Understanding Skylights

More Than Just a Hole in the Roof

A skylight is a roofing system element, not just a window. It requires structural modification of the roof deck, proper curb construction or deck mounting, flashing that integrates with the existing roof membrane, and interior finishing. Done poorly, a skylight becomes the #1 source of leaks in a building. Done right, it lasts decades without a single drop inside.

Brooklyn's mix of flat roofs, pitched brownstone roofs, and old rowhouses demands a contractor who knows all roof types. MLM Construction Group has installed skylights on every type of Brooklyn building, from EPDM flat roofs in Flatbush to pitched shingle roofs in Bay Ridge.

We pull all required NYC DOB permits, install fully waterproofed flashing systems, and provide written warranties on both the skylight and the surrounding roof work. Your skylight will let in light, not water.

Benefits of a Skylight

  • ✓ Up to 30% more natural light than a standard window
  • ✓ Reduces electricity costs: less artificial lighting needed
  • ✓ Venting skylights improve air circulation and reduce humidity
  • ✓ Adds 5 to 10% to property resale value
  • ✓ Transforms dark interior spaces (hallways, bathrooms, top floors)
  • ✓ Passive solar heating in winter reduces heating costs
Types of Skylights

The Right Skylight for Your Brooklyn Property

🔲

Fixed Skylights

Non opening skylights designed purely for natural light. The most durable and leak resistant option. Ideal for living rooms, offices, and any space that needs light without ventilation. Available in flat glass, domed, and pyramid designs.

🌬️

Venting Skylights

Open manually or electrically to allow airflow. Perfect for kitchens, bathrooms, and top floor bedrooms where heat and humidity accumulate. Velux venting skylights with rain sensors automatically close in bad weather.

🌀

Tubular Skylights

Small diameter tubes with a reflective interior that channel sunlight into tight spaces, hallways, closets, and first floor rooms. Minimal roof penetration, fast installation, and extremely watertight. Excellent for brownstone middle floors.

🏠

Curb Mounted Skylights

Designed specifically for flat roofs, the most common Brooklyn roof type. The skylight sits on a raised wooden or metal curb, which is fully flashed and waterproofed. Offers the best water protection on flat or low-slope roofs.

📐

Deck Mounted Skylights

Installed directly into pitched or sloped roofs without a separate curb. Common on brownstone rooftops and angled sections. The integrated flashing kit makes these slim and attractive while maintaining full waterproofing.

🔧

Skylight Repair & Replacement

Skylight Questions

Skylight Installation and Leak Questions

How much does skylight installation cost in Brooklyn? +
A fixed curb mounted skylight installed on a flat roof runs $1,400 to $3,500 including flashing and interior finish at the opening. A venting or motorized unit runs $2,500 to $5,500. Cutting a brand new opening where none existed adds framing and interior work, usually $800 to $2,000 on top. Replacing an existing unit in the same opening is the cheapest version of this job.
Why is my skylight leaking? +
Three causes cover nearly all of them. The flashing kit was never installed or was replaced with caulk, the gasket around the glass has aged out, or what you are seeing is not a leak at all but condensation running off cold glass. If it only drips on cold dry days it is condensation and the fix is ventilation, not roofing. We tell you which one it is before quoting.
Can a skylight be installed on a flat roof? +
Yes, and on Brooklyn flat roofs it is the normal way. The unit sits on a built up curb raised above the roof plane so water runs around it rather than sitting against the glass. A skylight set flat into the membrane without a curb will pond and leak eventually, which is why we will not install one that way.
How long does a skylight last? +
The unit itself gives 20 to 30 years. The glass seal typically goes first at 15 to 20 years and shows as fogging or moisture between the panes. The flashing is what fails earliest if it was installed poorly, and it can be replaced without replacing the skylight if the frame is still sound.
Do I need a permit for a skylight in Brooklyn? +
Cutting a new opening in a roof is structural work and requires a DOB permit. Replacing an existing skylight in the same opening at the same size normally does not. Buildings in landmarked districts need Landmarks approval when the unit is visible from the street. We confirm which applies to your address before any work is scheduled.
