So what constitutes a good roofing system? A good roof ventilation system ensures that there is balance between the air coming in and the air going out. The cross ventilation of air around the roof keeps the roof temperature bearable and also keeps the material used in the construction of the roof from reaching very high temperatures.

What constitutes a proper ventilation system? Actually the ventilation system for all structure is based on the principle of a wind funnel. A proper roofing ventilation system will consist of an air intake hose and a corresponding exhaust hose to ensure there is proper ventilation of air within and under the roof. The passage of external air around the roof will act like a cooler and ensure the internal temperature will not rise to a temperature greater than that of the air outside. The system is akin to the fireplace we have at homes. The warm air rises and creates a slight suction near the mouth of the intake hose. The relatively cooler air outside the hose removes excess heat from the underside of the sheeting as it exits the exhaust.

The choice of a ventilation system will depend upon the size, shape and the material used in constructing the roof.

This also translates to an appropriate number of vents within the roof. These vents range from static open units and turbine style ones to thermostatically operated and electronic ones. The choice depends upon how deep your pockets are and the size of the roof.

It is always advised to have an expert look at the roofing structure and then suggest the ventilation system. Ideally the ventilation system is designed at the time the roof is constructed. However, with time, certain blockages and other external factors tend to dislodge the ventilation system. This requires for a re-check and re-calibration of the roof venting system.
