Clean and inspect skylights

Difficulty: moderateTime: 45 mins

Why it matters

Skylight seals degrade over years of UV exposure and thermal cycling. A small leak around the flashing causes water damage in the ceiling and attic that homeowners often blame on the roof.

Stop forgetting to do this.

How to do it

  • 1

    Clean the glass with a squeegee and streak-free glass cleaner from the outside.

  • 2

    Inspect the flashing around the perimeter — look for gaps, rust, or lifted edges.

  • 3

    Check the interior frame for water stains or condensation between panes.

  • 4

    Apply silicone caulk to any gaps in the flashing (a temporary fix — a roofing pro should address flashing issues).
