You might want to check the sealant around the base of the antenna, where it is attached to the roof. I think I see about a one inch long crack in the sealant at the base -- but the photograph may just make it look that way.
Since the wind was strong enough to break that aluminum tubing, there's a possibility some of the screws that hold the base to the roof pulled loose, too -- does the base seem to be firmly attached to the roof?
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
