DPW Easy Feet are cost effective and work well, but plan well cut the stickem layer gives you only one chance. Turn an L foot upside down, fasten it to the easy foot and use a mini on the L.

Re: [RE-wrenches] Conduit supports on sloped composite shingle roofs
I'm surprised this hasn't really come up for us. I can't remember the last time we ran conduit along a pitched roof other than very short runs to an eave where we penetrate the roof and soffit to run down an exterior wall. I'm guessing you are dealing with an inaccessible attic. We just about always get into the attic right from the j-box location. I think I'd use the QuickMount solution if we had to do this.

I always use the quickmount conduit flashing. It doesn't give a lot of room between the roof and raceway however. Maybe the foam block supports typically used for raceways on flat rubber roofs?

Re: [RE-wrenches] Conduit supports on sloped composite shingle roofs
How high are you wanting to get the conduit (EMT?) off the roof? I have been using Kinetic flashings and rails for mounting PV these days. Great stuff. There is a base that mounts directly onto the shingle and then a flashing goes over it. The base that goes under the flashing has two holes for lags bolts or in your case a couple bolts you can attach to be roof sheeting and then it has a stud for mounting the L-foot (or whatever you want to attach to the stud. You could use a standard 3 L-foot and either use the provided oblong hole or drill your own. If you want to get more height then they also have 4 and 5 L-feet. http://kineticsolar.com/ benn benn On Sep 22, 2014, at 3:43 PM, Chris Mason cometenergysyst...@gmail.com wrote: I'm curious what methods people are using to mount, flash and stand-off conduit from the comp. shingle roofs.
