I'd suggest using some of that 20-yr composite caulk. Silicone will work too but not last as long; that black rubberized roofing cement stuff is EVIL to work with, plus which it gets crumbly and leaky after a coupla years.
You wanna make it look nice from the outside, apply a blob of caulk from the INSIDE, making sure it squooges out the hole, then go up on your ladder and press it down and spread it out, just a little bit. Leave it a little 'proud' of the surface.
Good luck, have fun,
Pat
