11” HipMaster®

Enhance roof ventilation at the hip with a patented triple-baffle system engineered to keep blowing rain and snow from getting in. In addition, an internal filter blocks out insects, leaves and pine needles. The low-profile design, for roof pitches 3/12 to 12/12, is unobtrusive. Nailing supports and structural ribs make the HipMaster crushproof, to withstand falling tree branches and hammer blows, and it resists cracking. Self-aligning, interlocking ends make it easy to install correctly. Built-in end caps adjust to the roof pitch while the ship-lap design allows for expansion and contraction as temperatures change. Can be joined with RidgeMaster Plus ridge ventilation.
