IMHO the TileTrack system for flat concrete tile or S-tile is the best approach there is. The 3/8" SS all thread can be accommodated by a ~3/8" hole in the tile, leaving an exceedingly narrow gap around the all-thread to caulk. By way of distinction, I never use tile track on comp-shingle or torchdown roofs, using instead Fast-Jacks and Oatey elastomeric flashing. - Peter

I think that some flashed footings are better than the Unirac L feet or Prosolar's TileTrac foot, but the flashed footings cost a lot more $, and some flashed footing products seem flawed (less watertight) They are asking me to uninstall two commissioned systems from last week, and replace the footings with flashed Fast Jacks, even though the documents detailed the penetration method. I am looking for some good info that supports flexible installation methods, including caulked footings. Our industry has come a long way from the early days of racking on slotted angle iron with steel L-brackets for feet, but those experiences tend to give me confidence in continuing to use caulked footings.
