What Is a Ridge Vent In Roofing?

It’s one of the many types of roof ventilation. You’ve probably seen vents like the turbine (sometimes called whirlybirds) and box vents on roofs.

But what are ridge vents on a roof? They are vents that run the entire length of your roof’s ridge (its highest point). With ridge vents on a roof, your once bulky ventilation system is hidden from view. 

What’s the purpose of a ridge vent on your roof?

Well, your house needs to breathe. It does this through its ventilation system, a combination of intake and exhaust vents that keep air flowing. 

Ridge vents are one of the most efficient ways to keep your house safe and healthy, whether your roof uses active or passive ventilation. 

Active ventilation requires power.

These are the turbines and solar-powered vents you’ve probably seen before. An active ridge vent system uses baffles, tiny chutes to facilitate airflow. 

Passive ventilation relies on natural forces. 

They are much more common among older homes. They push air through your home by using natural means like the wind. Passive roof vents ridge systems don’t use baffles. Unfortunately, these systems leave a small enough opening for insects and some precipitation to enter.

Good ventilation is vital to your roof’s longevity and to your home’s health.

Poor or no ventilation traps heat and moisture. Trapped heat deteriorates your roof’s adhesives and causes shingles to crack. Lowering your roof’s lifespan and leading to costly repairs. Trapped moisture leads to mold and mildew, exposing your family to serious health risks. 

Proper ventilation protects your home and your family from these risks. And ridge vent roofing is one of the most efficient ways to do so!

How is your roof’s ventilation? Keep an eye out for these telltale signs. 

• Your upper rooms are abnormally hot, especially as we approach summer.
• A sudden increase in your heating or cooling bill
• Abnormal ice buildup along your roof’s edge.
• Rippled, warped, or cracked shingles.
• Rust or corrosion of metal components like your attic’s electrical boxes or your HVAC system.
• Water damage or frost on your ceilings or in your attic.
