Strong Wind Wind Resistant Roof Design

Then make sure that ring shanked nails no more than 6 inches apart are used for fastening.

Strong wind wind resistant roof design. Photo courtesy of ricowi system attachment is the most critical element of roof design and application. Improper attachment results in the increased probability of wind. The main design feature that we identified was the hip roof design which unlike a gable roof has all sides slope downwards to the wall at a fairly gentle slope. Wind resistant roof design hip roofs four sided roof design are more aerodynamic and inherently more resistant to uplift forces of high wind than gable end and other roof designs.

Class g resist uplift at wind speeds up to 120 mph. For wind resistant building design a continuous load path is the best protection against strong winds. Class d resist uplift at wind speeds up to 90 mph. Order reprints no comments damage to this pensacola school building began at the perimeter edges.

A continuous load path ensures that when a load including uplift and lateral horizontal loads attacks a structure the load will move from the roof wall and other parts toward the foundation and into the ground. Class h resist uplift at wind speeds up to 150 mph. Astm d3161 class f and astm d7158 class h. A wind resistant roofing material won t help you very much if the decking system below isn t any good.

A hip roof performs better than any other roof structure when faced with enduring high winds.
