Current PSI exam structure: the Alabama Roofing and Sheet Metal Contractor trade exam contains 60 questions in 150 minutes and requires 70% to pass. Review the official PSI Alabama Candidate Bulletin before testing.
Alabama regulates general contracting through the Alabama Licensing Board for General Contractors. Roofing and Sheet Metal is a specialty contractor classification associated with Building Construction and moisture-protection work.
Short answer: this classification is intended for contractors whose approved scope includes roofing and related sheet-metal work. Applicants must meet the Board's qualification requirements and pass the examinations required for the licensing path.
Current Alabama law generally requires a general contractor license when covered work reaches $100,000 or more in labor and materials. The Board controls licensing scope, application requirements, classifications and bid limits; PSI administers the contractor examinations.
This guide combines the current PSI Roofing and Sheet Metal trade exam, Business and Law exam, approved references, licensing steps and a structured contractor exam prep system for open-book testing.
Match your contractor classification and documented experience to the roofing and sheet-metal work you plan to perform.
| Work Area | What It Covers | Exam Prep Focus |
|---|---|---|
| Steep-Slope Roofing | Roof coverings, assemblies, underlayments, flashings, drainage and installation methods | Part of the 27-question roofing category |
| Low-Slope & Membrane Roofing | Built-up roofing, membrane systems, insulation, drainage and waterproofing assemblies | Part of the 27-question roofing category |
| Estimating & Plan Reading | Roof measurements, takeoffs, quantities, pitch, plans and project specifications | 10 PSI questions |
| Roofing Components | Flashing, edges, penetrations, drainage details and sheet-metal roof components | 9 PSI questions |
| Surface Preparation & Planning | Roof-deck evaluation, substrates, preparation and work planning | 8 PSI questions |
| Construction Safety | OSHA construction safety, fall protection and related jobsite requirements | 6 PSI questions |
Actual license scope depends on Alabama law, Board rules and the classification printed on the license. Confirm uncertain work directly with the Board before bidding or contracting.
Separate classifications, specialty-trade licenses, permits and professional credentials may still apply.
| Activity | Additional Authority | Important Note |
|---|---|---|
| Building Construction outside the specialty scope | A broader Building Construction classification may be required | A specialty classification does not automatically authorize unrestricted building work |
| Electrical contracting | Applicable Alabama electrical license | Roofing licensure does not replace electrical licensing requirements |
| Plumbing or gas fitting | Applicable plumbing or gas-fitting credential | Use properly credentialed specialty contractors when required |
| HVAC contracting | Applicable HACR contractor license | Mechanical trade licensing is separate |
| Engineering or architectural services | Professional licensure may apply | A contractor license is not a professional design license |
| Local permits and inspections | Local building department requirements | State contractor licensure does not eliminate local permitting |
Use the Board's classification rules for legal scope. Contractor exam prep teaches tested material; actual authority comes from Alabama law and the license issued to the contractor.
The Alabama Roofing and Sheet Metal Contractor trade exam and Alabama Business and Law exam are administered through PSI. Open-book contractor exam prep should combine roofing knowledge with fast reference navigation.
Use the current official numbers. The PSI outline lists 60 trade questions in 150 minutes with a 70 percent passing score.
It is open book. Only approved references that comply with PSI rules may be used.
It is still time-sensitive. Candidates average about two and one-half minutes per scored trade question, so exam prep should train fast subject identification and book lookup.
Roofing dominates the outline. Steep and Low Slope Roofing, including BUR and Waterproofing, accounts for 27 of the 60 questions.
The trade exam rewards candidates who can move quickly between roofing manuals, the 2021 International Building Code, Roofing Construction and Estimating, and OSHA under time pressure.
Simplified study illustration. Use the official PSI references for actual exam answers.
Train each practice question as a lookup sequence: identify the roofing subject, select the correct reference, locate the chapter or index term, confirm the requirement or method, then return to the exam.
| Skill | What to Practice | Common Mistake |
|---|---|---|
| Steep-slope roofing | Roof coverings, underlayments, flashing, edges and installation methods | Underestimating the largest exam category |
| Low-slope roofing | BUR, membrane systems, insulation, drainage and waterproofing | Using field habit instead of the listed reference |
| Estimating & plans | Roof area, pitch, takeoffs, material quantities, plans and specifications | Skipping calculations during exam prep |
| IBC navigation | Definitions, chapters, tables, roofing provisions and index terms | Reading long code sections instead of targeted lookup |
| OSHA safety | Fall protection, ladders, scaffolds, PPE and construction safety | Trying to memorize OSHA instead of learning navigation |
| Time management | Two-and-one-half-minute pacing, skip-return strategy and timed sets | Spending too long on one difficult lookup |
Practice the lookup path, not only the answer. After every practice question, identify the reference and index term that got you there. That process builds open-book contractor exam speed.
Seven steps take you from the correct classification to completed Alabama contractor licensing.
Review the Board's classification rules and make sure Roofing and Sheet Metal matches your documented work experience and intended project scope.
Use the current Alabama prime contractor application information and provide the classification, experience, references and financial documentation the Board requires.
Verify the Roofing and Sheet Metal trade exam, Business and Law requirement, exam format, content outline, approved reference books and testing rules.
Study according to the official topic weights, prepare compliant permanent tabs and highlighting, practice roofing calculations and complete timed reference-navigation drills.
