What happens here

For the soffit installation, first install an F-channel along the underside of the fascia board. Mark and cut the F-channel to fit. Next, install the vinyl soffit panels. Ensure each panel is fully tucked into the F-channel. Staple the soffit panels only in the pre-defined grooves, not in the center, to allow for expansion and contraction without bowing. Install any cap posts or bird boxes at the ends of your overhangs for a finished look. Finally, install the aluminum fascia over the exposed fascia board. Start with a plumb cut at the top and fold the aluminum fascia around the beam. Be cautious not to face-nail or over-drive nails into the aluminum fascia, as this can create dents and an 'oil can' effect, detracting from the appearance.

Goal: Finish the underside and front edges of the roof for aesthetics and protection.

What they say

Hide

it down, and use this to cut your edge. Now we'll staple up our soffit. The soffit just gets tucked up in your F channel, and be sure you're using galvanized staples, and staple it in the grooves. If you staple in the center, it'll bow this in and make it look bad. You want to be sure this groove is fully in because if it's not, this will hang down and that this edge is not past your fascia. Now we'll install a cap post and a bird box. This can be done in a few pieces. You just want to be sure that you have places to fasten this on the bottom edges. We'll install this fascia after the soffit. We'll start by getting a plumb cut at the top so it fits at the top. Now we'll mark our beam and fold it in. Mark and cut our fascia. Now we'll install this front fascia. If we face nail an overdrive nail, this can dent and oil can your fascia. We'll install a J channel on the inside
