Maintenance and Care of Conservation Rooflights

Conservation rooflights are a popular choice for those who want to preserve the traditional appearance of their property while still enjoying the benefits of natural light. They are typically made from high-quality materials such as glass, timber, and metal, and require regular maintenance to keep them in top condition. In this blog, we’ll cover the maintenance and care of conservation rooflights, including cleaning, inspection, and repair.

Cleaning conservation rooflights

Regular cleaning is essential to keep your conservation rooflights looking their best and functioning properly. Here are some tips for cleaning your rooflights:

Use a soft, non-abrasive cloth or sponge and a mild detergent solution to clean the glass.

Avoid using abrasive cleaners or scrubbers that can scratch the glass or damage the sealant around the frame.

Clean the frames with a damp cloth and a mild detergent solution. Avoid using harsh chemicals that can damage the paint or finish on the frame.

Remove any dirt or debris that has accumulated in the channels or tracks with a soft brush or vacuum. If your conservation rooflight has a glazing bar, then ensure you take particular care to clean down the edges as moss and other debris can collect around this area.

Inspecting your rooflight

Regular inspection of your conservation rooflights is crucial to identify any issues early on and prevent them from developing into more significant problems. Here are some tips for inspecting your rooflights:

Check the glass for any cracks, chips, or scratches that could compromise its integrity or affect its performance.

Inspect the frame and sashes for signs of wear, such as rust or corrosion, and repair or replace as necessary.

Check the weather seals around the frame to ensure they are intact and functioning properly. Replace any damaged or worn seals.

Make sure the hardware, such as hinges and locks, are in good working order and lubricate them if necessary.

Repairing a conservation rooflight

If you notice any issues during your inspection, it’s essential to address them promptly to prevent further damage. Here are some tips for repairing your conservation rooflights:

For minor issues such as small cracks or chips in the glass, you can use a glass repair kit to fill the damaged area. However, for larger cracks or chips, it’s best to replace the glass.

It is important to note that all Stella rooflights are made using 316L stainless steel, which means they will not rust. If, however, you have purchased mild or carbon steel rooflights they may rust over time. If you notice any signs of rust or corrosion on the frame, sand the affected area and repaint it with a rust-inhibiting primer and topcoat.

Replace any damaged or worn weather seals to ensure the frame is properly sealed against the elements.

If you notice any hardware issues, such as a loose hinge or lock, tighten or replace the hardware as necessary.

Other considerations for maintaining conservation rooflights

Roof windows are often positioned in difficult to reach places, high up in the roof of a property, which can make regular maintenance and cleaning difficult. If this is the case, then you should ensure that your conservation rooflights are made from stainless steel (especially if you live near the coast) as this will help protect the frame from rust.

All conservation rooflights should also come with a high quality paint or powder coat to protect the frame underneath. These coatings, however, are no substitute for the quality of the frame material and can easily get scratched or damaged, exposing the metalwork.  

Your rooflight manufacturer should provide you with guidance relating to the specific maintenance requirements for their product. It is important to realise that failing to adhere to the manufacturers recommended maintenance guidelines and cleaning schedules may invalidate your products warranty.


In conclusion, regular maintenance and care of your conservation rooflights are essential to keep them in top condition and ensure they function correctly. By following these tips for cleaning, inspection, and repair, you can prolong the lifespan of your rooflights and enjoy the benefits of natural light in your home for years to come.
