Identifying Skylight Leaks: Causes, Detection, and Solutions

Skylights offer a beautiful way to invite natural light into our homes, but they can also have issues: leaks. Dealing with skylight leaks requires prompt attention and proper understanding. 

In this blog, we’ll delve into the nuances of spotting skylight leaks, explore their underlying causes, and discuss potential solutions. From water stains to worn sealants, let’s shed light on this pervasive issue and find the best ways to address it effectively.

How to Spot a Skylight Leak

Detecting a skylight leak early can save you from extensive damage to your home’s interior. Here are some key signs to look out for:

  • Water Stains: Look for any discoloration or watermarks on ceilings and walls surrounding the skylight. These stains indicate water infiltration and can worsen if left unaddressed.
  • Pooling Water: Check for water accumulation around the skylight, especially after rainfall. Pooling water suggests that the skylight’s sealing may be compromised, allowing water to seep through.
  • Damp or Moldy Areas: Mold thrives in areas where water accumulates. If you notice any dampness or mold growth near the skylight, it clearly indicates a leak.

The 3 Top Causes of Skylight Leaks

Addressing the underlying causes of skylight leaks is vital for preventing them from happening in the first place. By identifying the root issue, homeowners and professionals can implement solutions to prevent further water infiltration and safeguard the integrity of the home’s interior. Here are the three top culprits of skylight leaks:

  • Poor Installation: Improper installation can lead to leaks over time. If the flashing around the skylight isn’t correctly installed or sealed, water can infiltrate the surrounding areas during rain or snowfall.
  • Age and Wear: Like any other component of your home, skylights undergo wear and tear over time. Sealants degrade and materials deteriorate, compromising the skylight’s waterproofing capabilities.
  • Structural Issues: External factors such as severe weather conditions, roof settling, or building structural changes can impact the integrity of skylights. Storm damage, including rain or hail, can compromise the skylight’s seals or flashing. 

How to Fix a Leaking Skylight

Leaking skylights demand prompt action to prevent further damage and restore the integrity of your home. By implementing these measures, homeowners and professionals can effectively address skylight leaks and restore the comfort and safety of the home’s interior. Here are three effective solutions to address skylight leaks:

  • Re-sealing: One of the primary methods to tackle skylight leaks is by re-sealing the skylight frame. This involves inspecting the existing sealant, caulking around the skylight, and applying fresh sealant where necessary. By reinforcing the sealant, you can effectively block any potential entry points for water infiltration.
  • Repairing Flashing: Flashing refers to the metal strips installed around the edges of the skylight to provide additional waterproofing. Damaged or worn flashing is a common cause of skylight leaks. Replacing damaged or worn flashing with new, properly installed flashing can significantly improve the skylight’s waterproofing capabilities.
  • Adjusting Slope: Ensuring proper water drainage away from the skylight is crucial for preventing leaks. If the roof’s slope around the skylight needs to be increased or corrected, water may pool around the skylight. Adjusting the roof’s slope or adding additional drainage mechanisms can help redirect water away from the skylight, reducing the potential for leaks. 

Note: Consult with experienced professionals for complex repairs or installations to ensure the job is done correctly and effectively.

When Is Replacing a Skylight Necessary?

While repair efforts can often resolve skylight leaks, there are situations where replacing the skylight becomes the most viable solution. Here are some signs indicating that repair efforts may not suffice and considering a replacement is best:

  • Extensive Damage: If the skylight has sustained extensive damage beyond repair, such as severe cracks, warping, or structural issues, replacement may be necessary. Attempting to patch up severely damaged skylights may only provide temporary relief and could lead to further complications down the line.
  • Recurrent Leaks Despite Repairs: Despite your best efforts to repair the skylight, leaks may continue to persist or recur shortly after repairs. This indicates underlying issues that cannot be addressed through repairs alone. Therefore, replacing the skylight with a new, properly installed unit may offer a more permanent solution.
  • Outdated Skylight Models: Older skylight models may lack advanced features and technologies found in modern skylights, making them more prone to leaks and energy inefficiency. Replacing it with a newer model can provide numerous benefits.

Note: Consult a professional to assess if replacement is the best course of action for your situation. A qualified contractor can recommend suitable replacement options tailored to your needs and ensure proper installation for optimal performance and longevity.
