Start with conditions, not a product
Discoloration on decking or rafters is a symptom, not a diagnosis. Before touching anything, the actual cause — a roof leak, poor ventilation, or built-up condensation — needs to be pinned down first.
Build a complete scope
- The moisture source, identified and documented before cleaning is priced
- Whether year-round humidity or a discrete leak is driving it
- Sealing the area off and managing airflow for the duration
- What is removed versus cleaned, and the basis for drawing that line
- Verification afterward, plus the humidity control that prevents a repeat
Lakeland context
Attics in Lakeland's older bungalow stock often have less ventilation than current code calls for, and mature oak canopy over many older lots keeps roofs shaded and slower to dry after rain. Newer subdivisions further out tend to have better attic ventilation but less shade, trading one problem for another.
