How do I prevent condensation under my aluminum carport?

by Theresa

I have a 25 year old aluminum car port. Overnight when my car is parked, water drips down wherever there is a screw connecting the top to the frame. It doesn’t leak at all when it rains. Only at night the dripping( maybe condensation) comes down the frame and falls on the car. Could I use clear caulking on screws on roof top to seal?
