For a "roof" see following previous similar questions for ballpark numbers - for a free-standing gazebo or aluminum patio shed or flat roof typically in the $30-40/SF range installed in aluminum, more like $40-60/SF in conventional wood and shingle, sometimes cheaper with light-weight (so not as wind or snow load resistant) ones - down to as low as $5-10/SF for box store kit ones a couple of people can put up on their own.
