Skylight Maintenance: Tips for Keeping Your Skylights in Top Condition

September 12, 20235 min read

Skylights are a fantastic addition to any home, allowing an abundance of natural light to flood your living spaces and providing a unique view of the sky above. They not only enhance the aesthetics of your home but also contribute to energy efficiency by reducing the need for artificial lighting. However, to continue reaping these benefits, it's essential to maintain your skylights properly. In this comprehensive guide, we'll walk you through the ins and outs of skylight maintenance, offering expert tips to keep them in top condition for years to come.

The Importance of Skylight Maintenance

Skylights are a popular feature in modern homes, and while they offer numerous advantages, neglecting their maintenance can lead to a host of problems. Proper maintenance ensures:

  • Prevention of Leaks: Regular inspections and upkeep help identify and address potential sources of leaks before they become significant issues.

  • Reduction of Condensation: Proper ventilation and sealing prevent condensation buildup, which can lead to water damage and mold growth.

  • Longevity: Maintaining your skylights extends their lifespan, protecting your investment and saving you money on replacements.

  • Energy Efficiency: Well-maintained skylights continue to contribute to your home's energy efficiency by providing natural light and reducing the need for artificial lighting.

Now, let's dive into the essential tips for skylight maintenance.

Cleaning Your Skylights

Regular cleaning is the foundation of proper skylight maintenance. Dust, dirt, and debris can accumulate on the surface, reducing the amount of natural light that enters your home. Follow these steps to clean your skylights effectively:

  1. Gather Your Cleaning Supplies: You'll need a bucket, mild detergent, a soft-bristle brush or sponge, a squeegee, and a non-abrasive cloth.

  2. Prepare a Cleaning Solution: Mix a small amount of mild detergent with warm water in the bucket. Avoid using harsh chemicals or abrasive cleaners, as they can damage the skylight's surface.

  3. Access the Skylight Safely: Depending on your skylight's location, you may need a stable ladder or scaffolding. Ensure you follow safety guidelines when accessing the skylight.

  4. Wet the Surface: Gently wet the skylight's surface with the cleaning solution.

  5. Scrub Gently: Use the soft-bristle brush or sponge to scrub away dirt and grime. Be gentle to avoid scratching the skylight.

  6. Squeegee It Clean: Use the squeegee to remove excess water and cleaning solution. Start at the top and work your way down in a continuous motion.

  7. Dry and Polish: Finish by using a non-abrasive cloth to dry and polish the skylight's surface. This step helps prevent streaks and water spots.

  8. Inspect for Damage: While cleaning, take the opportunity to inspect the skylight for any signs of damage or wear.

Inspecting for Damage

Regular inspections are crucial for identifying and addressing potential issues with your skylights promptly. Here's what you should look for during your inspections:

  1. Leaks: Check for any signs of water infiltration around the skylight, such as stains on the ceiling or walls.

  2. Condensation: Examine the interior of the skylight for condensation, which can indicate sealing problems or inadequate ventilation.

  3. Cracks or Chips: Inspect the skylight's glass or acrylic surface for cracks, chips, or other damage that may compromise its integrity.

  4. Sealant Condition: Check the condition of the sealant or flashing around the skylight. Cracked or deteriorating sealant can allow water to penetrate.

  5. Operational Issues: If your skylight is operable, test its opening and closing mechanisms to ensure smooth operation.

  6. Frame and Trim: Inspect the frame, trim, and surrounding roofing materials for signs of deterioration, such as rot or rust.

  7. Skylight Well: If your skylight is in a well, ensure that it is clear of debris and drains properly.

Addressing Common Skylight Issues

If you identify any issues during your inspections, it's essential to address them promptly to prevent further damage. Here's how to deal with common skylight problems:

  1. Leaking Skylights: If you notice water infiltration, identify the source of the leak. It could be a damaged seal, flashing issues, or cracks in the skylight's surface. Address the underlying problem and reseal or replace damaged components as needed.

  2. Condensation: Condensation inside the skylight can be due to poor ventilation or sealing. Ensure the skylight is adequately ventilated, and consider adding a ventilation fan if necessary. If sealing is the issue, reseal the skylight to prevent moisture buildup.

  3. Cracked or Chipped Glass: Small cracks or chips can often be repaired using a specialized skylight repair kit available at home improvement stores. For extensive damage, consider replacing the skylight.

  4. Sealant and Flashing Issues: Cracked or deteriorating sealant or flashing should be replaced promptly to maintain a watertight seal. Clean the area thoroughly before applying new sealant or flashing.

  5. Operational Problems: If your operable skylight has difficulty opening or closing, inspect the mechanisms for obstructions or damage. Lubricate moving parts and replace any worn components.

  6. Frame and Trim Damage: Address any rot or rust on the frame, trim, or surrounding roofing materials promptly. Replace damaged components and ensure proper flashing and sealing.

Regular Maintenance Schedule

To keep your skylights in top condition, consider implementing a regular maintenance schedule. Here's a suggested timetable:

  • Monthly: Inspect the interior for condensation and the area around the skylight for leaks.

  • Quarterly: Clean the skylight's exterior and check for any visible damage.

  • Annually: Conduct a comprehensive inspection, including sealant and flashing checks, and perform a thorough cleaning.


Skylights are a wonderful addition to any home, providing natural light and a unique connection to the outdoors.
