Yes, roller garage doors require electric openers to operate. The door rolls up onto a barrel positioned above the opening. Motors are usually rated at either 1/2 horsepower or 3/4 horsepower and can be plugged into a 220-volt outlet or hardwired. Battery backup operation is available on some models in case of power outages.

Roller garage doors can be automated with the addition of accessories. Remote controls allow operation from within the car or outside the garage. Wall-mounted keypads provide keyless entry. Smartphone apps give control using a mobile device. These automated options are convenient and add security.

Roller doors are constructed from aluminum or steel horizontal slats that are extremely durable. The metals resist dents, bumps, and damage from impacts. The bending design of the panels allows them to withstand minor collisions and still operate properly. Proper maintenance helps maintain their durability for years.

Roller doors are well-suited for wide openings. Typical residential size limits are widths up to 16 feet and heights up to 10 feet. Larger commercial sizes are available up to widths of 22 feet and drops around 14 feet before guide tracks would be required. Their compact horizontal design makes roller doors ideal for wide, short openings.
