Anyone have experience mounting a tilt up array over a tar and gravel
roof? Weatherproofing, best practices for finding rafters, type of
standoffs etc. The residential roof in question has over 3" of tar (!) so
im thinking 6" stanchion to tilt legs. Any ideas or lessons learned would
be helpful.
Thanks,
