[RE-wrenches] Conduit supports on sloped composite shingle roofs

[Chris Mason]

In a hurricane region, we can't use glued supports.
Caddy supports are for flat roofs. These are 30 degree roofs.
I think I am going to use unistrut with two holes bored in it, washered
screws and sealant, and a HDG conduit clamp.
