How Ridge
Roof Ventilation Works
The Wright brothers used an amazing natural method
to allow heavy objects to defy gravity. Scientists
refer to it as the Bernoulli's
Principle. It is based on negative
air-flow. Ridge roof
ventilation works using the same basic principle.
 An
external baffle creates low pressure over the vent
to "pull" air from the attic.
This is the most
attractive and efficient ventilation device. Its low
profile design minimizes its appearance on the roof,
while its external baffle provides maximum air flow.
It is installed along the ridge of the roof beneath
the ridge shingles. This type of ridge vent creates
the greatest air flow in all wind conditions by
creating a negative air pressure that effectively
pumps air from the attic. |

Energy Free
Roof Ventilation
New air moves throughout the
attic, over the entire length of the attic. Trapped
heat and moisture are then released to
give your roof and attic the relief needed to
properly function.
50/50
The 50/50 rule receives optimum
roof ventilation using the ridge ventilation system:
50% of the intake air-flow starts at the
soffit vent
area and the other 50% is expelled at the ridge area.
It is crucial that
the soffit vents are free of any debris or
attic insulation. Contact
