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.

Most homeowners don't think about all the components that make up the roof of their home, but there's a lot going on underneath your shingles. The shingles are the outermost layer of your roof and they help protect you from the sun's rays, rain, snow, and wind. Digging deeper, there's another layer of protection between the roof deck and the shingles: underlayment, which plays a vital role in helping protect your home from moisture damage.
