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

[Carl Adams]

Chris,
You might consider the DPW EasyFeet. They mount to comp shingles with five course thread torques screws. Kind of a wide L foot.

 You can come off of that with a piece of DPW P6 aluminum channel or square aluminum rail and then mount stainless steel mini for conduit supported at any height you wish.  Lead time on the easy feat is sometimes long. 

With Regards

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.

We don't do a lot of shingle, mostly metal and concrete, so we are less that familiar with the options. We used SnapNRack flashed mounts for the rail system, but they need a rafter under them and the conduit run will not be above rafters.
