In building this kind of embellishment the roof is very important because it will define what specific type of pergola you are going to build. A Pergola roof is important because it will hold the plant above the ground which is the usual purpose of pergolas. As a permanent architectural piece to a garden pergola designs have evolved throughout the centuries making it more appropriate for gardens and environmental designs. During medieval and renaissance period pergola designs were used by people making curve segments incorporated with green vines. It was usually seen in gardens of Lords living in fortresses.
Plastic and Fibreglass Another variation of roofing for pergolas includes using plastic or fibreglass. The advantage of these options is that they are lightweight and inexpensive. They may also be easily cut to size and allows the light to filter in depending on the colour of the roof. They also protect the pergola from the harsher elements of the weather including the rain and snow. Also ultraviolet radiation may be reduced when using these two options. Although plastic may not be a green choice Fibreglass can be manufactured from recycled materials.
