It is hurricane season again and it looks like this year may be an active season. If this week is any indication, we may face multiple high-impact storms as we did in 2004 and 2005.

Hurricane experts have told us that we are in a 10-year
cycle where the potential for more hurricanes exists. We all seem to have
forgotten those claims the last two years, but this active hurricane season
brought far to many reminders, including Dolly, Gustav and Ike.
Now that we have established that the hurricanes are coming
and since we have a pension for living, working and shopping on coastal areas,
maybe we should become more serious about protecting roofs in high-velocity
wind areas. After the levy’s held during Gustav, I kept hearing about great
American ingenuity. It is now time to put those resources to work for roofs. We
can’t save every roof in a hurricane, particularly if there is structural
damage to the building, but Hurricane Wilma in 2005 showed that regulated
precautions do help.
The steps to implement in high velocity wind regions are as
1. Require proper wind engineering calculations to determine
proper roof attachment methods.
2. Require perimeter roof calculations to determine proper
perimeter attachment methods.
3. Make certain that all roofing materials are tested for
wind uplift and have design pressures.
4. Municipalities should require progress inspections and
in-place attachment testing
These steps, which are all required in the IBC - once
enforced - could eliminate millions of dollars in annual roof damage.
