Whether electric or manual, sunroofs exist in a variety of sizes and styles. While some car owners choose to purchase vehicles with sunroofs already installed, other drivers may choose the aftermarket option.
Car engineers design the roof of the car around the factory-installed sunroof and make specific adjustments to ensure the most watertight seal possible. Installing an aftermarket sunroof requires cutting a hole in the roof and headliner. This predisposes the aftermarket sunroof to leakage.
Drainage tubes blocked by leaves or dirt commonly cause leaks. Wipe the troughs of the sunroof down with a wet rag and blow compressed air through the tubes to clear away any blockages. Leaking rubber seals or improperly installed sunroofs require a visit to a sunroof installation shop
Ask about warranties on any work completed by the sunroof installer. Make sure to get the warranty in writing. Inquire with your vehicle manufacturer as to whether or not the installation of an aftermarket sunroof voids the warranties for any part of your vehicle.
