Skylights are a wonderful addition to any home, offering natural light and beautiful views of the outdoors. However, like any other part of your roof, skylights can develop issues over time, one of the most common being leaks. If your skylight is leaking, it’s important to act quickly to prevent further damage to your home’s interior. In this blog, we’ll walk you through the steps you need to take when your skylight starts leaking, and help you understand the causes, solutions, and when it might be time for a replacement.
Why Does My Skylight Leak When It Rains?
A skylight leaking during rainfall is a common problem, and it usually points to issues with the skylight’s installation or its sealant. Skylights are designed to keep water out, but if the sealant around the edges deteriorates over time, water can seep in. Other common causes include clogged gutters or debris blocking the drainage system of the skylight, which forces rainwater to pool and seep through.
It’s also possible that your skylight has cracks in the glass or surrounding frame, which allows water to penetrate. A poorly installed or old skylight may also suffer from structural issues that lead to leaks during heavy rain.
How to Stop a Skylight from Leaking?
To stop a skylight from leaking, the first step is to identify the source of the leak. Here are some methods to help you address the problem:
- Inspect the Sealant: Over time, the sealant around your skylight can wear down. Check for cracks or gaps, and reapply a high-quality silicone or rubber sealant if necessary. Ensure the sealant is applied evenly to prevent water from seeping in.
- Clean the Drainage System: If your skylight has a drainage system, make sure it is not clogged with debris, leaves, or dirt. Clean the channels and ensure that rainwater can flow freely.
- Check for Cracks or Damage: Inspect the skylight glass and frame for any visible cracks or damage. If you find any, these should be repaired or replaced as soon as possible.
- Install a Skylight Flashing: Flashing is designed to protect skylights from water intrusion. If your skylight doesn’t have flashing or it’s worn out, consider installing a new flashing system to help direct water away from the skylight.
How Do I Make My Skylight Not Leak?
Preventing skylight leaks involves regular maintenance and taking steps to ensure proper installation. Here’s how to keep your skylight in top condition:
- Routine Inspections: Regularly inspect the skylight for signs of wear, especially after storms or heavy rain. Look for cracks in the glass, gaps in the sealant, and signs of water damage around the skylight.
- Maintain the Roof: A well-maintained roof plays a significant role in preventing skylight leaks. Ensure your roof is free of damage, and that gutters and downspouts are clear of debris to avoid water backup.
- Upgrade the Sealant: If the sealant around your skylight is old or cracked, replace it with a high-quality, weather-resistant option to ensure a watertight seal.
- Consider Professional Help: If you’re unsure of how to maintain or repair your skylight, a roofing professional can inspect it and offer the right solution.
What Is the Most Common Cause of Skylight Leaks?
The most common cause of skylight leaks is a deteriorated or faulty sealant. As time passes, the materials used around your skylight can degrade due to weather exposure, especially in extreme temperatures. If not properly maintained, gaps and cracks can form, allowing water to seep in. Other causes include:
- Improper Installation: If the skylight was poorly installed or not sealed correctly, leaks can occur.
- Roof Damage: If the roof around the skylight is damaged or aging, it can also lead to leaks.
- Condensation Issues: Poor ventilation around the skylight can cause condensation, which may lead to water dripping down and pooling.
Immediate Actions to Take When Your Skylight Starts Leaking
If you notice water dripping from your skylight, it’s important to take immediate action to minimize the damage. Here’s what you should do:
- Protect Your Interior: Place a bucket or container under the leak to catch any water and prevent it from damaging your floors or furniture.
- Inspect for Visible Damage: Carefully inspect the skylight for any cracks or visible gaps. If you notice any, you may be able to temporarily seal the gap with waterproof tape or plastic sheeting until you can get professional help.
- Check the Surrounding Roof Area: If possible, check the roof area around the skylight to see if there are any obvious issues with the roof that may be contributing to the leak.
- Call a Roofing Professional: A qualified roofing contractor can quickly identify the source of the leak and recommend the best course of action.
When to Replace Your Skylight Instead of Repairing It
While many skylight leaks can be repaired, there are times when a replacement is the more cost-effective and long-term solution. Consider replacing your skylight if:
- The Skylight Is Old or Damaged: If your skylight is more than 20 years old or shows significant damage that can’t be effectively repaired, replacing it may be the best option.
- Frequent Leaks: If you’ve had to repair your skylight multiple times and it continues to leak, it may be time for a new one.
- Poor Energy Efficiency: Older skylights are often less energy-efficient. If your skylight is causing your home’s energy bills to rise, it might be time to invest in a newer, more energy-efficient model.
Conclusion
A leaking skylight is a serious issue that can lead to extensive water damage if not addressed quickly. By understanding the causes of skylight leaks, taking immediate action to mitigate damage, and performing regular maintenance, you can extend the life of your skylight and keep your home safe and dry.
