Choose the right material ii) Go for thicker structures iii) Notching and Hardware iv) Do not ignore your local weather v) Get details of manufacturers warranty vi) Reduce sizing errors to zero vii) Amount of Assembly Required Right Material: Ensure that you have chosen a pergola that will continue to look beautiful for ten years or more. The right choice of material is a key point. Most arched pergolas are built from Wood Steel/Aluminum Concrete or PVC/Vinyl. Among them wood is the most reliable and popular material. However given a vast array of wood types which include California Redwood Teak Cedar and Imported Hardwoods among others buyers easily can get confused as to which of them would be best for their situation.
So while buying wooden pergolas ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergolas timbers has hidden stresses in it (quite common) as it weathers over the years it will turn twist or sag.
Depending on the type of fabric used these pergolas may avoid the transmission of heat which could cause fading or damages to the roof. A tough and durable fabric that may usually be used in the making of the sails of a boat can also be used to filter ultraviolet rays and other harmful natural elements such as sunlight and heavy rain so that people can enjoy their investment for a long time.
