Sealing various rooftop objects and their fasteners

Yahoo Message Number: 39851
Hi all,

I'm sure many of you have repaired things that are roof top mounted.
When doing so, what kind of sealer do you find best to use? I used GE Silicone II when replacing a broken Girard anemometer, but I'm not sure that was a good choice.

Thanks,
Paul T.
