Metal roofs have both durability and longevity, but they are often being used in commercial setups. In humid climate regions, the metal roofs are way better than many other roofs as they do not absorb moisture or transfer it to the walls causing trouble for the homeowners.
Unfortunately, many people shy away from investing in a metal roof due to higher costs. It also has a little high cost when it comes to installing them, but the long life of these metal roofs pays off well. This leads many to ask whether a metal roof can simply be installed over top of a shingle roof. We’re here with your answer!
Can Metal Roofing Be Installed Over Shingles?
Let’s suppose you have a shingle roof and now you are thinking of getting a metal roof after hearing its benefits. Would you have to tear off the shingle roof? Well, that is not the case here, metal roofing can be installed over the shingles.
Metal roofs are lightweight, and therefore they can be installed over the shingles. However, some considerations can be kept in mind, for example, the building codes. You must check the building code of your locality so that you could easily install the metal roofs over your shingles without any notice. This will also help you to stay safe after reading the area codes.
Ensure Your Shingle Roof Is in Good Shape
Firstly, you must ensure that the shingles are in good shape before you install a metal roof over them. Usually, over time, some shingles broke off from the roof or there are cavities in the roof, you must fill them first. Once it is done, you can move on to the next part.
This will not only make your life easy, but the metal roof will get a place to hold itself with the help of screws. The shingles are a better option than plywood to hold the metal sheets.
Keep Building Codes in Mind
Some codes need to be followed in the state regarding the building codes such as you cannot have two layers of roofing materials in the residential area. The reason is that when most house trusses were engineered, they were designed to only hold so much looking weight.
There is a chance that the truss could fall that is why you cannot add too many layers on the roof. This is the reason why some counties would want you to remove the extra layers from your roof, especially in the areas where there are hurricanes. Only in this way can the building department ensure that the plywood is in good condition and capable of holding another roof.
Installing Metal Roofing Over Shingles
When metal roofing is installed over shingles, two main methods are used. The first method is using the existing shingles and a new underlayment over it to cover the old roof and then adding the metal roof over it. In this way, you will get an extra cover buffer zone between the metal and shingle roofs.
The second method is straightforward, in which you install a metal roof with a shingle roof with the purlins. The purlins are screwed down to the roof deck, and the panels are attached. This method gives the installer a nice flat surface to install the metal roofing panels down to without the many grooves and irregularities of the shingles.
