Roof Fans
Installation or Repair - Northern Virginia, VA
One of the kindest things you can do for your home is to ensure it has adequate ventilation in the attic. There are two main reasons for this. The first is it saves on the amount of energy output needed for heating and cooling. The second is to extend the life of your roof which has the task of protecting everything beneath it.
Did you know it is common for the temperature in your attic to get as high as 170 degrees on the summer in Northern Virginia? This puts an enormous strain on your air conditioning system if all that hot air has no way to escape. Most homes can be equipped with vents to help draw it out, but you can be sure there is relief from the heat in the attic with the addition of roof fans.
The amount of money you save on your energy bills is significant compared with the cost to install roof fans. An electric fan uses very low energy and you can save even more by using a solar powered model. Older homes were built without enough air circulation in the attic. Newer homes have more vents but often these do not allow sufficient air flow. Roofs fans make a perceptible difference even if the attic has several vents.
The attic is one of the spaces in the house where flammable materials such as books, old photographs and papers are stored. In an overheated attic these things become a fire hazard. You also need to consider the stress on your respiratory and circulatory system to be in the kind of heat, even for a few minutes. If the vents are not removing the heat, your attic is a good candidate for electric or solar roof fans.
It may sound strange to you, but in the winter the attic temperature needs to be maintained at a temperature not much higher than the exterior air temperature. Much warmer than this and it will cause snow to melt where it contacts the roof. The end result is the formation of ice dams and water backing up under the shingles. Roof fans are just as important in freezing weather as they are in the summer.
