Most houses have hurricane protection so why are the roof vents unprotected?

Most Florida houses have hurricane protection on the windows and doors. Impact glass windows, fabric shutters, metal shutters and hurricane grade garage doors serve to protect the home in the event of a storm. However, the roof vents are wide open, leaving the house completely unprotected. Roof vents typically have large openings into the attic space making the attic “transparent” to the exterior. Any storms over 40 miles an hour push wind driven rain into your attic. The Hurricane Blockers is designed to stop water intrusion through the roof top vents which are a major source of water intrusion during storms.
