How to correctly install aluminum fascia? With vinyl soffit I am more
or less clear: install J-channel, put the soffit one side inside the
channel, nail another to underside of wood fascia board. But with
aluminum fascia I am unclear how it is installed. I am going to use
pre-bent 6" wide 12' long aluminum fascia available at HD or Lowes. It
is already pre-bent L-shape and matches my 6" wood fascia board. I
understand that I wrap it wound the board and nail it with galvanized
roofing nails underneath the board covering the soffit. Where does the
top of the aluminum fascia go? Do I put it between plywood roofing
sheathing and roofing shingles? Does it go on top of whaterseal
membrane? Do I need to attach its top or face with any fasteners? What
about drip edge? Do I need one? Which one to use and how and where to
attach it? I will have gutters installed over fascia face.
The link to fascia/drip edge drawing would be very helpful.
One uses a hand brake to wrap the non-primary view around any corners
leaving the primary a clear line of sight.
You nail it with painted SS trim nails using a nailset so it does not look
like an elephant walked on your trim
It tucks under the drip edge. No drip edge a reverse bend is used to press
against the shingle overhang. No drip edge? I have seen trim strip used
along the top of the run, then the fascia tucks into that and any gutter
mounts below it.
Others will disagree, some face nailing with the trims nails, mostly at the
overlaps is necessary if you want it to be wind resistant. This is not so
important when gutters will cover the board.

Next time get a licensed roofer that can follow the building code. For
now, try to fix it by tucking an L-section flashing secured under the
shingles with roofing cement. Installing gutters will hold it in
Not sure what you mean by "wrap it around". The fascia is installed with
the bent leg underneath, so it covers the ends of the soffit panels.
Just slide the fascia up into place and nail through the face with trim
nails, not roofing nails. The ends can be bent to tuck neatly into
The top edge would normally slide behind the face of the drip edge.
Thank you. As I mentioned before I do not have drip edge. Roofing
shingles just overhang plywood sheathing. I am trying to figure out if
I should install drip edge first and then slide the fascia under the
drip edge. My understanding now that aluminum drip edge is usually
nailed to the roofing plywood sheathing before shingles are installed.
I obviously cannot do this now after shingles are in place. I wonder
how to attach the drip edge without nailing it or if I can skip drip
edge and just slide the aluminum fascia underneath the roofing
I also read that it is better not to face nail the fascia and only
nail it from beneath to fascia board and face will eventually be
attached to the board when gutters are installed.
That's a new one on me. I don't think you could nail the underside of
the fascia. There is nothing solid to back it up, it's just resting on
the soffit panels, which aren't solid. You would just bend the heck out
of the fascia. Just face nail it enough to hold it in place until the
gutters get installed.
Not a fan of metal-wrapping fascia boards, aka gutter boards, at least
not if the wrap doesn't go all the way up under the drip edge of the
roof. The wrap on this place keeps the fascia board wet all the time
(due to gutters filling with water whenever the too-small downspouts
clog), and several sections have rotted out. One spot even directed
water across the soffit, where it got into the wall and rotted out the
window over kitchen sink, which previous owner replaced without solving
the water problem. Fix ain't gonna be cheap or low-labor, so in the
meantime I drilled some weep holes in the wrap to let water out. The
casual observer can't see that it is trashed.
If I thought this place was worth the money, and I had the siding
replaced, I'd have same crew strip the soffits and gutter board, put up
plastic fascia, and plastic soffit. Need more attic venting anyway.
Outside trim is one area where that plastic wood stuff made from old pop
bottles really excels.
I thought from your original post that you were nailing the outer ends
of the soffit panels to the lower edge of the 2x6. In that case,
the aluminum fascia lower bend rests on the soffit panels, which are not
If you are using F channels on the house and on the back side of the
2x6, then yes, the aluminum fits against the edge of the 2x6 and could
But even then, the 2x6 would have to be really straight or the aluminum
might buckle. Face nailing avoids buckling.
