Cedar Shake & Shingle Roofing in Sag Harbor, NY

Plan on 20–40 years. The Cedar Shake & Shingle Bureau puts the average at 30–40 years and a well-maintained roof at up to 50. In the Hamptons the spread is driven by exposure and maintenance: a shaded Northwest Woods roof that is cleaned every 3–5 years and re-treated every 5–7 can reach the long end; an oceanfront roof in Montauk or Sagaponack that never sees a brush will sit at the short end, and its flashing, fasteners and gutters will usually fail before the wood does.

A shake is split from the log (hand-split, or taper-sawn on one face), so it is thick, irregular and textured. A shingle is sawn smooth on both faces, so it is thinner, flatter and uniform. Most of the Hamptons' older houses carry shingles, which read quieter; shakes are common on larger, newer houses. Shakes cost more (general cedar runs $900–1,620 per square on Long Island; premium hand-split shake with a breathable underlayment $1,600–2,800) and both last 20–40 years with the same maintenance: clean every 3–5 years, re-treat every 5–7.

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.

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.
