Hi… needed some advice and I’m sure this forum has the answer!
Just had a surveyor who has noted that in the older part of our house which dates to 1905, there is no felt under the slate roof.
As far as I’m aware, this is quite normal for this period of house, and since the house has been in the family since it was built, we have no recorded evidence that it EVER leaked….
Should we now consider felting it or use some other spray on membrane or just leave as is?
Thanks 🙂
