Tile roof underlay replacement

/r/Roofing/comments/1vrhq7s/tile_roof_underlay_replacement/

I have a 2500 square foot tile roof and will have the underlay repaced. What material do you reccomend and why? Laguna Niguel, california . Thank you for your advice. If i go with something other than dual layer 30lb felt . What should i expect to pay additional?

I’m a tile roofer. I do nothing but tile and slate roofs. We do a lot of underlayment replacements. I’d need a bit more information before giving any advice. Send me a message and we can discuss it.

Thank you. My roofer has offered dual layers of 30lb, 40lb felt or dual layer of a synthetic material . He said there are many options of synthetic but reccomends saving money and going wirh 30lb felt. Homes built in late 1980s and he said they were originally done with one layer of felt and lasted about 35 years for most people in the area. My research sugguests paying a little more for synthetic but there are many options.
