What Should You Do If Your Skylight Is Leaking?

Introduction

Skylights bring natural light into homes, enhancing aesthetics and energy efficiency. However, when a skylight starts leaking, it can lead to costly interior damage, mold growth, and structural deterioration. Understanding why skylights leak and how to address them can save homeowners money and prevent long-term issues.

Immediate Steps to Prevent Damage

If you notice water dripping from your skylight, take the following steps to minimize damage:

• Protect Your Interior: Move furniture, electronics, and other valuables away. Use buckets to collect dripping water.
• Dry the Affected Area: Use towels or fans to dry wet surfaces and prevent mold growth.
• Inspect During Rain: Observe the leak during rainfall to determine if it worsens under heavy rain conditions.
• Check for Condensation: Sometimes, the issue is indoor condensation rather than a true leak.

How to Identify the Source of the Leak

Determining the cause of the leak helps in finding the right solution:

• Condensation vs. Leak: Excess humidity may cause condensation, which mimics a leak. Improve ventilation to reduce moisture buildup.
• Check for Visible Damage: Inspect the skylight for cracks, damaged seals, or loose flashing.
• Examine Roof Structure: Sometimes, nearby roofing problems can cause leaks near skylights.
• Water Stains: Look for discoloration around the skylight or ceiling to determine the leak’s source.

Common Causes of Skylight Leaks

Skylight leaks can occur due to various reasons:

• Poor Installation: Incorrectly installed skylights may have gaps or misalignment, allowing water infiltration.
• Flashing Issues: Damaged or improperly installed flashing around the skylight is a common cause of leaks.
• Old or Worn-Out Seals: Over time, skylight seals degrade due to weather exposure.
• Roof Damage: Nearby shingles or tiles in poor condition can allow water to seep into the skylight structure.
• Improper Maintenance: Debris buildup around skylights can trap moisture and cause leaks.

When to Call a Professional Roofer

Some skylight issues require expert attention. Consider professional repair if:

• The leak persists despite DIY solutions.
• You notice structural damage or extensive flashing issues.
• The skylight is outdated and requires replacement.
• There is severe water damage inside your home.
• The leak occurs frequently, even in light rain.

Hiring a professional roofer ensures the problem is properly diagnosed and fixed, preventing recurring leaks.
