If you want to have as little effort as possible with the patio roof, then you should rely on materials such as steel or aluminum. While wood offers a natural look, it also needs regular maintenance. Glass or roof tiles mean that the cover has a permanent value, while plastic or bitumen are relatively cheap to buy but may have to be replaced more often so select wisely the so called screened in porch in Spokane Valley, WA for your home.
Wood as a natural material is usually very cheap, although you should pay attention to the differences in the quality of the wood. Spruce, fir or pressure-treated wood are ideal. Aluminum as a light metal is also available very cheaply. Due to the low maintenance effort, it not only offers a price advantage.
Steel is always a tailor-made construction, which of course has its price. The next step is about the materials that are needed for the cover. Although few are cheap, it cannot compete with other materials in terms of design. Transparent plastics are certainly not cheap, but they are significantly cheaper than glass. With plastic you have the choice between the corrugated shape and the web plate. Glass is definitely the most expensive option, but also the finest. Only special safety glasses are used here, which are protected against glass breakage. Roof tiles offer a special visual appeal, but are not exactly cheap. The only advantage is that you can choose them to match the roof of the house.
In order to determine the correct post thickness for the patio roof, you first have to calculate the statics. There are both mathematical and graphical options for this. So before you start building a patio canopy, it should be clear that such a canopy has to withstand a lot. It not only has to withstand the wind, but also any form of precipitation, the different temperatures and of course the humidity. Furthermore, the terrace roofing must not endanger people under it in any situation.
Therefore, the following requirements arise for the construction and ultimately also for the post thickness.
