“Your roof is responsible for taking the damage from everything that the elements can throw at it which include wind, rain, sun and snow but it is additionally attacked by leaves, insects as well as other natural predators. Inefficient roofing often means that these factors find their way into your attic and finally your house and it is important you do what you can to avoid this from happening.”
A well maintained roof a source of pride for a family. It lives longer and gives no trouble to the members living inside the building.

Precisely what does a roofing ventilation system do? It creates cross-ventilation by making sure there is enough air coming in and going out. This results in a bearable roof temperature, along with protects the roof construction materials from getting hot.
The idea behind roof ventilation is essentially temperature control. In a cold climate, it will help to prevent ice dams by preserving a cool roof temperature as well as permits moisture to get out from conditioned living spaces through the attic. On the other hand, in hot climates, proper ventilation enables solar-heated hot air from the attic to escape thus reducing a building’s cooling load and limiting strain on air-conditioning systems. Roof ventilation can even serve both roles in regions where climates range from hot to cold.
The size, shape and materials utilized in building the roof in the first place will govern which ventilation system is right for you. A ventilation system makes use of vents and hoses in the roof to make a balance in the flow of air both under as well as over the roof. Roughly one square foot of venting per 250-300 cubic feet of air in the area just under the roof is required to ensure that the air is balanced.
As you can tell, roof ventilation systems are varied and complicated, so it is always best to work with a skilled roofing company when it comes to which system is ideal for your home. Your contractor can tell you which systems would be best in your climate as well as for your type of roof.
