Hip Roof Wind Resistance

This roof has slopes on all four sides and they come together at the top to form a ridge.

Hip roof wind resistance.

Roofs with multiple slopes such as a hip roof 4 slopes perform better under wind forces than gable roofs 2 slopes. Rated wind and impact resistant asphalt shingles and standing seam metal roofs are good choices for storm resistance. Select appropriate wind and impact resistant roof coverings and install per the manufacturer s instructions. 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.

Make sure that they meet the standards for wind resistance astm d 3161 enhanced or ul 2390 and impact resistance. The most common roof shapes for homes tend to be. High pitched gable roofs with wide overhangs are more susceptible to wind uplift whereas aerodynamic four sided hip roofs are more resistant to damage. At least 35 degrees from horizontal or steeper in slope is preferred.

This is a peaked triangular roof that allows for attic space or vaulted ceilings. However for a hurricane region the roof also has to be steep sloped. 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. Which roof shapes mitigate wind damage.

Hip roofs are thus much more resistant to wind damage than gable roofs. Gable roofs are generally more common because they are cheaper to build.
