Roof skylights or roof windows are installed in the ceilings to provide natural light and ventilation. With these structures, the only concern is maintenance. If you have a tall ceiling, being able to reach out to these skylights for regular cleaning can be quite a task. Here a few tips that can simplify your task. There are various tools available to make these skylights easier to reach. You can use window ladders that are specially designed to provide a stable and safe means of obtaining the required elevation. If you have a roof that is very high, you can even make use of man lifts. You have the option of creating a scaffolding which is a temporary structure meant to help your reach the skylight windows. The man lift and the scaffolding are usually used by professionals. Once you have reached the skylight, all you need to do is clean out all the debris from the frame of your skylight. Once done, you can simply wipe the glass off with soap water and rinse it with normal water. If you think that the skylight is too dirty, washing it thoroughly is also a good idea. Keeping skylights clean improves the quality of light and air that enters your space.
