Does Your Skylight Need Repairs?

Skylights add natural light and a touch of elegance to any home, but like any other part of your property, they require proper maintenance to ensure they stay in good shape. Over time, skylights may develop issues that, if left unattended, can lead to more significant problems. However, these issues often go overlooked by homeowners. That’s why it’s important to know the signs that indicate your skylight needs repairs.

Signs Your Skylight Might Need Repairs

Keep an eye out for the following signs that indicate your skylight needs to be repaired:


One of the most apparent signs that your skylight requires attention is water leakage. If you notice water stains on your ceiling or walls near the skylight, it’s crucial to investigate promptly. Leaks can result from damaged flashing, worn-out seals, or even cracks in the skylight itself.


Excessive condensation on the interior of your skylight can indicate a problem. While some condensation is normal, persistent moisture could be a sign of poor insulation or a faulty seal. This can lead to mold growth and compromise the structural integrity of your skylight over time.

Visible Damage

Inspect your skylight for visible damage, such as cracks, chipped glass, or broken seals. Physical damage can compromise the skylight’s ability to keep out the elements and can lead to further issues if left unaddressed.

Drafts & Temperature Fluctuations

If you notice drafts around your skylight or experience significant temperature fluctuations, it may be an indication of a seal failure. This not only affects your comfort but also impacts energy efficiency, leading to increased heating and cooling costs.

Aging & Wear

If your skylight is older than 15 years, the sealant may start to degrade, which can lead to drafts and moisture infiltration. Older skylights may also start to yellow, so make sure to inspect your skylights as they age.

When To Choose DIY vs. Professional Repairs

Once you’ve identified signs of skylight damage, the next step is to determine whether you can handle the repairs yourself or if it’s time to call in a professional.

DIY Repairs

With any DIY repairs, you need to have some baseline knowledge and experience before jumping in. For skylights, you’ll often have to work on a ladder or on the roof, so make sure this is something you are comfortable with before opting for the DIY route.

Some situations that can be fixed by the homeowner include:

  • Seal replacement: If the issue is a worn-out seal, it’s a relatively simple DIY fix. Purchase a replacement seal from your local hardware store and follow the manufacturer’s instructions to ensure it’s properly installed.
  • Small crack repair: For small cracks in the skylight glass, you can use a clear epoxy or silicone sealant to fill the gaps. Ensure the area is clean and dry before applying the sealant, and follow the product guidelines.
  • Cleaning & maintenance: Regularly cleaning and maintaining your skylight can prevent many issues. Remove debris, clean the glass, and inspect for any visible damage.

Professional Repairs

The following types of repairs are more complex and best left to the professionals to ensure the job is done correctly and safely:

  • Flashing replacement: If the flashing around your skylight is damaged, it’s best to call a professional. Flashing plays a crucial role in preventing water infiltration, and improper repairs can lead to more significant issues.
  • Large cracks or structural damage: If you notice significant cracks or structural damage, it’s essential to bring in a professional. Attempting to repair major damage without the necessary expertise could result in further complications.
  • Replacing the skylight: If your skylight is outdated or the damage is extensive, it might be more cost-effective to have it replaced. Professional installers can ensure the new skylight is properly fitted and sealed, providing long-lasting results.

Addressing Skylight Problems

Regularly inspecting your skylight is crucial to preserving it and preventing costly repairs. While some minor issues can be addressed through DIY methods, it’s important to recognize when professional intervention is necessary. Prompt attention to skylight problems will not only extend the life span of the fixture but also contribute to a healthier and more comfortable living environment. Remember, if in doubt, it’s always wise to seek the expertise of professionals to ensure the longevity and efficiency of your skylight.
