Before: The roof dryer-exhaust outlet had thick lint deposits around the opening and damper area. We also documented the stacked dryer and its transition connection. Process: We accessed the roof termination with the cleaning air line and removed accumulated lint from the outlet and exhaust path. After: The comparison photos show a more exposed outlet opening and the lint removed during service. We documented the dryer lint passage and transition connection as part of the service. Existing metal discoloration is separate from the removed lint.
