I have a field stone cottage. The soffit that is currently there is wood and I want to replace it with aluminum.
My problem is on the inside of the old soffit it goes right up against the field stones. What would you suggest as a method to attached the inside j strip, I was thinking of a narrow wooden strip attached to the existing soffit and then attach the j strip to it. Is there anything else that I might consider or am I missing something.

Thanks in advance.
