Generic Skylight Installation Is Why Greenwich Roofs Leak — Here's the Difference

What Separates a Weatherproof Skylight System From One That Fails Within Three Winters

Most skylight leaks in Greenwich aren't caused by the unit itself — they're caused by flashing that was installed by crews whose primary expertise is window glazing rather than roofing. A window installer applies residential sealing techniques to what is fundamentally a roofing penetration problem, and the gap between those two skill sets shows up the first time a nor'easter drives wind-loaded rain across Fairfield County from the Long Island Sound. The curb height is wrong, the step flashing doesn't integrate with the shingle courses above it, and the counter-flashing wasn't embedded correctly — each gap individually manageable, collectively a reliable leak point.

APEX Roofing and Solar treats every skylight installation in Greenwich as a roofing project that happens to add natural light, not a lighting upgrade that happens to touch the roof. Each installation begins with an evaluation of the target roof plane's slope, existing shingle or slate condition, framing layout, and interior moisture management capacity. The flashing system is specified to the roofing material type — step and counter-flashing integrated differently for asphalt shingles than for standing-seam metal — and curb height is set to code minimums plus a margin appropriate for Connecticut's snow accumulation patterns.

What Proper Skylight Integration Actually Requires

Greenwich's older housing stock — much of it featuring slate, cedar shake, or complex multi-plane rooflines — presents integration challenges that standardized skylight installation kits aren't designed to address. Curb-mounted skylights on slate roofs require lead or copper flashing fabricated to the specific slate thickness and exposure, not aluminum tape-and-sealant approaches that deteriorate within a few freeze-thaw seasons. Deck-mounted units on low-slope asphalt roofs require extended ice-and-water shield coverage around the entire perimeter, not just the standard uphill triangle specified for steeper pitches.

When installation is handled by professionals who understand both the skylight product and the roofing system it penetrates, you gain a light source that transforms a dark interior space without introducing the moisture risk that sends homeowners back to contractors for leak repairs within three years. Ventilating skylights add passive airflow that reduces summer cooling loads in upper floors — a measurable benefit in Greenwich homes where upper-story bedrooms accumulate heat. Free inspections assess placement feasibility, structural requirements, and integration specifics for each project before any commitment is made.

What to Evaluate Before Choosing a Skylight Installer

The decision about who installs your skylight matters as much as which skylight you select. Greenwich homeowners who apply these criteria before signing a contract avoid the installation failures that generate leak repairs within a few years of completion:

  • Confirm the installer has documented roofing experience — not just window or glazing credentials — since the penetration is a roofing problem first
  • Ask whether flashing is specified to your roofing material type or applied as a generic waterproofing product regardless of substrate
  • Verify curb height meets Connecticut code minimums and accounts for Greenwich's snow accumulation at the roofline
  • Confirm ice-and-water shield coverage extends fully around the skylight perimeter, not just on the uphill side as minimum standards allow
  • Ask what the condensation management plan is for the interior finish — unaddressed condensation causes ceiling staining even when the exterior flashing is sound

An installer who can answer each of these questions with specific technical detail rather than general reassurances is demonstrating the roofing knowledge that skylight installation actually requires.
