The design of a pergola depends on the geographical location. Depending on the area, the grade or the direction of the sun, a pergola may be a gazebo, an extension of a building, an open terrace or a veranda that has grapevines criss-crossing a latticed roof. One of the most important considerations when designing a pergola is the roofing structure and shape The roof design on a pergola depends on the availability of direct sunlight as well as the geography and natural features of the region. Although, in earlier times, pergolas were constructed using brick and stone pillars, modern designs employ weather resistant woods such as western red cedar or coast redwood. Pergola roofs may range from simple, flat, traditional roof, elaborately curved roof, pitched roof, gabled roof or a gazebo style roof.
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.
Metal Roof The advantage of a metal 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.
