Roof ventilation is one of the more important components, whether homeowners realize it or not. Vents placed in the attic of a home, when done effectively, can remove heat and moisture from the attic that can lead to serious damage to both the roof itself, and the home’s structure. In order to be effective, ventilation must be placed with consideration to the design of the roof, and the typical outside weather conditions.
Problems That Occur Due to Improper Roof Ventilation
- Rusting metal – if moisture is able to form in an attic, it can cling to metal surfaces. This can ultimately lead to the formation of rust on items like nails and screws. As these rust, they no longer offer the same stability to attic supports, ducting, and other essential things that may be present in your attic.
- Dry rot and mold – mold, spores, fungi, and dry rot can all form if the insulation in an attic traps moisture.
- Shortened life of air conditioning – air conditioning and cooling units are forced to work overtime when there is moisture trapped in an attic. The more an air conditioning unit is used, the shorter its life becomes. In this case, that is entirely preventable.
Types of Roof Ventilation
Exhaust vents, which are typically placed towards the ridge line of the roof help remove air from the attic. Intake vents serve their purpose by bringing fresh air into an attic, and are typically located around the eaves of the roof. There are a variety of vent types, and can be better options depending upon the style of the roof. These ventilation types include:
- Power vents
- Static Vents
- Turbine Vents
- Ridge Vents
- Soffit Vents
- Cupola Vents
A professional roofer can help ensure that you have the right type of ventilation installed in your home. They will also determine exactly how many vents you require based on the square footage of your attic, and the architecture of the roof.
