Overhead doors are susceptible to freezing in cold weather. When water freezes, it expands and can cause the door to warp or become misshapen. In extreme cases, the door may even crack. To prevent your overhead door from freezing, you can take some simple steps:
-Apply weatherstripping around the door to seal off any gaps where cold air could enter.
-Install a threshold seal at the bottom of the door to keep out drafts.
-Consider adding a storm door or an insulated garage door opener.
-Keep your garage warm by insulation the walls and ceiling. You can also add a space heater to the garage, but be sure to keep it away from any flammable materials.
-If your overhead door does freeze, you can try thawing it out with a hairdryer or by applying heat directly to the frozen area with a portable heater. Never use an open flame to thaw out a frozen door, as this could damage the door or start a fire.
