Mold found in the
attic.

The most common causes in Florida: (1) Roof penetration leaks — around vents, skylights, or at flashing — that introduce moisture to attic framing and sheathing; (2) Inadequate attic ventilation — Florida's heat causes moisture to condense on cooler surfaces without proper air flow through soffit and ridge vents; (3) Bathroom or kitchen exhaust fans venting into the attic instead of out through the roof — a code violation that introduces warm, moist air directly into the attic space; (4) AC refrigerant lines in the attic that sweat condensation onto nearby wood; (5) Ice dam-like effects from temperature differentials between the cooled living space and hot attic. The moisture source must be corrected before or during remediation, or the mold returns.

Coverage depends on the moisture source. If the attic mold resulted from a covered sudden loss — a roof breach during a storm, a burst pipe that ran into the attic — most Florida HO-3 policies cover remediation. If the mold developed from inadequate ventilation, gradual roof wear, or long-term condensation (chronic moisture), it's typically excluded as a maintenance issue. A licensed mold remediator documents the moisture source, which becomes the key evidence for your adjuster. Undiscovered storm damage that caused attic mold is sometimes covered retroactively when properly documented.

Attic mold typically affects: roof sheathing (OSB or plywood panels between rafters and roofing material); rafters and structural framing; attic insulation (fiberglass batts or blown insulation that holds moisture); and any stored items in the attic. In Florida, mold also grows on the paper facing of fiberglass insulation batts. OSB sheathing is particularly susceptible — it absorbs moisture readily and degrades faster than plywood. Contaminated insulation must be removed and replaced; framing and sheathing can sometimes be treated in place if the mold is surface-level and the structure is sound.

Attic mold remediation in Florida typically ranges from $1,500–$15,000+ depending on: attic size (square footage affected), whether insulation must be removed and replaced ($1,000–$4,000 for full removal and replacement), whether sheathing requires replacement (adds $2,000–$8,000 for severe cases), and whether the moisture source requires repair. A small isolated area (one rafter bay, limited sheathing) runs $1,500–$3,000. A full attic contamination with insulation replacement runs $6,000–$15,000+. Get a licensed mold remediator to assess — scope varies significantly by attic configuration.

Florida Statute 468.8411 requires a DBPR-issued Mold Remediator license to perform mold remediation. A roofing contractor who finds mold in your attic cannot legally remediate it — they can repair the roof leak, but the mold must be handled by a licensed mold remediator. CFDR's license is MRSR5370. The sequence is: licensed mold remediator assesses and quotes → roofer repairs the leak (moisture source) → licensed mold remediator performs remediation and oversees clearance testing → roofer or contractor replaces any removed insulation or sheathing after clearance.