After Board approval, register for the appropriate Alabama contractor examinations through PSI.
Complete the Roofing and Sheet Metal Contractor trade exam and the applicable Alabama Business and Law examination requirements.
Satisfy the Board's remaining requirements for the contractor license, classification and bid limit.
Study according to the current 60-question PSI outline. The bars show question count relative to the largest category.
| Business and Law Topic | Questions | Study Focus |
|---|---|---|
| Licensing | 8 | Board requirements, licensing rules and responsibilities |
| Payroll and Taxes | 6 | Payroll, tax obligations and records |
| Contracts | 6 | Contract terms, administration and obligations |
| Estimating and Bidding | 5 | Estimating, pricing structure and bid process |
| Financial | 5 | Financial management and business controls |
| Personnel and Labor | 5 | Employment and labor responsibilities |
| Risk Management | 4 | Insurance, risk and contractor exposure |
| Safety Recordkeeping and Environmental | 4 | Records, compliance and environmental responsibilities |
| Project Management | 3 | Planning, scheduling and project controls |
| Liens and Business Organization | 2 each | Lien fundamentals and company structures |
The official PSI content outline should control your study calendar. Allocate the most exam prep time to the 27-question roofing category, then reinforce estimating, components, preparation and safety with timed contractor exam drills.
Use the exact editions listed in the current PSI bulletin and your current exam authorization.
| Reference | Primary Use | Prep Priority |
|---|---|---|
| Code of Federal Regulations - 29 CFR Part 1926 (OSHA) | Construction safety, fall protection and OSHA requirements | Core Safety reference |
| International Building Code, 2021 | Building-code requirements, roof assemblies and code navigation | Core code reference |
| Roofing Construction and Estimating, Daniel Atcheson | Roofing methods, materials, estimating and field calculations | High priority trade reference |
| NRCA Roofing Manual: Steep-Slope Roof Systems, 2025 | Steep-slope roofing systems, components and installation practices | High priority for the 27-question roofing category |
| NRCA Roofing Manual: Membrane Roofing Systems, 2023 | Low-slope, membrane, BUR and waterproofing systems | High priority for the 27-question roofing category |
| NASCLA Contractors Guide to Business, Law and Project Management, Alabama General, 3rd Edition | Alabama Business and Law exam | Core business reference |
Use the current PSI bulletin. Reference lists and editions can change. Verify the bulletin tied to your current eligibility before ordering books or reporting for the exam.
PSI reference rule: approved references may be highlighted, underlined and indexed, but must otherwise comply with PSI's examination-reference requirements. Permanent tabs are allowed; temporary tabs and additional papers are not.
The Alabama Licensing Board for General Contractors requires the applicable Business and Law examination as part of the prime contractor licensing path. The current PSI exam contains 50 questions, allows 120 minutes and requires 70 percent to pass.
Licensing is the largest individual category with eight questions. Payroll and Taxes and Contracts contain six questions each, while Estimating and Bidding, Financial, and Personnel and Labor contain five each.
The current listed business reference is the NASCLA Contractors Guide to Business, Law and Project Management, Alabama General, 3rd Edition.
The correct Alabama contractor path depends on the scope and documented experience you can support.
| Path | Classification Focus | Important Note |
|---|---|---|
| Roofing & Sheet Metal | Specialty roofing, waterproofing and related sheet-metal work within the issued scope | Request the specialty when your qualifying experience matches this work |
| Building Construction | Major building classification covering broader building structures and construction work | Broader documented experience and examination requirements apply |
| Building Construction Under Four Stories | Building construction within the Board's applicable height and scope limits | Scope differs from the Roofing and Sheet Metal specialty |
| Classification Amendment | Existing licensee requesting an additional or broader classification | Board review, qualifying projects, references and examination requirements may apply |
Classification matters. The Board bases license classifications on documented experience and the type of contracts the applicant is qualified to perform.
Use the official PSI outline to balance steep-slope roofing, low-slope systems, estimating, components, surface preparation, safety, Business and Law and timed reference navigation.
The challenge is not only knowing roofing. The PSI trade exam combines steep- and low-slope systems, waterproofing, estimating and plan reading, roofing components, surface preparation, planning and safety under a 150-minute time limit.
Common avoidable problems include slow book navigation, weak estimating practice, poor knowledge of the NRCA manuals, using outdated reference information, spending too long on individual lookups and neglecting the separate Business and Law exam. Structured contractor exam prep turns the official outline into a repeatable study system.
Passing the PSI examinations completes the testing portion of the licensing process, but it does not automatically issue the Alabama contractor license.
Complete the Alabama Licensing Board for General Contractors requirements for your application, Roofing and Sheet Metal classification and bid limit. The Board reviews experience, references, financial information and other required documentation before license issuance.
Use the final license classification exactly as issued when bidding or contracting, and keep the license current through the Board's renewal process.
Select preparation that supports the current PSI Roofing and Sheet Metal trade exam and Alabama Business and Law exam. Combine structured contractor exam prep with the actual reference books and timed lookup practice.

Alabama regulates general contractors to protect public safety and establish licensing standards.
· Use the Roofing and Sheet Metal classification only for work within the scope issued to you
· Follow separate specialty-trade licensing requirements when they apply
· Do not bid beyond the license classification or bid limit
· Maintain current Board licensing and renewal requirements
Use the correct licensing path before bidding, contracting or performing regulated general contracting work.
