I’m definitely not looking for a quick reason to not get up there. I’ve been up in my attic which is of this type and it requires extreme caution to squeeze between beams while only stepping on joists - and not getting raked by protruding roofing nails from above. I even had a plumber “get stuck” when he was afraid to go back the way he came.
SOP says: “The inspector is not required to enter the attic or any unfinished spaces that are not readily accessible, or where entry could cause damage or, in the inspector’s opinion, pose a safety hazard.”
