First of all sorry for the ignorance here but I'm no roofer !!
We've got a damp patch with all the rain just above our bedroom window and at first I though the cavity wall guys had forgot to fill in one of their bore holes.
When I've got up the ladders I've noticed one of the first slates has slipped into the gutter hence water has been getting underneath the slate directly behind and then running into the cavity.
I've placed the slate back but my question is how do I secure it ?
The slate has two holes in it which I assume were nails/tacks but how does the nail go through without cracking the slate underneath ?
Many Thanks
