I have installed my antenna a comet gp3 about 25ft high on my roof using 1 1/4 pipe, I have ran a bare copper no6 ground wire from the mast through pvc pipe about 40ft to a copper ground rod 8ft long drove in the ground, my question is, is this a good enough grounding method?

that is a good electrical ground , but if possible run a second ground strap to a second ground rod for a station ground for RF, and make it as close as possible. it will also help.

In addition to the above advice make sure all your grounds are bonded togeather. The 8 foot ground rods should be about 16 feet apart for maximum ground conductivity. Also make sure your AC panel has surge protection for 95% of home lightning damage is via the AC feed from the pole mains.

You've grounded the antenna mast but you'll also have to provide lightning protection to the coax leading into the shack.  Check out Polyphaser or ICE devices for this.  Tie the grounds from these devices into the same ground rod as well as the shack ground and the AC ground.  Do a search on the archives here on eHam on Grounding and you'll get tons of info.  Phil  KB9CRY
