Typhoon resistant roof design.

The standard metal roofing thickness is now 26 gauges but some structural engineers now recommend a thicker sheet of ga. It s more expensive but much more resistant to blown debris. Regarding the material of the roof hurricane prone areas tend to use galvanized metal over shingle. Hip roofs with four slopes will perform better than gabled roofs with only two slopes.

Additionally you may find that the traditional triangle trussed roof is abandoned for a curved roof design. Following are path s recommendations for achieving storm resistant roofing. The design of the cyclonic home includes simple systems to reduce the local wind. That is to say that conceptually the shed roof would be blown away and the main roof would stay intact.

Hurricane resistant houses should use stronger plywood. Because mid range slope roofs withstand strong winds better than steep roofs keep the roof pitch below 6 12 and greater than 4 12. Hurricane hugo has proven the strength of the shed roof. The round design allows the wind to blow around the home.

Build a moderately pitched hip roof. A cat 5 hurricane proof log house is resistant to the winds up to 245 mph.

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.
