How to fasten it on a sloping roof (slated roof or cement asbestos roof)
The fastening on a slated or cement asbestos roof is comparable with the fastening on a tiled r oof.
But you have to screw-in the ring-screw through the roofing into the foundation. If you have a wooden
foundation screw it into the boar ding or battens. If you bore slate or cement asbestos you have to do
it without the slugging device to get around splitting the plates .
After screw-in the screw you have to seal it up with silicone or another sealing compound lik e this.
