Typhoon Proof Roof Design

This can be illustrated in the diagram below from the whole building design guide organisation.

Typhoon proof roof design.

Many shed roofs of traditional design have survived the storm. A round or multiple sided home is more resistant to hurricane strength winds. A gable end roof is generally cheaper to build but less wind resistant than a hip style roof. In addition to stronger materials below the roof hurricane prone areas design the roofing system differently than buildings which are not in high risk areas.

Hurricane resistant houses should use stronger plywood. For example you might find that the roofs in hurricane prone areas are multi sloped. It s more expensive but much more resistant to blown debris. The pressures above show the upward wind pressure on the 3 main types of roof.

Roof overhangs are subject to wind uplift forces which could trigger a roof failure. Design guidelines for hurricane resistant buildings. 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. Hurricane hugo has proven the strength of the shed roof.

Probably the most important part of a hurricane house is a reinforced roof. Hip roofs with four slopes will perform better than gabled roofs with only two slopes. The breakaway theory has therefore become less applicable to shed. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact.

The round design allows the wind to blow around the home.
