Maintaining a skylight is crucial for ensuring its longevity, functionality, and aesthetic appeal. As a skylight supplier, I've seen firsthand the difference proper maintenance can make. In this blog, I'll share some practical tips on how to maintain a skylight effectively.
Regular Cleaning
One of the most basic yet essential steps in skylight maintenance is regular cleaning. Over time, dirt, dust, leaves, and other debris can accumulate on the skylight's surface, obstructing sunlight and potentially causing damage. Depending on your location and the environmental conditions, aim to clean your skylight at least twice a year.
For most skylights, a simple solution of mild dish soap and warm water is sufficient. Use a soft sponge or cloth to gently wipe the surface, avoiding abrasive materials that could scratch the glass or plastic. Rinse thoroughly with clean water to remove any soap residue.


If your skylight has stubborn stains or bird droppings, you may need to use a specialized cleaner. However, be sure to read the manufacturer's instructions carefully and test the cleaner on a small, inconspicuous area first to avoid damage.
When cleaning the exterior of the skylight, it's important to take safety precautions. Use a sturdy ladder and ensure it is properly secured. If you're not comfortable working at heights, consider hiring a professional window cleaning service.
Inspecting for Damage
Regular inspections are another key aspect of skylight maintenance. Look for any signs of cracks, chips, or leaks in the glass or frame. Check the seals around the skylight for any gaps or damage, as these can allow water to seep in and cause water damage to your ceiling and walls.
If you notice any damage, it's important to address it promptly. Small cracks or chips can often be repaired using a clear epoxy or a specialized glass repair kit. However, if the damage is extensive, you may need to replace the skylight.
In addition to visual inspections, pay attention to any changes in the performance of your skylight. If you notice a decrease in sunlight or an increase in drafts, it could be a sign of a problem. Contact a professional skylight installer or repair technician to diagnose and fix the issue.
Lubricating Moving Parts
If your skylight has any moving parts, such as hinges or vents, it's important to lubricate them regularly to ensure smooth operation. Use a silicone-based lubricant to prevent rust and corrosion and to keep the parts moving freely.
Apply the lubricant to the hinges, tracks, and other moving parts according to the manufacturer's instructions. Be careful not to over-lubricate, as this can attract dirt and debris and cause the parts to stick.
Maintaining the Surrounding Area
The area around your skylight also plays an important role in its maintenance. Keep the roof and gutters clean and free of debris to prevent water from pooling around the skylight. Trim any overhanging branches that could scratch or damage the skylight.
In addition, make sure the flashing around the skylight is in good condition. Flashing is a thin metal strip that is installed around the skylight to prevent water from seeping in. If the flashing is damaged or loose, it can allow water to penetrate the roof and cause water damage.
Different Types of Skylights and Their Maintenance
There are several different types of skylights available, each with its own unique maintenance requirements. Here are some tips for maintaining the most common types of skylights:
- Acrylic Dome Skylight: Acrylic dome skylights are lightweight, durable, and resistant to impact. They are also relatively easy to clean and maintain. To clean an acrylic dome skylight, use a mild soap and water solution and a soft cloth. Avoid using abrasive cleaners or materials, as these can scratch the surface of the acrylic.

- PC Skylight: PC (polycarbonate) skylights are another popular option. They are lightweight, shatterproof, and offer excellent insulation. To clean a PC skylight, use a mild soap and water solution and a soft cloth. Avoid using abrasive cleaners or materials, as these can scratch the surface of the polycarbonate.

- Polycarbonate Dome Skylight: Polycarbonate dome skylights are similar to acrylic dome skylights but offer greater strength and durability. They are also resistant to UV rays and can withstand extreme temperatures. To clean a polycarbonate dome skylight, use a mild soap and water solution and a soft cloth. Avoid using abrasive cleaners or materials, as these can scratch the surface of the polycarbonate. For more information on polycarbonate dome skylights, visit Polycarbonate Dome Skylight.
