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.
No sales pitch. No “today only” nonsense. We inspect your roof, we give you a real number, you think about it.
Six quick questions. We will call you back within 4 business hours. No sales pitch, ever.
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.
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.
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.
Tuesday at 8 means Tuesday at 7:50. We have broken this rule once in the last decade and Tom still talks about it. Most roofing complaints online start with 'they never showed up.'
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.
We quote you a number. That is the number. No 'today only' discount, no manager call, no pressure to sign tonight. If you need a week to think, take a week.
Nassau HIC #H2815200000. Suffolk HIC #53241-H. $2,000,000 liability. Workers comp on every crew member. GAF Master Elite. CertainTeed SELECT. BBB A+.
No AI on our site. No call center. Call between 7am and 6pm Monday through Saturday and you get Maria in the office or Tom in the truck. Nights and weekends, leave a message, we call back.
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.
“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.”
“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.”
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.
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.
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)
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)
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)
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)
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:
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:
If your question is not here, call us. Most questions we answer by phone take five minutes.
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.
LI Roofing Co. is a Long Island roofing company serving all of Nassau and Suffolk County. We install asphalt shingles, architectural shingles, standing seam metal, and flat roofing (TPO and EPDM) on Long Island homes that span every era from 1940s Levittown capes to 2000s colonials in Commack and Smithtown. Our crew handles the full range of Long Island roofing conditions: nor'easter storm damage on south-facing slopes, ice dam prevention on north-facing homes near Long Island Sound, coastal salt air corrosion of flashing along the South Shore and North Shore, and the flat roof ponding issues common on Long Island ranch extensions and commercial buildings.
Most Long Island homeowners who call us are replacing a roof that was installed in the 1990s or early 2000s. That generation of roofing is now 20-30 years old and at or past its design life. Architectural shingles installed today will carry a lifetime manufacturer warranty and survive another 30 years of Long Island weather — nor'easters, summer humidity, salt air, and the occasional hurricane track that clips Nassau or Suffolk County. We dimension every job around those three Long Island-specific failure modes: wind uplift, moisture infiltration, and flashing corrosion.
As a GAF Master Elite contractor and CertainTeed SELECT ShingleMaster, we provide system-level warranties not available from uncertified roofers. The GAF Golden Pledge warranty covers both materials and workmanship for 25 years and transfers to the next homeowner — a genuine selling point in Long Island's real estate market. We are Nassau HIC licensed, Suffolk HIC licensed, fully insured, and have pulled roofing permits in dozens of towns and villages across both counties since 2014. When you hire a Long Island roofing company, make sure they are licensed in your specific county and pull your permit — not just "insured and experienced."
Long island roofing is a specific discipline — not just “roofing” in a generic sense. Nassau and Suffolk County homes were built almost entirely between 1945 and 1980, which means the dominant housing types are Levittown capes, South Shore split-levels, North Shore colonials, and Huntington-to-Smithtown hi-ranches. Most of these homes have been re-roofed once already, and that second-generation roof is now at or past its 25-year design life. The long island roofing replacement cycle is in full swing.
Three environmental factors define how long island roofing performs differently from inland markets: nor'easter wind patterns that drive rain under improperly seated shingles on south-facing slopes; salt air exposure on both the North Shore (Long Island Sound) and South Shore (Atlantic, Great South Bay) that corrodes standard galvanized flashing in as little as 6 years; and the ice dam risk that comes with Long Island's periodic hard freezes and the poor attic insulation common in mid-century construction. We design every long island roofing installation around these three failure modes.
Long Island's permit landscape adds another layer. Nassau County has three towns and dozens of incorporated villages, each with its own building department, fee schedule, and inspection process. Suffolk County has ten towns. We pull roofing permits in every one of these jurisdictions and have done so on 1850+ jobs since 2014. When comparing long island roofing companies, confirm that your contractor pulls permits in your specific town — not just “Long Island.” A contractor who skips the permit to save time is not protecting you.

