I've done a lot of installs drilling into the roof above an interior light. It's very safe especially with today's silicone's. I have never seen one leak. But, notice the picture of his roof with the dam removed? see the dust? That area stays dry even in a downpour! So even with no silicone it would hardly leak. Plus, with the roof rack you have a gazillion holes up there anyways.

If you got balls to drill. (You should grow them reading this) after you drill hole, take something larger and kinda push up from inside to make a pimple, water will run away from hole this way, then put silicone on hole and install grommet, wire and silicone again. Hurricane proof!

The absolute best silicone is Above/below the waterline marine grade silicone in boat dept of wal mart. $5 But any will do. MC

Isn't all that dirt there because the air dam actually traps it there?
It's been my observation that when washing the truck, all the roof water runs under the basket, to that specific area, and then is usually the last part of the truck to drain dry.

Before my install I pulled out of a downpour and it was dry up there. I'll watch next time I wash it. But it won't leak I can assure you that. MC
