ICC National Roofing Contractor-Subcontractor - G14-N Exam - Online Practice Questions

Prepare for the ICC National Roofing Contractor-Subcontractor G14-N exam with online practice questions designed to strengthen roofing-code knowledge, improve reference-navigation skills, and reinforce the construction requirements that roofing contractors need to understand for the examination. This preparation product includes 3 months of access and uses the International Building Code, 2018, International Residential Code for One- and Two-Family Dwellings, 2018, and International Plumbing Code, 2018.

The ICC Roofing Contractor examination focuses on the code requirements and construction knowledge associated with roofing work on residential and commercial projects. Candidates should be prepared for questions involving administration, code terminology, job planning, roof covering materials, shingles, flat-roof systems, membranes, fasteners, flashing, roof drainage, scuppers, gutters, reroofing, and roof-ceiling assemblies.

Roofing contractor preparation requires more than recognizing familiar roofing materials. Candidates must be able to locate and apply requirements from three different code books. Commercial roofing provisions are primarily addressed through the 2018 International Building Code, residential roofing requirements are found throughout the 2018 International Residential Code, and roof drainage requirements are supported by the 2018 International Plumbing Code.

Because the examination is open book, candidates should study the references as working tools. Understanding where roof assemblies, covering materials, flashing, drainage, reroofing, definitions, and related requirements are located can make a significant difference when answering questions under a timed testing format.

The online practice questions provide an active way to prepare. Candidates can identify the roofing subject being tested, determine which reference applies, locate the governing section or table, and reinforce the reasoning needed to handle similar contractor-level questions.

Exam Details

The ICC G14 Roofing Contractor examination contains 60 multiple-choice questions and has a 3-hour time limit.

The official examination outline identifies four major content areas:

• Administration and General Requirements – 28%
• Types of Roofing Material and Application – 35%
• Fasteners, Flashings, Drainage, and Scuppers – 28%
• Re-Roofing – 12%

Types of Roofing Material and Application is the largest examination category at 35%. Candidates should be prepared for questions involving shingle roofing, flat roofs, hot-mopped systems, and other membrane roofing applications. Understanding how different roof covering materials are regulated is a major part of the exam.

Administration and General Requirements represent 28% of the official outline. This section includes administration, code definitions and terms, and job planning and setup. Roofing contractors need to understand how code requirements are organized and how general administrative provisions affect roofing work.

Fasteners, Flashings, Drainage, and Scuppers also represent 28%. This section includes fasteners, flashing and accessory materials, roof drains, gutters, and scuppers. Candidates should understand how roofing systems are secured, how transitions and penetrations are protected from water entry, and how water is directed from roof surfaces.

Re-Roofing represents 12% of the outline and includes removal of existing roofing materials, adding additional layers where permitted, and repairing roof structures and roof-ceiling assemblies. Reroofing questions require careful attention to the condition of the existing roof and the requirements that determine whether removal, repair, or additional covering is allowed.

The examination references for the 2018 code cycle are the 2018 International Residential Code, 2018 International Building Code, and 2018 International Plumbing Code. Candidates should practice moving efficiently among all three books.

Open Book Test

The ICC G14 Roofing Contractor examination is an open book test. Candidates have three hours to complete 60 multiple-choice questions and must follow current ICC examination rules regarding permitted references and testing materials.

The exam format gives candidates an average of approximately three minutes per question. That allows time for code lookup, but it is still important to know where information is located. Searching all three code books from the beginning for every question is not an effective strategy.

Successful open-book preparation should begin with reference recognition. A commercial roof covering or roof assembly question will often direct attention toward the 2018 International Building Code. A residential shingle, roof-ceiling, or one- and two-family dwelling question will generally lead toward the 2018 International Residential Code. A roof drainage question may require the International Plumbing Code.

Candidates should become familiar with tables of contents, indexes, definitions, chapter organization, tables, figures, footnotes, and exceptions. Roofing questions often depend on specific installation conditions, and a small exception or material limitation can change the correct answer.

Practice questions can be used as navigation exercises. After answering, locate the supporting provision and review the surrounding material. This strengthens familiarity with both the roofing requirement and its location within the code.

Licensing Steps

The ICC G14 Roofing Contractor examination is part of the ICC Contractor/Trades examination program. ICC evaluates technical knowledge, while the applicable state or local licensing authority determines whether the examination is accepted for a roofing contractor or subcontractor credential.

1. Identify the required roofing credential. Determine whether the ICC G14 Roofing Contractor examination is required or accepted by the jurisdiction where you plan to perform roofing work.
2. Review jurisdiction requirements. Confirm any experience, application, registration, insurance, business, or other requirements established by the applicable licensing authority.
3. Prepare with the correct references. This preparation product uses the 2018 International Building Code, 2018 International Residential Code, and 2018 International Plumbing Code.
4. Study by official content area. Organize preparation around Administration and General Requirements, Types of Roofing Material and Application, Fasteners and Flashings, Drainage and Scuppers, and Re-Roofing.
5. Develop three-code navigation skills. Practice identifying whether a question belongs primarily in the IBC, IRC, or IPC.
6. Review roofing materials and applications. Study shingles, flat roofing, membranes, flashing, fasteners, and other roofing systems identified in the examination outline.
7. Practice roof drainage. Learn to locate requirements involving roof drains, gutters, leaders, conductors, and scuppers.
8. Use the online practice questions. Work through roofing scenarios and revisit weaker subjects during the included 3-month access period.
9. Register for the examination. Follow the current ICC Contractor/Trades registration and scheduling process.
10. Complete jurisdiction requirements. After the exam, follow any additional licensing steps established by the state or local authority.

