How to Choose Right Ventilation For Your Roof

The roof of your home is more complex than you think. For a proper roof function, it is necessary to have a ventilation system that helps control the ideal temperature, maintain optimal air circulation, and prevent overheated air and moisture from causing damage to your attic and roofing structure.

You should know there are two types of roof vents systems: intake vents and exhaust vents. Ensure you have the correct distribution of these because each house can vary due to the overall layout.

# Intake System

This system allows outside air to get into the attic and ventilation spaces and, they should be along with a roof assembly with the lowest eaves at or near soffits.

Soffit vents are the best option for intake vents because they allow the air to exit through ridge vents or hood vents. A soffit provides good protection against possible weather infiltration and helps prevent moisture from building up. If your house doesn’t have a soffit use a vented drip-edge vent.

Electric-powered vents are the ultimate air movers but are unnecessary for most situations. The gable vents can help by allowing air in or out, but they do not let the air flow evenly throughout the attic.

# Exhaust Vents System:

This one is usually installed on the highest part of the roof and its purpose is to allow clean air, as it pulls odors, fumes, and moisture from the attic and ducts to be expelled from the home and prevents ice dams in your roof. In a few words, fresh air enters the building through leaks in the building structure and balances the pressure. It works together with the intake ventilation system.

An exhaust vent system reduces the pressure inside the building and is relatively simple and cheaper. Generally, this system has one fan connected to a centrally located home exhaust point. Remember, a higher percentage of the exhaust ventilation system than the intake ventilation is less proper for hot places because humidity prevents the reduction of air pressure.

Now you may be wondering, what is the right proportion of each type of vent for my roof? Here is when your contractor gives you the answer. But, if you want to surprise him, tell him this basic rule: One vent is needed for every 300 square feet if a vapor barrier is installed in the attic. If there is no vapor barrier, you should have one vent for every 150 square feet.

Maybe you can get a discount after that demonstration of knowledge.

A correct vent system and having a proportional balance between intake and exhaust vents help prolong the roof’s life and reduce electricity costs.
