Pergolas provide shade, which can drop the temperature of your house and backyard during those hot summer days. In addition to being aesthetically pleasing, and creating a comfortable feeling for your backyard, they add the smell of cedar or fir for years after construction, especially after a rain. Patio covers provide UV exposure, and waterproof areas for extra functionality. Most common on a two story exterior wall with nothing but windows and vents, these roofs can easily involve beautiful ceilings like pine tongue and groove, or the classic soffit, and can even include ceiling fans and lighting to make the space even more comfortable. Want some inexpensive added beauty and uniqueness to your backyard? Pergola. Tired of shoveling snow off your back door? Patio cover.
