Roofing Permits & Regulations Savannah GA

When Do You Need a Roofing Permit in Savannah?

Chatham County and the City of Savannah require building permits for roofing work that involves structural changes or complete re-roofing. Understanding when a permit is required — and what happens if you skip it — protects your investment and keeps your project on the right side of local regulations.

Permit Required

• Complete roof replacement (tear-off and re-roof)
• Roof overlay (installing new shingles over existing — note: Georgia code limits this to one overlay layer)
• Any structural modifications: adding skylights, changing roof pitch, removing or adding dormers
• Converting roof type (e.g., from shingles to metal) when structural modifications are needed
• Major repairs affecting more than one roof section or involving decking replacement

Permit Typically Not Required

• Minor repairs: replacing a few damaged shingles, re-sealing flashing, fixing small leaks
• Gutter replacement (unless attached to structural fascia modifications)
• Emergency temporary repairs (tarping) — though permanent repairs following emergency work do require permits

The Permit Process in Chatham County

Here's what the standard permitting process looks like for a residential roof replacement in the Savannah metro area:

• Application submission: Your contractor submits the permit application to the Chatham County Building Safety and Regulatory Services department (or City of Savannah Development Services if within city limits). The application includes project scope, material specifications, and contractor license information.
• Review period: Standard review takes 3–10 business days. Straightforward re-roofing permits are often processed faster than complex structural modifications.
• Permit issuance: Once approved, the permit must be displayed at the job site during construction. Your contractor should post it visibly.
• Inspection: After completion, a county or city building inspector examines the finished work for code compliance. Common inspection points include fastening patterns, underlayment installation, flashing details, and ventilation adequacy.
• Final approval: Passing inspection closes the permit. This documented approval becomes part of your property record and proves the work was done to code — valuable for insurance claims and property sales.

Georgia Building Code Requirements for Roofing

Georgia adopts the International Building Code (IBC) and International Residential Code (IRC) with state amendments. For Savannah-area roofing, the most impactful code requirements include:

Wind Resistance

Savannah falls within a high-wind zone due to our coastal location and hurricane exposure. Current code requires:

• Shingles rated for the design wind speed of the specific location (typically 130–150 mph in the Savannah metro)
• Enhanced fastening patterns: 6 nails per shingle in high-wind zones vs. the standard 4
• Starter strip adhesion requirements at eaves and rakes
• Wind-rated ridge cap installation

Underlayment

Code requires synthetic underlayment or ice-and-water shield membrane in specific locations. For Savannah's wind zone, enhanced underlayment requirements at eaves, valleys, and around penetrations exceed what many northern jurisdictions require. Self-adhering ice-and-water shield is required at vulnerable points regardless of the region's minimal ice dam risk — in our case, it serves as critical wind-driven rain protection.

Ventilation

Georgia code requires minimum attic ventilation ratios: 1:150 (1 sq ft of net free ventilation per 150 sq ft of attic floor) as the standard, reducible to 1:300 when ventilation is balanced between intake and exhaust with a vapor retarder installed. Given Savannah's humidity, exceeding minimum ventilation requirements is strongly recommended.

Roof Layering Limits

Georgia code permits a maximum of two layers of asphalt shingles (original plus one overlay). If your home already has two layers, complete tear-off to bare decking is required before installing new roofing — no exceptions. This is both a structural requirement (multiple layers add significant weight) and a quality requirement (proper inspection of decking condition requires full tear-off).

Historic District Regulations

Properties within Savannah's Landmark Historic District and Victorian Historic District face additional regulatory requirements that don't apply to properties in Pooler, Richmond Hill, or non-historic areas. The Historic District Board of Review (HDBR) governs exterior modifications including roofing materials and colors visible from public rights-of-way.

• Material approval: The HDBR may restrict material choices to maintain historical character. Replacement with like-kind materials (e.g., slate with slate, metal with metal) is generally approved without full board review.
• Color restrictions: Roofing material colors visible from the street may need to be compatible with the district's historical palette.
• Certificate of Appropriateness: Major changes (such as switching from slate to architectural shingles) require a Certificate of Appropriateness from the HDBR. The review process adds 2–6 weeks to the project timeline.
• Staff-level review: Minor changes and like-kind replacements can often be approved at staff level without a full board hearing, significantly reducing the timeline.

What Happens If You Skip the Permit?

Some contractors suggest skipping permits to save time and money. This is a serious mistake with real consequences:

• Fines and stop-work orders: Chatham County can issue fines and halt construction until permits are obtained retroactively
• Insurance denial: If unpermitted work contributes to a later claim (e.g., a leak from improper installation), your insurance company may deny coverage
• Warranty voidance: Many manufacturer warranties require code-compliant installation verified by inspection
• Sale complications: Unpermitted work discovered during a home sale can delay or kill transactions, or require costly retroactive permitting and inspection
• Liability exposure: If unpermitted work causes injury or property damage, the homeowner bears enhanced liability

Your Contractor Should Handle This

A professional Savannah roofing contractor handles the permitting process as part of their standard project scope. They should pull the permit under their contractor license, schedule the required inspections, and provide you with the closed permit documentation upon completion. If a contractor suggests you pull the permit yourself, or proposes to work without one, consider that a disqualifying red flag.
