Ridge caps over standing seam roofs are often installed over what spacing to provide ridge venting?

Ridge caps over standing seam roofs are often installed over what spacing to provide ridge venting?

• A. 2x2 wood battens spaced to provide ridge venting
• B. 2x4 wood battens spaced to provide ridge venting
• C. Metal hat channels spaced evenly
• D. No battens used at all

Answer: (A)

The essential idea is creating a continuous vent path at the ridge so air can move from soffit vents up and out through the ridge. To do that, small furring battens are installed under the ridge cap to hold a thin gap between the cap and the roof surface. Using two-by-two wood battens spaced to provide ridge venting gives a stable, shallow breakout that maintains that air channel while giving something solid to nail the ridge cap to. This setup keeps the vent path open and predictable along the entire ridge. Choosing no battens would eliminate the vent channel entirely, and metal hat channels don’t provide the same continuous opening for airflow. Larger battens (like 2x4) could raise the cap more than needed and alter the vent geometry, potentially hindering airflow.
