Hurricane Garage Doors

Hurricane Garage DoorsAll hurricanes are dangerous, but some are more so than others. The way storm surge, wind, and other factors combined determines the hurricane’s destructive power.

The Saffir-Simpson Hurricane Scale is a 1-5 rating based on the hurricane’s present intensity. This is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall. Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf in the landfall region. Note that all winds are using the U.S. 1-minute average.

CAT 5 Hurricane Categories
  1. Winds 74-95 mph (64-82 kt or 119-153 kph). Storm surge generally 4-5 feet above normal. No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage to poorly constructed signs. Also, some coastal road flooding and minor pier damage.
  2. Winds 96-110 mph (83-95 kt or 154-177 kph). Storm surge generally 6-8 feet above normal. Some roofing material, door, and window damage of buildings. Considerable damage to shrubbery and trees with some trees blown down. Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the hurricane center. Small craft in unprotected anchorages break moorings.
  3. Winds 111-130 mph (96-113 kt or 178-209 kph). Storm surge generally 9-12 feet above normal. Some structural damage to small residences and utility buildings with a minor amount of curtain wall failures. Damage to shrubbery and trees with foliage blown off trees and large tress blown down. Mobile homes and poorly constructed signs are destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane center. Flooding near the coast destroys smaller structures with larger structures damaged by battering of floating debris. Terrain continuously lower than 5 feet above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation of low-lying residences with several blocks of the shoreline may be required.
  4. Winds 131-155 mph (114-135 kt or 210-249 kph). Storm surge generally 13-18 feet above normal. More extensive curtain wall failures with some complete roof structure failures on small residences. Shrubs, trees, and all signs are blown down. Complete destruction of mobile homes. Extensive damage to doors and windows. Low-lying escape routes may be cut by rising water 3-5 hours before arrival of the hurricane center. Major damage to lower floors of structures near the shore. Terrain lower than 10 ft above sea level may be flooded requiring massive evacuation of residential areas as far inland as 6 miles (10 km). Hurricane Luis of 1995 was a Category Four hurricane while moving over the Leeward Islands.
  5. Winds greater than 155 mph (135 kt or 249 kph). Storm surge generally greater than 18 feet above normal. Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane center. Major damage to lower floors of all structures located less than 15 feet above sea level and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the shoreline may be required. Source

The garage door is potentially the weakest point of your home during a hurricane. The door has a large surface area and the attachments on most garage doors are minimal – namely the track and wheels. Hurricane force winds can blow your garage door in or suck it out. Once hurricane force winds have entered the house, you are much more likely to lead to a buildup of internal pressure resulting in a loss of the roof or walls. According to the Federal Alliance for Safe Homes about 80 percent of residential hurricane wind damage starts with wind entry through garage doors, so protecting the garage doors is important.

You can check your current garage door for a sticker that gives the Miami-Dade seal, wind speed rating or pressure rating. Some older doors are rated to 100 mph winds, newer doors that are Miami-Dade County approved are rated to 150-165 mph.

For an existing home there are several options available to improve the durability of your garage: strengthening your current garage door or replacing it with a new model.

Prior to 1993 many garage doors were rated only to 50 mph. After 1993, many may be rated only to 100 mph.
