Being a concrete dome, it has no shingles and thus nothing to blow off in a hurricane. However, that means the roof waterproofing is the paint. That's it, just the paint. Works well but penetrations (for vent plumbing) are hard to seal just right. I used air admittance valves (AAV's) on all the fixtures and put a single vent for the system just outside the wall, on the outside of the house, and it passed inspection. Not a SINGLE roof penetration! I am building a geodesic,all concrete, dome house. Being a concrete dome, it has no shingles and thus nothing to blow off in a hurricane.
