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. Perhaps the most vulnerable area of the house during typhoon is the roof. 8 additionally with the roof and floors built using a radial truss array that allows any potential energy from sustained winds to disperse across the entire structure instead of building up in one area. Design guidelines for hurricane resistant buildings.

For example you might find that the roofs in hurricane prone areas are multi sloped. A round or multiple sided home is more resistant to hurricane strength winds. Hurricane resistant houses should use stronger plywood. How being proactive pays off.

Roof overhangs are subject to wind uplift forces which could trigger a roof failure. To know more about roof check out this 6 roof ideas for your home. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. Hurricane hugo has proven the strength of the shed roof.

All of these issues must be taken care of before hurricane season hits. The breakaway theory has therefore become less applicable to shed. It s more expensive but much more resistant to blown debris. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact.

To provide additional security for your roof install roof tie downs and anchors. Hip roofs with four slopes will perform better than gabled roofs with only two slopes. Probably the most important part of a hurricane house is a reinforced roof. A gable end roof is generally cheaper to build but less wind resistant than a hip style roof.

Even if you don t need a new roof completely they re certainly signs that an inspection is needed. 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. If you end up investing in a new metal roof resistant to hurricane damage you may reap more benefits than you initially realized. Once the roof is damaged or ripped off the interior of the entire house is exposed to wind rain and other matter.

6 7 the round design allows the wind to blow around the home reducing the build up of pressure on one side. 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.
