Savannah Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this county for over twenty years, and if there’s one thing I tell every homeowner on the bluff, it’s that Savannah sits right in the bullseye for spring and fall severe weather. We’re nestled in that bend of the Tennessee River, and the way the hills funnel down toward the water creates a natural wind tunnel. When those big supercell storms roll in from the southwest—usually March through May, and again in late October—they get squeezed by that terrain and spin up straight-line winds that hit 70, 80 miles an hour. I’ve seen shingles that were nailed down perfectly just peeled back like a sardine can because the wind gets under that leading edge and there’s nowhere for the pressure to go. And it’s not just the wind; those same storms drop hail the size of golf balls, and with the humidity off the river, the ice gets this weird, jagged edge to it that chews up asphalt like a belt sander.

The real kicker is that our storm season doesn’t give you a break. We get those pop-up afternoon thunderstorms all summer long, and while they might not be as violent, they’re relentless. That constant cycle of baking heat in July and then a sudden cool-down from a thunderstorm makes the roof deck expand and contract, which loosens the seal between the shingles. So by the time a real hail event hits—like the one in 2020 that damaged half the houses on Main Street—your roof is already vulnerable. The hail doesn’t have to be huge to do damage; even dime-sized stones, when they’re driven by that river wind, can knock the granules off and expose the fiberglass mat. Once that happens, the sun does the rest, and you’re looking at leaks within a year. It’s not a matter of *if* you’ll get hit, it’s a matter of *when*, and I’ve got the photo albums on my phone to prove it.
