I get those questions about the roof from lenders quite often. My comeback answer is Hellifino.

The strangest one came when a lender ask if I could determine if the house was on a landfill or not.

I told them I did not do any excavating of the soil so so I guess it could be a possibility. Told them to contact the city or the county on that one as I do not carry a backhoe in the toolbag.
