12 inches tall. 3″ taller and has a 2″ larger flange than the Bullet Boot. The Bullet California Boot is designed for California where a wider flange is used. Order 16 units (same color Bullet California Boots) to qualify for Free Shipping. Protective mesh varies in colors and may not match color of Bullet Boot.
Fitting: Remove interfering shingle nails around the perimeter of the roof opening. Depending on the application, apply a bead of shingle adhesive along the bottom of the flange, and slide the top end of the Bullet Boot up and under the shingle. Allow the bottom vent flange to lie on top of the shingles or cut shingle to fit.
Mounting: Care should be taken in keeping the Bullet Boot properly aligned. Nail in place using 1-1/4” coated or stainless roofing nails spaced 6” to 8” on center, or at least 3 per side, maximum of 1” from the outer edge of the flange, and 1-1/2” from each corner. Roofing cement should be applied to all shingle edges and nail heads to prevent water infiltration. In severe weather coastal hurricane zones, it is recommended to caulk around the entire Bullet Boot perimeter, under the vent flanges, and near the outer edges (7108 Permathane Sealant).
