Roofs in Summerville, GA: home ages, storms and what to plan for

Summerville, GA has about 7,121 homes. Most were built in the 1970s, which tells you a lot about where its roofs are in their life: about 84% of homes would be on at least their second roof by now.

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.

69% of homes are single-family detached houses and 66% of occupied homes are owner-occupied.

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.
