The rules for a reroof in San Castle
Layers
When the old roof must come off
A tear-off to the deck is required where the roof already has two layers, where the covering is tile, slate or wood shake, or where it is water-soaked or deteriorated (FBC Existing Building 706.3).
The 25 percent rule
Partial work can bring in the whole roof
Florida limits partial work: if more than 25 percent of a roof or roof section is redone in 12 months, the whole roof or section has to meet the current code. Roofs built or replaced under the 2007 Florida Building Code or later are exempt; only the new part must meet the code in effect (FBC Existing Building 706.1.1; Fla. Stat. § 553.844(5)).

Houses permitted before 2002
A secondary water barrier and deck re-nailing
If your site-built single-family home was permitted before the Florida Building Code took effect (March 1, 2002), a full roof replacement must include a secondary water barrier and re-nailing of the roof deck: at least two 8d nails per rafter, a nail counting as 8d if it is at least 0.113 inch thick and 2¼ inches long (Fla. Stat. § 553.844(3); FBC Existing Building 706.7).
