I would like to install a solor motion sensor light on the top of a eave, on a lower portion of my roof. The only way to do it is to screw it on top of the shingle. Is this okay? Any risk of damage?
I see people have installed satellite dishes on top of shingles so it must be okay, right?
Sorry if its a silly question. I'm generally not too handy.

yes it's fine. There's some roofing caulk you can put into the screw holes before you put the screw into them for extra sealing.
This is they way I would do it. Waterproof washers might also help, though I am sure these some materials (especially rubber) would deteriorate quickly on a roof, due to the heat and exposure to direct sunlight.
If caulk is not used, what risk is there (if any) of water leaking into the attic (through the holes and around the screws?)

The risk is water leaking into the attic. It will deteriorate the sheathing under the shingles. It can also keep leaking and get into the house ceiling, or into the walls.
It's never a good idea to let water get in where its not supposed to be.

I figured as much. I am a little handy, but I have never put holes in my roof. I therefore did not want to speak as if I had experience in this matter.
