Mount options for Silicon coated roof

[Shimmy]

Other than a traditional rail system, are there any good mounting systems that work well with a roof that has had a silicon coating applied? Whatever I go with I will likely have the roofing contractor come back and add a layer over any new penetrations. The underlying roof is modified bitumen and it is a cathedral ceiling below with no attic. Rafters are TJI's on 16" centers and decking is likely just 1/2" plywood.

The panels will be installed parallel to the roof plane and can easily be landscape or portrait, although portrait is a little easier to access. Only for 6-8 panels. No snow risk.

Thanks!

Solar panels like around min. 6 inches of distance from the physical roof material.
Mostly due to COOLING under and over the panels.
Failure to mount them thus will hasten the end of life for your panels due to prolonged higher heat.
A cooler panel will also produce more amps/watts than a serious hot one.

The same reason not to let the cables lay directly on the roof but rather be hanging from J-clips attached to the railsystem and kept as much as possible in shaded conditions.
