Causes of Discoloration of Pergola roofs. Over time. Pergola roofs may get discoloration due to dirt. fungus. mildew or moisture. Also. any iron fittings may rust and cause red stains which may react with other pigments or stains. To prevent this. stainless steel nails may be used and a constant vigil kept to encourage the Pergola to stay dry. A commercial mildew remover or other multi-purpose cleaners and help keep the roof spotless. Stains that are caused by the reaction of water deposits on the wood may also be removed by washing it with cleaners. Chalking is another form of discoloration which is caused by weathering of paint or disintegrating of pigment particles. which appear as a powder. Restoration painting necessitates cleaning by paint strippers. bleachers and oxalic acid based solvents to remove stains.
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.
Avoid Sizing Errors: Since most Pergola buyers are one time buyers. many sizing errors are common. For example. a common mistake is to assume the positioning of the 4 corner posts is the size of the pergola being offered. For instance. if the four corner posts of a pergola are expected to sit on the corner of your brand new concrete pad that is 10` x 12`. and purchase a 10` x 12` pergola. you will discover on receiving your pergola kit that the posts are set at 8` x 10` to the outside corners. 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.
Manufacturer`s Warranty: Before buying an arched pergola. make sure that you can get replacement parts in future years even though your pergola is custom-designed. Look for pergola manufacturers that have been in the business for at least five years. The advantage of choosing such a manufacturer is that they can be more reliable in terms of fulfilling their product warranty or helping you with replacement parts at any time.
