Patented added-pitch design shows more shingle profile and less vent opening for clean, eye-pleasing aesthetics. It is easily adapts to a peak vent or flash vent. Patented internal baffle keeps blowing snow and rain from entering, while internal filter blocks out insects, leaves and pine needles. Its 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.
