Professional Curb Mounted Skylight Flat Roof Installation Services

When you're looking at bringing natural light into your Queens building through a flat roof, curb-mounted skylight installation typically runs between $800-$2,500 per unit depending on size, materials, and complexity. That's including the curb assembly, proper flashing, and weatherproofing - which honestly, on flat roofs in this area, you can't skimp on.

Look, I've been installing skylights on flat roofs across Queens for over fifteen years now, and I can tell you that curb-mounted systems are absolutely the way to go for our climate. Just last month we did a beautiful installation on a warehouse in Long Island City where the owner wanted to cut down on electricity costs. The curb mounted skylight flat roof system we installed is already saving them hundreds monthly.

Why Curb-Mounted Skylights Work Best on Flat Roofs

Here's the thing about flat roofs - and I'm talking to building owners from Astoria to Jamaica - you need that raised curb to handle our weather. The curb creates proper drainage, elevates the skylight above standing water, and gives us a solid attachment point that won't compromise your roof membrane.

Most of the skylight problems I get called to fix? They're from improper installations where someone tried to cut corners. Water damage, leaks around the flashing, membrane failure - all preventable with proper curb-mounted skylight installation on flat roofs.

At Flat Masters NY, we build every curb custom. Standard heights range from 4 to 12 inches, but we've gone higher when drainage or snow load requires it. The curb gets anchored directly to your roof deck, then we tie the new flashing into your existing membrane system.

Installation Process and Costs Breakdown

A typical curb mounted skylight flat roof installation breaks down like this:

• Curb fabrication and materials: $200-$400
• Skylight unit (depending on size): $300-$1,200
• Professional installation: $300-$900
• Flashing and weatherproofing: $150-$300

Those numbers can shift based on your specific situation. A 2x4 foot skylight on a basic EPDM roof? You're looking at the lower end. But if you want a 4x8 foot unit with insulated glazing on a complex roofline, we're talking higher numbers.

The installation process takes most of our crew about 4-6 hours per skylight. We start by cutting the roof opening, then building and installing the curb assembly. The trickiest part is always the flashing integration - especially on older buildings where we're working with existing membrane systems that might be showing their age.

Common Problems We See (And How to Avoid Them)

I can't tell you how many emergency calls we get about leaking skylights. Nine times out of ten, it's because someone didn't properly flash the curb or used the wrong sealants for our weather conditions.

The salt air from the East River means we always use marine-grade sealants and stainless steel fasteners. Regular hardware store stuff just doesn't hold up. And in Queens, with our freeze-thaw cycles, expansion joints around the curb are critical.

Another issue? Improper curb height. Too low and you get standing water problems. Too high and you create wind uplift issues. We calculate the right height based on your specific roof's drainage patterns and local snow load requirements.

Material Choices That Matter

For the curb itself, we typically use pressure-treated lumber or aluminum depending on the application. Aluminum costs more upfront - maybe $100-200 extra - but it's worth it for longevity, especially near the water.

Skylight glazing options include:

• Single glazed acrylic: Most economical, good light transmission
• Double glazed polycarbonate: Better insulation, impact resistant
• Tempered glass: Premium option, best clarity and longevity

For commercial buildings, we often recommend polycarbonate. It handles thermal expansion better than glass and won't shatter if something hits it during a storm.

Local Code Requirements and Permits

In Queens, any skylight installation over 16 square feet requires a building permit. The application process usually takes 2-3 weeks, and inspections are required both during framing and after completion.

NYC building code requires specific wind load calculations for skylights, especially on buildings over three stories. We handle all the engineering and permit paperwork - it's included in our installation pricing because honestly, the paperwork side of this business can be more complex than the actual roofing work.

Fire code is another consideration. Commercial buildings often need skylights that can serve as emergency ventilation, which affects both sizing and placement.

Energy Efficiency and ROI

A properly installed curb mounted skylight can reduce your electric bill by 15-30% in areas that previously required artificial lighting during the day. On a 2,000 square foot warehouse space, that might translate to $200-400 monthly savings.

The payback period typically runs 3-7 years depending on your current energy costs and how much natural light the space gains. Buildings with high ceilings see the biggest benefit because the light spreads further.

We also install skylights with integral blinds or automated louvers for light control. These add about $300-600 to the project cost but give you much better control over heat gain during summer months.

Maintenance and Longevity

A quality curb-mounted skylight installation should last 20-25 years with minimal maintenance. The main thing is keeping the drains clear and checking the sealant annually.

We recommend cleaning the glazing twice yearly - spring and fall. Use mild soap and water, never abrasive cleaners that can scratch the surface. Scratched skylights look terrible and reduce light transmission significantly.

Every five years, have the flashing inspected. Small sealant failures caught early can be fixed for under $200. Wait until you have active leaks and you're looking at membrane repairs that can cost thousands.
