Wet patch on my Innova's roof-lining: Probable causes & its fix

Have been driving in some extreme rains over the past 2 days, hoping this is something minor.

BHPian jkrishnakj recently shared this with other enthusiasts.

I was driving in some extreme rains over the past two days. I notice a small patch of wetness in the roof lining. This is just above the third row seats.

I’m hoping this is something minor. For now, there is a dent in my peace of mind.

Here's what BHPian Turbanator had to say on the matter:

Is this behind the driver's side or the other? There used to be a coil in the rear, can try switching off the rear AC and see if this is to do with condensation or any blockage. Haven’t heard about the leaking Innova roof.

Here's what BHPian jav had to say on the matter:

The rear AC is on the right side and almost at the bottom and this damp spot looks like it's on the left top so I doubt its related to the rear ac, the only thing that I can think of is the roof shark fin antenna might have a slight gap so get that checked out too on your visit to the service centre.

Here's what BHPian sridhu had to say on the matter:

Never heard of a roof leak in an Innova!

Having said that, this is really weird. Have you checked if there is any debris like leaves in the channel below the hatch hinges? Or the roof trim (this is a clip-on AFAIK)

Have you, by any chance, installed any roof rack or garnish outside?

I would get it checked for both your and the car's health. (Dampness can cause fungus)
