Steps
Measure the fascia/soffit run and transfer layout lines onto the aluminum coil stock
Load the coil into a siding brake, aligning the marks with the brake's jaws before clamping
Bend the metal to the required angle, scoring and re-clamping as needed for tight hems or multiple bends
Fabricate matching pieces for corners, drip edges, and transitions using the same brake
Fasten the formed trim so it sheds water away from the wall and ties into the WRB/flashing behind the new siding
Known gotchas
Field-bent trim that doesn't match the original profile closely can create visible seams or water traps at transitions — mock up a piece before running the whole job
Coil stock thickness/gauge affects how it bends; using a brake sized for a different gauge can crease or crack the material
