Step 1
Open the sunroof to check for leaks when you are shopping for a used vehicle. First of all, make sure the sunroof opens smoothly and closes securely. A good, snug fit with no cracks or lop-sided setting is a good indication that it won't leak.
-
Step 2
Look carefully around the inside edges of the roof of the car where the sunroof opens. Check a sunroof for leaks by making sure there are no signs of rust or corroded metal around the opening edges. Of course, examine this area while the sunroof is open so that you see all areas on the sunroof opening's edges.

Step 3
Check the ceiling inside the vehicle when you check a sunroof for leaks. Look for signs of water stains around the inside ceiling lining of the car at the sunroof's site. Ceiling fabric at the site of the sunroof or around the area of the sunroof that looks spotted or has slight color variations may indicate a sunroof leak.
-
Step 4
See if the car's headliner (the ceiling fabric) is sagging. A leaking sunroof may cause water to run inside the headliner. Water buildup causes the headliner to sag over time.
-
Step 5
Examine the floor of the vehicle carefully when you check a sunroof for leaks. Damp carpet or a mildew smell may indicate a leaking sunroof. Also, look for water stains on seats where water may drip down from the sunroof.
