“The archetypical Bermuda house is a low, squared building with a stepped, white roof and pastel-painted walls, both of which are made out of stone. The roofs are designed to catch water, of which there is no fresh supply in Bermuda apart from rain. The walls are designed to restrict damage from hurricanes and are required by law to be able to withstand windspeeds of over 100 mph (160 km/h).”
This Bermuda Roof Repair PDF shows a lot of construction details about traditional Bermuda roofs.
