Signs that Your Skylight is Leaking

Spotting a skylight leak in its early stages can save you from costly repairs. Some common warning signs include:

Water Stains Around the Skylight Frame

Brown or yellowish stains on the ceiling or drywall around your skylight are a clear indication of water infiltration.

Slicking Water in a Rain Shower  

A leak in the flashing or seal is likely to be blamed if water is dripping from your skylight during a rain shower.  

Condensation Build-Up  

A leak is the likely cause if there is an overabundance of moisture between the glass panes or around the interior frame, since some condensation is expected.  

Drafts and Cold Spots  

If cold air is being felt and there is also water, the same gaps are the most likely to be to blame. Such gaps and leaky skylights are a common problem, often causing damage to the insulation.  

Mold or Mildew Growth  

Leaks can encourage persistent dampness, and the mold can spread rapidly to nearby drywall or insulation.  

As a homeowner, identifying the above problems can save you from encountering more expensive issues, such as a ceiling collapse or rot in the structural wood.

How to Fix a Leaking Skylight?

If you’ve identified a skylight leak, acting quickly is essential. Depending on the severity of the problem, here are several ways to fix it:

  • Check the Flashing

The skylight is flashed and features a metal barrier that seals it to the roof. Flashing may weaken, slide, or wear out over time as weather changes are typical in Long Island. Leaks are typically addressed by resealing or replacing the flashing.

  • Seal Cracks and Gaps

Leaks can be caused by minor cracks in the skylight’s frame or around the glass. Seal these gaps with a high-quality, waterproof sealant or caulking. Maximum effectiveness is assured by applying it to a dry area.

  • Replace Worn Gaskets and Weatherstripping

Rubber gaskets and weatherstripping around skylights can deteriorate over time. Replacing these components improves both insulation and water resistance.

  • Repair or Replace the Skylight Glass

If condensation or water appears between double-glass panes, it may indicate a broken seal within the skylight itself. In this case, replacing the glass or the entire skylight may be necessary.

  • Clean Clogged Weep Holes

Skylights can be made with small drainage holes (weep holes) that allow water to escape. When dirt, leaves, or debris clog the system, they can lead to water backup and leaks. Proper drainage can be restored by cleaning them.

While homeowners can handle minor fixes, it’s crucial to assess whether the damage is beyond a quick patch job.

How to Prevent Future Skylight Leaks?

Prevention is always better than repair. To protect your Long Island home from skylight leaks, follow these preventive steps:

Schedule Regular Inspections

Have a professional skylight leak repair in Long Island inspect the skylight at least two times a year, even more often depending on the severity of the winters (or heavy storms). Remember to inspect before and after harsh winters or storms.

Maintain Roof Health

Since skylights are integrated into the roofing system, damaged shingles, clogged gutters, or poor roof ventilation can contribute to leaks. Keeping your roof in top shape prevents water intrusion around the skylight.

Keep Skylights Clean

Remove dirt, leaves, and debris regularly to prevent drainage blockages and to spot cracks or seal issues early.

Use High-Quality Skylights

When installing or replacing skylights, invest in high-quality, energy-efficient models designed with durable flashing and double or triple glazing.

Reapply Sealant Periodically

Even the best sealants degrade over time. Reapply waterproof caulking around the frame every few years as preventive maintenance.

Control Indoor Humidity

Excessive indoor humidity can create condensation that mimics a leak. Use dehumidifiers, bathroom fans, and proper ventilation to manage moisture levels inside your home.

Implementing these measures not only prevents leaks but also extends the lifespan of your skylight.

When Should You Call a Professional?

Although certain minor repairs can be handled by DIY, skylights are more complicated, which would require professional help in the following cases:

  • Persistent Leaks Despite Repairs

If you’ve sealed cracks or replaced gaskets but still notice water infiltration, the issue may be deeper within the roof structure.

  • Structural Damage

Water-damaged drywall, sagging ceilings, or rotting wood beams indicate serious problems that require professional repair.

  • Skylight Replacement Needed

Older skylights (15–20 years old) may be better replaced than repaired. A professional can advise whether replacement is more cost-effective.

  • Roof Work Required

If flashing or surrounding roof shingles are the cause of the leak, professional roofing expertise is necessary to ensure the fix lasts.

  • Safety Concerns

Climbing onto roofs can be risky, especially on steep or slippery surfaces. Hiring an expert eliminates safety hazards for homeowners.

Professional skylight contractors in Long Island have the right tools, materials, and knowledge to provide long-term, weatherproof solutions that DIY methods may not achieve.
