Best Method For Cutting Hole

Hello,
I am installing a new 6" kitchen exhaust duct and boot. The roof has plywood sheathing and one layer of asphalt shingles.
What is the best method or tool to make this cut? I plan on marking the center of the hole on the sheathing, in the middle of the rafter bay and drilling a pilot hole to the exterior.
Is there a smarter way to position the cut, so the boot will fit easily and make the install faster and easier?
Thanks,
Lou

Hole

Your method of locating the hole is good.
Go up on the roof and mark the circumference of the hole. Cut the shingles and felt with a utility knife. Then cut the sheathing with a jig saw. Or, if you do not mind sacrificing a blade, cut shingles, felt, and sheathing all at once with the jig saw. Good luck with your project.
