Full roof replacement (tear-off) in the Hamptons
A full tear-off and replacement on Long Island in 2026 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. For a 2,500–4,000 sq ft Hamptons roof that puts asphalt at roughly $13,250–31,800 and cedar or metal well into five figures. Hamptons jobs tend to sit at the top of these ranges because of access, complexity and material grade.

What's included
Everything comes off down to the deck: old covering, underlayment, flashing. The roofer inspects and replaces bad decking, installs ice-and-water shield at eaves, valleys and penetrations (full coverage is common on exposed sites), new underlayment, new flashing and drip edge, the roof covering itself, ridge venting and caps, and hauls away the debris. A real quote lists each of those by name.
What it costs in the Hamptons (2026)
Per square (100 sq ft), installed, tear-off included. Long Island ranges unless marked national:
| Material | Per square | Typical life |
|---|---|---|
| Architectural asphalt | $530–795 | 20–30 yrs |
| Designer asphalt (national) | $800–1,200 (to $1,600) | 25–40 yrs |
| Cedar shake / shingle | $900–1,620; premium hand-split $1,600–2,800 | 20–40 yrs |
| Standing seam metal (steel/aluminum) | $1,050–1,785 | 40–70+ yrs |
| Synthetic slate | $1,155–1,890 | 40–50+ yrs |
| Natural slate (national) | $2,000–3,500 | 75–200 yrs |
| Copper standing seam (national) | $2,000–5,000 | 70–100+ yrs |
| Flat membrane, EPDM/TPO | $748–1,265 | 20–30 yrs |
A 2,500–4,000 sq ft roof is 25–40 squares. Multiply and you have the honest range before extras: decking repairs, ice-and-water shield on the whole roof ($4.00–5.50 per sq ft installed), chimney and skylight flashing, and steep-slope or difficult-access labor.
How the job goes
- Roof measurement and inspection; written scope with material, underlayment and flashing spelled out
- Permit, where the job goes to the sheathing (most tear-offs). Village of East Hampton permits usually take 2–4 weeks; the Town of East Hampton has been reporting a 16–20 week backlog; the Town of Southampton is generally faster
- Material lead time (cedar and slate longer than asphalt)
- Install: asphalt 1–3 days, cedar 3–6 days, slate 6–10 days, plus weather
- Final inspection and paperwork for the warranty
Local considerations
Exposure decides the details. Oceanfront and open-field sites (Montauk, Sagaponack, the ocean lanes in East Hampton and Southampton) want full ice-and-water coverage, stainless or copper fasteners and flashing, and a covering rated for wind. Wooded inland lots care more about ventilation and moss resistance. In the villages, the visible material may be subject to design review; in the Sag Harbor historic district it needs a Certificate of Appropriateness.
Overlay vs tear-off
An overlay (a second layer over the old one) is 20–40% cheaper but lasts 15–20 years instead of 25–30, and New York's residential code does not allow it over two existing layers, over slate or tile, or on a wet or rotted deck. See the re-roof page.

Read the full answer →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 I need a permit for a roof replacement in East Hampton?
Usually yes for a tear-off. Across Suffolk County the pattern is that a replacement that goes down to the sheathing needs a building permit, while a shingle-over-shingle recover often does not. In the Village of East Hampton permits typically take 2–4 weeks when the application is complete; the Town of East Hampton (Springs, Wainscott, Amagansett, Montauk, Northwest) has reported a backlog of 16–20 weeks against a statutory 15-day clock. In the village's four historic districts, a visible change of roof material also needs a Certificate of Appropriateness; a new wood-shingle roof is exempt. Confirm with the building department before ordering material.
Read the full answer →When should I replace my Hamptons roof?
By age and evidence together. Architectural asphalt is usually done at 20–30 years, cedar at 20–40, EPDM or TPO at 20–30, standing seam at 40–70+, slate rarely (hard slate 75–200 years; restore it instead). Replace sooner if you see widespread curling or cupping, granules or shakes in the gutters, daylight in the attic, repeated leaks at different spots, or a second layer already on the roof. Insurers also start asking questions at 15–20 years, and some will not renew without an inspection or replacement.
