How To Build A Roof Over Existing Patio Or Deck
If the local regulation of your neighbourhood allows it to be, then you might as well learn how to build a patio roof over your existing deck or patio in order to enhance the look and charm of your house. There are also certain ways you can do in building a roof over an existing slab if the code allows it to be. However, there are also some things that seriously need to be taken into account when it comes to constructing things like this. If you find that your existing slab is not as strong to support the weight of the overhead, then you might have to pour a new footing around the perimeter of the slab or break out sections altogether to create a deeper footing. But then again, if you are planning to build a roof that could cover your existing patio, first you must determine whether or not the local codes and regulation allow it to be situated directly on the slab. If it is indeed allowed to do so, then the next question you have to ask is whether or not it is strong and thick enough to support the weight of the overhead and if it is not, then you have to do create an original foundation for it as explained earlier.
In many areas though, it is allowed to install an overhead above an existing slab if it is thick enough and strong enough. And what is the criterion to determine whether an existing slab is thick or not? The measurement, of course, with 3 ½ inches is the recommended thickness to determine whether a slab is strong enough or not to endure an overhead being built on it. If you want to secure a roof over an existing slab then you have to place each of the post available in their post anchor. Perhaps you can ask the work of professional to do this for you or if you have sufficient knowledge on how to build a patio roof by yourself, you can try to look up some hacks and neat DIY techniques in online or offline references that can help you in great detail.
As for building an overhead over an existing deck, then the first step is pretty much the same as the first one; by checking whether or not the local law and building codes at your neighbourhood area allows the practice or not. If it is, then you can bolt an overhead’s patio posts directly to the pre-existing beams of the patio or decks, its joists, or to the other heavy structural members of the construction. To do this properly of course, you need to have a sufficient knowledge on how to build a patio roof appropriately.
