Case Study: Roof Deterioration Damage
Overview
A homeowner reported wind-related damage following a recent storm. Our team was retained to inspect the roof covering and surrounding property features to determine whether the reported issues were storm-related and recent, or the result of pre-existing conditions.
Investigation
A comprehensive roof inspection was performed, focusing on the condition of the asphalt shingles, underlying felt, and decking. Observed damage patterns were compared against weather data and historical satellite imagery to evaluate the age and progression of the roof’s condition.
Initial Findings
Observed Damage: Numerous asphalt shingles were torn, uplifted, or missing entirely. In several areas, large patches of shingles were absent, leaving plywood decking exposed.
Material Condition: The felt paper beneath damaged sections was heavily oxidized and coated with debris, indicating long-term exposure. The plywood substrate was also severely weathered from extended sun exposure.
Historical Evidence: Available satellite imagery confirmed that significant roof damage predated the most recent storm event.
Contributing Factors: Poor roof covering performance and/or inadequate attic ventilation likely compromised shingle adhesion, making the roof more susceptible to gradual uplift and deterioration.
Outcome
The investigation determined that neither the washer nor the dryer contributed to the fire. Both units, and the wall receptacle serving them, showed no evidence of involvement. This supported our client—the appliance repair contractor—by confirming that their prior work was unrelated to the ignition sequence.
Lessons
Thoroughly establishing the exact area of origin is essential in fire investigations. By narrowing the investigation to the correct zone, it becomes possible to identify the specific failure—in this case, improper electrical practices—while ruling out unrelated equipment.