There are hundreds of roofing companies on Long Island ranging from one-truck operations to large regional contractors with multiple crews. The most important credentials to verify before signing any contract: (1) Nassau County or Suffolk County HIC license — not just a New York State contractor license, but the county-specific Home Improvement Contractor registration required by Nassau and Suffolk for work over $200; (2) GAF Master Elite or CertainTeed SELECT ShingleMaster status, which restricts system-level warranties to fewer than 3% of all roofing companies nationwide; and (3) active workers' compensation and general liability coverage verified directly with the carrier, not just a certificate you can't validate. LI Roofing Co. holds Nassau HIC #H2815200000, Suffolk HIC #53241-H, GAF Master Elite status, and CertainTeed SELECT ShingleMaster certification. We carry $2M general liability and full workers' comp. You can verify every one of those on a phone call before we arrive.
Price is not the primary differentiator among reputable roofing companies on Long Island — warranty coverage is. A GAF Master Elite contractor can offer the GAF Golden Pledge 25-year warranty covering both materials AND workmanship. An uncertified roofer can only offer the GAF manufacturer warranty, which covers materials only. That labor warranty matters at year 8 when a flashing detail fails — the Golden Pledge covers the repair cost, the uncertified warranty leaves it entirely to you.
Roof replacement on Long Island costs $9,500–$28,000 for most single-family homes depending on size, pitch, and material. A typical 1,800–2,200 sq ft Nassau or Suffolk County colonial with a standard 4:12 pitch runs $12,500–$18,500 for GAF Timberline HDZ architectural shingles including permit, tear-off of old shingles, new underlayment, ice and water shield on the first 3 feet (required by NYS code), and disposal. Nassau County permit fees run $125–$300 depending on the town. Suffolk County varies by town: Town of Babylon charges $175 plus inspection; Huntington runs $150–$250.
The roof replacement process on Long Islandincludes: free in-home estimate + written quote (same-day), permit filing, crew mobilization (typically 1–3 weeks after contract), one-day tear-off and installation for most homes, same-day cleanup and magnet-sweep, and final inspection coordination. We sequence every Long Island roof replacement around the weather — we don't start a project where we can't finish the same day. Material delivery is scheduled for the morning of installation to avoid theft risk.
Emergency roof repair on Long Islandmeans different things depending on the season. In summer, it's the nor'easter or tropical storm that peeled back a ridge cap and left exposed sheathing. In winter, it's the ice dam that backed up under the shingles and is now dripping through the ceiling at 2am. In either case, you need a licensed roofing contractor on-site the same day — not a handyman, not a tarp-and-wait, and not a voicemail.
LI Roofing Co. provides same-day emergency roof repair response across Nassau and Suffolk County. Our emergency service covers: missing shingles after wind damage, active roof leaks with interior water intrusion, torn or lifted ridge caps, failed flashing at chimneys and skylights, ice dam leak investigation and temporary mitigation, and storm damage triage for insurance documentation. We carry major shingle colors on every truck — not just a patchwork of whatever was left in the warehouse.
Emergency roof repair cost on Long Island: Most emergency repairs — replacing a section of wind-damaged shingles, re-flashing a chimney, sealing an active leak at a valley — run $450–$1,800 depending on scope. Full sections requiring structural decking repair run higher. We give you a written scope and price before we start, even on emergency calls. If the damage qualifies for a homeowner's insurance claim (most wind and hail damage does), we document with photos and measurements in the format your adjuster needs. Nassau County homeowners: call us directly rather than a "storm chaser" crew — out-of-state contractors who descend after major storms have no Long Island license and no accountability if the repair fails. See our complete Long Island roof repair cost guide for full pricing across all repair types.
The best Long Island roofers share four traits that distinguish them from the low-bid operators who show up after every storm: they are licensed in your specific county (not just “insured”), they pull your permit and handle the inspection, they use manufacturer-certified installation techniques that protect warranty validity, and they give you a written fixed-price contract before a single shingle is removed. We have built our reputation in Nassau and Suffolk County on exactly those four things since 2014. 1850+ Long Island roofs completed. GAF Master Elite status. CertainTeed SELECT ShingleMaster certified. Licensed in both counties. We pull permits in every Long Island town.
