GARAGE DOORS INVITE WIND DURING HURRICANE SEASON

Hurrican Rated Garage Doors HoustonIn high wind storms, garage doors buckle in the middle, rollers pop out of brackets and the door fails. If the pressure from hurricane force winds batter down your garage door, the pressure then builds inside your home trying to find a way out. This usually results in forcing the roof off of your home causing catastrophic structural damage.   On the plus side, horizontal and vertical struts, rollers and brackets can strengthen the door and transfer the wind load across the door to the garage structure. Unless your doors have been installed after new building codes in 2002, your home may be threatened. Retrofitting and new doors are options to consider.

NEW GARAGE DOORS HOUSTON. First, look at your existing door. If it was installed after the new building codes went into effect on March 1, 2002, it should meet the requirements for wind load in your area. A label or certification seal on the door will indicate this.

If it’s an older door, or it’s a builder grade door, you can have a new door installed that meets hurricane codes. The requirements vary depending on which wind zone you’re in. Preferred Doors can help you determine which door is right for where you live. A door must withstand higher wind load along the beaches (and therefore will cost more) than one that’s installed in inland Harris County.

There is one thing to keep in mind; the strongest door in the world won’t help if the garage is flimsily constructed.

RETROFITTING EXISTING DOORS. Retrofitting an existing door involves strengthening the panels, tracks and rollers to withstand the wind – what a new door would do. Garage door repair companies in Houston Texas can do this for you, or you may be able to find a retrofit kit that you can install or have someone install for you.

When high winds swirl around the house, they exert both pressure and suction on that big expanse of door, which is held in place only by the tracks. So your goal is to reinforce the door and the tracks. You don’t want the door to be sucked out of the tracks, and you don’t want the tracks to pull out of the ceiling or wall to which they’re attached.

Retrofitting involves giving doors rigidity against pressure and suction. U-shaped metal struts or bracing attach horizontally and vertically onto each panel of the door. But bracing the door is only part of the task.

Preferred Doors recommends adding long stem rollers with the hold in clips. The shaft, or stem, on the roller is longer so that if the door does flex in high winds, the roller won’t pop out of the hinge. The clip also helps the roller from coming out.

We also recommends adding 2×6’s anchored to the frame work around the garage door so the vertical track and jamb brackets won’t give way. Most of the time this is required for certification.

Adding struts, reinforcing the track, replacing the rollers and recalibrating the springs would certainly help in hurricane force wind storm.

You may decide that the cost of retrofitting an existing door would be better applied toward the price of a new door.

Garage door springs contain a huge amount of stored energy. An out-of-control spring can be dangerous or even deadly. This is one of those jobs that may best be left to the experts. Simply attaching plywood to the inside of the door may void the warranty or damage the motor or the track because the door is too heavy to operate properly.

The trade association for garage door manufacturers issues this caution: “Owners should avoid adding reinforcement to a garage door themselves. This will increase the weight of the door and may result in failure or collapse of the supporting tracks or other components that may not be suitable to carry the extra weight. Upgrading garage doors by adding reinforcement must be performed as a package that includes appropriate springs and hardware and supporting track.”

There are also removable posts that can be attached to a plate in the garage floor and to a header above the door. When a storm is about to make landfall, someone has to be available to put the post in place and run cables from the door to the post to prevent the door from flexing.

Don’t neglect the greatest openings in your home. More aged garage doors had been made out of thinner gauge products that could flex under stress wind pressure and push the garage door outside of its tracks. As soon as the garage door opening is affected, your house will become vulnerable to blowing wind damage and water flooding. To stand up to the effects and excessive pressures of hurricane force wind gusts, wind load rated garage doors are manufactured and tested to satisfy and meet or exceed state and county building codes.

Older, traditional garage doors can be replaced with Hurricane Garage Doors and it would be cost-effective. The structure that meets the wind load standards can be retrofitted in to the current garage door system, but an entire replacement unit is usually recommended. One of the prime reasons for this is that Wind Load Hurricane Garage Doors usually require much heavier vertical stiles and extra horizontal reinforcement. Which implies that the units springing weight will have to be changed, that will then require new springs; the track; the track attachments; the hinges and the rollers also to be replaced to properly transfer the wind loads with the door towards the building.


Garage Door Springs

Garage Door Spring Systems is the Most Used Commonly on Sectional Type Overhead Doors.

Garage doors are very heavy and some type springing systems must used at the top with cables attaching to the bottom garage doors to counterbalance the weight of the door. When a garage door is opened, these springs assist in lightening the weight of the door. When closing the door, the springs keep it from slamming hard on the ground and damaging the door or causing injury.

 

To release the spring tension, raise the door in the fully open and clamp the door into position using a pair of vice grips in the tracks to prevent the door from moving.  Once the door is open, you can make spring adjustments to only the extension spring type systems.

 

Torsion spring systems adjustments are not recommended by the do it yourselfer.
Typically overhead garage door springs have a life expectancy of 10,000 cycles, unless you special ordered your door with extended life cycle springs. One cycle is an operation of an up and down.  The extension and torsion springs are tempered (hardened) steel that comes either in plain cold rolled, painted, oil soaked, or galvanized. When the garage door is closed these springs are under very extreme tension and can be dangerous causing injury.

 

Over time, or during the later stages of the life cycles, springs will start to fatigue, and will eventually start stretching and or breaking, usually releasing its spring load with loud bang. Most homeowners, if you are at home, hear the spring break and usually unable to find where the noise came from until you try to use your garage door the next time.

 

On the average I see a 10k life cycle spring last around 7 to 10 years depending on how often you use your door.  Anything over 10 years is a bonus.  For example, if you average about two cycles per day, opening and closing the door a total of 4 times as you come and go, then the life expectancy becomes 2500 days, or approximately 7 years. If you have children that drive or more adults with vehicles, then you tend to cycle the door even more often, which in turn needing a spring replacement even sooner.

Since standard lift torsion springs are winding “up” when the door is closing or going down, the fully closed position is the most stressful on the steel spring material and thus the most likely the time of breakage. This is a good thing; because failure near the top-of-travel means that you suddenly have a large heavy door coming down and crashing against the floor with the increased weight. As a rule of thumb, and for safety reasons, you should never be standing or walking under the door when it is opening or closing, especially if you do so manually instead of with an electric opener. Also automatic door operators will provide additional safety if and when the spring breaks during the door movement.

When the springs are working correctly, the door appears nearly weightless, but this is an illusion that turns into a calamity when the springs suddenly fail.

Caution:  If you need to make annual adjustments to the springs or repair the door, we recommend using a trained garage door technician to do your annual tune-ups.

NOAA Expects Busy Atlantic Hurricane Season

Posted on by Preferred Doors in WindLoad Leave a comment

May 27, 2010

An “active to extremely active” hurricane season is expected for the Atlantic Basin this year according to the seasonal outlook issued today by NOAA’s Climate Prediction Center – a division of the National Weather Service. As with every hurricane season, this outlook underscores the importance of having a hurricane preparedness plan in place.

Across the entire Atlantic Basin for the six-month season, which begins June 1, NOAA is projecting a 70 percent probability of the following ranges:

  • 14 to 23 Named Storms (top winds of 39 mph or higher), including:
  • 8 to 14 Hurricanes (top winds of 74 mph or higher), of which:
  • 3 to 7 could be Major Hurricanes (Category 3, 4 or 5; winds of at least 111 mph)

“If this outlook holds true, this season could be one of the more active on record,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator. “The greater likelihood of storms brings an increased risk of a landfall. In short, we urge everyone to be prepared.” Read more
