Don't do that. Flashing is usually for wet areas, and dissimilar
metals (like steel staples against aluminum) are not going to
last. Rather, pierce the flashing with a punch and use aluminum
nails. Galvanized (zinc surface) is maybe OK if you keep it dry,
like with a dab of tar/caulk/sealant.
Agree with Doug (below). I stapled my soffits on with a narrow crown staple
nailer but the staples are galvanized, greased somewhat and should never see
rain.
The T50 staple system staples would definitely rust within days and are not
capable of holding anything exposed to any wind but....
Has anybody ever seen a 3/8" T-50 staple that was completely sunk flush by
any machine, yet?
I doubt the staples are capable of being driven into, even soft woods, that
deep without being crushed.
The aluminum installation compaines use steel screws painted white and made
especially for aluminum installation. Use alum nails (painted) for smooth
surfaces that look bad with machine bullet screw heads in rows.
I have been instructed not to use aluminum directly on PT pine lumber,
either, due to electro-galvanic reactions eating it away.
