“We had three contractors out. Tom was the only one who climbed up on the first visit. He showed us exactly where the old shingles were failing around the flashing and explained why it mattered. The crew finished a day early, cleaned up better than our landscaper, and the roof looks incredible. Worth every dollar.”

Long Island Roofing, Built to Last Since 2014.
We are a Melville crew that does one thing — Long Island roofing — on the same Capes, Colonials, Hi-Ranches, and Split Levels we grew up around. Roof replacement, roof repair, flat roofing, and standing seam metal across every town in Nassau and Suffolk County. 1850+ Long Island roofs since 2014, GAF Master Elite certified, and we still pick up the phone.

Six quick questions. We will call you back within 4 business hours. No sales pitch, ever.
Roofing done right. That is the whole menu.
We do not chase siding, windows, or kitchens. We install and repair roofs on Long Island homes, and we have gotten pretty good at it.
Tuesday at 8 means Tuesday at 7:50.
We have broken this rule once in the last decade and still talk about it. Most roofing complaints online start with “they never showed up.” That will not happen here. If you would rather talk to a human than fill out a form, here is the number.
1850 roofs. Same towns. Real photos.
Every one of these is a Long Island home we roofed. The “before” shot is the day we pulled up. The “after” is the day we drove away. No staging, no filters.

Roofing is our entire business
We do not chase siding, windows, or kitchens. Just roofing. A crew on its 1850th job works differently from one on its 10th, and you will see it in the flashing detail.

The crew lives here
Every person on our trucks lives on Long Island. Tom grew up in Melville. The crew has run LI jobsites for over a decade. When we say we know Nassau and Suffolk, we mean we know which supply house stocks the right ridge vent.
What the neighbors say.
“I got four quotes, read every Google review twice, and called two of their references. LI Roofing was not the cheapest. They were the ones who answered the phone, showed up when they said they would, and did not move the price after we signed. I would hire them again tomorrow.”
“Our cape needed a new roof and everyone else wanted us to go with basic 3-tab because 'it is cheaper.' Tom walked us through architectural vs metal for 40 minutes on the phone, told us honestly we would be happier with standing seam given how long we plan to stay, and he was right. Two years later and it still looks brand new.”
Long Island Roofing Company — GAF Master Elite, Licensed Nassau & Suffolk.
LI Roofing Co. is a full-service Long Island roofing company serving Nassau and Suffolk County since 2014. We install and repair every roof type on Long Island — asphalt shingles, architectural shingles, standing seam metal, and flat roofing systems — with the same licensed crew on every job from Mineola to Montauk.
As a GAF Master Elite contractor — a status held by fewer than 3% of roofing companies in the U.S. — we can offer the Golden Pledge Limited Warranty: 25-year coverage on both materials and workmanship, backed by GAF directly. CertainTeed SELECT ShingleMaster status gives the same comprehensive coverage for CertainTeed systems. These warranties travel with the home; they transfer to the next owner, which adds real value when you sell.
Long Island roofing requires contractors who understand the local environment. Nassau and Suffolk homes face some of the harshest conditions on the East Coast: coastal nor'easters with 80+ mph gusts, freeze-thaw cycles that shorten shingle life, salt air on South Shore and North Shore waterfront properties, and standing-water risk on flat-roof ranch sections built in the 1950s and 1960s. Our crew has worked these conditions for 12+ years. We know which products hold up and which ones fail at the 5-year mark.
We are licensed in both Nassau County (HIC #H2815200000) and Suffolk County (HIC #53241-H). Most roofing companies on Long Island are licensed in one county or the other. We are licensed in both, which matters because Nassau and Suffolk building departments have different permit requirements, different inspection processes, and different wind-load standards for roofing installations.
Roofing materials we install across Long Island.
Every Long Island home is different. A 1950s Levittown cape has different needs than a 2005 colonial in Commack. We install four primary roofing systems and help you match the right material to your budget, aesthetic, and how long you plan to stay.
Asphalt Shingles (3-Tab)
The most economical option for Long Island roofing. 3-tab shingles provide reliable wind and weather protection at the lowest cost per square foot. Best for budget-conscious homeowners, rental properties, or homes you plan to sell within 5-10 years. 25-year manufacturer warranty.
$7,500 – $12,000 installed (typical Long Island home)
Architectural Shingles
The most popular roofing material on Long Island — roughly 75% of our installations. Dimensional profile, superior wind resistance (130 mph+), and a lifetime manufacturer warranty. GAF Timberline HDZ and CertainTeed Landmark are our go-to lines. They handle Long Island nor'easters, summer heat, and salt air better than 3-tab at a modest price premium.
$9,500 – $16,500 installed (typical Long Island home)
Metal Roofing (Standing Seam)
The premium long-term investment for Long Island homeowners who plan to stay 20+ years. Standing seam metal lasts 50-70 years, sheds snow and ice effortlessly, and withstands 140+ mph winds — critical during hurricane season on Long Island. Energy efficient (reflects solar heat, reducing cooling costs 10-25% in Nassau and Suffolk summers). Available in 20+ colors. 40-50 year warranty.
$18,000 – $35,000 installed (typical Long Island home)
Flat Roofing (TPO / EPDM)
Essential for Long Island's many low-slope ranch extensions, dormers, sunroom additions, and commercial buildings. TPO (thermoplastic polyolefin) is our primary recommendation for new flat roofs — energy-efficient white membrane, heat-welded seams, and excellent ponding resistance. EPDM (rubber) is a proven budget option. Modified bitumen for areas that see foot traffic. 20-30 year warranties.
$8,000 – $18,000 installed (typical Long Island flat section)
Long Island Roofing Cost Factors
Roofing costs on Long Island are influenced by factors unique to Nassau and Suffolk County. Understanding these helps you evaluate quotes from any Long Island roofing company:
Warranty Protection for Long Island Roofs
A roof warranty on Long Island matters more than most places because our weather is harder on roofing systems — salt air from the Sound and the Atlantic, nor'easters with 60+ mph gusts, summer heat and humidity that accelerate granule loss. We provide three layers of protection on every Long Island roofing job:
- Manufacturer material warranty: 25 years (3-tab) to lifetime (architectural shingles) to 40-50 years (metal). Covers defects in the roofing material itself.
- Manufacturer system warranty (GAF Golden Pledge): Available only through GAF Master Elite contractors like us. Covers materials AND installation workmanship for 25 years. Fully transferable to the next homeowner — a real selling point for Long Island real estate.
- LI Roofing Co. workmanship warranty: 10 years, every job. If the roof fails because of how we installed it, we fix it at zero cost to you.
Questions we get every week.

Long Island roofing has specific requirements that most mainland contractors don't know. Every Nassau and Suffolk town runs its own building department — permits are mandatory for full replacements and are not transferable across county lines. Nassau HIC and Suffolk HIC licenses are separate credentials; a contractor licensed in one county cannot legally work in the other. North Shore Long Island roofing on Sound-facing slopes in Huntington, Lloyd Harbor, Smithtown, and Kings Park requires 6-nail high-wind installation — standard 4-nail doesn't hold in sustained 55-70 mph nor'easter gusts. Long Island's mature suburban tree canopy drives algae and moss buildup on shaded north-facing slopes within 5-8 years, so algae-resistant copper-granule shingles aren't optional on wooded lots — they're practical. Labor rates, permit fees in every town, and disposal costs at Long Island transfer stations push Long Island roofing costs 15-25% above national averages. LI Roofing Co. holds both Nassau and Suffolk HIC licenses, is GAF Master Elite certified, and has completed 700+ Long Island roofing projects since 2014.
