Whether you are in a place with hot or cold climate, attic ventilation or roof venting is one of the most useful and simple building assemblies you can have in your home for added energy efficiency. It may be just placing insulation on your air sealed attic floor, but it is important to seek the help of professionals or experts to have proper air flow, and avoid mistakes which can cause severe problems like excessive energy loss, molds, ice dams and rotting.
In this article, you will learn about some tips to make sure that you have the right attic ventilation in your home.
Look for signs whether your attic is properly ventilated or not.
● No vents on the roof – If you just moved into a new home, you might not know yet whether your attic needs ventilation. Roof vents may be in the form of a ridge vent along the peak of your roof, or a gable vent at the top of gables.
● A hot ceiling on a sunny day – Try touching the ceiling of your attic on a warm day, and if it is hot, you need proper ventilation.
● Having thick ridges of ice on your eaves during winter – Warm air from inside your home will rise up in the attic and melt the snow which will freeze again and create ice dams on the cold eaves.
● Moisture on rafters or roof sheathing during winter – The warm air from your house may also create moisture, dampness or frost in your attic which you can inspect with the help of a flashlight.
Roof vents are placed near the roof peak, and soffit vents are placed in the eaves.
This is commonly used for best results, though there are different styles of vents. With this, air will flow in through the soffit vents and go out through the roof vents.
Use the right number of vents for the area of your attic.
A square foot of vent opening is usually used for every 150 square feet of attic. Naturally, more ventilation is better but there are some building codes which allow you to reduce this by about half under some conditions.
There are a lot of variations in building practices over the country due to the varying climate, and there is no one rule which fits all. Contact your trusted roofing company today and ensure that you have the right attic ventilation in your home.
