Roof ventilation may help control moisture in winter and remove heat from the attic, in the summer, and may also be useful in strategies involving convective stack ventilation (in hot climates) or to avoid ice dams, in cold climates.
Anyway, alone, roof ventilation will not solve thermal problems in the living space below the attic (see Box). And it all depends largely on climate and home design issues.
This page presents the various types of attic ventilation systems, including soffit and ridge vents, gable vents, roof-louver vents, and attic fans, along with their effectiveness.
