About to drill through the roof to mount solar panels- tips?

Yah.. don't drill through the roof!

I guess that's why I posted here first- I'd have to fill the holes with a sealant like I see around the other stuff up top... but isn't drilling 'through' the roof kinda the only option here? That's what I was planning on.

Or maybe that's not necessary simply because the screws don't go that far... err, wait ok I get it now. Drill shallow. They're simple L brackets. Renogy kit. But what about the wiring? I guess that's what I'm thinking of about having to drill 'through'. Thanks.
