I'm installing a concrete tile roof in a dry climate medium wind area. I'm thinking of using TriBuilt Hi-Performance synthetic underlayment. It comes with a 25 year warranty, 10sq roll, and $115. The other two ones I researched were Palisades and Sharkskin Ultra. The Palisades is comprable and the Sharkskin cost $120 more but has a 50 year warranty. Are all polypropelene underlayments basically the same? Or do I get what I pay for?
Fastners are important we just did a ludwieci reset and i used tamkos tile and metal self adhering underlayerment, so we had no fasteners. It went done rather quickly and seals around the tile fastner to boot.Its a lot more money then synthetic but worth it.
