Start with conditions, not a product
A stained rafter or discolored decking is a symptom, not the diagnosis. Before anything gets touched, the actual moisture path — a roof leak, poor ventilation, or condensation against the underside of the deck — needs to be identified.
Build a complete scope
- The wetting source, established before any remediation is costed
- Whether air conditioning against humid air is condensing inside the wall
- How block construction changes what containment and removal involve
- What is removed and what is cleaned, with the reasoning set out
- Verification, plus the humidity control that stops it returning
West Palm Beach context
Attics under West Palm Beach's barrel-tile and metal roofs run hot most of the year, and the salt-laden onshore breeze keeps soffit-drawn air unusually humid even on clear days. Older homes in the historic districts sometimes have add-on roof sections whose ventilation paths never quite matched later code.
