Removing/Replacing Aluminum Fascia Trim
 

Description: Five year old vinyl sided house with J-channel abutting
'white aluminum fascia
'trimmed' areas which surround the sides and tops of both garage doors.
This aluminum
trim is likely covering 2X4 rough studs, and appears to be taking water
underneath (despite
having been caulked between J-channel and alum. trim) as I've removed
fungi from between the J-channel and the trim on a couple of occasions
and re-caulked. Aluminum trim also appears to be separating and working
its way out from under J-channel at top of doors. In fact, I've seen
neighboring houses that have done exactly that. I'd like to remove the
alum trim before it becomes a bigger rot problem, but I'm thinking
composite material is not a good solution as the alum. covered
underlying wood is thicker than the J-channel edge (protrudes out by ~
1/2" or more) and covering all sides/edges watertight-- especially
adjacent
to the J-channel edge -- looks impossible. Any recommendations? TIA!!
