Why roofs fail

Ask anyone who repairs roofs where they leak and the answer is the same: not in the middle, but wherever the roof meets something else — or in the layer nobody can see.

A roof here rarely fails where you can see it. It fails underneath, and at the metal. Six places a roof gives way. Five of them are transitions.
Garage Point 1 — ridge caps 1 Ridge caps — full sun, no shade, ever Point 2 — the field of the roof 2 The field — shingle, or tile on felt Point 3 — valleys 3 Two slopes drain through one line, every afternoon Point 4 — flashing 4 Flashing — the metal salt air finds long before the shingle Point 5 — vent boot 5 Vent boot Point 6 — eaves and ice dams 6 Eaves — where the Florida room ties in

The six

What this county does to a roof

Whole neighbourhoods built with genuinely flat, gravel-surfaced roofs. Barrel and concrete tile whose membrane retires decades before the shell. Salt air threading the canals into the eastern cities and finishing the metal first. Black algae feeding on shaded slopes. Boom-era attics ventilated to the minimum of their day. And in the green towns, canopy that sheds into the valleys twelve months a year. Most of what ends a roof here traces back to one of those.
