Roof Replacement — Alabama license requirements
01 The project
The starting point is the work itself — Roof Replacement in Alabama. The job determines which trades are involved, and the trades determine which license classifications may be required.

02 Jurisdiction
This project is evaluated for Alabama — the five-board / two-threshold state. Non-residential work of $100,000 or more (pools $5,000) is the ALBGC general contractor layer; residential work over $10,000 (roofing over $2,500) is the HBLB home builder layer; and the electrical (AECB, ch. 36), plumbing/gas (PGFB, ch. 37) and HVAC/R (HACR, ch. 31) trades are licensed by their own boards. Alabama jurisdiction page.
Municipal building-permit and business-licence fees are set locally and were not read — LOCAL_AUTHORITY_REQUIRED. Alabama publishes a single confirmed contractor bond (the HVAC/R $20,000 performance bond) and no general contractor bond, so no other bond amount appears here to verify against. State requirements are not the complete story for any locality.

06 Rule: AL-HB-ROOFER
The residential home builder definition includes a residential roofer when the cost of the undertaking exceeds $2,500 (§34-14A-2(12)); a residential roofer installs products or repairs surfaces on the external upper covering that seals, waterproofs or weatherproofs the residence (§34-14A-2(13)). An Unlimited home builders licence covers roofing without a separate roofer licence. Missing facts yield NOT_DETERMINED.

09 Rule: AL-TWO-THRESHOLD
Alabama applies TWO different contractor thresholds depending on whether the work is residential. Non-residential commercial/industrial/public work of $100,000 or more (and swimming pools of $5,000 or more) falls to the Licensing Board for General Contractors (chapter 8, Title 34; the threshold was raised from $50,000 by Act 2024-277, effective 2024-10-01). Residential home building over $10,000 (residential roofing over $2,500) falls to the Home Builders Licensure Board (chapter 14A, Title 34). Underneath both run the separate trade boards — electrical, plumbing/gas and HVAC/R. Missing facts yield NOT_DETERMINED.

| Statewide roofing credential | a residential roofer must be licensed when the cost of the undertaking exceeds $2,500 (§34-14A-2(12)); the scope is installing products or repairing surfaces on the external upper covering that seals/waterproofs/weatherproofs the residence (§34-14A-2(13)) | S-AL-HBLB-LAW |
| Alternative credential | an Unlimited home builders licence is qualified to engage in residential roofing without a separate roofer licence | S-AL-HBLB-LAW |
| Homeowner building their own residence | §34-14A-6(5) exempts the owner — a nontransferable privilege; a sale within one year of substantial completion forfeits it | S-AL-HBLB-EXEMPTIONS |
| Does the GC board licence apply? | no — the ALBGC licence is the $100,000 non-residential layer; ordinary residential roofing is the HBLB's | S-AL-GC-LAW |
| Building permit | municipal — issued by the local building department; §34-8-9 ties permit issuance for covered work to state licensure | S-AL-GC-LAW |
| Roofer bond | no amount published — commercial materials circulate $10,000 (CONFLICT-AL-004) | S-AL-GC-LAW |
11 Permit and verification layer
Alabama separates the credential from the permit: the STATE boards decide who may work (the ALBGC / HBLB / AECB / PGFB / HACR licences and certificates), while the municipal building department issues the building permit and the city/county issues a business licence. §34-8-9 ties building-permit issuance for covered work to the state licensure framework. Permit and business-licence fees are set locally and were not read — LOCAL_AUTHORITY_REQUIRED. S-AL-GC-LAW
