Start with conditions, not a product
Discoloration on rafters or decking is a symptom, not the diagnosis. Before anything gets touched, the actual moisture path — a roof leak, poor ventilation, or trapped condensation — needs to be identified.
Build a complete scope
- The moisture source, established before cleaning is priced
- Whether air conditioning and humidity rather than a leak are driving it
- How block walls change what containment and removal actually involve
- The line between material removed and material cleaned, explained
- Verification and the humidity control that keeps it from returning
Clearwater context
Attics here absorb Gulf-side heat most of the year, and older Harbor Oaks-era homes sometimes still have the original, undersized ventilation that current code no longer allows. Salt-heavy air pulled through soffit vents keeps humidity elevated even on otherwise dry days.
