Assessing the Damage
Before you begin any repairs, it’s crucial to identify the source of the leak.
Inspecting the Flashing
The flashing around your skylight is the primary barrier against water intrusion. Check for:
Cracks or gaps in the flashing material.
Loose or missing nails or screws.
Signs of rust or corrosion.
Checking the Sealant
The sealant around the skylight frame should be intact and free of cracks or gaps.
Look for signs of deterioration, such as discoloration or shrinkage.
Examining the Skylight Pane
Inspect the skylight pane itself for:
Cracks or holes.
Loose or damaged glazing.
Gathering Your Tools and Materials
Once you’ve identified the problem, gather the necessary tools and materials for the repair:
Safety gear: Gloves, goggles, and a ladder.
Cleaning supplies: A bucket, sponge, and cleaning solution.
Flashing repair materials: New flashing material (aluminum, copper, or rubber), roofing nails or screws, and sealant.
Sealant: Roofing cement or silicone caulk.
Caulk removal tool: A putty knife or caulk remover.
Utility knife: For cutting flashing material.
Ladder: A sturdy ladder that reaches the skylight safely.

If the flashing is damaged, you’ll need to replace it.
1. Carefully remove the old flashing using a utility knife and pry bar.
2. Clean the surface around the skylight thoroughly.
3. Cut the new flashing material to size and shape.
4. Apply a bead of sealant along the edges of the flashing.

Repairing the Sealant
If the sealant around the skylight frame is damaged, you’ll need to replace it.
1. Use a caulk removal tool to carefully remove the old sealant.
2. Clean the surface around the skylight thoroughly.
3. Apply a bead of new sealant around the frame, pressing it firmly into place.
4. Allow the sealant to cure completely according to the manufacturer’s instructions.

1. Carefully remove the old pane, taking care not to damage the frame.
2. Install the new pane, following the manufacturer’s instructions.
3. Apply a bead of sealant around the edges of the pane.

Once you’ve repaired your leaky skylight, take steps to prevent future leaks:
