Yep - best talk to the surveyor as PoP says. I just wondered if the rotted
chimney trimmer and the stain in the bedroom could both be due to the leaking
flashing? As it's a 60's house the lead might have perished, but my guess is
it's more likely that the flashing has slipped out of the joint and just needs
re-wedging and pointing.

"Within the limits of the inspection" simply means in accordance with the
standard limitation clauses somewhere else in the report, which all surveyors
have to include on the instructions of their insurers. It goes along the lines
"we have not inspected hidden or inaccessible parts and cannot confirm these are
free from defects".
