Skylights are a beautiful way to bring natural light into your home, improve energy efficiency, and enhance interior spaces. But like any part of your roofing system, skylights can develop problems over time. Knowing what to look out for — and how to address it — can help prevent long-term damage and costly repairs.

Here are six common skylight issues homeowners may face and how to properly fix them.

1. Leaking Around the Skylight

One of the most frequent skylight issues is water leaking around the frame or into the ceiling below. Leaks often occur due to:

How to Fix It:
The first step is identifying the source of the leak. G Roofing’s skylight repair services include assessing the flashing and sealant and making necessary repairs to stop the water intrusion. If the damage is extensive, a full skylight replacement may be recommended.

2. Condensation Buildup

Moisture forming inside or around the skylight, especially in colder months, can be a sign of poor insulation or ventilation. This is particularly common in kitchens and bathrooms where humidity is higher.



How to Fix It:
Improving airflow and ventilation in the affected room can help reduce condensation. If the skylight’s seals are failing, a professional may recommend resealing or replacing the unit.

3. Cracked or Damaged Glass

Skylight glass can crack due to weather events, fallen debris, or age-related stress. Even small cracks can allow moisture into the home and reduce the energy efficiency of the skylight.

How to Fix It:

Cracked skylights often require full replacement. G Roofing provides professional skylight replacements using durable, high-quality products that match your existing setup.

4. Discolored or Foggy Skylight Glass

Over time, skylight glass can become cloudy or stained due to mineral deposits, seal failure, or age. This affects both appearance and natural light flow.

How to Fix It:

If the discoloration is caused by failed seals in a double-pane skylight, the unit may need to be replaced. A clear, properly sealed skylight restores both appearance and function.

5. Faulty Flashing

Flashing is the waterproof barrier installed around the skylight to protect against leaks. If it becomes loose, corroded, or improperly sealed, it can let water seep in and cause interior damage.

How to Fix It:

G Roofing replaces or repairs damaged flashing as part of our skylight leak repair process. Ensuring the flashing is correctly installed is critical to long-term performance.

6. Skylight Is Outdated or Inefficient

Older skylights may not offer the same energy efficiency as newer models. They might lack low-emissivity (Low-E) coatings, proper insulation, or modern sealing technology.

How to Fix It:

If your skylight is more than 15 to 20 years old, it may be time to consider a replacement. G Roofing installs high-quality skylights with updated energy-efficient features to help reduce heat loss and improve indoor comfort.
