Skylight Leaking? Causes and Fixes That Actually Last
Roof leaks rarely start as emergencies — they start as small, fixable problems. In this guide, Roof Leak Repair Masters, your local licensed expert in Campbell, CA, explains what skylight leaking? causes and fixes that actually last means for your home and when to call a certified expert.
Condensation vs. a Real Leak
Not every drip under a skylight is a roof leak. Condensation forms on cold skylight glass when warm, moist indoor air hits it — common in bathrooms and kitchens in winter. If the moisture is on the glass or frame interior and there is no rain, improve ventilation before assuming the roof failed.
Failed Skylight Flashing
Genuine skylight leaks usually come from the flashing kit, not the glass. Step flashing along the sides and the head flashing above must weave into the shingles correctly; older skylights often have site-built flashing that was never right. Cracked or perished rubber gaskets on the unit itself are the other common culprit.
Weep Holes and Clogged Channels
Skylights have weep channels that drain incidental water. When debris clogs them, water backs up into the frame and drips inside. Clearing the channels and checking the gaskets is a quick diagnostic that solves a surprising number of 'leaks'.
Repair or Replace the Skylight?
If the flashing is the problem and the unit is sound, re-flashing with a manufacturer kit solves it. But if the skylight is 15+ years old, fogged between panes, or the frame is warped, replacing the unit during the repair is usually smarter — the labor overlaps, and you get a modern energy-efficient unit with a warranty.
A Local Note for Campbell Homeowners
Campbell's Mediterranean climate means months of dry heat followed by winter atmospheric rivers. Shingles bake and shrink all summer, then the first big storm of the season exposes every gap at once. Campbell mixes 1950s–70s ranch homes with newer infill and downtown lofts. Many original roofs have been replaced once; the second-generation roofs now hitting 20–25 years are entering peak leak territory. Campbell's mix of mid-century ranches and newer infill means we work on everything from original 1960s shingles to modern architectural systems. Our diagnosis always starts with the roof you actually have — not a one-size-fits-all script.
