It’s easy to forget or neglect the parts of your roofing system that aren’t easily seen by the naked eye. For many homeowners, the roof simply consists of the shingles, the flashing and the gutters. However, it’s important to be aware of the other roofing components as well. Take the roofing underlayment for example. It is an essential part of your roof system as it contributes to the health and stability of the entire roof structure.
