My 21 years old house is located in Southern California. I am looking to have the current 1 layer 30-pound underlayment replace prior to installing solar this year.
The contractor is giving me 3 options:
Two layers of 30 Pound Roof Deck Protection
Two layers of G40 Pound Roof Deck Protection or
One layer of High-Performance Titanium PSU 30
Which option do you recommend that I should go with that is best for my roof long term to avoid leaking?
Thank you for your time.
