    Using a drilling machine, make holes in the boundaries of the skylight frame on the opposite side. Now chalk the boundaries of the skylight on the roof, where you plan to install it. Now remove the tiles where you will install the skylight. For that purpose, you can use pry bar. Make sure you do not break the tiles, as they will be used later after the skylight is installed in the garage ceiling. Now install blocks at the inner side of the point where you will place the skylight.

    Take a circular saw and use it to cut the roof, from the chalked area that you marked earlier. Then insert the screws in the piece you cut, which will be used to take off the piece from the roof. Now place the skylight at the hole that you created. You can use spacers or positioning blocks in order to center the new skylight that you are installing.

    Now, you can secure the skylight from the outer side, by nailing the center of the skylight bracket. Place the tiles around the skylight after cutting them according to the needs. The flashing of the skylight will be enough to stop the rain water to penetrate from the sides of the skylight.
