Installation of vinyl patio covers is comparatively easier, as against wood or metal. Covers can be either one piece of sheet or if it’s more, it can be installed by overlapping the pieces in 3/4 inches to 1 inch, by welding them together. As against common belief, there will not be any leakage of water if done properly. The cover will be stronger, though is consists of two separate pieces. In fact, the blended area will be twice as think, offering more protection from heat and rain.
