One of the biggest differences between a covered patio or deck and a pergola is the way they are supported. A covered structure is actually installed as an extension of your home, connecting directly to the outdoor wall nearest the patio or deck you wish to cover. In comparison, a pergola doesn’t attach to the house. It is an independently supported structure, providing shade to the area of your backyard you have chosen.
Another difference between the two is the overall look and design. Covered patios are truly an extension of your home. You can get really creative with the materials you choose to incorporate. Pergolas are beautiful and built entirely out of high quality wood in the design of your choosing. They are aesthetically pleasing and offer a foundation for climbing plants.
