Roof ventilation is an important part of keeping your home in tip-top shape. A well-ventilated roof helps to prevent moisture build-up, which can lead to all sorts of problems like mold and mildew. Additionally, good air circulation helps to keep your attic cooler in the summer and warmer in the winter, which can save you money on energy bills.
What Happens if You Don’t Vent a Roof?
If you do not vent a roof, it can become damaged over time. This is because the heat and humidity will build up in the attic, which can cause the shingles to deteriorate and the wood to rot.
The purpose of ventilation is to remove this heat and humidity from the attic, so that there is not any unnecessary heat in your attic.
Passive and Active Roof Venting
There are two types of roof ventilation that can be implemented in your attic: passive and active.
Passive ventilation relies on natural forces to move air through the attic. This can be done with vents in the soffit and ridge vent. Active ventilation uses fans to force air through the attic. This is more effective, but it does require more energy to operate.
If you are not sure if your roof is properly ventilated, you should contact a roofing professional to have it inspected. They will be able to tell you if your roof needs more ventilation and can provide guidance on the best way to achieve this.
Types of Roof Vents
There are several types of each passive and active vents that a roof can be equipped with.
Wind Turbines
This type of roof vent is also known as a whirlybird. It is a small, cylindrical vent that is installed on the roof. As the name suggests, it relies on the wind to spin its blades, which in turn creates suction. This suction pulls air out of the attic and helps to keep it cool.
Soffit Vents
Soffit vents are installed in the soffits, which are the spaces between the eaves and the exterior walls of the house. They allow air to enter the attic, which helps to ventilate it.
Ridge Vents
Ridge vents are installed along the ridge line of the roof. They allow hot air to escape from the attic, which helps to keep it cool.
Gable Vents
Gable vents are installed in the gables, which are the triangular spaces at the end of the roof. They allow air to enter and exit the attic, which helps to ventilate it.
Solar-Powered Vents
Solar-powered vents are a type of active vent. They use solar panels to power a fan, which blows air out of the attic. This helps to keep it cool and prevents moisture build-up.
Each of these vents have their own advantages and disadvantages, so it is important to choose the type that best suits your needs.
How to Tell if a Roof is Vented?
There are a few ways to tell if a roof is vented. One way is to look for soffit vents. Soffit vents are the openings on the underside of the roof that allow air to flow into the attic. If you can’t see any soffit vents, you can check for ridge vents.
Ridge vents are vents that are installed along the ridge of the roof. They allow air to flow out of the attic and help to keep the attic cool. Another way to tell if a roof is vented is to look for gable vents.
Gable vents are vents that are installed in the gables of the roof. They also allow air to flow out of the attic and help to keep the attic cool. If you don’t see any of these vents, it’s possible that the roof is not vented.
