Transform your home with natural light and ventilation. Alter Phase Roofing offers expert skylight installation, repair, and replacement services.
A leaking skylight can cause thousands in water damage — and a poorly installed one can too. Alter Phase Roofing brings licensed expertise, transparent pricing, and a workmanship warranty to every skylight project in Staten Island.
From a simple seal repair to a full new skylight installation, Alter Phase Roofing handles every aspect of the job — including permits, flashing, and interior finishing. We serve homeowners across all of Staten Island with same-day emergency availability.
Full skylight installations on pitched and flat roofs. We handle structural cutting, waterproofing, flashing, and the interior light well from start to finish.

Upgrade old, fogged, or inefficient skylights to modern energy-efficient units. We remove the old unit cleanly and ensure a weathertight installation of the new one.
Damaged or lifted flashing is the #1 cause of skylight leaks in Staten Island. We restore complete waterproofing integration between your skylight and roof deck.
Manual and electric venting skylight installation and repair. We service Velux, Fakro, and other major brands, including motor and sensor replacements.
Storm damage, sudden leaks, or broken glass — our team responds fast to protect your home from further water intrusion. Emergency service available.
Choosing the right skylight type for your home, roof pitch, and goals makes a significant difference in performance, cost, and long-term satisfaction. Here's what we install and service:
| Skylight Type | Best For | Staten Island Note | Maintenance Level |
|---|---|---|---|
| Fixed Skylight | Living rooms, hallways, stairwells — anywhere you want light without ventilation | Most common on Staten Island pitched roofs; lowest cost option | Low |
| Venting / Fresh Air Skylight | Kitchens, bathrooms, master bedrooms — light plus airflow | Especially valuable for older Staten Island homes with limited ventilation | Medium |
| Tubular Skylight (Sun Tunnel) | Dark hallways, closets, bathrooms — compact spaces where a full skylight won't fit | Great option for row homes and attached properties common on the island | Very Low |
| Flat Roof Skylight (Curb-Mounted) | Flat or low-pitch roofs — commercial buildings, modern additions, top floors | Common for Staten Island homes with flat or modified bitumen roof sections | Medium-High |
| Deck-Mounted Skylight | Pitched roofs (most residential) — low-profile, flush with roof surface | Standard installation on most Staten Island pitched-roof homes | Low |
We install and service all major brands including Velux, Fakro, Wasco, and Supreme. Not sure which is right for your home? Call us — we'll advise you honestly based on your roof type and goals.
This is the question we get most often — and the honest answer depends on your skylight's age, the type of damage, and the cost comparison. Here's the straightforward framework we use:
Not sure which applies to your skylight? We'll inspect it for free and give you a straight answer.
Request Free EstimateNYC labor rates run 15–25% above national averages — so national cost guides often understate what you'll pay here. Below are realistic 2025 price ranges for Staten Island homeowners, based on typical project scopes. Every project is quoted individually in writing with no hidden fees.
We provide free, detailed written estimates — no surprise charges at completion. Financing options may be available for larger projects.
Catching skylight problems early prevents minor repairs from becoming expensive water damage claims. Watch for these warning signs — and call us if you spot any of them:
Brown stains or water on the ceiling near your skylight mean water is entering — don't wait. Even small leaks can cause structural damage and mold.
Condensation or fogging between panes means the insulated glass unit seal has failed. The glass must be replaced — it will only worsen over time.
Feeling cold air coming through around your skylight? The weather stripping or frame seal has deteriorated — this also raises your heating costs significantly.
Flashing failure is the leading cause of skylight leaks in Staten Island. Visible rust, gaps, or lifted metal around the skylight frame needs immediate attention.
Physical damage to the glass or acrylic dome compromises weatherproofing and, in some cases, structural integrity. Don't leave cracked glass unaddressed.
Most skylights last 15–25 years. Staten Island's coastal humidity and harsh winters accelerate wear. If yours is approaching this age, schedule an inspection.
We make the process as straightforward as possible — from your first call to the final walkthrough. Here's what to expect when you work with Alter Phase Roofing:

Skylight repair in Staten Island typically ranges from $450 to $1,500, depending on the type of damage, skylight size, and roof accessibility. NYC labor rates run 15–25% above the national average of around $955. Minor resealing jobs start at the low end; flashing replacement or glass repair runs higher. We provide free, itemized written estimates with no hidden fees.
Repair if your skylight is under 15 years old, damage is isolated to seals or flashing, and repair costs less than half of replacement. Replace if it's 15–25+ years old, has multiple leaks, fogged glass (failed seal), or is significantly reducing your home's energy efficiency. Our licensed technicians will give you an honest recommendation after a free inspection.
Skylight installation is a roofing job. Because the skylight penetrates the roof deck and requires waterproof flashing integration, a licensed roofing contractor is the right choice. Window companies specialize in wall openings, not roof penetrations. Alter Phase Roofing handles the full scope: roof opening, flashing, waterproofing, and interior light well finishing.
A standard skylight installation on a Staten Island home takes 1 to 2 days. This includes cutting the roof opening, installing the skylight unit, applying flashing, and completing the interior light well. More complex projects — such as venting skylights on flat roofs or multiple-unit installs — may take an additional day.
It depends on the cause. Most homeowners policies cover skylight damage caused by sudden events like storms, hail, or falling debris. Leaks resulting from age, wear, or poor maintenance are typically not covered. We recommend documenting damage with photos immediately and contacting your insurer before repairs. We're experienced in working alongside insurance claims on Staten Island properties.
Velux is the industry gold standard — widely available, well-supported, and backed by a strong warranty. Fakro offers excellent value at a slightly lower price point. Wasco and Supreme are solid alternatives for specialty or flat-roof applications. We install and service all major brands and can recommend the best fit for your roof type and budget.
Many skylight leaks can be repaired without full replacement. Common fixable issues include failed sealant, damaged or lifted flashing, cracked glazing, and deteriorated weather stripping. If the skylight frame itself is cracked, the glass unit has failed (foggy between panes), or the unit is very old, replacement is usually the smarter long-term investment. We'll always tell you which option makes more sense for your situation.
Quality skylights last 15 to 25 years with proper maintenance. Velux units with good flashing and annual inspections often reach the top of that range. Staten Island's coastal humidity and freeze-thaw cycles can accelerate seal and flashing wear, so annual inspections are particularly valuable here. Once a skylight passes 20 years, replacement is often more cost-effective than repeated repairs.
Yes — strategically placed skylights can increase home value and accelerate sale time by enhancing natural light, making spaces feel larger, and improving energy efficiency. In Staten Island's competitive real estate market, modern energy-efficient skylights in kitchens, master baths, and living rooms are particularly attractive to buyers.
In most cases, yes. New skylight installations in New York City require a permit from the NYC Department of Buildings. As a licensed NYC contractor (License #2098943), Alter Phase Roofing handles the permit process on your behalf. Permit costs vary but are typically factored into your project estimate upfront — no surprises.
