How To Improve Your Attic Ventilation When Getting A New Roof

Posted on: 15 October 2014

When the time comes for you to get a new roof, you may want to talk to the roofers about roof vents. These vents are used to improve the circulation of air inside your attic, and they offer benefits for you as a homeowner. You may want to begin by learning about what roof vents are and the benefits they offer, and you can then ask your roofer to install them for you.

What Are Roof Vents?

Roof vents are small ventilation systems that are designed to let air from the attic escape. There are several types of roof vents, but most roofers recommend using two common types. These are:

  • Ridge vents – ridge vents are located at the highest part of your roof.
  • Soffit vents – these vents are placed inside the soffits of your house.

When a house has roof vents, they allow air from the attic to escape, and they replace the air with fresh air from the outside. The purpose is to:

  • Keep the air fresh inside the attic by removing stagnant air
  • Reduce the amount of moisture inside the attic
  • Keep the attic cooler in the summer and warmer in the winter

Installing roof vents is a requirement when new homes are built, and your roofer will tell you how many you will need.

How Many Are Needed?

According to The Family Handyman, the number of roof vents you need is based on the square footage of your attic. For every 150 square feet of attic space, you should have 1 roof vent. For example, if you have 1,500 square feet of attic space, you may need 10 roof vents. Building code requires only about half this amount, but you may want to stick with the number of vents your roofer suggests.

What Are The Benefits?

Roof vents offer a lot of benefits, but they rely on an attic having the right amount and type of insulation. Insulation is commonly found in attics, but you may want to investigate the insulation your attic has. This is especially important for older homes, and adding more insulation when you replace your roof is a good time to do this.

A combination of attic insulation and roof vents offer the following benefits:

  • Your house will stay a more consistent temperature. During the summer, the purpose of the vents is to keep the attic cooler. In the winter, the purpose is to keep the attic warmer. By doing this, the living space in your home will be warmer in the winter and cooler in the summer.
  • You may save money on energy costs. If the ventilation system works as it should, you may notice a decrease in your energy bills.
  • The shingles on your roof may last longer. One of the reasons shingles wear out is from a buildup of moisture. This moisture is found in the attic ceiling, and the moisture can get into the shingles. This will destroy them, leaving you with a bad roof. Because the vents allow air to circulate, moisture will leave the attic instead of dwelling inside. During the winter, the vents will also help melt snow and ice on the roof, and this too keeps the shingles in better condition.

Roof vents are not hard to install, and installing them while replacing a roof is the best time to do this.

If you are interested in learning more about roof vents, contact a roofer in your area. You can have this done while the roof is replaced, and you will end up with a home that has a great roof and an effective ventilation system.
