Regular Roof Style frame is the true original metal “carport” which was introduced over 24 years ago. Regular frames have 5 bends which gives the curved roof appearance. They are the most economical types of buildings. The roof paneling is ran from front to back, which means rain water and debris must travel over each rib to fall off the sides or travel to either end. Annual maintenance is required. *NOTE: buildings 36′ and longer have a high potential to leak, we strongly recommend purchasing a vertical roof building for longer units.
