A standing seam metal roof is the last roof most homes on Long Island will ever need: 50–70 years of service, no granules to shed, wind ratings well past anything a shingle carries, and a finish that looks the same in year 30 as year one. It costs roughly twice what asphalt does up front and about half as much per year of service.
Shoreline Roofing Co installs standing seam and exposed-fastener metal systems — panels roll-formed to the exact length of each roof plane, concealed clips that let the metal expand and contract, high-temperature underlayment, and trim details that keep water out at every edge. This is not a shingle crew that occasionally does metal; standing seam is a trade of its own.
💲 What does metal roofing cost on Long Island? See the full 2026 cost guide →Mechanically seamed or snap-lock panels with no exposed screws on the field of the roof. Nothing to back out, nothing to re-seal in year 12.
Panels are formed to the run of each roof plane — no horizontal laps, no seams mid-slope where leaks start.
Factory-baked finishes with 30–40 year fade and chalk warranties. Dozens of colors, from charcoal and bronze to standing-seam classic galvanized look.
Clip spacing and gauge specified to the uplift and snow loads of your site, with snow guards where the roof sheds onto walkways and entries.
From the Hamptons and Montauk through the North Fork and along both shores, salt air will find the cut edges of a steel panel. We specify aluminum standing seam in coastal exposure — it does not rust, ever — with stainless fasteners and a PVDF finish rated for marine environments.
South Shore and East End homes see sustained coastal wind that shingles are not built for. Clip spacing and seam engagement on a standing seam system are specified to the uplift rating your site needs, not a default.
Standing seam in charcoal, bronze, or matte black sits naturally on Hamptons shingle-style and North Shore colonial homes. We help with color and seam-height choices where architectural review boards are involved.

Standing seam steel or aluminum with a PVDF finish is rated for 50 years and routinely goes longer. The finish warranty typically runs 30–40 years; the panels outlast it.
Not over a solid deck with underlayment and attic insulation — the setup on every residential install. The tin-roof-on-a-barn sound comes from open-purlin construction, not homes.
Metal goes on the same deck asphalt does. We strip the old roof, repair any soft plywood, and install over a full underlayment. Overlays are possible in some cases but we recommend a tear-off so the deck is verified.
Metal recovers a high share of its cost at resale and lowers insurance premiums with some carriers because of its Class A fire and high wind ratings — worth a call to your agent.
