Skylight Repair in Astoria & Queens, NY

This is one of the most common points of confusion we run into, and it’s worth understanding before assuming the worst. Condensation forms on the interior surface of the glass, typically in cold weather or in rooms with higher humidity, like a bathroom or kitchen. It shows up as fine droplets rather than staining, and it often improves with better ventilation or a dehumidifier rather than a roofing repair. An actual leak, by contrast, tends to show up as staining that extends beyond the frame itself, appears during or shortly after rain regardless of the temperature difference, and gets worse over time rather than fluctuating with humidity. If you’re not sure which you’re dealing with, that’s exactly what an inspection is for, and it can save you the cost of a repair you didn’t actually need.

Common Skylight Repairs We Perform

Flashing replacement and resealing, correcting the root cause behind most skylight leaks

Reglazing or seal replacement for fogged or failed double-pane units

Curb repair or rebuild, addressing wood rot or deterioration underneath the unit

Gasket and weatherstripping replacement on operable, vented skylights

Full unit replacement, when a skylight’s glazing or frame is too far gone for a repair to make sense

Types of Skylights We Repair

Not all skylights are built or installed the same way, and repair approach depends on the type:

Fixed skylights, which don’t open, are the most common and typically fail through flashing or glazing seal issues rather than mechanical problems

Vented or operable skylights, which open manually or electronically, add gaskets, weatherstripping, and sometimes motorized components to the list of things that can wear out

Curb-mounted skylights, sitting on a raised wood or metal curb built into the roof, the most common style on flat-roof additions, and where curb rot is most likely to develop

Deck-mounted skylights, installed with a lower profile directly against the roof deck, common on newer construction

Tubular skylights, small reflective tubes bringing daylight into interior rooms like bathrooms without a full window, these fail less often through leaks and more through seal degradation at the roof-level dome

Knowing which type you have changes both the likely failure point and the repair method, which is part of what we assess during the inspection.

Skylight Repair Cost Factors

Skylight repair cost depends on what’s actually wrong. A flashing reseal is generally the most affordable fix, while curb rebuilding or full reglazing costs more due to the materials and labor involved. Roof accessibility, skylight size, and whether it’s a fixed or operable unit also factor in. As with any repair, we provide a written estimate after inspection so you know the cost before committing to anything.

Skylights on Flat-Roof Additions

A lot of Queens row houses have flat-roofed rear extensions, a kitchen or dining room addition with a skylight bringing light into what would otherwise be a dark interior room. These installations come with a specific challenge: tying a skylight curb properly into a flat membrane roof is a different job than flashing a skylight into pitched shingles, and it’s an area where we frequently find shortcuts taken during the original construction, especially on additions built without a licensed roofer involved. Ponding water near a poorly integrated skylight curb accelerates leaks in exactly this kind of setup, which is why we pay particular attention to slope and drainage around the skylight itself, not just the flashing seal. If your rear extension skylight leaks every time it rains hard but seems fine otherwise, drainage around the curb, rather than the skylight itself, is often the actual culprit.

Repair or Replace? Skylight Lifespan

Most quality skylight units last somewhere between 10 and 20 years, though the glazing seal often fails well before the frame or structure does, which is why fogging is such a common complaint on otherwise structurally sound units. Repair generally makes sense for isolated flashing failures, a single failed seal, or gasket wear. Replacement starts to make more sense when a skylight has needed repeated reflashing without lasting results, when the curb has significant rot, or when multiple panes across an aging unit are showing seal failure at once. We’ll always tell you honestly which category yours falls into rather than defaulting to the more expensive option. A well-diagnosed repair on a fundamentally sound skylight can add years of useful life for a fraction of replacement cost.

Our Skylight Repair Process

Inspection, both from inside the room and at roof level, to properly diagnose whether you’re dealing with a leak, condensation, or seal failure

Diagnosis, identifying the actual root cause rather than just resealing the visible symptom

Written estimate, outlining the repair method and cost before any work begins

Repair, using flashing, sealant, or replacement components matched to your skylight type and roof system

Post-repair check, including a recommendation to monitor after the next rain to confirm the fix is holding

Why Choose Us for Skylight Repair

Experience with skylights across both pitched and flat-roof installations

Honest diagnosis, including telling you when it’s condensation rather than a leak

Flashing-first repair approach, addressing root causes instead of surface symptoms

Workmanship warranty on completed repairs

Familiar with the specific challenges of skylights on Queens row house rear additions

A leaking or fogged skylight is rarely a reason to replace the whole unit, and we’d rather fix the actual problem for a fraction of the cost than sell you a replacement you don’t need. If replacement genuinely is the right call, we’ll explain exactly why before recommending it.
