South Beach, the bay islands, and the coastal cities next door each put a different roof in the same salt air.
South Beach
South Beach is the Art Deco district and the blocks just inland from it. Hotels and walk-up apartments often hide a flat roof behind a parapet. Houses a few streets west still carry barrel tile. Salt spray reaches both, and the sun sits on the parapet walls all afternoon.
Mid-Beach
Mid-Beach is the taller condominium coast along Collins Avenue. Most of those buildings have flat roofs, roof decks, and a crowd of vents, rails, and equipment curbs. Wind off the Atlantic loads the edges, and salt air works on every exposed fastener.
North Beach
North Beach mixes mid-rise condos with smaller houses. Tile shows up again on the houses. The same salt air is here, with a little more room between buildings and a little less of the hotel parapet.
Fisher Island
Fisher Island sits in the water on more than one side. Roofs here live in salt air, and the boat traffic does not change what the fasteners have to survive. Tile and flat roofs both show up.
Star Island
Star Island houses face the bay. Barrel tile is common. The metal that matters is the flashing, the drip edge, and the nails or screws holding the tile. Those pieces rust long before the clay does.
Venetian Islands
The Venetian Islands are a string of bay islands with houses close to the water. Tile roofs, stucco walls, and short metal flashings at the eaves are the usual picture. Afternoon rain runs hard toward the bay side.
Sunset Islands
Sunset Islands is another bay-house neighborhood. Roofs are mostly tile. Trees and neighboring walls change how wind hits a slope, so one house can lose a ridge while the next one looks calm.
Bal Harbour
Bal Harbour has high-rises near the inlet and houses set back from them. Flat roofs on the towers need drains that keep up with a summer storm. Houses nearby still use tile. Salt air is part of both.
La Gorce and the islands nearby
La Gorce, Normandy Isles, Surfside, and Bay Harbor Islands sit on the same coast. Condos, small hotels, and houses share the wind and the salt. Each building has its own roof, and the office for this company remains the Miami address.
