A well maintained roof a source of pride for a family. It lives longer and provides little difficulty to the members living inside the building. A roof is also the structure within a building which is subjected to the utmost extent to natural elements like winds, snow, hail and sunlight.

Exactly what does a roofing ventilation system do? It creates cross-ventilation by ensuring there is enough air coming in and going out. This leads to a bearable roof temperature, in addition to protects the roof construction materials from getting hot.

The idea behind roof ventilation is actually temperature control. In a cold climate, it will help to prevent ice dams by maintaining a cool roof temperature and also enables moisture to get out from conditioned areas through the attic. On the other hand, in hot climates, proper ventilation allows for solar-heated hot air from the attic to get out therefore decreasing a building’s cooling load and limiting strain on air-conditioning systems. Roof ventilation can also serve both roles in regions in which climates range from hot to cold.

The choice of a ventilation system depends upon the size, shape and the materials used in making the roof. Proper ventilation systems consist of vents and hoses in the roof in a way that there’s balanced air flow under and over the roof. It is estimated that in a balanced air ventilation system for a roof, there is a dependence on one square foot of venting for each 250 to 300 cubic foot of air in the attic or the space immediately below the roof. And also this means an appropriate number of vents within the roof.

As you can tell, roof ventilation systems are varied and complicated, therefore it is best to work with a qualified roofer when thinking about which system is suitable for your house. Your contractor can tell you which systems would be best in your climate and even for your type of roof.
