Everything You Need to Know About Roof Ventilation

You might improve the energy efficiency of your home in several ways. Roof ventilation (also called attic ventilation) is a popular method for lowering energy bills, and this practice also has other benefits to offer. It can even increase the longevity of your roof. When done properly, vents are installed to allow cold air to circulate. This steady volume of air flow can serve a few very important purposes.

What Attic Ventilation Does for Your Home 

By ensuring that your roof is adequately ventilated, you may accomplish multiple objectives. The following are the primary benefits of proper attic ventilation:

• Minimize Accumulation of Moisture: An attic that is well ventilated will help to limit the amount of moisture that accumulates indoors. If you do not have vents installed, the moist air will rise and permeate the underside of the roof. This condensation can wreak havoc with the roof as a result. By reducing the moisture buildup, roof ventilation may stop mildew and rot from destroying the framing and sheathing of the roof.
• Prevent Ice Dams from Forming: Roof ventilation enables a natural flow of outdoor air to circulate through the top of the attic. While it may seem counter-intuitive to ventilate frigid air in the wintertime, this air should not reach into your living space. Instead, it will help to prevent ice dams from forming on the roof. Ice dams occur when the warm air from an unventilated attic causes snow to melt off the roof. Then, the liquid freezes again in the gutters, resulting in ice dams. This damming may lead to much roof damage.
• Increase Energy Efficiency: In the summertime, sufficient attic ventilation will complement your air conditioning system. It will reduce the amount of heat that builds up near the top of your home. This means that your air conditioner will not need to work as hard to keep your home temperate.
• Lengthen the Life of Shingles: Excessive heat in the attic may have a negative impact on roof shingles. As the heat rises with no other place to go, it heats the shingles and ages them prematurely. Ventilation will stop this process. Consequently, roof ventilation is often a requirement in warranties for asphalt shingles. 


Maintain Your Roof with Attic Ventilation
If your roof is made of shingles, you should take steps to ensure that it stays well ventilated. Doing so could significantly increase the longevity of your roof. Even if you do not have a shingled roof, attic ventilation may prevent the growth of mildew and the formation of ice dams. Roof ventilation could also improve the energy efficiency of your home.
