The National Hurricane Preparedness Week runs from May 5 to 11 this year, and it’s a timely reminder to assess and upgrade your home’s defenses. Hurricanes are a disastrous part of life, and homeowners in vulnerable regions are reminded of the importance of securing their homes against the devastating impact of these powerful storms. A critical yet often overlooked aspect of hurricane preparedness is ensuring that garage doors are capable of withstanding high winds and flying debris. There are several ways of preparing your garage door for hurricanes, and one of them is by using wind-load rated garage doors.
Importance of National Hurricane Preparedness Week
National Hurricane Preparedness Week serves as an annual reminder for individuals and communities to review and improve their preparedness plans. It emphasizes the importance of taking proactive steps to protect lives and property before a hurricane strikes. During this week, homeowners are encouraged to inspect their homes, including garage doors, to ensure they are fortified against potential hurricanes. It’s an opportune time to consider upgrades, perform maintenance, and educate oneself on the necessary precautions for the upcoming hurricane season.
Wind-Load Rated Garage Doors
Wind-load rated garage doors are specifically designed and tested to withstand high-wind pressures during hurricanes and severe storms. These doors are constructed with reinforced materials and have additional bracing and heavier gauge tracking to resist bending and breaking under extreme wind conditions. The rating of a wind-load door indicates the level of wind speed it can endure, measured in miles per hour (mph).
Wind-load ratings for garage doors are determined based on testing and standards set by the American Society of Civil Engineers (ASCE) and local building codes. The higher the rating, the stronger the door’s resistance to wind forces. Ratings are typically aligned with the expected wind speeds in different geographic zones, from moderate wind areas to those prone to extreme hurricanes.
Wind-Load Rating Values Explained
1. Moderate Wind Load (90-130 mph)
Doors rated for moderate wind loads are designed for areas where hurricanes are less frequent but where storms and strong winds can still occur. These doors can typically withstand wind speeds of 90 to 130 miles per hour, equivalent to the wind forces generated by a Category 2 or 3 hurricane. They are suitable for regions that are not directly on the coast but may still experience significant wind events.
2. High Wind Load (131-150 mph)
High wind load ratings are intended for areas that may experience more severe hurricane conditions. Doors with this rating can endure wind speeds of 131 to 150 miles per hour, aligning with a Category 4 hurricane’s intensity. These doors are recommended for homes in regions closer to the coast, where the risk of more powerful storms is higher.
3. Extreme Wind Load (Over 150 mph)
Extreme wind load rated doors are the strongest available, designed to withstand winds exceeding 150 miles per hour. These doors are engineered for the highest-risk areas, such as those that could be impacted by a Category 5 hurricane. With reinforced materials and construction, these doors offer the maximum level of protection against the most powerful and destructive storms.
Is My Garage Door Wind-Rated?
Do you see sticker labels on the interior of your door that list values such as MPH, PSF+, and PSF-? This means your garage door has a wind rating. The MPH value refers to the velocity of wind the door can withstand, while PSF (pounds per square foot) measures the wind’s force against the door.
Preparing Your Garage Doors for Hurricanes
1. Assess Your Current Garage Door
Begin by assessing the structural integrity and wind resistance of your current garage door. Look for any signs of wear, corrosion, or damage that could compromise its strength. If your door is old or does not meet the wind-load requirements of your area, it may be time for an upgrade.
2. Choose the Right Wind-Load Rated Door
When selecting a new garage door, ensure it is wind-load rated to withstand the specific wind speeds expected in your area. Manufacturers provide detailed specifications and ratings for their doors. Consult with a professional garage door installer who is familiar with local building codes and can recommend the appropriate level of protection.
3. Installation by Professionals
Proper installation is key to ensuring that your wind-load rated garage door performs as expected during a hurricane. It’s recommended to have your door installed by certified professionals who are experienced in working with wind-load systems. Incorrect installation can lead to vulnerabilities and potentially catastrophic failure during a storm.
4. Regular Maintenance
Regular maintenance is essential to keep your garage door in optimal condition. Check the door and its components (springs, hinges, rollers) for any signs of wear or damage. Ensure that the door seals tightly and that there are no gaps for wind to enter. Schedule an annual inspection with a professional to ensure your door maintains its structural integrity.

5. Consider Additional Reinforcements
In some cases, additional reinforcements may be necessary, especially if you live in an area with extremely high wind-speed risks. Retrofit kits are available that can further strengthen your garage door against wind pressure and impact from debris.
As we approach National Hurricane Preparedness Week, it’s a critical time to focus on securing one of the largest openings in your home: the garage door. Upgrading to a wind-load rated garage door is a significant step towards protecting your property and loved ones from the ravages of hurricanes. By assessing your current door, choosing the right upgrade, ensuring professional installation, and maintaining your door’s condition, you can greatly enhance your home’s resilience to these powerful storms. Remember, preparation today can prevent devastation tomorrow.
