How To Troubleshoot Common Skylight Issues

Skylights are a fantastic addition to any home, allowing natural light to flood your space and providing a beautiful view of the sky. However, like any part of your home, they can sometimes develop issues that need attention. Problems such as leaks, condensation, or poor insulation can arise, affecting both the comfort and functionality of your skylight. Addressing these issues early can save you from more extensive repairs down the line.

Leaks

One of the most common issues with a skylight on the roof is leaks, which can occur for various reasons. The sealant around the skylight may deteriorate over time due to exposure to the elements, leading to water penetration. Additionally, flashing or the frame might become damaged, allowing water to seep in. If you notice water spots on your ceiling or walls around the skylight, check the seals for gaps or cracks and replace any worn-out materials.

Condensation

Condensation inside a skylight is often the result of poor ventilation. When warm, humid air comes into contact with a cold surface, it can lead to the formation of water droplets. This problem can be more pronounced in the winter months. Installing proper ventilation, such as a vented skylight or additional exhaust fans, can help mitigate this issue by allowing air to circulate freely and prevent moisture buildup.

Drafts

If you feel a chill around your skylight, it could be due to inadequate insulation or damaged weather stripping. Gaps around the frame or improper sealing can allow cold air to enter and warm air to escape. To fix this issue, inspect the weatherstripping and seals for any wear or gaps, and consider adding extra insulation around the skylight for better energy efficiency.

Cloudy or dirty glass

Over time, skylight glass can accumulate dirt, grime, and debris, causing it to become cloudy or difficult to see through. To clean the glass, use a mild detergent solution and a soft cloth or sponge. For tougher stains, a glass cleaner designed for skylights can help remove residue without damaging the surface. Ensure to avoid harsh chemicals or abrasive tools that may scratch the glass.

Difficulty opening or closing

If your skylight is difficult to open or close, the mechanism could be jammed or damaged. For manual skylights, check the operating arm or crank to ensure it’s functioning properly. For electric skylights, the motor or wiring may need to be inspected. Lubricating moving parts or replacing faulty components can restore smooth operation and make it easier to use.
