Ventilation is an essential component in the overall health of your roofing system. Vents are responsible for maintaining a steady flow of air through your attic space to help prevent moisture buildup in the attic and on the roof sheathing.

To determine if your home is properly vented, you need to understand some of the must-have elements of a functional and efficient ventilation system.

1. Balance

The right ventilation system will be balanced to provide your home with maximum air movement. Balance means that there are an equal number of intake and exhaust vents located on the roof, and that the size of the vents is equal. This symmetry ensures that a steady displacement of air will occur within your attic.

It is this displacement of air that prevents moisture problems from taking a toll on the structural integrity of your roof. Check your attic for balanced ventilation, and contact a roofing contractor for help if your ventilation system appears to be off-balance.

2. Proper Placement

It's not enough just to have an adequate number of vents installed in your attic, these vents must be placed strategically to ensure the efficiency of your ventilation system. Intake and exhaust vents must be located far enough from each other to prevent the accidental circulation of contaminated air.

When located in close proximity, an intake vent could bring the air released from an exhaust vent into your home. This reduces the efficiency and safety of your ventilation system, and an experienced roofing contractor should be contacted to help you relocate vents as needed.

3. No Obstructions

The vents in your attic can only work properly if air is allowed to move freely through them. Obstructions can significantly compromise the quality of your ventilation system and leave your home susceptible to water damage.

Have a roofing contractor install vent covers over each exterior opening. A vent cover is a mesh screen that will help prevent rodents, birds, and other pests from taking up residence in the vent pipes.

You should also have your vents inspected regularly to determine if leaves, twigs, or other natural debris have found their way into the vent pipes. Keeping all vents free from obstructions allows your home's ventilation system to work as efficiently as possible in protecting your roof against the damage that can be caused by excessive moisture.
