Pergola / October 15, 2018 / JulietteHughes.
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. 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.
To paint a pergola for lasting protection it is important to follow the traditional procedures such as preparing the surface which include removing old paint using sandpaper to permit absorption and applying preservative towards the end of the painting. Preparation of the surface is very important before painting as it decides how much time the effect of painting will last. Any remnants of oil or dirt on the surface of the wood should be removed thoroughly. Using sand paper with 50-60 grit create an appropriate surface for good absorption of paint. If the wood is more than two weeks old or if it had been lying outside in rain sanding brushing and cleaning becomes essential.
The reason is pergolas are always sized based on their roof size. And in most cases pergolas are recessed back from the roof edge anywhere from 8 inches to a couple of feet depending on the design (commonly 12"). Custom design or sizing can be a good idea to get a suitable pergola for your place. Look for manufacturers that insist on shop drawings prior to building and take the time to check everything repeatedly and make sure that all measurement and details are agreed to in writing ahead of delivery time. Assembly required/Assembly Instructions: Make sure you have collected assembly instructions from the manufacturers.
