"When I originally wrote this segment for the web site in 2001, I had no idea how quickly the Dome of a Home would be put to the test. As we were building the dome, Tropical Storm Isadore came ashore and left a mess, but no damage. Then, in 2004, Hurricane Ivan slammed into Pensacola Beach wreaking enough havoc that it was called Ivan, The Terrible. Although many of my neighbors' houses were piles of rubble or completely washed away, the dome suffered no structural damage. The Dome's front staircase was designed to break away (which it did) to avoid damage to the actual structure.
The 2005 hurricane season brought several storms to our shore: Tropical Storm Arlene in June; Hurricane Dennis in July; and Katrina in August. Hurricane Dennis was an extremely damaging storm to Pensacola Beach. Much to the community's dismay, many of the repaired homes and buildings that made it through Ivan were decimated by Dennis. Again, the Dome of a Home suffered no structural damage. We had repairs to underground wells, exterior electrical and plumbing issues, etc. but no damage to the dome itself." - Valerie Sigler
