Florida rules
Does Florida's building code allow salvaged or look-alike tile?
Yes, in set conditions. Used tile must be like kind and approved by the building official.
The Florida Building Code, Existing Building, covers repairs to old roofs. As quoted in a Florida Building Commission staff analysis, Section 706.5 allows existing or salvaged slate, clay or concrete tile for reuse to repair an existing tile roof. The salvaged tile must be like kind in both material and profile. Damaged, cracked or broken tile may not be reused. The FRSA brief points to the same section.
The Commission also answered a petition about used concrete tile from a scrap yard. For the 2017 code, staff said used tile that meets the requirements for new materials may be used for repairs, subject to the building official's approval. A Building Officials Association of Florida interpretation from 2019 agrees. It says a repair under the 25 percent limit may use like tile salvaged from another roof.
The 25 percent rule is a separate limit. The version FRSA quotes says no more than 25 percent of a roof or roof section may be repaired, replaced or recovered in a 12-month period unless the whole roofing system or section is brought up to code. There is an exception for roofs built or replaced under the 2007 code or later. Work needed to tie a repair into the old roof does not count toward the 25 percent. Our guide to the 25 percent rule explains it in full.
Code editions change. The 2026 Ninth Edition takes effect December 31, 2026, and FRSA reports that the Florida High Wind tile manual has no changes to its tables or content in this cycle. Your county building department decides what it accepts, so ask it before using salvaged tile.
