Call Dispatch: (210) 436-6775- A certified wind-rated garage door MUST carry a physical safety label or sticker containing design pressure values and wind-speed ratings.
- The safety sticker is typically located on the interior face of the bottom or second panel of your garage door.
- Windcode 1 (W1) doors feature heavy-gauge horizontal steel struts, 14-gauge tracks, and solid steel stem rollers, whereas non-rated doors have none of these.
As San Antonio enforces new building codes mandating Windcode 1 (W1) certification for all newly installed residential garage doors, homeowners are increasingly asking: *Is my current garage door actually wind-rated?* Under severe South Texas storms, an unreinforced garage door can buckle, allowing high-speed winds to tear the roof off your home. Fortunately, verifying your door's wind-load capabilities is straightforward if you know where to look. Here is the step-by-step guide to finding your Windcode sticker and inspecting the critical hardware that separates a wind-rated door from a standard system.
1. The Certification Sticker: Your Primary Proof of Compliance
Every legally compliant, factory-certified wind-load garage door is required to have a physical safety and engineering label permanently affixed to its interior. This sticker is your primary proof of certification for municipal building inspectors and insurance auditors.
**Where to look:** Walk inside your garage with the door fully closed. Inspect the interior face of the panels. The sticker is almost always located on the bottom-most panel or the second panel up from the ground. It can also be found on the side of the door panels near the end stiles or warning labels.
**What to read on the sticker:** The label will display key engineering metrics, including the manufacturer (e.g., Clopay®), the model number, and the specific wind velocity rating. For San Antonio's W1 mandate, look for a rating of **115 MPH (3-second gust wind speed)** and design pressures indicating both positive and negative wind loads (e.g., +14.0 / -16.0 PSF). If this sticker is missing, painted over, or entirely blank, your door is legally considered non-rated.
2. Strut Reinforcements: The Steel Backbone
If you look at the interior of your garage door, you can easily tell its structural integrity by checking for reinforcement struts.
3. Track Thickness & Bracket Strength: Anchoring to the Structure
The steel tracks on either side of your door guide its movement, but on a wind-rated system, they also act as structural anchors holding the door inside the building during a storm.
4. Rollers & Hinges: Hardened Components vs. Light-Duty Hardware
The small hardware components hold the entire door assembly together. Under extreme pressure, weak hinges and rollers will fail, causing the door panels to separate.

Frequently Asked Questions: Emergency Response & Safety
Where is the Windcode certification sticker located on a garage door?
The manufacturing or Windcode certification label is placed on the inside face of the door panels, usually on the bottom-most panel, second panel, or near the warning labels on the side stile.
What wind speed is Windcode 1 (W1) rated for in San Antonio?
Under current San Antonio building mandates, a Windcode 1 (W1) rated door is certified to withstand design wind speeds of up to 115 MPH, ensuring the structure can resist severe storms without collapsing.
Can I just add steel struts to make my existing door wind-rated?
No. A wind-rated door is a complete, factory-tested system. Simply adding aftermarket struts to a non-rated door without the reinforced 14-gauge tracks, heavy-duty hinges, and approved spring balance will not meet building code compliance or qualify for insurance discounts.
