In most homes, metal roofing can be installed over asphalt shingles. However, if you are going to install metal roofing over a slate roof, for example, you will need to make sure that there is not too much overlap in the metal roofing. overlapped shingles are damaged by water leaking onto the metal surface, and it will be necessary to get them replaced. In the worst case scenario, the water may even get underneath the metal roofing, causing it to rust. When it comes to metal roofing, getting the maximum life out of it is essential.
How much overlap on metal roofing depends upon many factors. For instance, the shape of your roof is a determining factor. If your roof is oblong or if you have steeply pitched roofs, you will need to pay closer attention to how much overlap there is. On the other hand, flat roofs have less of an issue with overlapping as compared to the other types of roofs.
Another way of looking at how much overlap on metal roofing is based upon how much money you are willing to spend to get the job done. Certain types of metal roofing are very pricey, and this is something that you will need to keep in mind before installing the material. Also, you need to take into account the cost of removing the old roof and putting up the new one. Metal is a material that is quite expensive to install, so if you are planning on doing this yourself, you may want to choose another type of roofing system.
Before installing metal roofing, you should also take into account the possibility of having to replace your existing roof at some point in the future. This is because metal is extremely durable, but it is not indestructible in the long run. It can, however, be repaired after damage has been done, but you will need to hire a contractor for this task. If you plan on installing your roof yourself, make sure that you know how to properly do so and that you have all of the necessary tools to complete the job properly.
The third way of examining how much overlap on metal roofing occurs is based upon how easily you can move the panels around. Overlapping panels will typically be fairly heavy, so if you are trying to install these panels on your own, you will need to make sure that you have a lot of strength in your arms and legs. This will help ensure that you do not have any problem trying to install these panels. In fact, it may be necessary for you to have a permit in order to install these types of roofing systems, so make sure to check with the local building codes. This is especially true of larger panels that exceed about 15 feet in length. If you cannot get your panels to overlap with each other without harming the roof, then you may have to hire a professional in order to move the panels to an area that will allow them to remain parallel.
These are just a couple of different ways of examining how much overlap on metal roofing occurs when you are installing new panels on your roof. These overlapping structures can occur, even though you may never have to worry about them, so it is always a good idea to examine your metal roofing thoroughly even if you never have to think about touching or stacking overlaps. Metal roofs are one of the most durable types of roofing materials available, but they do have their weaknesses, which means that it is important to understand these as well in order to ensure that you are installing the best metal roofing system possible.
