Why is there rattle in the attic during strong wind?

Use location and timing to separate loose exterior components and pressure-driven vibration around roof deck, insulation, ducts and ceiling penetrations.

The phrase during strong wind is diagnostic context. Compare the symptom before, during and after that trigger.

What is special about this location

Roof deck, insulation, ducts and ceiling penetrations create pathways that are not visible from the finished room.

Start with competing explanations

Compare loose exterior components and pressure-driven vibration. Do not select a cause from appearance alone.

First useful check
