Typhoon Resistant Roof Design
Roof overhangs are subject to wind uplift forces which could trigger a roof failure.
Typhoon resistant roof design. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact. Hurricane resistant houses should use stronger plywood. Optimum roof pitch 6 12 for wind deflection and reduced lift. Although it can be dented by flying debris or hail the metal roof will withstand hurricane force winds and rain.
A gable end roof is generally cheaper to build but less wind resistant than a hip style roof. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. Lahouse features three types of hurricane resistant roofs each designed to withstand at least 130 mph winds. Many shed roofs of traditional design have survived the storm.
24 to really make the roof typhoon resistant. For example you might find that the roofs in hurricane prone areas are multi sloped. Yet the glaring disadvantage comes from hurricanes or tropical storms that make landfall. The standard metal roofing thickness is now 26 gauges but some structural engineers now recommend a thicker sheet of ga.
Hip roofs with four slopes will perform better than gabled roofs with only two slopes. The pressures above show the upward wind pressure on the 3 main types of roof. The outer siding of your home also needs to be an approved hurricane resistant material. Half the roof will use snap lock standing seam metal roofing.
It s more expensive but much more resistant to blown debris. Hurricane mitigation adequate roof protection is a must for coastal living seaside property aka coastal living has long been coveted for its fantastic views and access to beaches. The breakaway theory has therefore become less applicable to shed. Probably the most important part of a hurricane house is a reinforced roof.
This can be illustrated in the diagram below from the whole building design guide organisation. To see more images of some of our homes after hurricanes visit our galleries. Wind can t build up enough pressure on any. Hurricane hugo has proven the strength of the shed roof.
Our hurricane resistant design will perform far better than conventional construction.
