Alpharetta is mostly a 1990s-and-newer town: about 36% of homes with a known build year went up in the 1990s and another 40% since 2000. If your house is from that 1990s wave and still has its first roof, ask any roofer to check the decking and ventilation, not just the shingles.
Storms have kept roofers busy here. Our data shows 17 days with hail of an inch or larger in the last two years. On Sep 5, 2026, hail up to 1.25 inches passed over about 28% of Alpharetta homes, and gusts of 58 mph or more reached nearly all of them.
Inside city limits, Alpharetta's development code lists a roof covering replacement with no structural changes as work that doesn't need a building permit; structural work does. HOA approval is a separate step and doesn't replace a city permit. And an Alpharetta mailing address doesn't guarantee the home is inside city limits, so have your roofer confirm the jurisdiction from the street address.

Permits and paperwork
- Reroofing
- Alpharetta's Unified Development Code, Sec. 4.4.5(A), Exception No. 2, lists "Roof covering replacements not involving any structure modifications" as work that does not need a building permit. The city's Residential Permitting Procedures say building permits are required before any construction work except work exempted under Exceptions No. 1 and No. 2 to that section. Source
If the mailing address is Alpharetta but the property is in another municipality, use that municipality's actual permitting process instead of Alpharetta's.
- Alpharetta's Residential Permitting Procedures (revised 2026) say Georgia has required a state contractor's license for residential contracting since July 1, 2008. The contractor must show the license, the qualifying agent's license and photo ID when first applying for a city permit. Single-trade Limited Specialty Contractors are exempt from state licensing, and the city says to check with its office if you're unsure. See the Residential Permitting Procedures.
- The same document says HOA approval does not replace a city permit. The city strongly encourages homeowners in subdivisions with covenants to get written HOA approval before starting a project.
- Alpharetta building permit applications and plans are submitted through the city's online Permitting Portal.
