Roofs in Canon, GA: home ages, storms and what to plan for
About 1,895 homes stand in Canon, GA. The largest share was built in the 1990s (29%), and about 78% 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
53% of homes are single-family detached houses and 83% 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.
