For some reason, the surface of my roof is hanging past the fascia by 3.5" and I can't figure out why or how to fix it. I guess it's actually that the fascia and subfascia are stopping short of the end of the roof by 3.5" as it seems as though the roof surface is hanging past the baseline the correct amount. What setting do I need to fix to get the fascia to build in the proper spot so there isn't so much roof surface overhang?
