I'm not sure I have the whole picture yet. (you can post photos)

What style roof are you working with? Hip, Gable or other? How much overhang do you have?

Is the antenna on the roof? On the east end? How is it mounted? Tripod, chimney kit, guyed mast...? How far from the nearest roof edge?

Are you referring to roof shingles or siding?

Are you disconnecting cable TV service and re-using left in cable? Is there already an established ground connection?


Generally:

Grounding the coax near the electrical service is usually the best option. That's were the ground rods are going to be located typically.

I try to route the coax over the edge of the roof at the point closest to the mast / tripod. I don't like the thought of a cable running level across the roof in a way it could catch debris and then form a dam to pool water. Once I'm over the edge, stapling to the siding or soffit where the two meet will usually provide a route all the way around the building if needed. Another common option is to drop down to the level where siding and foundation meet, but doorways and their porches can be tough to negotiate.
