Installing Soffit and Fascia (Avoiding Damage)

What happens here

Install the soffit panels to the underside of the roof's overhang, using a staple gun to secure them. Next, attach the fascia boards to the edges of the rafters. The builder warns against face-nailing or over-driving nails into the fascia, demonstrating how this can create unsightly dents and an 'oil-can' effect, detracting from the finished appearance.

Goal: Install soffit and fascia for a finished look without cosmetic damage.
