Some homeowners may hesitate to install ridge vents if they don’t know what signs to look for.

How Much Venting Do You Need for Your Attic? ➖ Some older homes were not built with ridge vents ➖ Risk of water intrusion without baffles ➕ Reduce the chance of mold development by ventilating and circulating warm air, reducing moisture buildup ➕ Increase energy efficiency by helping homes stay cool in summer ➕ Help attics stay cool in winter to prevent the formation of ice dams from melting and refreezing snow Let’s explore the pros and cons of this facet of a roofing system. Roof ridge vents come with many benefits for proper ventilation of an attic space. Baffles also help deflect wind-driven rain, snow, insects, and pests.īenefits and Drawbacks of Roof Ridge Vents Ridge vents without baffles sometimes rely more on the wind’s orientation to create ventilation, and off-ridge vents without baffles can easily leak. It helps redirect wind over the vent to create a vacuum effect that pulls air out of an attic instead of relying on basic convection forces. These provide a vital function in increasing energy efficiency for many homes, regardless of the type of roof.Ī baffle is an addition to a ridge vent. Their exact configuration varies from manufacturer to manufacturer. Ridge vents come with or without baffles. They’re typically installed on the peak of the roof because the ridge line is often where warm air collects, but there are also off-ridge vents. Ridge vents are made by cutting a slot out of a length of roof sheathing, which is then covered with fibrous material and a cap.
