My soffit has a 2 inch wide vent and there is a portion of it that was
damaged (about 6 inches in length). I can cut a piece to replace it,
but I cannot figure out how to attach it from the inside. There is no
way to reach it from the attic, it's at the end of it and it's way too
tight. So I have to try to do it from below, seems I have to glue it
since there is no way to nail or screw it but even using glue is not
going to work if I cannot apply any pressure on the other side.

I hope I don't have to open a hole in the T&G T-111 wood soffit just
to attach the vent. There must be a better way?

Thanks,

MC
