A hammer drill, some quick drying epoxy and anchoring bolts are the tools you’ll need. Several types of materials can be used to build your pergola. Pressure-treated pine will hold up against the elements, but also can be heavy and difficult to use. Cedar and redwood are natural woods that resist decay, are easy to work with and age to a pleasing gray color. Mahogany is a tight-grained hardwood that resists pests and rot. When treated with marine oil, it has the appearance of teak. You can also use composite materials, which hold up well and are virtually maintenance free.
