Designed for roof pitches from 3/12 to 12/12, the RidgeMaster Plus easily adapts to a peak vent or flash vent. A patented added-pitch design reduces the visibility of the vent opening, letting the shingle profile take center stage. The patented internal baffle keeps blowing snow and rain from entering, while an internal filter blocks out insects, leaves and pine needles. Nailing supports and structural ribs make the RidgeMaster Plus crushproof, to withstand falling tree branches and hammer blows, and resist cracking. Built-in end caps adjust to the roof pitch while the ship-lap design allows for expansion and contraction as temperatures change. For more information, visit
