Fixing Leaking Skylights: A Comprehensive Guide to Repairs and Maintenance

Introduction to Skylight Leaks

Skylights are a beautiful addition to any home, providing natural light and enhancing the aesthetic appeal of a room. However, when they leak, they can cause significant water damage and stress. Leaks often occur due to improper installation, damaged flashing, or worn-out sealants. In this article, we will explore the causes of skylight leaks and provide a detailed guide on how to fix a leaking skylight, including resealing, skylight flashing repair, and other essential maintenance tips.

Causes of Skylight Leaks

Skylight leaks can be attributed to several factors:

• Improper Installation: If the skylight is not installed correctly, it can lead to gaps and openings that allow water to enter.
• Damaged Flashing: Flashing is crucial for directing water away from the skylight. Damaged or improperly installed flashing can cause leaks.
• Worn-Out Sealants: Over time, the sealants around the skylight can deteriorate, allowing water to seep in.
• Condensation Issues: Sometimes, what appears to be a leak might actually be condensation. Ensuring proper ventilation can help resolve this issue.

How to Fix a Leaking Skylight

Fixing a leaking skylight involves several steps:

Step 1: Identify the Source of the Leak

Examine the skylight from both inside and outside to locate the source of the leak. Look for signs of damage, wear, or improper installation.

Step 2: Clean the Surrounding Area

Remove any debris, dirt, or old sealant from the skylight frame and adjacent roof area. A clean surface ensures that new sealants adhere properly.

Step 3: Apply Sealant or Caulk

Use a clear silicone sealant to reseal the skylight frame where it meets the roof. Apply the sealant smoothly with a caulking gun and press it into gaps with a putty knife.

Step 4: Check and Repair Flashing

Inspect the flashing around the skylight. If it’s loose or damaged, secure or replace it. Apply roofing cement under lifted edges to ensure a watertight seal.

Step 5: Inspect for Other Issues

• Condensation: Check for obstructions near weep holes and ensure good ventilation.
• Rubber Gasket: If the rubber seal is damaged, consider replacing it.
• Cracks in Glass: Visible cracks may require replacing the skylight.

Skylight Repairs and Maintenance

Skylight Window Repair

If the skylight itself is damaged, such as cracked glass, it may need to be replaced. This is a more extensive repair that often requires professional assistance.

Skylight Flashing Repair

Flashing is critical for preventing leaks. Damaged flashing should be repaired or replaced promptly to maintain the skylight’s integrity.

Roof Skylight Repair

Ensure that the surrounding roof area is in good condition. Missing or damaged shingles can exacerbate leaks around the skylight.

DIY vs. Professional Repair

While minor leaks can often be fixed with DIY methods, more complex issues may require professional assistance. If you’re unsure about your DIY skills or the extent of the damage, it’s best to hire a professional roofer.

Conclusion

Fixing a leaking skylight is a manageable task if you understand the causes and follow the right steps. By identifying the source of the leak, resealing the skylight, and repairing flashing, you can prevent further water damage and maintain your skylight’s functionality. Remember, if the issue persists or seems too complex, consulting a professional is always the best option.
