I want to attach a block of pressure treated wood to my slate roof. I want to secure it with 4 bolts. This way I can attach my satellite dish to the block of wood.
I just bought a english tudor house which has a brand new Virginia slate roof on it.
How do I safely drill holes for the bolts through slate without damaging or cracking it?
Do not drill holes in a new beautiful slate roof.
Do not mount a satellite dish nor a block of wood to a slate roof.
Not only unsightly, but a leak and a crack are 100% probabilities.
Go figure a better way. Mount the satellite dish somewhere else.
A southern facing wall is recommended for mounting the dish. http://www.msnusers.com/clift corn stoves, fireplace inserts
