Skylights bring natural light into homes and commercial buildings, but proper installation and sealing are essential to prevent leaks. Double A Skylight is a licensed and insured skylight contractor in Long Island, serving homeowners and commercial property owners across Nassau and Suffolk Counties.

The team handles skylight installation, repairs, replacements, and leak repairs, identifying the source of the problem before recommending an appropriate solution.

Core Skylight Services
Double A Skylight handles these types of work for residential and commercial properties:
• Skylight installation, from planning and placement to final sealing
• Skylight repair, including cracked glass, worn seals, and flashing
• Skylight replacement for aging or damaged units
• Skylight leak repair, including emergency repairs

Skylight Repair or Replacement? The Inspection Comes First
Not every skylight needs to be replaced. The company starts by inspecting the skylight and the roof around it. A leak can come from worn seals, flashing that has deteriorated, roof damage next to the unit, or a poor installation from years ago, not only from the skylight itself.

Based on the inspection findings, the company explains whether a repair will solve the problem or whether replacement makes more sense.

Replacement is usually worth considering when a skylight has repeated leaks, cracked glazing, fogging between glass panes, deteriorated frames, or significant age.

How Leaks and Replacements Are Handled
Leak repair can mean resealing a unit, replacing flashing, or repairing the roofing materials around it. Common warning signs include ceiling stains, dripping during rain, damp spots near the skylight, and fogging between glass panes. Small leaks tend to grow into bigger problems, so the company advises against waiting.

A replacement follows a set order:
Evaluate the existing skylight and roof.
Remove the old unit in a way that protects the roof structure.
Install the new one with attention to alignment, flashing, and sealing.
Double-check the waterproofing before cleanup.

Skylight Types for Different Spaces
The company works with four skylight types. Fixed skylights bring in daylight without ventilation. Venting skylights add airflow and can help reduce moisture in kitchens and bathrooms, and they come in manual, electric, and solar models.

Sun tunnels suit hallways, closets, and other small or enclosed spaces where a full skylight is not practical. Flat roof skylights are designed for flat or low-slope roofs, where proper drainage and sealing matter most.

Residential and Commercial Projects
The company’s services cover homes, offices, retail properties, and other commercial buildings. Many standard installations and replacements can be finished within a day. Larger, multiple-unit, or more complex projects may take longer, depending on the roof.
Materials and sealing methods are chosen with Long Island weather in mind, including heavy rain, snow, and heat.
Cost depends on the skylight type, size, roof configuration, and installation requirements. For that reason, estimates are provided after an inspection and are specific to each project. Consultations are free.
