Gurus,

I am on a hunt for water leaks on my roof.  I have to admit that I have neglected my roof but that is about to change.

I am tempted to just remove all these warts and then see what does not work.  But cooler heads recommend that I identify them before removing.

So...Can you identify these things?  And do you have a recommended procedure for patching the holes that will be left behind? 

 (There is an odd shaped little black device on the passenger side that I would think would be an XM antenna, but there is another for-sure XM antenna farther back.  

Thanks,
Bill
