Outdoor Pergola Roof Materials
Pergolas have been used in dwellings for centuries, classically, to add a shaded walkway, to link pavilions or to allow a sitting area which allows the breeze and sun to filter through. One of the most important part of this structure is the pergola roof. There is a variety of materials that may be used to a pergola roof. 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. The advantage of a metal pergola roof is that it can be adjusted to the exact size and shape of the structure. A choice of metals such as copper, aluminium or tin also helps to make an easy decision. Metals not only easy to cut and shape, they also provide excellent protection from the weather conditions. However, they also have some disadvantages such as disallowing light to enter the area or enabling the temperature to get too hot inside the area.
Another variation of the pergola roof includes using plastic or fiberglass roofs. 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.
