Skylights are a popular way of allowing light into an attic room or an area with a flat-roof that might otherwise need to be lit artificially. To get the best performance from your skylight, you will need to check and clean it regularly.
The first thing you will need to do is clear any build-up of debris, such as dead leaves or twigs. They can stop rainwater from running freely down the roof and draining away. This can cause staining on your roof from the chemicals in the leaves; it can also damage the roof itself. You should do this at least annually, or whenever you notice a build-up around the skylight.
If your skylights have a timber frame with a wood finish, you will need to treat it regularly to keep it in good condition. Make sure the surface is clean and dry, and apply an ordinary varnish from the hardware store (unless the manufacturer's instructions say otherwise). You should do this every four years, unless the skylight is in a position that experiences harsh heat or humidity, in which case it will need treating more often.
Cleaning the glass
The glass itself should be cleaned at least every six months, depending on what kind of area you live in — urban areas will need more frequent cleaning than rural ones. Use a soft clean cloth or a squeegee. Clean water should be good enough for most windows, although you can add a small amount of detergent if necessary. You should not use abrasive cleaners, as this could damage the glass. You should also try not to touch the silicone as this could damage the seal.
Check the hinges
If you hear any squeaking when you open the window, or if the window does not seem to move smoothly, you may need to oil the hinges or other moving parts. This should not happen often though, and it is probably best to leave them alone if no maintenance is needed.
Check for scratches
You should regularly check the window itself for any scratches or cracks, which could lead to further trouble later on. However, you will probably need to get a professional if they need any repairs.
If you take the time to keep your skylights clean and in good repair, they will keep your rooms well lit and ventilated for many years to come.
