Comparing condensation with leakage in the attic
Use temperature and trigger timing to separate two moisture mechanisms. This guide adapts the method to roof deck, insulation, ducts and ceiling penetrations.
Documenting a water stain in the attic
Create a useful record of location, edge, timing and triggers before repainting. This guide adapts the method to roof deck, insulation, ducts and ceiling penetrations.
Investigating rain-linked symptoms in the attic
Relate wind, intensity and delay to the building geometry. This guide adapts the method to roof deck, insulation, ducts and ceiling penetrations.
Mapping a musty odor in the attic
Use room boundaries, airflow and timing to narrow an odor pathway. This guide adapts the method to roof deck, insulation, ducts and ceiling penetrations.
Mapping attic frost before thaw erases the evidence
