Metal roofing on Long Island typically costs $15,000–$54,500 installed and lasts 40-70 years — 2-3x the lifespan of asphalt shingles in the same coastal climate. The best system for most Long Island homes is 24-gauge aluminum standing seam (for salt-zone homes within 2 miles of the shore) or stone-coated steel (for homeowners who want the look of shingle or tile with metal performance). Every install is backed by GAF-partnered contractors, a pulled Nassau or Suffolk building permit, and a 10-year workmanship warranty on top of the 30-50 year manufacturer paint warranty.
Long Island’s climate punishes roofs: 3-5 nor’easters per year, salt air within 2 miles of the coast, 60-80 freeze-thaw cycles annually, and a 130 mph design wind speed in the coastal high-velocity hurricane zone. According to the National Roofing Contractors Association (NRCA), metal systems tested to UL 580 and ASTM E1592 outperform every shingle product on wind-uplift resistance — which is why metal is now the fastest-growing residential roofing category on Long Island. Manufacturer specs and finish warranties are documented in GAF’s TruSlate & metal roofing product line, which we install alongside certified independent metal-roof manufacturers.
We install four residential metal roofing systems on Long Island, each engineered for a specific combination of exposure, budget, and aesthetic. Choosing the right one starts with your home’s distance from the coast, roof pitch, and whether you’re retrofitting over existing asphalt or tearing off to the decking.
$12–$22 per sq ft installed · 50-70 year lifespan
The gold standard for Long Island. Vertical panels with concealed-fastener interlocking seams resist uplift at 140+ mph winds and shed salt water without corroding. Aluminum is mandatory for coastal homes in Long Beach, Sayville, Oyster Bay, and anywhere within 2 miles of salt water. 24-gauge galvalume steel works inland. Class A fire, Class 4 hail.
$8–$13 per sq ft installed · 40-60 year lifespan
Textured stone granules bonded to zinc-aluminum coated steel. Mimics the look of asphalt shingles, wood shake, or clay tile — perfect for historic districts like Garden City, Cold Spring Harbor, and Oyster Bay Cove where HOA or architectural review boards require traditional aesthetics. 120 mph wind rating, Class A fire, Class 4 hail.
$9–$14 per sq ft installed · 50+ year lifespan
Interlocking aluminum panels shaped like slate, shake, or architectural shingle. Light enough (0.6-0.8 lbs/sq ft) to install over a single layer of existing asphalt, saving 15-30% vs. tear-off. Popular choice in Melville, Dix Hills, and Jericho for homeowners who want metal performance without disturbing perfectly good decking.
$7–$10 per sq ft installed · 25-40 year lifespan
Ribbed galvalume panels with exposed screws. Best for barns, garages, carriage houses, and outbuildings — not typically specified for primary residences on Long Island because the exposed fasteners degrade faster in salt air and the panel profile reads as agricultural. Still the most affordable metal option when aesthetics are secondary.
The honest answer depends on how long you’re staying and where your home sits. For a full side-by-side including payback period, see our metal vs. asphalt shingles guide. Short version: metal wins on durability, wind, and lifecycle cost — asphalt wins on upfront price and neighborhood fit.
| Attribute | Metal (Standing Seam) | Architectural Asphalt |
|---|---|---|
| Installed cost (2,400 sq ft) | $28,000 – $38,000 | $11,000 – $18,000 |
| Long Island lifespan | 40-70 years | 15-25 years |
| Wind rating | 140+ mph (UL 580) | 110-130 mph (ASTM D7158 H) |
| Hail rating | Class 4 (UL 2218) | Class 3 typical, Class 4 premium |
| Fire rating | Class A (UL 790) | Class A (UL 790) |
| Cooling savings | 10-25% on reflective finishes | 0-5% |
| Insurance discount | 10-25% on wind premium | 0-5% |
| Manufacturer warranty | 30-50 year paint + substrate | 25-50 year (prorated) |
| Salt-air performance | Excellent (aluminum) | Degrades 20-30% faster vs. inland |
Data compiled from NRCA lifecycle studies, manufacturer specifications (GAF, CertainTeed, Owens Corning metal lines), and 150+ Long Island installations completed by Long Island Roofing Pros since 2011.
In our 15+ years installing both materials across Nassau and Suffolk County, metal wins in five specific scenarios. If one or more of these describes your home, the math on metal gets compelling — especially once insurance discounts and cooling savings are stacked.
