How to Deal with Roof Leaks Around Skylights

May 23, 2025

Skylights can flood your home with natural light, but when they start to leak, they can also bring unwanted headaches. How to deal with roof leaks around skylights is a critical topic every homeowner with skylights should understand—especially if you live in areas prone to heavy rain or fluctuating weather.

Let’s break down why skylight leaks happen, how to spot them early, and what you can do to fix and prevent them.

Why Roof Leaks Around Skylights Happen

Leaks around skylights can be caused by several factors, including:

  • Improper installation: If the skylight wasn’t correctly sealed or flashed, water can easily seep in.
  • Worn or damaged flashing: Flashing directs water away from seams; if it’s cracked or corroded, leaks will follow.
  • Old skylight seals: Over time, skylight seals and caulking can deteriorate due to UV exposure and weather changes.
  • Roof damage nearby: Leaks may also stem from damaged shingles or roofing materials surrounding the skylight.

Signs You Have a Leak Around a Skylight

Be on the lookout for these warning signs:

  • Water stains or discoloration on the ceiling or walls near the skylight
  • Damp spots, dripping water, or visible mold around the skylight interior
  • Bubbling paint or peeling drywall below the skylight
  • Condensation between the skylight panes (may indicate seal failure)

If you notice any of these, it’s time to act fast!

How to Deal with Roof Leaks Around Skylights

1. Inspect the Flashing and Sealant

Start by visually checking the flashing around your skylight. Look for:

  • Cracked, rusted, or loose flashing
  • Missing or deteriorated sealant
  • Gaps between the skylight and roof materials

If you find damage, you may need to reseal or replace the flashing entirely.

2. Clear Debris

Leaves, branches, and dirt can trap moisture and force water into small gaps. Regularly remove debris from around the skylight and gutters to prevent pooling.

3. Reseal or Caulk

Use a high-quality, weatherproof roofing sealant to re-caulk any visible gaps. Focus on:

  • The edges where the skylight meets the roof
  • Any cracked or peeling caulk previously applied

This is a temporary fix, but it can hold off further damage until professional help arrives.

4. Call a Roofing Professional

Persistent leaks or structural issues require expert attention. A licensed roofer can:

  • Re-flash or replace the skylight
  • Address underlying roof damage
  • Ensure proper waterproofing and insulation
