Hi Mac, We've tried lots of flat tile options. At the moment, I'm a little undecided about what approach is the best. Pro Solar Tile Trac and regular J-hooks such as the ones made by Unirac both work and have pros and cons at Peter mentioned. Some tiles have grooves that allow minimal to no grinding in area where the J-hook protrudes from the bottom of the tile. My main issue with the whole tile setup is that you are still making an unflashed penetration where the lag is actually going through the roofing underlayment. My understanding is that tiles are only the first barrier to water entry and that the underlayment (such as felt paper) is the real water barrier. Quick Mount has attempted to solve this with some of their products:

The real sealing method for the Tile Trac and J-hooks is relying on the base footprint to cover your penetrations and lots of sealant. I suppose as long as you don't have too many missed holes and good sealant you shouldn't have problems. I like Chem Link M-1. Be careful with Sikaflex as it is not compatible with bituminous surfaces such as tar paper (or at least it wasn't the last I checked a couple of years ago). Good luck! -August On Mon, Apr 1, 2013 at 4:32 PM, Mac Lewis <maclew...@gmail.com> wrote: > Hello wrenches, > > I am looking for advice on specifying appropriate mounting for a flat > concrete tile roof.
