How to Spot Common Skylight Problems

 

Skylights are a fantastic addition to any home. They let in natural light, brighten up dark spaces, and can even help with heating costs in the winter. However, like any part of your home, skylights can develop problems over time. Knowing how to spot common skylight issues can save you a lot of trouble and money in the long run. Here’s a simple guide to help you identify and address common skylight problems.

1. Leaks and Water Damage

One of the most common problems with skylights is leaking. If you notice water dripping from your skylight or see water stains on the ceiling around it, you likely have a leak. Leaks can be caused by several factors, including:

  • Worn Seals: The seals around your skylight can wear out over time, allowing water to seep in.
  • Improper Installation: If the skylight wasn’t installed correctly, it might not be sealed properly.
  • Damaged Flashing: Flashing is the material that surrounds your skylight and helps keep water out. If it’s damaged, water can get in.

To check for leaks, look for signs of water damage around your skylight, especially after a rainstorm. If you find any, it’s time to call a professional to assess and fix the problem.

2. Condensation

Condensation is another common issue with skylights. It happens when warm, moist air inside your home meets the cold glass of the skylight, causing water droplets to form. While a little condensation is normal, too much can lead to mold and mildew, which can damage your home and affect your health.

To reduce condensation:

  • Increase Ventilation: Use exhaust fans in bathrooms and kitchens to remove excess moisture.
  • Use a Dehumidifier: A dehumidifier can help reduce the humidity levels in your home.
  • Insulate Your Skylight: Proper insulation can help prevent the temperature differences that cause condensation.

3. Cracks and Chips

Cracks or chips in the skylight glass can happen due to various reasons, such as hail, falling branches, or even thermal stress (when there’s a significant temperature difference between the inside and outside). Small cracks can grow over time, leading to leaks and more significant damage.

To spot cracks, inspect your skylight regularly, especially after severe weather. If you find any cracks or chips, it’s best to have them repaired or replaced as soon as possible to prevent further damage.

4. Drafts

If you feel a draft near your skylight, it’s a sign that the seal around it is compromised. Drafts can make your home less energy-efficient, leading to higher heating and cooling costs. They can also make your home less comfortable.

To check for drafts, hold your hand near the edges of the skylight on a windy day. If you feel cold air coming in, it’s time to check the seals and insulation around the skylight.

5. Discoloration

Discoloration of the skylight glass or the area around it can indicate several problems:

  • Water Damage: Yellow or brown stains around the skylight can be a sign of water damage.
  • UV Damage: Over time, UV rays can cause the skylight glass to become discolored or cloudy.
  • Mold or Mildew: Black or green spots can indicate mold or mildew growth, usually due to excess moisture.

Inspect the area around your skylight regularly for any signs of discoloration. If you notice any, it’s essential to address the underlying issue to prevent further damage.

6. Difficulty Opening or Closing

If your skylight can be opened and closed, make sure it operates smoothly. Difficulty in opening or closing the skylight can be a sign of several problems, including:

  • Warped Frame: The frame around the skylight can warp due to moisture or temperature changes, making it difficult to open or close.
  • Broken Mechanism: The opening mechanism can wear out over time and may need to be repaired or replaced.
  • Debris: Leaves, dirt, or other debris can get stuck in the mechanism, preventing smooth operation.

Regularly clean and inspect the skylight to ensure it opens and closes properly. If you encounter any issues, it’s best to have a professional take a look.

7. Cloudy or Foggy Glass

If your skylight glass looks cloudy or foggy, it’s a sign that the seal between the panes of glass is broken. This can allow moisture to get in between the panes, reducing the clarity of the glass and potentially leading to further damage.

To spot this issue, look for condensation or fogging that doesn’t go away, even on dry days. If you notice this, the glass will likely need to be replaced.

8. Worn or Damaged Flashing

Flashing is the metal or plastic material that helps direct water away from the edges of the skylight. Over time, flashing can become worn or damaged, leading to leaks and water damage.

To check the flashing, look for:

  • Rust or Corrosion: Metal flashing can rust or corrode over time, especially if it’s not properly maintained.
  • Cracks or Gaps: Any cracks or gaps in the flashing can allow water to seep in.
  • Loose Flashing: Flashing that’s not securely attached can be blown away in strong winds, leaving your skylight vulnerable.

Inspect the flashing around your skylight regularly, especially after severe weather. If you notice any issues, it’s important to have the flashing repaired or replaced.

9. Moisture in the Attic

If you have an attic, check for signs of moisture or water damage in the area around your skylight. This can include:

  • Wet Insulation: If the insulation around your skylight is wet, it’s a sign of a leak.
  • Water Stains: Look for water stains on the attic floor or roof deck.
  • Mold or Mildew: Any signs of mold or mildew in

the attic can indicate a moisture problem, often stemming from a leak in the skylight or its surrounding area.

10. Rust or Corrosion

If your skylight has metal components, such as the frame or flashing, check for signs of rust or corrosion. These can weaken the structural integrity of the skylight and lead to leaks or other issues. Rust can often be spotted by looking for reddish-brown stains or flaking metal.

11. Peeling Paint or Wallpaper

Inside your home, check the area around the skylight for peeling paint or wallpaper. Moisture from a leaking skylight can cause paint and wallpaper to bubble, peel, or blister. This is a clear sign that water is entering your home and needs to be addressed.

12. Roof Shingle Damage

Inspect the roof shingles around the skylight. Damaged or missing shingles can expose the skylight to water infiltration. Look for signs of shingle wear and tear, such as cracks, curling, or missing shingles. Maintaining the shingles around your skylight can help prevent leaks.

13. Skylight Glazing Issues

The glazing on your skylight is the coating or sealant that helps keep it waterproof. Over time, glazing can deteriorate, leading to leaks or drafts. Check for any cracks or gaps in the glazing, and if you find any, consider having the skylight reglazed by a professional.

14. Pest Infestation

Small gaps or cracks around your skylight can provide an entry point for pests, such as insects or rodents. If you notice an increase in pests around your skylight, it could be a sign that it’s not properly sealed. Check for any openings and seal them to keep pests out.

15. Structural Movement

Homes settle and shift over time, which can affect the fit and alignment of your skylight. If you notice that your skylight seems out of place or misaligned, it could be due to structural movement. This can cause gaps and leaks, so it’s important to have it inspected by a professional.

16. Noise

If your skylight starts to make unusual noises, such as creaking or popping, it could be a sign of structural issues or thermal expansion and contraction. These noises can indicate that the skylight is under stress and may need attention.

17. Fading or Discoloration Inside the Home

Furnishings, carpets, and other items inside your home can fade or discolor due to prolonged exposure to sunlight through a skylight. While this isn’t a structural issue, it’s something to be aware of. Using skylight shades or UV-blocking films can help protect your interior.

18. Poor Skylight Performance

If your skylight doesn’t seem to be performing as well as it used to—such as letting in less light or not ventilating properly—it might be time for an inspection. Over time, wear and tear can reduce the effectiveness of your skylight.

19. Staining on Skylight Glass

Staining or discoloration on the skylight glass itself can be a sign of hard water deposits, pollution, or other environmental factors. Regular cleaning can help maintain the clarity of your skylight, but persistent stains might require professional attention.

20. Increased Heating or Cooling Costs

If you notice a sudden increase in your heating or cooling costs, it could be due to poor insulation around your skylight. A poorly insulated skylight can let heat escape in the winter and let heat in during the summer, making your HVAC system work harder.

Conclusion

Regularly checking your skylight for these common problems can help you catch issues early and prevent costly repairs down the road. Skylights are a wonderful feature in any home, but they require maintenance and care to function properly.
