Hip Roof Wind Resistance

However for a hurricane region the roof also has to be steep sloped.

Hip roof wind resistance.

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. Gable roofs are generally more common because they are cheaper to build. Make sure that they meet the standards for wind resistance astm d 3161 enhanced or ul 2390 and impact resistance. At least 35 degrees from horizontal or steeper in slope is preferred.

Hip roofs are thus much more resistant to wind damage than gable roofs. Select appropriate wind and impact resistant roof coverings and install per the manufacturer s instructions. Rated wind and impact resistant asphalt shingles and standing seam metal roofs are good choices for storm resistance. This roof has slopes on all four sides and they come together at the top to form a ridge.

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. High pitched gable roofs with wide overhangs are more susceptible to wind uplift whereas aerodynamic four sided hip roofs are more resistant to damage. Hip roofs have no large flat or slab sided ends to catch wind and are inherently much more stable than gable roofs.

Roofs with multiple slopes such as a hip roof 4 slopes perform better under wind forces than gable roofs 2 slopes. This is a peaked triangular roof that allows for attic space or vaulted ceilings.
