Following is background and question
Background: We agreed and paid for “Titebond” as moisture barrier. We questioned installer for the color of the product and found out that installer applied “Roofer Choice 66” instead. Looks like “Roofer choice 66” is cheaper. After grilled further, he agreed to put “Titebond”
Question: Is it ok to apply “TiteBond” over “Roofer choice 66”? or we have to do any further clean up. I do not trust my installer anymore.

Any answer is appreciated. Thanks for your time.
