It's the style with the metal framing (3' or larger spans) and just insulation and the roofing material between. What do you guys do when you have to setup a tripod on such a roof? Two legs could probably be secured to the metal framing, but what to do with the 3rd leg is what puzzles me. I have installed on this type of roof before, but it was with a DSS mount. I just sucked the 2 bolts holding the DSS down tight and used nuts and lock washers on the back side. I may have left the remaining holes unsecured. I seriously doubt I could do the same thing with a tripod. Bolt Unistrut to each "foot" of the tripod, rotate the tripod so that the Unistrut is perpendicular to the metal roof, and screen in to the ridges with sheet metal screws.
