11" RidgeMaster® Plus

Patented added-pitch design shows more shingle profile and less vent opening for clean, eye-pleasing aesthetics. Easily adapts to a peak vent or flash vent. For roof pitches from 3/12 to 12/12. Patented internal baffle keeps blowing snow and rain from entering, while internal filter blocks out insects, leaves and pine needles. Available 9" or 11" widths.
