Hurricane Proof Wind Resistant Roof Design

For example you might find that the roofs in hurricane prone areas are multi sloped.

Hurricane proof wind resistant roof design.

Four sloping sides of the roof provided minimal resistance to the wind and allowed the wind to blow over and around the roof regardless of wind direction. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. Design guidelines for hurricane resistant buildings. 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.

Nystrom s new hurricane hatch is ideal for regions with extreme wind conditions. As category 4 hurricanes range from 130 to 156 mph metal materials provide some of the highest protection available. Pyramid hip roof hurricane proof roof design. The design of the cyclonic home includes simple systems to reduce the local wind.

A pyramid hip roof corresponds an easy hip roof however the wall surfaces are square as opposed to rectangle shaped making the form of the structure is roof incline involved a factor in a pyramid form on top. This hatch was tested for wind uplift forced entry and air infiltration. Hip roofs with four slopes will perform better than gabled roofs with only two slopes. Nystrom s hurricane hatch is the industry standard for roof hatches in hurricane prone regions.

Metal roofing is generally considered the best option for hurricane resistance. The breakaway theory has therefore become less applicable to shed roof design.
