According to a study conducted by Civil Engineer Rima Taher, PhD, a special lecturer at New Jersey Institute of Technology (NJIT) School of Architecture, some home shapes and roof types are able to resist high winds and hurricanes better. This was determined after two years of using the best designs as well as construction materials and methods that can test extreme wind events and hurricanes.
As part of the study, Taher’s team created a prototype of a hurricane-resistant property. The design had a hip roof and had a central shaft installed. It has an aerodynamic feature that minimizes wind forces during extreme wind events. The test results showed that this kind of home can withstand high winds and hurricane conditions compared to other kinds of structure. Taher also provided some recommendations to consider for homeowners living in hurricane-prone areas:
Consider having a floor plan that is in a square, hexagonal or octagonal outline with panel roofs of four or more. The result of Taher’s study showed that properties with this kind of plan can help reduce wind loads.
While gable roofs (two panels) are cheaper, it’s better to go for hip roofs (four panels) since they perform better under wind forces.
Ask for a gutter installation service to have a notched frieze or a horizontal grid placed at the level of the gutters within the perimeter of the home.
Structural connections are one of the biggest factors that can help prevent wind damage. Consider connecting roofs to walls but be sure that this is done properly.
Wind Mitigation Principles
It is possible to make your existing roof become wind resistant as well. This roof repair work can be more expensive but it can be done. Here are some recommendations:
Reinforcing of gabled roofs to prevent the gable from connecting to the wall line.
Inspect the underside of decking to check whether or not there are deck nails that have missed the rafters and trusses.
Before reroofing, rafters and trusses should be installed. Proper alignment with the studs is required so that the rafters and trusses will be strapped to the studs.
Check the installation of veneered or sided chimneys. If not installed properly, this can still be corrected. Proper roof flashing installation around the chimney also helps prevent leaks.
