The same advantages can be applied to the above-ground levels of a house by using engineered roof trusses. The sophistication of these building elements has increased enormously as computer-aided design and manufacturing have entered the industry. Trusses are factory-assembled wooden frameworks that fit together on the walls of a house to form the roof. As with floors, modern roof trusses increase the amount of open floor space by reducing the need for support posts and load-bearing walls. They also allow complex, attractive roof profiles to be created quickly and easily on all building sites. Any reputable custom builder can offer various floor plans that include large-span engineered roof and floor systems.
