Default Spray Foam & Soffit vents

Inspecting in south Alabama a home with spray foam insulation. Soffits were completely sealed appears to be creating moisture issues. Should Soffits be vented?
Thank you

Sealed and/or conditioned attics are a type of construction that can't be described adequately in a few short bulletin board posts.

I recommend you do some significant research.

Roy's post provides an excellent background paper by a well recognized and professional forensic practitioners. Again other "house as a system" considerations needs to be part of the overall best way of responding to this inquiry.
