Roof vents form the base of a home's attic ventilation system, helping it breathe while preventing roof system damage year-round. That's why it's important to understand how the various components work together to create a balanced, effective attic ventilation system.

The shingles are the outermost layer of your roof and they help protect you from the sun's rays, rain, snow, and wind.
