Gable - Drawbacks

Drawbacks

Gable end roofs are among the worst roof designs for hurricane regions. Not only do gable roofs easily peel off in hurricane winds, but according to one hurricane survival guide book, a gable end "catches wind like a sail." When wind flows over a gable roof it behaves much like a wing. Lift is created on the leeward side of the roof. The flatter the roof the more likely this will happen. Steep roofs tend to cause the wind to "stall" as it goes over the roof and breaks up the effect. The addition of a "vertical fin" to low pitched roofs will also help.
