Pittsburgh receives approximately 38 inches of precipitation annually, distributed fairly evenly across all seasons. This consistent moisture input combines with dramatic temperature swings during spring and fall to create prime conditions for attic water intrusion. The Allegheny Plateau's topography funnels weather systems through the region, bringing lake-effect snow from Erie and moisture-laden air masses from the Ohio Valley. When rapid warm-ups follow heavy snow, roof drainage systems become overwhelmed. Ice dams form along eaves where heat escaping through inadequate insulation melts snow above while temperatures below freezing persist at roof edges. Meltwater backs up under shingles, bypassing normal water barriers. Many Pittsburgh homes built during post-war expansion feature shallow roof pitches that exacerbate ice dam formation and reduce natural drainage effectiveness during heavy rain events.
