imported_John SmithDo you think it would be better to go ahead and install a wood screw into the hole and then siliconeroofing sealant/ over it?

Seems like a belt and suspenders approach, but I think it would be better than just trying to seal over it.

No. Lift shingle tap, slide in a piece of galv. tin over the hole, apply sealant on top of tin, press tab into sealant.
