I'm currently in the process of having a home built and met with the builder for the final inspection before closing. During the walkthrough, I noticed several nails on the face of the aluminum fascia. The builder states this is the correct installation method. I don't have any experience, but I found this odd as it relates to why aluminum fascia would be installed. The appearance of the home and waterproofing/keeping the outside elements out of the home's structure. If the nails were instead installed in the bottom of the aluminum fascia, would that not correct both? The appearance would then be clean, with no nails in the front. The nails installed in the bottom would allow gravity to do its part and limit moisture and allow it to escape if it happens to get behind. Attached are pictures related to this question. Any help is greatly appreciated.
