Never had a damage claim, but other installers have.... usually it's roof damage (I'd never put an FTA on the roof personally anyway, yes it's possible, but those dishes are just big) or holes in siding, drywall, etc.. Could drill into an electrical or something, never heard of that yet. Also, carpet caught in the drill and causing a huge run.... climbing through attic and falling through ceiling. All bad scenarios to think about. If your careful, smart and cautious you'll be ok, but some guys just don't think things through.
Make sure to silicone all penetrations too... that kind of stuff.
Unfortunately there are just some people waiting to sue. I did have one lady one time try to claim roof damage. It turned out that she just wanted out of her contract w/E*. I went out to inspect it myself. She wasn't there. Got up on my ladder and took tons of pics. The line from the dish had already been cut and the cable company tied into it. Obviously she switched to cable and was just looking for E to pay her some money or cancel her. Luckily that install was beautiful. Dish was mounted to overhang way out from any living space and plenty of pitch/patch all under mast footplate. No way that thing was leaking at all. Sent in the pics to damage claim office and never heard a word again.