1. You live within 2 miles of the coast.
Salt air accelerates asphalt granule loss by 20-30%. South Shore homes in Long Beach, Lido Beach, Atlantic Beach, Sayville, Bellport, and Westhampton — plus North Shore waterfront in Lloyd Harbor, Cold Spring Harbor, Centre Island, and Bayville — routinely see asphalt roofs fail at 12-15 years instead of 25. Aluminum standing seam ignores salt entirely.
2. You plan to stay 15+ years.
The standard asphalt payback window is 20 years. Metal’s break-even point on Long Island is typically year 14-16 once you factor in avoided replacement, insurance discounts, and 10-25% cooling savings. After that, metal prints money.
3. Your roof has complex pitches or architectural details.
North Shore colonials in Jericho, Woodbury, and Muttontown, plus Hamptons-style homes in the Pines Lake and Quogue areas, carry multiple dormers, valleys, and hip sections. Standing seam panels are custom-fabricated per pitch — no short shingles, no overlap failures, and no ridge-cap nail-pops after high wind events.
4. You’ve already filed 1+ wind/hail insurance claim.
Multiple claims raise your premium and can trigger non-renewal on shingle roofs. Many NY carriers (Allstate, State Farm, Travelers) offer 10-25% wind-premium discounts on Class 4-rated metal — sometimes recouping the cost difference in under 10 years on a high-exposure home.
5. Your attic is under-ventilated and your cooling bills hurt.
Reflective ENERGY STAR metal roofs reduce attic temperatures 20-40°F on a 90°F Long Island summer day. Homes in Dix Hills, Melville, and East Meadow with older 1960s-70s insulation and ductwork in the attic see the biggest benefit — 10-25% lower cooling bills June through September.
We install metal roofs across every Nassau and Suffolk County municipality — from the South Shore barrier islands to the Hamptons, and everywhere in between. A few town-specific notes that come up repeatedly in our estimate calls:
Metal Roof Melville, NY
Melville’s 2,400-3,500 sq ft colonials with complex multi-pitch roofs are textbook standing-seam candidates. Average metal roof installation Melville runs $32,000–$44,000 for a full tear-off with architectural-grade aluminum panels.
Metal Roof Installation Dix Hills, NY
Dix Hills homes built 1965-1985 often have perfectly sound decking but aging asphalt. Aluminum shingle retrofits over existing asphalt cost $22,000–$30,000 and preserve the decking while adding 50 years of roof life.
Metal Roof Jericho, NY
Jericho’s split-levels and colonials with architectural-review compliance are often best served by stone-coated steel — looks identical to premium asphalt, lasts 60 years, and passes every Oyster Bay Town design-review board we’ve worked with.
Metal Roof Lloyd Harbor, NY
Lloyd Harbor’s waterfront homes sit directly in the salt-air zone. Aluminum standing seam is essentially mandatory here — galvalume steel will show early corrosion within 8-12 years this close to the Sound.
Metal Roof Manorhaven, NY
Manorhaven’s compact North Shore lots benefit from metal roofs’ lower weight — many homes here have original 1940s-50s rafter spans that can’t easily handle the weight of a double-layer asphalt tear-off.
We also install metal roofs throughout Nassau County (North Hempstead, Valley Stream, Elmont) and Suffolk County, including direct neighbors of the towns above. If you don’t see your town listed, call us — we serve all 135 Long Island municipalities on metal and asphalt alike.

Most metal roofing quotes you’ll see on Long Island break down the cost per square foot of roof surface (not home footprint). A typical 2,400 sq ft Long Island colonial has about 2,600-2,800 sq ft of actual roof area once pitch and overhang are factored in. Here’s what each line item really contributes, so you can read any quote you’re given line-by-line.
| Line Item | Typical $/sq ft | Notes (Long Island) |
|---|---|---|
| Tear-off (single asphalt layer) | $1.20 – $2.00 | Includes $800-$1,500 dumpster + disposal fee |
| Deck inspection + repair | $0.50 – $3.00 | Higher on 1940s-60s homes with OSB or narrow-gauge boards |
| High-temp ice & water shield | $0.60 – $1.00 | Mandatory under metal in NY; full coverage recommended |
| Synthetic underlayment | $0.30 – $0.70 | Required on every metal install (Felt is not code-compliant) |
| Metal panels (material only) | $3.50 – $10.00 | Aluminum vs. galvalume steel vs. stone-coated affect range |
| Installation labor | $4.00 – $7.50 | LI labor runs 15-25% above national averages |
| Trim, flashing, ridge cap | $0.80 – $1.50 | Custom-bent aluminum for coastal homes |
| Permit + dump fees | $0.10 – $0.30 | $150-$500 permit + $800-$1,500 disposal |
| Total installed | $11 – $22 / sq ft | Mid-range standing seam: $12-$18/sq ft |
Any quote significantly below $11/sq ft on Long Island means something is being skipped — usually the ice & water shield, the proper underlayment, a pulled permit, or a genuine manufacturer-certified panel. Quotes above $22/sq ft on a standard colonial typically indicate premium copper or zinc systems, which we install on historic North Shore estates but aren’t necessary for most homeowners.
