Georgia Reroofing Code: The Real Rule (Not 25%) — When Tear-Off Is Required
If you’ve been told “Georgia code says if 25% is damaged the entire roof must be replaced,” that’s a common misconception (often imported from Florida). Georgia reroofing compliance is usually about recover vs tear-off, roof layers, substrate condition, and installation details—not a blanket statewide percentage trigger.

Quick answer
Enforcement and amendments can vary by city/county. Always confirm for your address with the building department.
The real rule: when tear-off is required
Under standard IRC reroofing logic commonly quoted in Georgia permit guides, new roof coverings must not be installed over existing coverings (i.e., tear-off is required) when any of these conditions exist:
- Water-soaked / deteriorated base: the existing roof/covering is not adequate as a base for additional roofing.
- Restricted existing materials: wood shake / slate / clay / cement / asbestos-cement tile (as listed in local guides).
- Too many layers: the roof already has two or more applications/layers of roof covering.
Translation: Georgia reroof compliance is usually about method + substrate + layers, not a statewide percentage trigger.
Drip edge: a common Georgia reroof compliance item
Georgia jurisdictions frequently cite IRC shingle-roof requirements for drip edge at eaves and gables, including overlap, extension dimensions, fastening spacing, and underlayment sequencing (over drip edge at eaves; under at gables).
