Roofing Lessons Learned from Hurricane Katrina
Roofing Industry Committee on Weather Issues, Inc's. Hurricane Katrina Wind Investigation Report, prepared in conjunction with Oak Ridge National Laboratory, assesses damage to roofing caused by Hurricane Katrina in August of 2005.
One major finding: Peak gust speeds in the inspected areas were estimated at 120 - 130 mph, below the 130 - 150 mph basic design wind speeds required by current codes. As hoped, roofs constructed to current code requirements faired relatively well. Most failures of such roofs were attributable to improper installation or deterioration rather than flaws in the design methodology.

Having spent considerable time working in Katrina land I agree with the author. Much of what I was hired to replace were old worn out bur's or failed roofs from improper installations. Typical of a poorly installed roof was the perimeter metal flashings not having a sufficient number of fasteners holding the metal to the wood blocking at the perimeter.
