Roof ventilation allows air from the outside to enter and leave the attic and other ventilation spaces on your roof. This mostly happens through roofing vents that allow the air to flow in and out of the attic. If you don't have ventilation in your roof, it is important to consult a roofing expert to advise you on how you can install ventilation in your roof.

Different Ventilation Methods

When it comes to roof ventilation, there are different methods, which vary from house to house. To determine the best ventilation method for your roof, you need to consult a roofing expert. However, you need to understand the following ventilation methods:

1. Ridge vents and soffit vents - A good ventilation system should provide an entry and exit point. Ridge vents are found along your roof's peak, and they help in releasing moisture and hot air in your attic. Soffit vents, on the other hand, are found in the overhang of a roof. Both the ridge and soffit vents work in harmony when ventilating your home.

2. Attic fans - Also known as whole-house fans, attic fans are mostly installed to remove any warm air in the attic through the roof vents. They significantly assist in cooling your home.

3. Gable vents - These vents are found on each end of a house. Mostly, they are installed on the siding, under the peak of the roof. Gable vents assist air to flow out of the attic while also preventing moisture and snow from entering.

Advantages of Roof Ventilation

Assists In Extending the Lifespan of Your Roof

Roof ventilation plays a great role in preventing the formation of ice dams that can damage your roof. Ice dams happen when the heat from the attic combines with the sun's heat to melt the ice and snow on a warm roof. This forms water that starts to run to the edge of your roof,and then starts to freeze as it drips. When the water and ice begins to build up on the edge of the roof, there is a possibility for it to back up beneath the roofing materials.

This can significantly damage your entire roof, attic, and even the walls on your home. However, roof ventilation assists the warm air in the attic area to escape before it starts to melt the ice and snow on the roof.

Reduces Your Utility Costs

Since roof ventilation assists in removing hot air in the attic, it contributes to cooling your home. When you ventilate your roof, hot air can easily escape the attic, thus reducing the times you need to use your air conditioner. As a result, you end up paying less in energy bills.
