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 Co, your local licensed expert in Sayreville, NJ, 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 Sayreville Homeowners
Sayreville gets the full Northeast treatment: nor'easters, freeze-thaw cycles, ice dams, and humid summers. Each season attacks roofs differently — ice dams back water under eaves in winter, while summer storms exploit every flashing gap. From Parlin's mid-century neighborhoods to newer developments near the Raritan, Sayreville's housing spans 70 years of construction. Older roofs with original flashing and newer roofs with rushed details both develop leaks. Sayreville's freeze-thaw winters punish roofs: ice dams, cracked boots, and flashing worked loose by thermal cycling. We repair the leak and address the winter dynamics behind it, so the fix survives January.
