Hurricane Isaias damage guides, Florida

Fired Ludowici clay and quarried slate both outlive the crews that install them — a century is the floor, not the ceiling. What fails first is everything underneath: the underlayment, the flashing, the fasteners. Get the hidden work right and the stone does its hundred years without complaint.

Yes. The match starts from Ludowici's own catalog and graded salvage. Every profile Ludowici ever fired lives in a catalog, and a 1920s field deserves its exact match — not the closest thing on a pallet this month. Salvage comes off graded and re-laid where it shows; new fired clay is blended through the field so the repair disappears instead of announcing itself.

Both, and repair comes first. A slate roof almost never fails as stone — it fails at the details. Rusted steel nails, headlap shaved thin, a valley re-flashed in something cheap. Most “failed” slate roofs need their fasteners, flashing, and headlap corrected, not a tear-off. Full replacement is the last resort, never the opening bid.

On mid-century buildings, often yes — transite and older membranes have to come off under negative air, with certified crews and a clean manifest, before a single new course goes on. It is the dangerous work nobody photographs, and it is handled by the book or not at all.
