Hip Roof Wind Resistance

The most common roof shapes for homes tend to be.

Hip roof wind resistance.

If your home has a gable roof two sided pitched roof the end wall takes a beating during a hurricane and typical framing methods create a vulnerable hinge line at the joint between levels. At least 35 degrees from horizontal or steeper in slope is preferred. The nailing method used to install the shingles the quality and strength of the fasteners and the installation temperature can also play a role in the roof s ability to. Hip roofs have no large flat or slab sided ends to catch wind and are inherently much more stable than gable roofs.

This roof has slopes on all four sides and they come together at the top to form a ridge. Roofs with multiple slopes such as a hip roof 4 slopes perform better under wind forces than gable roofs 2 slopes. 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. However for a hurricane region the roof also has to be steep sloped.

Which roof shapes mitigate wind damage. Select appropriate wind and impact resistant roof coverings and install per the manufacturer s instructions. Make sure that they meet the standards for wind resistance astm d 3161 enhanced or ul 2390 and impact resistance. Rated wind and impact resistant asphalt shingles and standing seam metal roofs are good choices for storm resistance.

They are sturdy roofs that are durable in high wind areas. High pitched gable roofs with wide overhangs are more susceptible to wind uplift whereas aerodynamic four sided hip roofs are more resistant to damage.
