The Regular style carport is the most economical of the three styles (Regular, Boxed Eave, & Vertical). The Regular style is the only one of the three roof styles that has a barn style roof, with rounded, overhanging edges. The roof metal is installed horizontally so that the ridges of the metal run from the front of the carport to the back. As a result, water will drain off the front or rear of the building, since that’s the way the ridges run.
