Checking indoor humidity patterns in the roof
Log humidity and temperature through occupancy and weather changes. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Comparing condensation with leakage in the roof
Use temperature and trigger timing to separate two moisture mechanisms. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Documenting a water stain in the roof
Create a useful record of location, edge, timing and triggers before repainting. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Investigating rain-linked symptoms in the roof
Relate wind, intensity and delay to the building geometry. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Mapping a musty odor in the roof
Use room boundaries, airflow and timing to narrow an odor pathway. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Preparing a professional handoff in the roof
Turn observations into a concise timeline with evidence and unanswered questions. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Tracking a crack over time in the roof
Use consistent scale, angle and dates to distinguish stable from changing movement. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
Verifying a repair in the roof
Test the original trigger and record whether the symptom returns. This guide adapts the method to coverings, flashings, penetrations, drainage and wind exposure.
