Pergola roofs may range from simple flat traditional roof elaborately curved roof pitched roof gabled roof or a gazebo style roof. Roofing materials There is a variety of materials that may be used to roof a pergola. The choice of roofing materials depend on the size shape and style of the structure. The durability and robustness of the construction depends on the materials that are selected for this purpose.
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. Polycarbonate Polycarbonates are thermoplastic polymers which can be easily moulded and has a high impact resistance along with other advantages such as heat resistance ease of shaping flame retardancy and toughness.
This does not mean that any type of pergola would be effective. Instead you will have to be careful of what kind of pergola designs you approve of for your garden. Consider the following. 1.
