How To Fix a Skylight Leak
A leaky skylight can be a real headache, both literally and figuratively. Not only does it allow water to damage your home’s interior, but it can also create a breeding ground for mold and mildew. Fortunately, fixing a skylight leak is often a DIY project that can be tackled with a few simple tools and some patience.
Identifying the Source of the Leak
Before you start repairing your skylight, it’s crucial to pinpoint the exact location of the leak. This can sometimes be tricky, as water can travel along rafters and other structural elements before dripping down.
Signs of a Skylight Leak
- Water stains on the ceiling or walls below the skylight
- Peeling paint or wallpaper
- Mold or mildew growth
- Dripping water from the skylight frame
To help locate the leak, try these tips:
- Check the skylight flashing around the perimeter of the skylight. Look for gaps, cracks, or missing pieces.
- Inspect the skylight seals. These seals prevent water from seeping in around the edges of the skylight.
- Examine the skylight itself for cracks or damage.
Tools and Materials You’ll Need
Once you’ve identified the source of the leak, you can gather the necessary tools and materials to make the repair.
- Ladder
- Safety glasses
- Gloves
- Caulk gun
- Roofing cement
- Flashing tape
- Utility knife
- Putty knife
- Clean rags
Repairing the Leak
The specific repair steps will vary depending on the type of leak and the age of your skylight. However, here are some general guidelines:
Repairing Damaged Flashing
If the flashing around your skylight is damaged, you’ll need to replace it.
- Carefully remove the old flashing using a utility knife.
- Clean the area thoroughly to remove any debris or loose sealant.
- Apply a bead of roofing cement to the surface of the roof where the flashing will be installed.
- Place the new flashing over the roofing cement, ensuring it overlaps the skylight edges by at least 2 inches.
- Secure the flashing in place with roofing nails or screws.
Sealing Gaps and Cracks
If you have small gaps or cracks in the skylight frame or seals, you can use caulk or sealant to repair them.
- Clean the area around the gap or crack thoroughly.
- Apply a bead of caulk or sealant to the gap.
- Smooth the caulk with your finger or a putty knife.
- Allow the caulk to dry completely before testing the repair.
Replacing Damaged Skylight Seals
Skylight seals can deteriorate over time, allowing water to seep in. If your seals are damaged, you’ll need to replace them.
- Remove the old seals carefully.
- Clean the area where the new seals will be installed.
- Apply a bead of roofing cement or sealant to the skylight frame.
- Press the new seals into place, ensuring they are securely adhered to the frame.
Preventing Future Leaks
Once you’ve repaired your skylight leak, take steps to prevent it from happening again.
- Inspect your skylight regularly for signs of damage, such as cracks, loose flashing, or worn seals.
- Clean your skylight at least twice a year to remove debris and prevent buildup.
- Consider installing a skylight cover to protect it from the elements.
- If you notice any signs of leaks, address them promptly to avoid further damage.
By following these tips, you can effectively fix a skylight leak and keep your home dry and comfortable.
