Roof Ventilation
The primary purpose for the installation and use of both roof and attic ventilation is to allow heat and humidity to escape the roof area. The roof area collect a considerable amount of sun and become heated, in turn heating the air which becomes trapped underneath the roof, the attic. As well, heat and condensation rising from within the house structure can become trapped in the attic area underneath the roof surface, causing a heat and or moisture build-up.
To prevent a build-up of heat and moisture from occurring, roof vents are used.
