I have what's called a "torch down" or Brie roof. I paid a lot of money for a roofer to fiber glass a small leak in my 14 X 14 foot screened porch. He then coated the roof and it's peeling off in ONE year. I'm not sure what type of coating he used. It is black. I have a feeling this was the wrong coating. This was the best roofer in my area and I am very upset. Before I call him I need to know what you are really supposed to use to coat a torch down roof. And what the heck to do now that what is there is peeling off. I paid $550 and I know - I fell off a turnip truck. But he came immediately, was so very nice and I wanted it done before winter. It was a gorgeous day and rain and winter were coming the next day. I surely expected this coating to last a few years. Any help would be appreciated.
