For a basic garage ceiling, drywall is a simple, cheap material option. It's easy to nail to existing beams and can also serve as a base for other ceiling materials if you decide to upgrade. This addition to your garage ceiling, when finished and painted, can go a long way toward giving the space a completed feel.
Wood is an option for a garage ceiling if you're seeking a warm, luxurious feel for the space. You can opt for wood paneling, tiles or strips in a wide choice of types including oak, pine and maple. Choose bamboo for a durable, environmentally-friendly choice.
If you're looking for a cheap, quick material option to add a closed ceiling to your exposed wood trusses, plywood is your best bet. You can purchase pre-cut pieces and nail to either the top or bottom of the trusses. This also provides an option for a partial ceiling that is usable for storage.
Use siding such as tongue-and-groove for your garage ceiling. This material is designed for use on the outside of a house but provides a durable ceiling.
Metal ceiling tiles such as tin and copper add a touch of sophisticated elegance to a garage, perfect for one that houses antique automobiles. These tiles can be installed over a traditional drywall ceiling and either painted or left bare.
