Hello,
I am having a roof re-slated.
It is an old house; field stone wall with rubble infill, sarking board below slates.
The roofer has dobbed mortar along the bottom of the roof on top of the roofing felt, he has then pressed the bottom course of slates into the mortar.
This seems daft to me, I thought that the felt was meant to be able to drain in the event that water gets under the slates?
By building a wall of mortar at the bottom of the felt he has prevented the felt from being able to drain.
Any thoughts?
Thanks
