Flat Roof Ventilation Design

Ventilation is crucial to these areas as they affect the building as a whole both inside and out.

However a call was made on site without our consent sent to install 2 4 strapping for ventilation on our two flat roof bump outs contray to the design. There are two types of flat roof systems warm and cold roofs which affect the positioning of the ventilation.

8 aura vent. It has a very sleek design with a rounded head that rotates to let the hot air out of the attic while bringing in fresh cooler air at the same time. When thermal insulation is placed below the deck the ventilation must also be on the underside. For a more low profile type of flat roof vent the aura vent is the ultimate choice.

Our understanding is that flat roofs in general don t vent as thoroughly as pitched roofs with with the presence of gable vents. Removal of excess heat and moisture will help the life of the roof and will help the functionality and efficiency of the hvac systems. Flat roof ventilation is achieved by creating air changes to the attic or plenum.

Where this has been provided in addition to other normal design requirements there has generally been no problem.
