I’m getting ready to hand synthetic 1×6 fascia board on my house. This will
be used to mount the gutters as well? Any issues with non-wood fascia behind
gutters? Also, I need to fur the fascia out in order to cover the siding corner boards. I
was going to use 1/2″ sheathing. Doesn’t seem like it should get wet, but thought I’d
ask what folks here normally do. Opinions welcome.
