  1. Roofing is not just used for protection, though. It is one of the most important aesthetic features of the whole pergola and it can transform it from drab to fabulous.  You could choose for a simple flat roof, or pitched roofs, gable and multi gable roofs, or even elaborate curved roofs, depending on what you are trying to achieve.
