  • Glass rooflights installed in flat roof applications can be more susceptible to staining and discoloration through rain water and other contaminants such as bird droppings, tree sap and pollutants from vehicle exhausts. Therefore, just like any other window in your home, regular cleaning and periodic inspection of the units is recommended to maintain their performance over time.

    Installing your rooflight at the correct pitch will go a long way to keeping the glass clean as this helps rainwater run off the surface naturally, but there are other things you can do that will improve the lifespan and look of your rooflight. Let’s discuss good old fashioned cleaning first.

    What cleaning products should I use?

    Any standard glass-cleaning product can be used to clean your rooflight; the best method of cleaning is by regularly washing the glass using a solution of warm water and mild detergent. All surfaces should be cleaned using a soft cloth or sponge, using nothing harsher than natural bristle brushes. If atmospheric pollution has resulted in heavy soiling of the glass, then nothing harsher than white spirit should be used.

    It is important to note that under no circumstances should chlorinated hydrocarbons, esters, ketones or abrasive cleaners be used. If any of these are used, it may affect the powder coated frame and glass finish of your rooflight.

    How often should the rooflight be cleaned?

    This will typically depend upon its shape, pitch and location; however it is recommended that a general inspection is carried out at least once every 6 months.

    What is self-cleaning glass?

    Some rooflights feature specialist coated glass referred to as ‘self-cleaning glass’. This is a great product that uses an organic process to break down dirt using natural daylight, which is then washed away by rain. Any water that hits the glass tends to sheet off rather than form droplets on the surface, which then evaporates and leaves dirt behind.

    Self-cleaning glass for flat roof rooflights

    The problem with self-cleaning glass is that a minimum pitch of 30 degrees is recommended by the manufacturers in order for it to be effective, so this type of technology is not ideally suited to flat roof applications where a pitch of 3-5 degrees is far more common.

    There are alternative treatments which are available however that are much more suited to use with flat roof applications. EnduroShield is an invisible, non-stick coating that reduces cleaning time by up to 90%. Application is a simple process of spraying the liquid coating onto a clean surface to provide a permanent protective bond. With EnduroShield, the use of harsh chemicals is eliminated. Due to the reduction in cleaning, you use less water, so the benefit to the environment is cumulative and ongoing.

    You will still need to periodically clean your rooflights, even with the EnduroShield system applied, but cleaning is less frequent and much easier when carried out.

    The glass can be cleaned using normal products and methods; no special cleaning products are required and the finish can last for years depending on atmospheric conditions and exposure to pollutants.
