If you’re looking for a way to add a beautiful, yet functional, accent to your home, there’s no better way than with a pergola or louvered roof system. A pergola is an outdoor structure that is built onto your home. It has columns and a roof that can be open or completely closed. The possibilities for pergolas are endless. If you’re interested in adding one to your home, it is important to fully understand the type of construction you’re getting. The definition given by The Spruce is pergolas are “often attached to houses, such that they form an outdoor living space that essentially serves as an extension of a home’s indoor rooms”.
