- Common causes of skylight leaks include improper installation, aging materials, poor maintenance, roof damage, and condensation.
Common Causes of Skylight Leaks
Skylights can bring natural light and ventilation into your home, but if they develop leaks, they can cause serious water damage. Here are some of the most common causes of skylight leaks:
| Causes | Description |
|---|---|
| Improper Installation | Skylights that are improperly installed can result in water infiltration. For instance, if the flashing around the skylight is not secured or fastened properly, water can seep in around the edges of the skylight and cause leaks. |
| Aging Materials | Over time, skylights can experience wear and tear, particularly when exposed to extreme weather conditions. The seals, gaskets, and glazing used in skylights can weaken with age and allow moisture to penetrate, resulting in leaks. |
| Poor Maintenance | Skylights require regular maintenance to ensure they remain in good condition. Failure to keep them clean and free from debris can lead to blockages that cause water to overflow and penetrate the skylight. |
Other factors that can contribute to skylight leaks include roof damage, condensation, and ventilation problems. By understanding these common causes, you can take proactive measures to prevent and address any leaks that may arise. In the following sections, we’ll delve deeper into each of these causes and provide tips for fixing and preventing skylight leaks.

Improper Installation and Flashing Issues
Improper installation or flashing issues are often the main culprits for skylight leaks. Even small installation mistakes can result in significant water infiltration.
Common installation errors that cause skylight leaks include using incorrect materials, failing to install flashing around the skylight, and not securing the skylight properly. These issues can lead to water leaks around the skylight area, causing damage to the surrounding roof structure and interior spaces.
Inadequate or damaged flashing is another major cause of skylight leaks. Flashing is designed to prevent water from seeping into your home through gaps and joints around the skylight. If flashing is damaged or improperly installed, water can penetrate these openings and cause leaks.
Diagnosing skylight leakage requires a thorough inspection of the skylight and the surrounding area. If you suspect installation or flashing issues are causing your skylight to leak, it’s best to seek professional help to diagnose and fix the problem.
Improper Installation and Flashing Issues Solutions
To solve installation and flashing issues, it’s recommended to hire licensed and experienced roofers or skylight professionals. They can inspect and identify the root cause of the problem and develop a solution that best fits your skylight type and roof structure.
Some potential solutions include resealing flashing, installing new flashing, or replacing the skylight entirely. It’s important to address these issues promptly to prevent further water damage and ensure the long-term functionality of your skylight.
Aging Materials and Deterioration
Skylights, like all structures, are subject to wear and tear over time. Exposure to the elements, temperature fluctuations, and other factors can cause materials to deteriorate, compromising the integrity of your skylight. When seals, gaskets, and glazing start to break down, they can develop cracks and gaps that allow water to seep in around the skylight. Additionally, UV rays can cause plastics to become brittle and shatter, leaving your skylight vulnerable to leaks.
The best way to prevent leaks related to aging materials and deterioration is to perform regular inspections and maintenance. Check for cracks or gaps in the skylight and surrounding flashing, and replace any worn-out or damaged materials promptly. By replacing seals and gaskets as needed, you can prolong the lifespan of your skylight and avoid costly water damage.
Roof Damage and Poor Maintenance
Roof damage and poor maintenance are common causes of skylight leaks. When your roof is damaged, water can seep into the skylight area, causing leaks. Missing shingles or damaged flashing are some of the most common culprits.
Regular maintenance can help prevent skylight leaks. By inspecting your roof and skylight regularly, you can detect any issues before they become major problems. Make sure to clear any debris from your roof and gutters, as clogs can lead to water buildup and damage.
If you notice any signs of damage, such as cracked shingles or rusted flashing, it’s important to address the issue promptly. Small repairs can prevent larger, more costly repairs down the line.

Condensation and Ventilation Problems
While poor installation and aging materials are often the primary culprits for skylight leaks, condensation and ventilation problems can also cause water infiltration. In fact, up to 80% of all skylight leaks are due to condensation issues.
Inadequate ventilation and excessive condensation can lead to moisture buildup around the skylight area, resulting in water leaks. This moisture can form on the inside of the skylight, even if the exterior is dry.
How can you prevent condensation and ventilation problems?
- Make sure your skylight is properly ventilated to reduce the likelihood of moisture buildup.
- Monitor humidity levels in your home to ensure they are at an appropriate level. High humidity can exacerbate condensation issues, while low humidity can cause cracking and drying of skylight seals and gaskets.
- Install ventilation fans in areas where moisture is common, such as bathrooms and kitchens.
If you suspect that condensation is causing your skylight leaks, it is important to address the issue promptly to prevent further damage.
How to Fix a Leaking Skylight
If you have identified a leak in your skylight, don’t panic. There are several ways to fix a leaking skylight, depending on the severity of the issue. Here are some solutions to consider:
1. Check the seals and flashing
One of the most common causes of skylight leaks is faulty seals or flashing. To fix the issue, inspect the seals and flashing for any cracks or damage. If you see any issues, remove the damaged material and replace it with new sealant or flashing tape. Make sure to use the correct type of sealant or flashing tape recommended for your skylight.
2. Apply a skylight sealant
If the skylight is in good condition but still leaks, you can apply a skylight sealant to the edges of the skylight frame. This will help to prevent water from seeping into the skylight. Be sure to follow the manufacturer’s instructions when applying the sealant.
3. Clear debris from the skylight
If the skylight is clogged with debris, it can prevent proper drainage and cause leaks. To fix the issue, remove any leaves, branches, or other debris from the skylight. You can do this by hand or with a soft-bristled brush. Make sure to clear the entire skylight and the surrounding area.
4. Address ventilation issues
Inadequate ventilation can cause excessive condensation, which can lead to skylight leaks. Make sure your skylight is properly ventilated by installing vents or fans as needed. This will prevent moisture buildup and minimize the risk of leaks.
5. Consider professional repair services
If DIY efforts are not successful, consider hiring a professional skylight repair service. A skilled technician can identify the root cause of the leak and implement the appropriate repair solution. This option may be more expensive than DIY repairs, but it can save you time and prevent further damage to your home.
No matter which method you choose, it is important to address skylight leaks promptly to prevent further damage to your home. Take action as soon as you notice any signs of leakage, such as water spots or discoloration on your ceiling.
