A carport is a covered structure used to offer limited protection to vehicles, primarily cars, from the elements. The structure can either be free standing or attached to a wall. Unlike most structures a carport does not have four walls, and usually has one or two. Carports offer less protection than garages but allow for more ventilation. They are also more versatile. With the recreational vehicle or RV gaining in popularity, so has the need for a structure that can cover and protect these modern, moving homes. Many find that a RV carport is the perfect solution. Some enterprising businesses have even expanded the uses of these structures by taking advantage of their versatility. The carport and shadeport industry has modernized quite a lot over time. It is no longer just a roof covering for a car or vehicle but has extended itself to leisure uses such as awnings for a patio at home or a more modern designer shade sail.
