Sometimes I come across a situation where the sellers have either painted the attic (white most of the time) or try to keep me from inspecting the attic area.
The is a instant red flag and once I gain access, typical I find a lot of damage.
Just a few instances of severe attic damage from a previous fire and one attempt at hiding the damage by painting the attic. Always make sure the attic is inspected when buying a home, it could potentially cost you thousands of dollars!
