Skylight Repair: Top 5 Common Issues

Skylights bring natural light, fresh air, and architectural beauty into your home, but when something goes wrong, it can lead to frustrating leaks, drafts, or even water damage. If you’re noticing signs of wear or performance issues, it’s time to consider skylight repair before minor problems become major expenses. At M&M Skylights, we specialize in diagnosing and fixing skylight issues quickly and professionally.

Here are the five most common skylight problems—and how we solve them.

 

1. Leaking Around the Skylight

How it happens:

Improper flashing, old sealant, or weather damage can cause water to seep in around the skylight, especially during heavy rain or snow melt.

Our fix:

We inspect the entire skylight system, including flashing and surrounding roofing materials. Our team reseals or replaces flashing and ensures the waterproofing system is intact to prevent future leaks.

 

2. Cracked or Foggy Glass

How it happens:

Over time, skylight glass can crack due to hail, fallen branches, or thermal stress. Double-paned glass may also become foggy if the seal between panes fails.

Our fix:

We offer high-quality glass replacements that match your existing skylight size and style. In most cases, we can upgrade to energy-efficient, low-E glass to improve insulation and reduce heat gain.

 

3. Condensation Build-Up

How it happens:

Poor ventilation or insulation can cause warm, moist air to collect on the interior surface of the skylight, leading to condensation and even mold growth.

Our fix:

We assess the ventilation system and the placement of the skylight. Adding a vented skylight or improving attic airflow can help resolve this issue, while proper insulation around the unit helps reduce temperature differences.

 

4. Mechanical Failures in Operable Skylights

How it happens:

Manual or electric skylights that open and close can suffer from motor issues, broken cranks, or worn-out hinges over time.

Our fix:

M&M Skylights services both manual and automated skylights. We can repair or replace faulty hardware, restore motor function, or upgrade older units with smart home integration for easy control and convenience.

 

5. Roofing Damage Around the Skylight

How it happens:

Improper installation, aging shingles, or roof damage near the skylight can lead to water infiltration or structural issues.

Our fix:

We inspect the roof around your skylight to ensure everything is sealed and structurally sound. If needed, we coordinate repairs to the surrounding roof to protect both your skylight and home.
