What to know about water damage in Newnan
28%
Share of Newnan homes built in 2010 or later; the median year built is 2004, 58% are owner-occupied, and 21% are in buildings with 10 or more units. In an apartment or townhouse, a leak from the unit above is the most common source of damage, so know where your own shutoff is.
The 2021 tornado
Early on March 26, 2021, an EF4 tornado struck Newnan directly, damaging homes and the historic downtown and badly damaging Newnan High School, which was rebuilt. Wind damage that opens a roof becomes water damage with the next rain, so tarp it the same day.
