If you’ve been exploring roof replacement options, you may have come across the term “reroofing” or the practice of installing a new roof over the old one. While it’s available, you really shouldn’t choose this option. Here’s why.
Not all homeowners are familiar with all the components that make up residential roofing systems. Sure, they probably know what shingles are and can maybe even point out their roof’s flashing, but what about the stuff that’s underneath? One of the most important structural components of your roof is the decking. If it gets damaged, then it is definitely not something that you want to ignore.
