When installing a new roof, it’s important to consider whether the underlayment needs to be replaced. The underlayment acts as a protective barrier against moisture and helps to extend the lifespan of the roof.
While it may add to the overall cost of the project, replacing the underlayment is a worthwhile investment in ensuring the longevity and durability of your new roof. It’s always best to consult with a professional roofer to determine the specific needs of your roof.
