Sorry to hear of your frustration

Technically, I don't think installing satellite on the roof would have caused the problem UNLESS it happened to get hit by lightning during install. Not knowing what the Lazy Days work was, hard to say, but most likely the result of the rig being plugged into bad power at either place (wrong polarity - wrong phasing, etc). Even that seems incredible - but I would start looking for other damage, starting at the outside receptacle. Check your fridge, microwave - anything electronic.
