Skylight Leak Detection and Repair Guide

Step-by-Step

1

Confirm the Source

Determine if water is actually coming from the skylight or just appearing there. Water often travels from other roof locations before becoming visible at skylights.

2

Inspect Interior Seals

Check the interior gaskets and seals around the skylight frame for cracks, gaps, or deterioration. Look for water stains or mold on the skylight shaft walls.

3

Examine Exterior Flashing

Inspect the metal flashing around the skylight for damage, lifting edges, or improper installation. Flashing should overlap properly with roofing materials to direct water away.

4

Check Condensation

Determine if the "leak" is actually condensation forming on the glass due to temperature differences. This is common in bathrooms or kitchens with inadequate ventilation.

5

Test with Water

On a dry day, perform a water test by having someone spray above and around the skylight while you observe from inside for leak points. Start low and work upward.

⚠️ Safety Warning

Skylight repairs often require specialized knowledge of both roofing and window installation techniques. Improper repairs can lead to more serious water damage. Additionally, skylights create fall hazards when working on the roof, requiring proper safety equipment and experience.
