Roofs in 30168 (Austell, GA): home ages, storms and what to plan for

In 30168 (Austell, GA), about 71% of homes were built long enough ago that their original roofs would already be due, and the biggest group of houses dates to the 1980s.

When homes here were built

Share of homes by decade built (Census ACS 2023 5-year). Clay bars: built long enough ago that the original roof would be at or past a typical asphalt shingle lifespan in Georgia.

54% of homes are single-family detached houses and 50% of occupied homes are owner-occupied; the median owner-occupied home value is about $229,400.

Most homes here are old enough to be on a second or even third roof. That changes what matters at replacement time: decking that has been nailed through twice, flashing that may have been reused before, and attic ventilation that was never brought up to current practice. See roof decking and ventilation basics.
