Here in Nebraska, we’re no strangers to strong winds and severe storms. Between that and the recent derecho in Iowa, we’re finding that many people in our area (and across the country) have this question front of mind: How will my garage door hold up against strong winds?
Most garage doors are built durable enough to withstand the elements; however, you can also increase your door’s wind load capabilities for an added peace of mind. Increasing the wind load involves the use of added reinforcements to make the door stronger and even more durable in the face of the elements. Certain areas that are more prone to strong winds, such as Florida, have requirements and codes in place for the wind load of garage doors. While we do not have these mandates in our area, we believe it’s better to be safe than sorry.
When it comes to determining the ideal wind load of you garage door, there are a number of factors to consider. According to Clopay, an industry leading manufacturer of wind loaded doors, figuring out your design pressure and WindCode rating is as simple as these 4 steps:
Step 1: Determine the minimum wind speed in MPH doors must meet or exceed for your area. You can check with your local building code official to find out the requirements for your specific area or look up your requirements online through ATC’s website: www.atcouncil.org/windspeed
Step 2: Determine the exposure type of your region. This is typically described as Exposure B (urban or suburban setting or wooden terrain) or Exposure C (open terrain with scattered obstructions, flat open ground, grasslands or shorelines in hurricane-prone regions).
Step 3: Determine the structural type of your home: one story or two story.
Step 4: Using your wind speed (MPH), exposure type, and structural type, calculate your design pressure and WindCode “W” rating, which a garage door pro will be able to help you accomplish according to Clopay’s guide.
Different combinations of these factors result in varying levels of susceptibility to the effects of strong winds. For example, consider this scenario…You have a 2-story house located on top of a hill in an area that’s known to be relatively windy. Because of your home’s location, surroundings, and structure, it is more vulnerable to strong winds, so you’ll want to increase the wind load on your garage door to ensure it’s properly equipped to withstand the weather. You may even consider surpassing your minimal durability requirements for extra protection.
