A skylight is chosen for the natural light it easily brings into a home, turning it into a warm and inviting atmosphere for you to live in. However, due to heavy rain, snowfall, or hailstorms, skylights become a source of frustration and potential damage. Having a proper understanding of what makes them leak and how to fix it is necessary for homeowners, helping them identify issues and address them effectively. That’s why we’ve created this blog post so that homeowners like you can learn all there is to know about roof skylight leaks.
Signs of a Leaking Skylight
Here are some of the early signs of a skylight leak:
Water Stains on Ceilings or Walls
If you notice water stains on your ceiling or walls near the skylight, it’s a common sign that you’re dealing with a skylight leak. These stains often appear yellowish or brown, suggesting that water has been leaking through over time. If you notice these types of stains, do not neglect them since they are evidence that larger issues may happen with your skylight in the near future.
Moisture Buildup and Mold Growth
Moisture buildup is another common sign that the integrity of your skylight is compromised. Over time, this moisture can lead to mold growth and affect the quality of your home’s indoor air. To prevent any moisture buildup, you need to inspect your skylight for cracks in the glass or gaps in the seals, as these are common entry points for water.
Dripping Water and Warped Frames
After heavy rain, if you notice any water dripping down from your skylight, it is a clear indication that there is a skylight leak. Warped or discolored frames around the skylight often point to prolonged exposure to moisture, too. If you notice peeling paint or drywall that’s sagging near the skylight, it’s time to investigate further.
Common Cause of Skylight Leaks
Like any other roofing issue, there are several factors behind a skylight leak. However, issues like improper installation, worn-out seals, or roof damage around the skylight are considered to be the common causes of this problem. Poorly installed units often have gaps that allow water to seep through. Over time, seals also deteriorate, losing their ability to keep moisture out and damage to the surrounding roof can create pathways for leaks.
Improper Installation
Misaligned or loosely installed roofing materials allow rain to enter the roof and cause leaks during heavy storms. This is why it’s so important to have the skylight installed by a professional from the start.
Worn-Out Seals and Materials
A skylight relies heavily on seals to maintain its watertight integrity. However, after a certain period of time, frequent exposure to harsh weather conditions can cause the skylight to shrink or suffer from cracks around its seals. When this happens, even little rain showers can lead to leaks. This is why homeowners are always advised to perform regular inspections in order to identify aging materials before they fail and allow homeowners to address potential problems early.
Damage to Surrounding Roofing Materials
A roof skylight leak often stems from damage to shingles or tiles near the skylight. Strong winds, falling debris, or general wear and tear weaken these materials, creating openings for water. Ensuring the surrounding roof is in good condition reduces the risk of leaks.
Moisture Buildup
Moisture usually forms when the temperature difference between indoor and outdoor air causes moisture to collect on the skylight’s surface. Although this is not a traditional leak, it can still result in water pooling and eventual damage. Proper ventilation reduces the likelihood of moisture buildup. Using high-quality skylights with thermal insulation also reduces this issue.
How to Fix a Skylight Leak
To fix leaky skylights, the most important thing to keep in mind is finding the source of the leak. Here are some of the ways to identify the need for, and handle, a skylight repair.
Identify the Source of the Leak
Inspect the Skylight: Examine both the interior and exterior of the skylight for signs of damage, such as cracked seals, damaged flashing, or improper installation.
Check for Clogged Weep Holes: Weep holes allow wind frames to drain water and moisture away from the window. Ensure that the skylight’s weep holes are clear to allow water drainage.
Cracked or Broken Seals: If your skylight is causing a leak, you can use any silicone-based sealant around the edges of the skylight to prevent water from seeping in. This is often a straightforward fix for minor leaks.
Improper Installation: If misalignment is detected, you may need to readjust the skylight or consult a professional for proper installation.
Damaged Flashing: Repair or replace any damaged flashing around the skylight to create a watertight seal.
Aging or Weathering: For older skylights, consider applying a fresh coat of sealant or replacing the unit if significant wear is evident.
A Step-by-Step Repair Process
Here’s a complete step-by-step guide for you to understand the skylight repair process if you find yourself dealing with leaks.
1. Inspect the Skylight
To fix the leak, inspect the skylight and surrounding roof for visible issues such as cracked glass, damaged flashing, or gaps in the sealant. Use a garden hose to simulate rain and pinpoint the exact location of the leak.
2. Gather Tools and Materials
Prepare items like a ladder, safety harness, roofing sealant, silicone caulk, a caulking gun, utility knife, and replacement flashing or glass if needed.
3. Clean and Prepare the Area
Clear away dirt, debris, and old sealant from the skylight frame and surrounding roof area. Use soapy water and a rag to clean thoroughly, ensuring the surface is dry and ready for repairs.
4. Reseal or Replace Components
To complete your skylight repair, you will need to seal the frames around the skylight with the help of a sealant to close all the gaps. Now you can replace damaged flashing with new flashing material and secure it tightly with the use of nails or screws.
5. Final Exception
Before finishing up, you need to inspect the skylight for the last time in order to determine if your project was successful or not. It will also give you peace of mind regarding the safety concerns related to your skylight repair.
The Cost of Skylight Repair
The cost of repairing a leaking skylight varies depending on how extensive the leak is. Minor repairs do not cost as much money, but more significant issues and structural damage to the skylight might require a larger investment. However, if you choose high-quality roofing materials and experienced professionals for the original installation, while it may cost more initially, you’ll end up with long-term durability while reducing the need for frequent skylight repairs in the future.
Why Professional Help Matters
Attempting to fix a leaky skylight without the proper expertise can lead to further issues. This is why homeowners must consult with a trusted roofing company for better offers, guidance, and transparency regarding their project. Remember, quality workmanship often saves you money in the long run by preventing recurring issues.
