Strong Wind Wind Resistant Roof Design

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

Strong wind wind resistant roof design.

For wind resistant building design a continuous load path is the best protection against strong winds.

When having a new roof installed make sure that rotted or damp wood is removed and that particleboard is replaced with stronger heavier plywood. Then make sure that ring shanked nails no more than 6 inches apart are used for fastening.

Astm d3161 class f and astm d7158 class h. 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. A wind resistant roofing material won t help you very much if the decking system below isn t any good. Improper attachment results in the increased probability of wind.

Roof design for proper wind resistance. Class h resist uplift at wind speeds up to 150 mph. 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 d resist uplift at wind speeds up to 90 mph.
