Vancouver’s rainy climate can take a toll on skylights, leading to leaks that can cause water damage, mold, and structural issues. However, a leaky skylight doesn’t always mean it needs to be replaced. Simple repairs can often extend its lifespan and keep your home dry and comfortable. In this guide, we’ll walk you through the most effective ways to fix a leaky skylight without replacing it.
Step 1: Identify the Source of the Leak
Before you can fix your skylight, you need to determine where the leak is coming from. Common sources include:
- Cracked or worn-out sealant around the skylight frame
- Damaged flashing that allows water to seep in
- Condensation buildup mistaken for a leak
- Loose or missing shingles around the skylight
- Gaps between the skylight and the roof due to improper installation
Use a flashlight to inspect the skylight from the inside and check for water stains, drips, or mold growth. If necessary, run a garden hose over the skylight while someone monitors the interior for leaks.
Step 2: Clean and Dry the Area
Once you’ve identified the leak, clean the affected area thoroughly. Use a cloth to wipe away any moisture, dirt, or debris. If mold is present, mix a solution of one part white vinegar with three parts water and gently scrub the area to prevent further growth.
Step 3: Reseal the Skylight
If the leak is caused by deteriorated sealant, reapplying a high-quality roofing sealant can often solve the problem.
- Remove old, cracked sealant using a putty knife.
- Apply a bead of 100% silicone or polyurethane sealant around the edges of the skylight.
- Smooth the sealant with a caulking tool or gloved finger to ensure an even, watertight application.
- Allow it to dry completely before testing for leaks.
Step 4: Repair or Replace Flashing
Flashing is the metal barrier that prevents water from seeping into your home around the skylight. If it’s loose or damaged:
- Carefully remove the old flashing using a pry bar.
- Install new flashing pieces, ensuring they overlap correctly to guide water away from the skylight.
- Secure the flashing with roofing nails and apply a layer of roofing cement for added protection.
- Check for gaps and seal them with waterproof caulk.
Step 5: Check and Fix Roof Shingles Around the Skylight
Loose or missing shingles can allow water to penetrate the area around the skylight. If you notice any issues:
- Replace missing shingles with new ones that match your roof.
- Secure shingles using roofing nails and apply roofing cement to prevent further lifting.
- Ensure that shingles properly overlap flashing for optimal water drainage.
Step 6: Address Condensation Issues
Sometimes, what appears to be a skylight leak is condensation forming due to temperature differences inside and outside your home. To reduce condensation:
- Improve ventilation by running an exhaust fan in humid areas like bathrooms or kitchens.
- Use a dehumidifier to maintain balanced indoor humidity levels.
- Add weather stripping around the skylight to minimize drafts and temperature fluctuations.
Step 7: Perform a Water Test
Once you’ve completed the skylight repairs, it’s time to test your work. Use a garden hose to simulate rain, directing water over the skylight and surrounding area. Have someone inside check for signs of moisture. If no leaks appear, your repair was successful.
Step 8: Prevent Future Leaks
To keep your skylight in top condition, follow these maintenance tips:
- Inspect your skylight twice a year, especially before and after Vancouver’s rainy season.
- Clean debris and leaves from around the skylight to prevent water buildup.
- Check the sealant and flashing annually for wear and tear.
- Ensure clear gutters and downspouts prevent water from pooling near the skylight.
