Underlayment

While tile is ultimately the first line of defense against the elements on a roof installation, underlayments play a critical role by providing a secondary level of waterproofing protection directly on top of the wood roof deck. As a crucial barrier that contributes to the performance and longevity of the entire roof system, it is important to choose the right underlayment for your roof and your particular climate.
