Typhoon Resistant Roof Design

24 to really make the roof typhoon resistant.

Typhoon resistant roof design.

Build a moderately pitched hip roof. The design of the cyclonic home includes simple systems to reduce the local wind. The breakaway theory has therefore become less applicable to shed. Yet the glaring disadvantage comes from hurricanes or tropical storms that make landfall.

Hip roofs with four slopes will perform better than gabled roofs with only two slopes. The outer siding of your home also needs to be an approved hurricane resistant material. The round design allows the wind to blow around the home. Following are path s recommendations for achieving storm resistant roofing.

Hurricane hugo has proven the strength of the shed roof. The pressures above show the upward wind pressure on the 3 main types of roof. 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. Many shed roofs of traditional design have survived the storm.

Because mid range slope roofs withstand strong winds better than steep roofs keep the roof pitch below 6 12 and greater than 4 12. Probably the most important part of a hurricane house is a reinforced roof. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. The standard metal roofing thickness is now 26 gauges but some structural engineers now recommend a thicker sheet of ga.

Additionally you may find that the traditional triangle trussed roof is abandoned for a curved roof design. One effective strategy to protect the house occupants from very strong typhoons is by providing a concrete slab just above the room or if the family can afford the entire house. Hurricane resistant houses should use stronger plywood. Wall logs in such construction have to be made of circular reference glued laminated timber and all other components of the house have to be hurricane resistant.

That is to say that conceptually the shed roof would be blown away and the main roof would stay intact. A round or multiple sided home is more resistant to hurricane strength winds. A cat 5 hurricane proof log house is resistant to the winds up to 245 mph. It s more expensive but much more resistant to blown debris.

A 4 sided roof is more typhoon resistant because it gives wind less traction to pry the roof away a horrific phenomenon witnessed by people living in houses with two sided roofs during the storm. Regarding the material of the roof hurricane prone areas tend to use galvanized metal over shingle.
