“Greg Batista here, your friendly neighborhood engineer to answer your questions.
RoofRider77 asks: Why do Florida homes use those little metal straps on the roof?
Those small pieces of metal are hurricane clips, and they’re one of the most effective defenses against wind damage. After Hurricane Andrew, Florida law required them in new homes because so many roofs failed. Clips physically tie the roof trusses to the walls, preventing uplift. FEMA research shows homes with clips are 40% less likely to lose roofs during hurricanes. They cost only a few dollars per connection but save thousands in avoided repairs. In South Florida’s HVHZ, these clips are mandatory and inspected closely. Without them, an entire roof can peel away in minutes during a storm.
