Standing seam metal and copper roofing in the Hamptons

Standing seam metal runs about $1,050–1,785 per square installed on Long Island in 2026 (steel $1,000–1,600 and aluminum $1,100–1,800 nationally), and copper $2,000–5,000 per square with whole-roof projects from roughly $22,500 to $135,000 by size and complexity. Steel and aluminum last 40–70+ years, copper 70–100+. Near the ocean, aluminum and copper resist salt corrosion far better than steel, which is why they dominate on Montauk and Sagaponack roofs and on the East End's estate houses.

What's included

Tear-off or new deck, high-temperature underlayment, clips and panels formed to the roof (site-formed or factory), concealed fasteners, matching flashing and trim, snow guards where needed, and copper or aluminum gutters to match. Porches, bay windows and dormers are common partial-roof jobs; whole-house standing seam is increasingly common on modern and farmhouse-style new builds.

What it costs in the Hamptons (2026)

  • Standing seam, Long Island blended: $1,050–1,785 per square
  • Steel $1,000–1,600; aluminum $1,100–1,800 (national)
  • Copper: $2,000–5,000 per square; projects $22,500–135,000 depending on size and complexity (national)

How long it lasts

  • Steel and aluminum standing seam: 40–70+ years
  • Copper: 70–100+ years, and it weathers to the green-brown patina you see on East End estate houses

Steel, aluminum or copper

Steel is the cheapest and the weakest against salt. Aluminum does not rust and costs a little more. Copper costs two to three times as much, lasts longest, needs no coating, and is the traditional choice for bays, porches and dormers on the Hamptons' older houses. On oceanfront and bayfront sites we recommend against bare steel.

Local considerations

Metal sheds snow and ice well, which matters on the wooded inland lots where ice dams form. On the ocean it is the material that shrugs off wind best once the clips and seams are done right. In the villages and the Sag Harbor historic district, a standing seam roof on a visible slope may need design review; copper on a bay window or porch is often accepted as traditional, a full standing seam main roof less so.

FAQ

Common questions

What's the best roof for a beachfront Hamptons home?

There is no single answer, but there is a short list. Standing seam in aluminum or copper handles wind best and shrugs off salt (40–70+ years for aluminum, 70–100+ for copper). Natural slate lasts 75–200 years and resists wind once properly hung, with copper fasteners. Cedar is the traditional choice and works if it is fastened for wind and maintained on schedule, at the short end of its 20–40 years. Architectural and designer asphalt is the budget option, with some designer lines wind-rated to 130 mph. Whatever the covering, the details decide it: full ice-and-water shield, stainless or copper metal.

How much does a roof replacement cost in East Hampton?

In 2026, a full tear-off and replacement on Long Island runs about $530–795 per square (100 sq ft) for architectural asphalt, $900–1,620 for cedar, $1,050–1,785 for standing seam metal and $1,155–1,890 for synthetic slate; natural slate is $2,000–3,500 per square nationally. A typical 2,500–4,000 sq ft East Hampton roof is 25–40 squares, so asphalt lands around $13,250–31,800 and cedar or metal well above that. East Hampton jobs tend to sit at the top of the ranges because of access, roof complexity and material grade.

How long does a Hamptons roof replacement take?

The work itself is quick: asphalt 1–3 days (one day for a simple roof, two or three for a complex one), cedar 3–6 days, slate 6–10 days, plus weather. The calendar is dominated by what comes before: a permit (2–4 weeks in the Village of East Hampton; a reported 16–20 week backlog in the Town of East Hampton; the Town of Southampton is generally faster), design review in the villages' historic districts, and material lead time, which is longest for cedar, slate and copper. Book a spring roof in winter.

Do roofers need a license in Suffolk County?

Yes. Roofing contractors doing residential work in Suffolk County must hold a Home Improvement Contractor license from the Suffolk County Department of Labor, Licensing & Consumer Affairs, and some towns and villages on the East End layer their own registration on top. Ask for the Suffolk license number and a current certificate of insurance (liability and workers' compensation) before anyone goes on the roof, and check local references. Every roofer we match holds the county license and carries insurance.
