Ocean air and the metal
Broward’s coast is not a line. It is a network. The ocean, the Intracoastal and the canals that thread Fort Lauderdale, Pompano and Hollywood put salt air deeper into the county than a map suggests, and salt is selective: it barely touches the covering, and it steadily destroys everything metal that holds the roof together.
- 1 Ridge caps. The ridge is first to bake, first to lift.
- 2 The field. Barrel tile or shingle, over an underlayment quietly doing the work.
- 3 Valleys. One line carrying what two slopes shed, at the pace this coast rains.
- 4 Flashing. Where salt reaches the metal years ahead of the covering it protects.
- 5 The vent boot. A rubber collar that hardens, cracks, and lets the rain straight in.
- 6 Eaves. Where the screen enclosure meets the roof, and where fasteners give up.
The order of failure
Fasteners go first: the thinnest metal on the roof, and the least visible. Then vent collars and pipe boots, corroding at the base while the sun cracks the rubber above. Then step flashing at the walls, drip edge at the eaves, gutter hardware last. The pattern repeats across every eastern neighborhood: the roof fails at its junctions and edges while the field in the middle still photographs well, which is exactly why owners doubt the diagnosis until the leak arrives.
The gradient is steep. A few blocks change the exposure meaningfully, and a canal-side address without ocean frontage still lives in the salt. Contractors who work the east side price by address, and they are right to.
Specifying for the address
The answer is material selection, and it is cheap relative to what it protects: aluminum or coated flashing rather than bare galvanized, stainless or coated fasteners, coastal-rated vents. On any replacement east of the highway, the metal should appear in the quote as replaced, itemised and specified, a bid that treats it as incidental has not read the address. Between replacements, the habit that pays is a look at the metal every few years; by the time the covering stains, the metal finished failing long before.
