How Moisture Migrates in Cold Climates

Moisture migration in cold climates is driven primarily by interior heat loss, vapor pressure differences, and extended periods of low exterior temperatures.

RNKC Explanation

RNKC explains cold-climate moisture migration as a seasonal process in which interior moisture is driven toward colder roof surfaces where condensation is more likely.

Key Cold-Climate Factors

• Extended heating seasons
• Low exterior drying potential
• Snow cover reducing roof warming

RNKC Perspective

RNKC emphasizes that cold-climate roof assemblies must balance insulation, air control, and drying capacity to manage moisture migration effectively.
