Sunroofs can be permanently sealed with relatively light effort.

  1. 1

    Go to a local junkyard and find a car that is a similar make and model to yours. If you cannot find a compatible vehicle, at least make sure that the vehicle you do select has a roof with comparable contours to your own.

  2. 2

    Measure the dimensions of your car's sunroof and record them. Then use a marker or crayon to mark these dimensions on a smooth, flat area of the junkyard car's roof.

  3. 3

    Use a band saw to cut out a sunroof-sized square from the junkyard car's roof. Be sure you are wearing a mask, gloves and thick clothing.

  4. 4

    Open your car's bonnet, find your car's battery and disconnect the battery's wires from the car using a pair of pliers.

  5. 5

    Open your sunroof. You will see a wire emerging from under your car's roof-lining. Unplug it from the sunroof.

  6. 6

    Stick a chisel or wedge behind the sunroof's lining and pry it off of the sunroof. Peel all of the lining off.

  7. 7

    Locate the screws that connect the movable portion of the sunroof to the roof of the car. Unscrew them with a screwdriver. Remove the sunroof's movable portion, then pull the static portion of the sunroof upwards, lifting it away from the car's roof.

  8. 8

    Line the opening in the car's roof (where the sunroof used to be) with solder. Do the same to the portion of the junkyard car that you cut away. Weld the metal plate from the junkyard car to your car's roof with a welding gun. Be sure to wear adequate protection and follow all safety guidelines.
