I dont think teslas standard racking system works on them, and tesla will not use anything other than their standard racking system. I dont understand the question "has anyone dealt with this issue?" though. What do you mean by that?
If you mean "Can I force tesla to install on this roof?" the answer is "no". If you mean "Can I get solar on this roof?" the answer is "yes, from someone other than tesla who is willing to to use rack / installation techniques that will work with those fragile tiles.
