Pergolas made of wood are the most cost-effective of all types of materials, though they are not as long lasting as vinyl or metal. The advantage of wood is that it gives a more natural appearance to pergolas and also can be stained or painted for a completely new look. The downsides of wood pergolas is that they can rot or splinter. Wood pergolas will also be affected by pests, further damaging the wood sooner than normal. But wood pergolas are easy do-it-yourself projects, so you won’t have to consult with professionals and there are many kits available to make the process even easier.
