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.

The most common roof shapes for homes tend to be. Roofs with multiple slopes such as a hip roof 4 slopes perform better under wind forces than gable roofs 2 slopes. 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. 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. Hip roofs are thus much more resistant to wind damage than gable roofs. 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.

Make sure that they meet the standards for wind resistance astm d 3161 enhanced or ul 2390 and impact 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. However for a hurricane region the roof also has to be steep sloped. Rated wind and impact resistant asphalt shingles and standing seam metal roofs are good choices for storm resistance.

Which roof shapes mitigate wind damage. Gable roofs are generally more common because they are cheaper to build.
