Ridge Cap Calculator

How It Works

Ridge caps cover the peak of the roof where two slopes meet. Shingle-style ridge caps come in bundles covering about 33 linear feet. Metal ridge caps come in 10-foot pieces with a 2-inch overlap. Hip caps are the same product used along the angled edges of a hip roof. Ridge vents run along the ridge and work with soffit vents to create natural airflow through the attic — this is the most effective ventilation method. When installing ridge vents, a 1-inch slot is cut on each side of the ridge board. Always seal the ends of ridge vents to prevent wind-driven rain infiltration.
