RidgeMaster® Plus

HomeProductsRoofing Accessories • 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” (229mm) or 11” (279mm) widths.
Low-profile design is unobtrusive, but also crushproof with nailing supports and structural ribs; withstands falling tree branches, hammer blows and resists cracking.
Self-aligning interlocking ends deliver quick alignment and ensure blocking of weather and insects. Built-in end caps adjust to roof pitch while ship-lap design allows for expansion and contraction during temperature extremes. Limited Lifetime Warranty.
