Strong wind wind resistant roof design.

Roof design for proper wind resistance. A hip roof performs better than any other roof structure when faced with enduring high winds. For wind resistant building design a continuous load path is the best protection against strong winds. 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.

Astm d3161 class f and astm d7158 class h. Asphalt roofing shingles in the market generally all carry the same wind resistance classifications. Class g resist uplift at wind speeds up to 120 mph. 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.

A wind resistant roofing material won t help you very much if the decking system below isn t any good. Then make sure that ring shanked nails no more than 6 inches apart are used for fastening. When having a new roof installed make sure that rotted or damp wood is removed and that particleboard is replaced with stronger heavier plywood.

Class d resist uplift at wind speeds up to 90 mph.
