Wrenches, I don't see a lot of tile roof in this area but I'm working on a project (new construction) and the roofing will be metal roof tile, see here.metrotile_roman.cfm <http://metroroofproducts.com/metrotile_roman.cfm> . Recommendations I've received for attaching the racking include a tile hook or hanger bolts.
I have used them but always had a hesitation with hanger bolts since the whole array is being supported by a few inches of free-standing bolts, and with no 'cross-support' (triangle) I don't see what is stopping the array from keeling over and bending/snapping the bolts, especially under a heavy snow load! I would love to hear some comments on this concern. Hanger bolts or tile hooks.What does the collective wisdom of this list have to suggest/recommend?
