The rules for a reroof in Willow Oak
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)).

Manufactured homes
Say it is a manufactured home
The Florida rules for older site-built houses above apply to “site-built, single-family residential structures” (Fla. Stat. § 553.844(3)); a manufactured home is not one. Tell the person on the line it is a manufactured home.