State Requirements

The ICC G14 Roofing Contractor examination is a national contractor/trades examination. Passing the exam does not automatically create a roofing contractor license that is valid in every state, county, or municipality.

Roofing contractor licensing requirements vary by jurisdiction. A state or local authority determines whether the ICC examination is accepted and what additional qualifications must be completed before a contractor can legally perform regulated roofing work.

Requirements can differ depending on the type of roofing work, project value, business structure, local licensing classification, or whether the work is residential or commercial. The technical exam is only one part of the process where licensing is required.

Candidates should confirm that the G14 examination and 2018 code cycle correspond to the roofing contractor or subcontractor credential required by their licensing jurisdiction.

Test Information and Study Materials

This online practice-question product includes 3 months of access. Candidates can use the access period to divide the examination into manageable subjects and repeatedly practice locating roofing requirements across the three code books.

Begin with Types of Roofing Material and Application because this is the largest category. Review shingle roofing, flat roofing, hot-mopped systems, and other membranes. Candidates should understand that each roofing material can have different requirements for slope, underlayment, fastening, application, flashing, and installation.

Shingle roofing should receive focused attention. Residential and commercial applications can involve requirements for roof slope, underlayment, fastening, flashing, weather protection, and material installation. Candidates should practice locating the specific provisions that apply to the roof covering described in a question.

Flat-roof and membrane systems also deserve dedicated study. Low-slope roofing systems can involve different materials and application methods than steep-slope roofs. Questions may require candidates to distinguish among roofing systems or identify requirements associated with membranes and related materials.

Next, review Administration and General Requirements. Learn how code administration, definitions, and job planning influence roofing projects. Definitions are especially important because code terminology can determine which section applies to a particular roof system or condition.

Job planning and setup can involve understanding the work being performed, project conditions, and code requirements that must be considered before installation. Roofing contractors should be able to connect practical jobsite conditions with the applicable code provisions.

For Fasteners, review how roofing materials are attached and how fastening requirements vary by material and application. The correct fastener, spacing, attachment method, or substrate condition can affect the compliance of a roofing installation.

For Flashings and Accessory Materials, study the locations where roofing systems must transition around walls, penetrations, chimneys, valleys, edges, and other interruptions. Flashing protects vulnerable roof transitions from water intrusion and is a major part of proper roof-system performance.

Candidates should learn to recognize the location described in a question before beginning the lookup. A valley, sidewall, roof penetration, chimney, or roof-to-wall intersection may have different flashing requirements.

Roof Drainage should be studied with the 2018 International Plumbing Code. Review roof drains, gutters, conductors, leaders, scuppers, overflow drainage, and related storm drainage provisions.

Drainage questions may require candidates to determine how water is removed from a roof surface or how secondary drainage is provided. Candidates should become familiar with the IPC organization so they can move directly to the applicable storm drainage provisions.

Scuppers deserve particular attention because they may serve as part of primary or secondary roof drainage arrangements depending on the design. Candidates should understand how roof-edge drainage components relate to the larger drainage system.

For Re-Roofing, study when existing roofing materials must be removed, when additional roof covering may be installed, and how damaged roof structures or roof-ceiling assemblies are handled. Questions often depend on the existing number of layers, material condition, or structural condition described.

Reroofing questions should be read carefully because the correct answer may depend on whether the work is a replacement, repair, additional layer, or structural correction. Candidates should not assume that new roofing can always be installed directly over an existing covering.

The 2018 International Residential Code is particularly important for one- and two-family dwelling roofing. Review roof-ceiling construction, roof sheathing, ventilation, roof coverings, shingles, tile, metal systems, wood shingles and shakes, flashing, and reroofing.

The 2018 International Building Code should be reviewed for commercial roofing requirements. Study roof assemblies, roof covering classifications, weather protection, material requirements, reroofing, rooftop structures, and other provisions that affect nonresidential roof systems.

The 2018 International Plumbing Code should be treated as an essential reference rather than an unrelated plumbing book. Roofing contractors need to understand roof drainage because water accumulation, overflow, scuppers, drains, and conductors directly affect roof performance.

Timed practice should be included throughout preparation. The examination allows 180 minutes for 60 questions. Straightforward code questions can often be completed quickly, preserving more time for detailed material requirements, drainage problems, or questions that require switching among references.

When a practice question is missed, determine why. The problem may involve using the wrong code book, misunderstanding a roofing material, overlooking an exception, selecting the wrong drainage provision, or failing to recognize the type of reroofing condition described.

Use missed questions to guide later study sessions. If roof drainage questions are difficult, devote more time to the IPC. If shingle or membrane questions take too long, review the organization of the roofing chapters in the IBC and IRC. If flashing questions create uncertainty, focus on material-specific and location-specific requirements.

A strong roofing contractor study plan combines code familiarity, roofing trade knowledge, reference navigation, and repeated exam-style practice. The goal is to understand not only what the requirement says, but also where it is located and when it applies.
