicable business and law examination.
The Board currently lists a $300 application processing fee and a $600 biennial license fee.
Financial responsibility, contractor bonding, and workers' compensation requirements may also apply.
The license is issued only after all applicable conditions have been satisfied.

Nevada C-15 Roofing and Siding Contractor Exam Prep helps contractor applicants understand the trade examination, licensing requirements, and technical knowledge needed for Nevada's Roofing and Siding specialty classification.
The Nevada State Contractors Board administers the C-15 license. This classification covers roofing, siding, and related work authorized within the classification's scope. It is broader than the C-15A Roofing subclassification because it includes additional exterior wall and related work.
Roofing and siding contractors install, alter, repair, and maintain systems that protect buildings from weather and moisture. Their work may involve roof coverings, underlayments, decks, membranes, flashing, siding, soffits, fascia, waterproofing, and related components.
Applicants for Nevada C-15 licensing must satisfy the Board's qualification requirements. The trade qualifying individual generally needs four years of relevant work experience within the 15 years preceding the application. The Board may recognize qualifying education or training under its rules.
The Nevada contractor application includes an application processing fee, proof of qualifications, financial responsibility documents, and other required information. The Board currently lists a $300 application fee and a $600 biennial license fee. The required contractor license bond is determined by the Board for the applicant.
Contractor applicants generally must complete a trade examination and the separate Contractor Management Survey business and law examination. PSI administers the required examinations after the Nevada State Contractors Board determines examination eligibility.
The Nevada C-15 Roofing and Siding trade examination contains 60 scored questions. Candidates have two hours to complete the test. The minimum passing requirement is 45 correct answers, which equals 75%.
The examination is open book, but the permitted reference list is limited. The 2018 International Building Code is the listed exam-room-approved trade reference. Candidates should confirm the current PSI rules before testing.
The C-15 examination covers nine technical categories. Steep Roofing is the largest, with 16 questions. Roofing Substrates and Siding each have eight questions. Elastomeric Roofing and Built-Up Bituminous Roofing each have seven. Safety, Roofing Repairs, Sheet Metal and Flashing, and Photovoltaic Systems make up the remaining questions.
Steep roofing preparation includes asphalt shingles, wood shingles, shakes, tile, slate, metal roofing, underlayments, roof slopes, fasteners, valleys, hips, ridges, and flashing.
Roofing substrate study involves roof decks, sheathing, structural support, moisture conditions, deterioration, repairs, and preparation. Understanding the supporting roof assembly is important because the performance of roofing materials depends on what is installed beneath them.
Low-slope roofing topics include elastomeric systems and built-up bituminous roofing. Candidates should understand membranes, reinforcing materials, seams, surfacing, drainage, coatings, waterproofing, and common repair conditions.
Siding is an important part of the full C-15 classification. Students should study exterior wall materials, weather barriers, fasteners, joints, trim, soffits, and flashing connections. ASTM D4756 provides technical information related to rigid PVC siding and soffit installation.
Roofing safety is another official examination subject. Roofing contractors must recognize fall hazards, ladder risks, scaffold safety concerns, and proper use of protective equipment. OSHA construction safety references support study but are not listed as permitted C-15 trade-exam-room books.
Photovoltaic roofing systems are also included in the current examination. Students should understand the effect of rooftop solar components on roof penetrations, flashing, waterproofing, and maintenance.
Roofing Construction and Estimating is a useful supplemental study reference. It explains roof measurements, material quantities, project estimates, roofing installation methods, and repairs. Accurate estimating can help contractors improve planning and avoid costly business errors.
Contractor Exam Preps offers a Nevada C-15 Roofing and Siding Exam Book Package containing the 2018 IBC and multiple roofing, siding, safety, estimating, and photovoltaic publications.
