If you have a house that is about 20 years old and you have noticed that your roof is starting to wear down, then you have two options: you can either have your roof reroofed or you can get an entirely new roof. Depending on several factors, one of these options may be better than another. While your roofer can tell you firsthand which option is going to be best for your roof, it's still good to know some of the distinguishing factors between these two options.
When you have your roof reroofed, it just means that your roofer will apply shingles over your existing shingles. The great thing about this option is that it can save you tons of money because they won't have to wear down your existing roof. Typically, your roofer will just lay a thin layer of shingles over the top of your existing roof which can help bring your roof to life while also repairing any issues. For instance, if you have a small hole in your roof or if you have a few shingles that need to be repaired, then reroofing will be a great option just for repair. At the same time, though, you can use reroofing as an entire roofing solution for the whole thing.
If your shingles are really worn down and peeling or if you have had your roof reroofed before, then your roofer may recommend that you get an entirely brand-new roof. During this process, your roofer will start by tearing off all of the shingles and then inspecting the underlayment. If there is any mold or water damage underneath the shingles, then they may need to tear it off and replace it so that you have a completely brand-new roof.
Once everything has been torn off, your roofer will then either place new underlayment (or not, if it's not damaged), and then they will lay down all of the brand-new shingles. Then depending on where you live, your new roof can last you another twenty years if not longer.
Reroofing is a great option if you want to save money and if your roof is equipped for it, but if not, then getting a new roof is always an option. If you want to learn a little bit more about both of these options, reach out to a roofing professional in your area. Talk with a professional who provides reroofing repair services to learn more.
