Bat on a non-slip roof: National Trust adapts manor for nocturnal residents

Oxburgh Hall in Norfolk gives tiles a special coating to stop bats slipping off as part of 6m roofing project

Bats have probably been in the attics of Oxburgh Hall for centuries. But how can they return for a good day's sleep when the National Trust puts new and unfamiliar tiles on the roof?

The trust on Thursday revealed the lengths to which it has gone to keep the bat residents of a historic manor house in Norfolk happy during a 6m reroofing project - including specially adapted tiles which they can happily scoot up.
