Attic Mold Remediation After Roof Leak — Jacksonville Beach
A hidden roof leak saturated attic insulation and sheathing, triggering widespread Aspergillus/Penicillium growth across 800 sq ft. We contained, removed, and restored clearance in under two weeks.
The Challenge
The homeowners discovered musty odors and dark staining on the attic sheathing only after a roofer flagged a slow leak. Inspection revealed moisture content above 28% in the plywood and visible mold colonies spanning roughly 800 square feet, with spore counts 40x normal background. The HVAC return was drawing attic air, spreading spores into the living space.
Our Approach
We built a 6-mil poly containment under the affected attic bays, set up HEPA-filtered negative air, removed contaminated insulation, and media-blasted the sheathing. Affected framing was treated with an EPA-registered antimicrobial, dried to below 15% moisture, and the roof leak was documented for the insurance claim.
The Outcome
Post-remediation air sampling confirmed spore counts returned to normal background levels with no elevated Aspergillus/Penicillium. The claim was documented and the homeowners re-insulated with clearance paperwork in hand.
