One of the protection structures that are most popular is a veranda roof that is simple. Its building can be rapid and economical. The kind of patio roof you choose determines how strong the framework must be and how far apart the rafters will be spaced.
If you need a lightweight, simple-to-install roof that accepts diffused sunlight, consider plastic shade cloth over rafters that are widely spaced. In most climates it is useful to soften sun on plants than to provide shade for individuals. You may have noticed shade fabric used at nurseries to protect places for flats of other soft plants or seedlings. In its simplest form it resembles colored window screen. Sometimes the garden or nursery supply shop that sells it can tape edges and install grommets to your specifications. Or it is possible to fasten it. Leave a slight sag. Edges are light weight, durability, and low cost. A special edge, if you need only a roof that is seasonal, is that shade cloth kept and can be readily removed.
Other veranda roofs that are not difficult to remove from rafters and to keep are woven woven and reed bamboo. They form an attractive mottled shade and look more natural than protection material. Like shade material they can be relatively affordable. If bound by wire rather than twine woven reed lasts up to four years and bamboo five years or longer.
Also removable is sailcloth, many folks’s favored veranda roof because of its attractive looks and simple adaptability to many styles. Canvas is among the least long-lasting materials, but is fairly affordable and one of the simplest to replace.
Fiberglass and plastic panels are other cheap materials for roofing a patio, but they aren’t easily removed for seasonal storage. An edge that they share with sailcloth is providing seclusion from overhead windows, notably desirable within an urban garden. Unlike sailcloth, they acknowledge light and heat. The truth is, they trap heat and create a greenhouse effect. By the same token, however, they can be a bad choice for a hot south- or west-facing patio, as they collect an excessive amount of heat and inhibit air circulation.
Wood, in various forms, is the most used covering for outdoor living spaces, mainly because it permits air circulation. It can be comparatively cheap— lath, lattice, and grapestakes; or somewhat to quite expensive —wooden overhead constructions spacing and whose size can change significantly. If you choose wooden overheads (often 2 x 3s or 1 x 2s, laid on edge), remember that not only their spacing but also the direction they truly are put determines how much shade they create. For most shade plants, the lath should be set north south so the bars of sun move across the plants. Sun from lath which is placed eastwest moves slowly and can scorch many plants that are fine.
Instead of making a veranda roof wholly give some thought to planting vines to cover it partially or completely and minimizing the wooden construction. Some vines are fast growing and supply shade within a season.
