Typhoon Resistant Roof Design

Typhoon resistant roof design.

24 to really make the roof typhoon resistant. 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. The design of the cyclonic home includes simple systems to reduce the local wind. A round or multiple sided home is more resistant to hurricane strength winds.

Because mid range slope roofs withstand strong winds better than steep roofs keep the roof pitch below 6 12 and greater than 4 12. The pressures above show the upward wind pressure on the 3 main types of roof. The round design allows the wind to blow around the home. Hurricane hugo has proven the strength of the shed roof.

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. It s more expensive but much more resistant to blown debris. Probably the most important part of a hurricane house is a reinforced roof.

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. Build a moderately pitched hip roof. A cat 5 hurricane proof log house is resistant to the winds up to 245 mph. A gable end roof is generally cheaper to build but less wind resistant than a hip style roof.

Design guidelines for hurricane resistant buildings. This can be illustrated in the diagram below from the whole building design guide organisation. 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.

Additionally you may find that the traditional triangle trussed roof is abandoned for a curved roof design. The outer siding of your home also needs to be an approved hurricane resistant material. 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. Hurricane resistant houses should use stronger plywood.

In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact.
