I questioned the roofer about it and he was quite defensive. He claims they are the same product, just made by different companies, that he tried to order the GAF at the last minute but they were out of stock and they provided this as a equivalent alternative.
Its seems to be made by a reputable company with similar spec sheet. Other than being piqued that the roofer didn’t disclose this upfront should I be concerned? Does this product provide similar performance and breathability?
I am being charged a $330 upgrade fee over 15# Felt for a townhouse which would use less than 10 squares (1 roll). Does this price make sense, and are the Gaf and Berger products comparable in price?
