Chris, You might consider the DPW EasyFeet. They mount to comp shingles with five course thread torques screws. Kind of a wide L foot. http://dpwsolar.com/images/PDFs/ApplicationInformation/Easy_Feet_Installation_Guidelines_Version_1_Rev_E.pdf 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.
