2. Do not nail asphalt shingles to metal open valley flashings.

H. Ridge Vents: Install continuous ridge vents over asphalt shingles according to manu-facturer's written instructions. Fasten with roofing fasteners of sufficient length to penetrate sheathing.

I. Ridge and Hip Cap Shingles: Maintain same exposure of cap shingles as roofing shingle exposure. Lap cap shingles at ridges to shed water away from direction of prevailing winds. Fasten with roofing fasteners of sufficient length to penetrate sheathing.

1. Fasten ridge cap asphalt shingles to cover ridge vent without obstructing airflow.

3.6 RECONDITIONING EXISTING CHIMNEY CAP FLASHING

A. Recondition and reuse existing chimney cap (counter) flashings. Remove old caulk-ing, loose rust, and other foreign materials. Prime all exposed non-copper surfaces with exterior grade metal primer and paint with two coats of exterior oil paint. The CO shall pick the color from manufacturer’s standard color chart. Seal all exposed

07311-9 edges with 25 year caulk as recommended for this type of use. Recondition metal crickets in a similar manner.
