What Should You Do With Skylight Leaking in Winter?

February 5, 2024

3 minutes read

Skylight leaking in winter can be challenging, but you can do something about it.

As winter settles, you may encounter an unpleasant surprise: a leaking skylight. 

While skylights are wonderful for bringing natural light into your home, they can sometimes pose challenges during colder months. 

Leaks not only compromise the comfort and aesthetics of your property but also raise concerns about potential damage. However, fret not! 

In this guide, we’ll delve into the causes of skylight leaks and provide practical steps to address them effectively.

Understanding the Causes:

Skylight leaking in winter can stem from various factors, including:

  1. Condensation: During winter, temperature differentials between the warm interior and the cold exterior can lead to condensation buildup on skylights. This moisture can seep into cracks or gaps, causing leaks.
  2. Ice Dams: In regions like Woodbury, where snow accumulation is common, ice dams can form on roofs. When ice melts and refreezes near skylights, it can create gaps that allow water to penetrate.
  3. Aging Seals or Flashing: Over time, seals and flashing around skylights can degrade due to exposure to harsh weather conditions. Cracked or damaged seals provide an entry point for water.
  4. Poor Installation: Incorrectly installed skylights may not have adequate flashing or sealing. This makes them susceptible to leaks, particularly during winter storms.

Steps to Address Skylight Leaking in Winter:

If you notice a skylight leak in your home, here’s what you can do:

Step 1: Inspect for Damage

Begin by carefully examining the skylight and its surrounding area for any signs of damage, such as cracks, gaps, or missing flashing. Use caution when accessing the roof and consider enlisting the help of a professional if needed.

Step 2: Clear Snow and Ice

Safely remove any snow or ice buildup from the roof, particularly around the skylight. Use a roof rake or a broom with a long handle to clear away excess snow. Take care not to damage the roof or skylight in the process.

Step 3: Seal Cracks and Gaps

Use a high-quality exterior caulk or sealant to fill in any cracks or gaps around the skylight frame. Ensure that the sealant is also compatible with the skylight material and provides adequate waterproofing.

Step 4: Improve Insulation

Enhancing insulation around the skylight can help mitigate condensation and prevent heat loss, reducing the likelihood of leaks. Consider adding insulation foam or weather-stripping around the frame as needed.

Step 5: Upgrade Flashing

If the skylight flashing appears worn or damaged, consider replacing it with new flashing that provides a better seal against moisture intrusion. Properly installed flashing is crucial for preventing leaks, especially in winter conditions.

Step 6: Monitor Regularly

After addressing any immediate issues, continue to monitor the skylight for signs of leaks throughout the winter season. Prompt skylight leak repair will be crucial to prevent further damage to your home.

Seeking Professional Assistance:

While DIY measures can often resolve minor skylight leaks, complex issues or extensive damage may require professional intervention. 

If you’re unsure about how to proceed or encounter persistent leaks despite your efforts, don’t hesitate to consult with a qualified roofing contractor or skylight specialist.

These professionals can conduct a thorough inspection, identify underlying issues, and recommend appropriate repairs or replacements.
