Two of the more popular types of doors are sectional roll downs and tilt-ups. Many styles, like the carriage house door, are available at much higher prices. Roll downs are traditionally more convenient in most situations but tilt-ups are usually much less expensive. Most styles are available in aluminum and steel. Aluminum is lightweight and won't rust. The major drawback to aluminum doors is that they can be easily dented. For a comparison between steel and aluminum doors call us at 386-643-4588.
