Skylights are a fantastic way to brighten up your home, bringing natural light and fresh air into spaces that might otherwise feel dark and enclosed. Velux, a leading brand in skylights, is known for its quality and durability. However, like any home feature, skylights can sometimes experience problems. Knowing how to troubleshoot common Velux skylight issues can save you time, money, and the headache of calling a professional for minor fixes.
My Skylight's Leaking! What Do I Do?
A leaky skylight is arguably the most common and concerning problem. Don't panic! While it could be a sign of a major issue, often it's something relatively simple to address. Here's a step-by-step approach to diagnosing and (hopefully) fixing the leak:
Identify the Source: This is crucial. Is the leak coming from around the edges of the skylight, through the glass itself, or somewhere else? Carefully examine the area while it's raining, or use a garden hose to simulate rain. Have someone inside observe the water entry point.
Check the Flashing: The flashing is the metal that surrounds the skylight and seals it to the roof. It's the primary defense against water intrusion. Look for:
- Damage: Are there any dents, cracks, or rust spots?
- Loose Flashing: Can you easily wiggle the flashing? It should be securely attached to both the skylight and the roof.
- Missing Caulk: The caulk that seals the flashing can deteriorate over time. Look for cracks or gaps.
- Incorrect Installation: If the skylight was recently installed, poorly installed flashing is a prime suspect. Unfortunately, this might require professional assistance.
Inspect the Skylight Frame: Check the frame itself for cracks or damage. Pay particular attention to the corners, as these are common weak points.
Examine the Glass: While rare, cracks in the glass itself can cause leaks. Even a tiny crack can allow water to seep through.
Possible Solutions:
- Recaulking: If the caulk is cracked or missing, carefully remove the old caulk with a utility knife and apply a new bead of high-quality, exterior-grade caulk specifically designed for roofing applications. Make sure the area is clean and dry before applying the caulk.
- Flashing Repair: Minor dents can sometimes be hammered back into shape. If the flashing is loose, try tightening any screws that hold it in place. If the flashing is severely damaged, it will likely need to be replaced. This is often best left to a professional.
- Glass Replacement: If the glass is cracked, it will need to be replaced. This is not a DIY project unless you have significant experience with glasswork.
- Roofing Issues: Sometimes, the leak isn't the skylight's fault at all! Water can travel down the roof and appear to be coming from the skylight. Check the surrounding roofing materials for damaged shingles, missing granules, or other signs of wear and tear.
Important Note: Working on a roof can be dangerous. Always take proper safety precautions, including wearing appropriate footwear, using a safety harness, and having someone spot you. If you are not comfortable working on a roof, it's best to call a professional.
My Skylight Won't Open (or Close!)
A skylight that's stuck open or closed can be frustrating. Here's how to troubleshoot this problem:
Check the Operator: Is it manual or electric?
- Manual Skylights:
- Crank Mechanism: Make sure the crank handle is properly engaged. If it's slipping, the gears inside the mechanism might be worn or damaged.
- Binding: The skylight may be binding against the frame. Try gently pushing or pulling on the skylight while turning the crank.
- Obstructions: Check for any obstructions that might be preventing the skylight from opening or closing, such as debris or ice.
- Electric Skylights:
- Power Supply: Make sure the skylight is receiving power. Check the circuit breaker.
- Remote Control: Check the batteries in the remote control. Try reprogramming the remote.
- Motor: The motor might be faulty. Listen for any unusual noises when you try to operate the skylight.
- Limit Switches: Electric skylights have limit switches that stop the motor when the skylight reaches its fully open or fully closed position. These switches can sometimes malfunction.
- Manual Skylights:
Possible Solutions:
- Lubrication: Lubricate the moving parts of the operating mechanism with a silicone-based lubricant. Avoid using oil-based lubricants, as they can attract dirt and grime.
- Cleaning: Clean the skylight frame and the surrounding area to remove any debris that might be causing binding.
- Remote Control Reset: Refer to your Velux owner's manual for instructions on how to reset the remote control.
- Motor Replacement: If the motor is faulty, it will need to be replaced. This is often best left to a professional.
- Professional Inspection: If you've tried these steps and the skylight still won't open or close, it's time to call a qualified skylight repair technician.
Condensation Issues: Why is My Skylight Foggy?
Condensation on skylights is a common issue, especially during colder months. It occurs when warm, moist air inside your home comes into contact with the cold surface of the skylight glass. While some condensation is normal, excessive condensation can lead to mold growth and other problems.
Identify the Cause:
- High Humidity: Is your home particularly humid? Common culprits include long showers, cooking, and indoor plants.
- Poor Ventilation: Is your home properly ventilated? Make sure your exhaust fans are working properly and that you're opening windows regularly to allow fresh air to circulate.
- Skylight Construction: Older, single-pane skylights are more prone to condensation than newer, double-pane or triple-pane skylights.
- Seal Failure: If you have a double-pane or triple-pane skylight, the seal between the panes of glass may have failed, allowing moisture to enter the space between the panes. This will appear as fogging or condensation inside the glass.
Possible Solutions:
- Reduce Humidity:
- Use exhaust fans in bathrooms and kitchens.
- Vent your clothes dryer to the outside.
- Avoid overwatering indoor plants.
- Consider using a dehumidifier.
- Improve Ventilation:
- Open windows regularly, even during colder months.
- Make sure your attic is properly ventilated.
- Seal Failure: If the condensation is between the panes of glass, the skylight will need to be replaced. There is no way to repair a broken seal.
- Insulation: Ensure proper insulation around the skylight frame to minimize temperature differences.
My Skylight is Drafty! Brrr!
A drafty skylight can make your home uncomfortable and increase your energy bills. Here's how to find and fix the draft:
- Feel for Air Leaks: On a cold day, carefully run your hand around the edges of the skylight to feel for any drafts.
- Check the Seals: Inspect the seals around the skylight frame and the flashing for cracks or gaps.
- Look for Gaps: Use a flashlight to look for any gaps between the skylight and the roof.
Possible Solutions:
- Weatherstripping: Apply weatherstripping around the skylight frame to seal any gaps.
- Caulking: Recaulk any cracks or gaps in the seals around the skylight.
- Insulation: Add insulation around the skylight frame to reduce heat loss.
- Professional Inspection: If you can't find the source of the draft, it's best to call a professional to inspect the skylight and the surrounding roof.
My Skylight is Discolored or Cloudy
Over time, skylight glass can become discolored or cloudy due to exposure to the sun and weather. This can reduce the amount of light that enters your home.
- Cleaning: Try cleaning the skylight with a mild soap and water solution. Use a soft cloth or sponge to avoid scratching the glass.
- Professional Cleaning: If the discoloration is severe, you may need to hire a professional skylight cleaning service.
- Replacement: If cleaning doesn't improve the discoloration, the skylight may need to be replaced.

- Reprogram the Remote: Refer to your Velux owner's manual for instructions on how to reprogram the remote.
- Check the Receiver: Make sure the receiver on the skylight is receiving power.
