Regional context, not property-specific evidence. The federal wildfire occurrence database lists 3 fires within 5 miles of Philadelphia between 2008 and 2009, burning about 5 acres in total. None started naturally. None was recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.
