In one of my rooms I have three sets of sliding glass doors facing
the patio and I am worried that in driving rain down here in Miami
during the hurricane season with rain blasting on the glass door and
flowing downward it will fill up the door track and water may intrude.

I am thinking of building up the inside "fin" of these tracks. I
know the part that the roller sits on they sell a strip of metal that
clips on to the original part to reinforce a damaged fin. Can I use
the same part to build up the interior fin and caulk to edges to make
it less likely for water to get in when it's raining like that?

It has not happened yet with real rain but when I use a garden hose
to wash the doors there are some water coming in.

Can't you provide drainage for the track?
