Roofing Permits and Building Codes in South Alabama
Roofing work in Mobile and Baldwin County is regulated by Alabama building code, local jurisdiction requirements, and ASCE 7 wind design standards. Understanding what permits are required, what the code mandates, and how inspections work protects your investment and ensures your roof meets the standards that actually matter in a hurricane zone.
Roofing Permit Requirements in Mobile and Baldwin County
Full roof replacement always requires a permit in Mobile and Baldwin County. This applies regardless of whether you're replacing shingles, installing metal, or reroofing a commercial building.

- Any structural changes to roof framing or decking
- New construction roofing

Always verify with your local jurisdiction — requirements vary by municipality and county. When in doubt, pull the permit.
Alabama Building Code and Wind Zone Standards for Roofing
Alabama adopted the International Building Code (IBC 2015) and International Residential Code (IRC 2015) as the statewide base code. Local jurisdictions (Mobile County, Baldwin County, City of Mobile, etc.) may adopt amendments — but the base code establishes the minimum standards that all roofing work must meet.
IRC Section R905 — Roofing Requirements
This section establishes minimum standards for all roofing materials. It covers installation requirements for asphalt shingles, metal roofing, tile, and flat roof systems. Key requirements include: minimum underlayment standards, fastener type and spacing, flashing requirements at all penetrations and transitions, and ridge cap installation. These are the code minimums — FORTIFIED™ standards exceed them.
ASCE 7-10 — Wind Design Requirements
The wind design standard used in Alabama's building code determines how roofs must be fastened. ASCE 7 wind maps divide the country into wind zones. South Alabama falls into the highest wind zones in the continental US:
- Mobile County: 140 mph design wind speed
- Inland Baldwin County: 140 mph design wind speed
- Coastal Baldwin County (within 1 mile of coastline): 160 mph design wind speed
These wind speeds drive enhanced fastening requirements — including ring-shank nails, six-nail patterns on shingles, and specific hip and ridge treatments. A roof installed to national average standards will not meet Alabama code in these zones.
Wind-Borne Debris Region Requirements
Properties within the wind-borne debris region face additional requirements. The Alabama building code designates areas within 1 mile of the coast (and some other high-wind areas) as wind-borne debris regions. In these areas, roof sheathing must be attached with specific ring-shank nail patterns and sealed at panel edges to limit water intrusion if sheathing is exposed. This requirement is essentially what FORTIFIED builds on top of — but it applies at the code level regardless of FORTIFIED.
Permit Process Differences: Mobile County vs. Baldwin County
Both counties use Alabama's statewide building code as the base, but permit processes, fees, and administrative requirements differ between jurisdictions.
| Factor | Mobile County / City of Mobile | Baldwin County Jurisdictions |
|---|---|---|
| Governing Authority | Mobile County Building Department / City of Mobile Building Services | Baldwin County Building Department (unincorporated) or city/town building departments |
| Base Code | Alabama Building Code (IRC/IBC 2015) | Alabama Building Code (IRC/IBC 2015) |
| Wind Design Zone | 140 mph (ASCE 7) | 140 mph (inland) / 160 mph (coastal — within 1 mile of coast) |
| Permit Fees | Typically $150–$400 based on project value | Varies by jurisdiction; similar range |
| Contractor Licensing | Alabama state license required (Home Builders Licensure Board) | Alabama state license required |
| Inspection Required | Yes — final inspection required before project closeout | Yes — varies by municipality |
Alabama Roofing Contractor Licensing: What the Law Requires
Alabama requires roofing contractors to be licensed through the Home Builders Licensure Board (HBLB). This is a state requirement that applies across all counties. Licensing verifies that the contractor meets minimum standards for training, experience, and insurance.
What to Verify Before Hiring a Roofer in Alabama
- Alabama HBLB License: Verify at the Alabama HBLB website or by asking for the license number. General contractors must have a license; roofing-specific subcontractors also need appropriate classification.
- General Liability Insurance: Minimum $1,000,000 per occurrence. Ask for a certificate of insurance naming you as the certificate holder.
- Workers' Compensation Insurance: Required if the contractor employs workers. Without it, you may be liable for injuries on your property.
- Permits pulled in the contractor's name: Any licensed contractor should pull permits. If they suggest you pull the permit as the homeowner (owner-builder exemption), that shifts liability to you and may void manufacturer warranties.
The Owner-Builder Exemption — and Why to Avoid It
Alabama law allows homeowners to act as their own general contractor for work on their primary residence. Some contractors suggest using this exemption to avoid permit requirements or to work without a license. This transfers all liability to you, may void your homeowners insurance coverage for the work, and will void most manufacturer warranties. Never agree to this arrangement.
Documents Your Roofing Contractor Should Handle
- Building permit application and fees
- Materials specification for code compliance
- Wind zone documentation (ASCE 7-10)
- Manufacturer warranty registration
- Post-installation inspection scheduling
- FORTIFIED evaluation coordination (if applicable)
- Final inspection sign-off and certificate
- Permit closure with local building department
Post-Installation Roof Inspection: What Code Enforcement Checks
The inspection process exists to confirm that the work was done correctly — not to make the contractor's job harder. For homeowners, a passed inspection is documentation that their roof meets code, which matters for insurance and resale.
Step 1: Permit Application
We submit the permit application to the relevant building department before work begins. Applications include project scope, materials specifications, and contractor licensing information. Most permits are approved within 1–5 business days for standard residential projects.
Step 2: Decking Inspection (If Required)
Some jurisdictions require inspection of the exposed roof deck before underlayment is installed. This verifies sheathing condition, fastening, and blocking. We schedule this inspection at the appropriate point in the installation sequence.
Step 3: Final Inspection
After completion, the building inspector visits to verify the installed roofing meets code requirements. They check flashing details, ridge cap installation, ventilation, and overall workmanship. A passed final inspection closes the permit.
Step 4: Permit Closeout
After the final inspection passes, the permit is closed and the record is filed with the building department. We provide a copy of the closed permit to every client — this is a document worth keeping for insurance claims and future home sales.
Unpermitted Roofing Work Puts Your Insurance and Resale Value at Risk
Permits exist to protect you, not to create paperwork for the contractor. Here is what's actually at stake when a contractor skips permits:
- Insurance claims can be denied. If a roof installed without permits suffers storm damage, your insurer may deny the claim on the grounds that the work was unpermitted and potentially non-code-compliant.
- Manufacturer warranties may be voided. Many shingle and metal roofing manufacturers require permitted installation as a condition of their product warranty. An unpermitted roof may have no warranty coverage.
- Home sale complications. Unpermitted work is a common discovery during real estate transactions. Buyers can demand remediation or price reductions. Some lenders won't approve mortgages on homes with open unpermitted work.
- You own the liability. An unpermitted roof means there was no inspection confirming code compliance. If something fails, the absence of permits makes it harder to establish that the work was done correctly.
- Contractors without licenses don't pull permits. The unwillingness to pull a permit is often a signal that the contractor is not properly licensed or insured.
