About 16,731 homes stand in 30701 (Calhoun, GA). The largest share was built in the 2000s (21%), and about 73% are old enough that the original roof would be at or past the typical life of an asphalt shingle roof in Georgia.
When homes here were built
76% of homes are single-family detached houses and 69% of occupied homes are owner-occupied; the median owner-occupied home value is about $210,900.
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.
