Hurricane Proof Wind Resistant Roof Design

Design guidelines for hurricane resistant buildings.

Hurricane proof wind resistant roof design.

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. Nystrom s new hurricane hatch is ideal for regions with extreme wind conditions. 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. 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.

For example you might find that the roofs in hurricane prone areas are multi sloped. The design of the cyclonic home includes simple systems to reduce the local wind. Recently redesigned this scuttle provides access to rooftop areas. As category 4 hurricanes range from 130 to 156 mph metal materials provide some of the highest protection available.

Nystrom s hurricane hatch is the industry standard for roof hatches in hurricane prone regions. Most metal varieties come with a warranty offering defense against winds up to 140 mph. Pyramid hip roof hurricane proof roof design. This hatch was tested for wind uplift forced entry and air infiltration.

The breakaway theory has therefore become less applicable to shed roof design. In the design of the hurricane resistant home the length of these overhangs should be limited to 20 inches.
