Skylight Repair

Skylight Leak Repair in Kelowna & West Kelowna

A leaking skylight can cause water damage to ceilings, walls, and insulation. Most skylight leaks are not caused by the skylight unit itself but by failed flashing or sealant at the roof junction. Blue Jay Roofing diagnoses and repairs skylight leaks at the source.

Common causes of skylight leaks

  • Failed flashing — The metal flashing that connects the skylight to the roof deck is the most common leak point. Cracked sealant, rust, or improper original installation can allow water to enter around the skylight curb.
  • Cracked or aged sealant — Exterior sealant around the skylight frame degrades over time from UV exposure and temperature cycles. Okanagan freeze-thaw cycles accelerate sealant failure.
  • Condensation — In some cases, what appears to be a leak is actually condensation forming on the interior skylight surface. This happens when warm interior air meets a cold skylight surface. Improved attic ventilation may be the solution rather than a skylight repair.
  • Damaged glazing or frame — Impact damage from hail, falling branches, or severe weather can crack the skylight glazing or dent the frame. In these cases, the skylight unit itself may need replacement.

Our repair approach

We inspect both the interior and exterior of the skylight, including the attic space around the skylight shaft, to identify the exact source of the leak. For flashing leaks, we remove old sealant and flashing, inspect the surrounding roof deck for water damage, and install new flashing with proper sealant. If the skylight unit is damaged, we can replace it with a new energy-efficient model.

FAQ

Common questions

How do I know if my skylight leak is from the skylight or the roof?

Skylight leaks typically show water stains directly around or below the skylight opening. Roof leaks may appear further from the skylight. We trace the water path from the interior stain back to the source to determine the exact origin.

Can you repair a skylight without replacing it?

In most cases, yes. Flashing and sealant repairs resolve the majority of skylight leaks without replacing the unit. We only recommend replacement if the glazing is cracked, the frame is damaged, or the unit is an older single-pane model worth upgrading for energy efficiency.
