Why Ventilate?



Lower Cooling Cost

Removes Moisture From Attic

Prevents Mold & Mildew


Proper ventilation is required to protect your home.


A roof turbine "whirlybird" is a ventilating device that uses the power of the wind to remove moisture and HOT air from your attic. 


In the winter months up to 3 gallons of condensed moisture can accumulate in your attic causing a damp environment which may cause mold and mildew on walls and ceilings.


Having adequate ventilation will prevent all these problems associated with heat and moisture in your home.
