vinyl siding trim /soffit questions

I will be vinyl siding a two car garage ( detached from house) shortly and would like some opinions on how to best trim the soffit and doors. It basically has one window, the man door and the garage door. Someone gave me a 30' coil of 24" wide white coil stock for starters. Anyways,

Soffit - The eave is 6" and the face ( where gutter attaches) is 6". My thoughts were to just brake up 90 angles 6x6 and attach to face of soffitt and hold up back edge with nails and the top J-channel of the wall. Is there better ways to do that small of a soffit.

Doors/windows - If I brake up the aluminum into angles can these be put in place later after the siding is complete on a wall. On my neighbors house it looks like they just bent up U shaped pieces which slide behind the J-channel and then nail to the face of the jambs. Is there a better way to do this.

Thanks for the help

It all depends how nice of a job you want to do. Personally, I think that bending the soffit and fascia in one piece is something that should only be done on a shed that is in the backyard that no one will see. I'd put aluminum soffit on the soffit. Doing a simple 90 degree bend 6x6 is a bad idea because it will be very wavy. Coil doesn't lay flat unless it has multiple bends, kinks or hems in it.

30' of coil will make you 100' of 6" fascia cover (if 1" bend on bottom, 5" tall) and should leave you a 12" wide, 10' long pc to cover your door and window if you don't screw anything up. But you'll definitely need more coil to cover the garage doors.

Have you ever run a metal break before? You don't usually want any nails exposed in your cladding if you can help it. Best thing to do is bend a nailing fin into your window/door cladding so that you can nail the trim to the sheathing. It also acts as a flashing around the windows and doors. Otherwise, nail to the side of the brickmould, where nails will be covered by the j-channel. If you have a storm window, the coil is often bent behind the storm window, and the storm window screws pierce it. Doors are wrapped in a similar manner, brickmold first, in once piece, then wrap the jamb second. The fascia cover that you buy has ribs in it to keep it straight, and a hem in the bottom lip. One idea would be for you to buy premade fascia cover, and use your coil for the garage doors and other trim. You can also buy or make finish trims, which your fascia can "clip" into, if you have a hand tab punch.

Bending and installing aluminum cladding isn't usually something I'd recommend for a novice, unless you have someone you can get some pointers from. If you have add'l questions just ask.
