Typhoon Resistant Roof Design

Regarding the material of the roof hurricane prone areas tend to use galvanized metal over shingle.

Typhoon resistant roof design.

In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. The breakaway theory has therefore become less applicable to shed. Many shed roofs of traditional design have survived the storm. A gable end roof is generally cheaper to build but less wind resistant than a hip style roof.

A round or multiple sided home is more resistant to hurricane strength winds. 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. A cat 5 hurricane proof log house is resistant to the winds up to 245 mph. Build a moderately pitched hip roof.

Because mid range slope roofs withstand strong winds better than steep roofs keep the roof pitch below 6 12 and greater than 4 12. It s more expensive but much more resistant to blown debris. Hurricane hugo has proven the strength of the shed roof. The outer siding of your home also needs to be an approved hurricane resistant material.

Probably the most important part of a hurricane house is a reinforced roof. 24 to really make the roof typhoon resistant.

This can be illustrated in the diagram below from the whole building design guide organisation. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact. Hip roofs with four slopes will perform better than gabled roofs with only two slopes. Design guidelines for hurricane resistant buildings.

Yet the glaring disadvantage comes from hurricanes or tropical storms that make landfall. The pressures above show the upward wind pressure on the 3 main types of roof.
