Hurricane Proof Wind Resistant Roof Design

This hatch was tested for wind uplift forced entry and air infiltration.

Hurricane proof wind resistant roof design.

As category 4 hurricanes range from 130 to 156 mph metal materials provide some of the highest protection available. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches. Why else do owners choose metal roofs. Most metal varieties come with a warranty offering defense against winds up to 140 mph.

Hip roofs with four slopes will perform better than gabled roofs with only two slopes. 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 addition to stronger materials below the roof hurricane prone areas design the roofing system differently than buildings which are not in high risk areas. 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.

For example you might find that the roofs in hurricane prone areas are multi sloped. Recently redesigned this scuttle provides access to rooftop areas. Pyramid hip roof hurricane proof roof design. Metal roofing is generally considered the best option for hurricane resistance.

Nystrom s new hurricane hatch is ideal for regions with extreme wind conditions. The breakaway theory has therefore become less applicable to shed roof design.
