Professional Flat Roof Skylights Installation & Repair Services
Installing flat roof skylights in Queens properties typically runs between $800-$2,500 per skylight, depending on the size and type you choose. Look, I've been installing skylights on flat roofs across Queens for over two decades now, and I can tell you that most homeowners are surprised by how much natural light these units bring into their homes - especially in those darker middle floors of Astoria row houses.
The thing about skylight for flat roof installations is that they're not your typical sloped roof job. Flat roofs require specialized curb-mounted systems that create proper drainage and weatherproofing. Just last week on 31st Street, we installed three Velux flat roof skylights for a homeowner who thought it couldn't be done on her 1960s brick colonial.
Can You Put a Skylight on a Flat Roof? Absolutely
Can you put a skylight on a flat roof? This is probably the most common question I get from Queens homeowners. The answer is yes, but it requires the right approach and equipment. Flat roof skylights use a different mounting system than traditional sloped roof units - they need a raised curb system that sits above the roof line to prevent water infiltration.
The best skylight for flat roof installations depends on your specific needs. For most Queens homes, I recommend either fixed or venting skylights with double or triple glazing. The salt air from the East River and Flushing Bay means we always spec marine-grade hardware and weatherstripping.
Types of Skylights That Will Work on a Flat Roof
There are several skylights that will work on a flat roof, each with specific advantages:
- Fixed flat skylights - $800-$1,500 installed
- Venting skylights - $1,200-$2,200 installed
- Tubular skylights - $650-$1,100 installed
- Walk-on glass skylights - $2,000-$4,500 installed
My foreman Carlos always says the fixed units are workhorses - they don't have moving parts to break down in our harsh Queens winters. But if you need ventilation in a bathroom or kitchen area, the venting models are worth the extra cost.
Installation Process for Skylight on Flat Roof
Installing a skylight on flat roof systems requires careful planning and execution. We start by cutting the roof opening, then install a prefabricated curb that raises the skylight above the roof surface. This curb system is critical - it's what prevents water from pooling around the unit.
The flashing details are where most contractors mess up flat roof skylight installations. We use a two-stage flashing system with base flashing integrated into the roofing membrane and counter-flashing that ties into the skylight frame. After 2,000+ roofs in Queens, I can tell you that cutting corners on flashing always comes back to bite you.
Here's something most people don't realize: the skylight flat roof installation needs to account for thermal movement. Flat roofs expand and contract significantly more than sloped roofs, especially with EPDM or modified bitumen systems. We use flexible sealants and expansion joints to accommodate this movement.
Drainage Considerations for Skylights for Flat Roof
Water management is everything when it comes to skylights for flat roof applications. Queens gets about 45 inches of rain annually, plus snow load in winter. Every skylight installation needs proper cricket installation to direct water around the unit.
I can't tell you how many times I've been called to fix leaking skylights that were installed without proper drainage planning. The skylight itself might be perfectly waterproof, but if water pools around the curb, you're asking for trouble.
Oh, and another thing about drainage - make sure your contractor coordinates with your roof drain locations. We always check the existing drainage pattern before cutting any openings. Sometimes adding a skylight on a flat roof means modifying the drainage system.
Glass Flat Roof Skylights vs. Other Materials
Glass flat roof skylights offer the best clarity and longevity, but they're not always the right choice for every application. Polycarbonate units cost about 30% less and provide better impact resistance - important consideration in Queens where hail isn't uncommon.
For commercial applications or areas where people might walk overhead, tempered or laminated glass is code-required. These skylight window on flat roof units can handle significant loads, but they cost considerably more - usually $3,000-$6,000 installed for walk-on models.
Energy Efficiency and Sky Window Flat Roof Options
Modern sky window flat roof units offer excellent energy efficiency when properly installed. We typically recommend double-pane Low-E glass with argon fill for Queens' climate. The energy savings on heating and cooling usually offset the installation cost within 7-10 years.
The key is proper sizing and placement. Too many skylights and you'll have heat gain issues in summer. Too few and you won't get the natural lighting benefits you're paying for. For most Queens homes, I recommend no more than 10-15% of floor area in skylight coverage.
Maintenance and Repair of Flat Skylight Roof Systems
Maintaining your flat skylight roof system isn't complicated, but it requires regular attention. I tell all my customers to check the seals and flashing twice yearly - once before winter and once after the spring thaw.
The most common issues we see are:
- Clogged drainage around the curb
- Deteriorated sealant at the frame
- Condensation issues due to poor ventilation
- Cracked glazing from thermal stress
Repair costs typically range from $275 for minor seal work to $1,800 for complete glazing replacement.
