Verification is what separates a quick glass swap from a reliable Subaru Wrx sunroof or panoramic roof repair. After installation, we confirm the panel sits at the correct OEM height and perimeter gaps are uniform. Seals should compress evenly, and trim should sit cleanly without lifting, pinching, or misalignment. We recheck mounts, locating tabs, and fasteners so the glass is not under torsional stress and surrounding components are not forced out of position. We then run the roof system through its full operating range, including vent, open, close, and any express functions, plus sunshade movement where equipped. Many roof modules require initialization after service so the motor establishes end stops and anti-pinch parameters; skipping this can cause hesitation, reversing, or a roof that will not fully close. We verify normal operation and listen for abnormal noise that can indicate misalignment or seal interference. To prevent leaks and callbacks, we perform a controlled water test to confirm water routes into the tray and exits through the drains rather than entering the cabin or pooling at corners. We then share aftercare guidance, recommended cure time where bonding applies, and warranty details. Bang AutoGlass supports the work with a lifetime workmanship warranty and can coordinate with insurance when comprehensive coverage applies.