Metal roofs produce three distinct savings streams — and we quantify each on every Long Island estimate so you can see the real lifetime math, not marketing numbers. Based on data from 150+ completed installs and published ENERGY STAR performance figures:
Cooling savings
10–25%
ENERGY STAR reflective metal roofs reflect 30-70% of solar radiation vs. 5-25% for asphalt. LI average: $190-$380 lower cooling cost per summer.
Insurance discount
10–25%
Most NY carriers offer wind-premium discounts on UL 580-rated metal roofs. Typical annual savings: $180-$420 on a standard LI policy.
Avoided replacement
1-2 roofs
Over a 50-year ownership window, asphalt is replaced 2-3x. One metal roof = one install. Avoided cost: $20K-$40K per home in 2026 dollars.
Metal roofs that use ENERGY STAR-qualified reflective finishes also qualify for the Federal Energy Efficient Home Improvement Credit, worth up to $1,200 per year at tax time. That credit alone typically offsets the permit + dumpster portion of the project. Combined, these three streams routinely move metal’s break-even point forward by 2-4 years vs. the sticker-price comparison most homeowners do up front.
Every Long Island metal roof install requires a building permit — pulled by the licensed HIC contractor, not by the homeowner. We handle this on every job. Key code considerations:
Nassau County (3 Town Jurisdictions)
Permits issued by Town of Hempstead, Town of North Hempstead, or Town of Oyster Bay — not the village. Permit fees $200-$500. HIC fingerprint card required on every contractor. Wind-zone design-pressure calculation mandatory on new roofs.
Suffolk County (10 Town Jurisdictions)
Each of the 10 Suffolk towns (Huntington, Smithtown, Islip, Brookhaven, etc.) runs its own building department. Permit fees $150-$450. HIC license + passing the 25-question Suffolk exam required. High-velocity hurricane zone (HVHZ) provisions apply south of Sunrise Highway.
All our metal installs meet or exceed the NY State residential building code, IBC 2018/2020 adoption, and the ASTM E1592 / ASTM E1680 standards for metal panel uplift and air leakage. When the final inspector shows up, our paperwork is already on file.
The best way to understand how metal performs on Long Island is to look at installs we’ve completed and maintained over the past decade. In our experience serving Nassau and Suffolk homeowners since 2011, we’ve followed 40+ metal roofs past the 8-year mark — long enough to see how they hold up against salt, storms, and time.
Oyster Bay waterfront colonial · Install 2014
24-gauge aluminum standing seam installed over a full tear-off. 12 years later, paint finish still reads as install-day condition. Zero corrosion despite sitting within 400 feet of open salt water. Homeowner reported zero leak events through three major nor’easters (including the December 2022 storm) and a 14% reduction in summer cooling bills vs. the previous asphalt roof.
Melville split-level · Install 2016
Stone-coated steel installed over an existing single layer of asphalt. Chose stone-coated for the neighborhood aesthetic. After 9 years, stone granule retention is visually 99%+. Homeowner’s insurance carrier offered an 18% wind-premium discount at first renewal post-install, paying back the premium-over-asphalt in roughly 11 years.
Dix Hills 1970s colonial retrofit · Install 2018
Aluminum shingle installed over existing asphalt to preserve perfectly sound decking. Saved the homeowner $6,800 in tear-off cost. 7 years later, no sagging, no fastener pops, no corrosion. Cooling bills dropped ~19% year-over-year, tracked via the homeowner’s PSEG Long Island account.
Lloyd Harbor waterfront estate · Install 2019
22-gauge zinc-aluminum standing seam on a complex 14-pitch North Shore estate. Custom-bent drip edge and ridge cap. 6 years in, the roof has passed through Tropical Storm Henri and Hurricane Ida remnants with zero damage; the asphalt shingle roofs on two adjacent estates lost shingles in the same events.
What these installs have in common: every single one was pulled as a permitted project, installed with high-temp ice & water shield over the full deck (not just the eaves), and fastened to manufacturer spec. Metal roofs fail when short-cuts get taken on those three items — not from the metal itself.
