We inspected the dryer exhaust route and documented a roof hood heavily packed with lint. At the roof, an air line was used during service, and a dense piece of removed lint shows the combustible material taken out of the exhaust path. Removing this buildup helps reduce exhaust restriction and combustible accumulation; it does not make a dryer fire-proof. The attic views document the rigid dryer-exhaust pipe and a joint receiving mastic sealing compound. Sealing the connection helps keep exhaust within its intended route rather than escaping through a loose joint. The photographs also show the LG dryer, accessible wall collar and flexible transition hose. A later view of the same roof hood shows substantially less lint at the opening. Later close-ups document the rigid pipe bore, transition-hose interior, wall connection and connected transition. These views tell the initial-condition, service and documented-result story. No measured airflow or drying-time improvement is claimed.
