You put a lot of thought into what finish goes on top of your roof, but your roof is so much more than that. Majority of the quality tile / shingle manufacturers offer 30 plus year warranties, but since the underlayment is the only moisture barrier used in the assembly, the system integrity will be compromised by employing an inferior quality felt or synthetic roofing underlayment. The traditional felt having a more limited life becomes a weak link in the tile /shingle system.
For minimal cost you can upgrade your roofing system with a rubberized asphalt underlayment “Layfast SBS”.
