Hi, I am not sure where to put this questions. I wish there was a roofing forum! Anyways, I know some of you old house people have gotten metal roofing so I thought you could help me.
we have an c1850 farmhouse and are thinking about standing seam roofing. The owner of a metal roofing company said that he doesn't think we need a tear off. We have ceder shakes, maybe some metal roofing, and at least one layer of asphalt roofing. I think we have two layers of asphalt but can't prove it.
I thought there was a law in NY state saying that you can not have more than 2 layers of roofing. The owner of the company said there was not.
He thinks, because of the age of our house and the roof decks on old houses, that the metal roofing wouldn't add much weight and it would not be a problem.
We would LOVE to avoid a tear off if we can, however we want to do what is BEST also.
We do not see any bowing in our roof. What other sort of things would show that there is too much weight on the roof?
The roofing also ranged from 400 - 700 dollars a square, if anyone is curious.
