Flashings and Copings:
Ridges and Hips

Description: There are many ways to construct copper ridge and hip flashings. The ridge flashings form a cover over the roofing material. The anchoring methods vary.

Most hip installations involve the weaving of copper flashing sheets between roofing shingles.

The minimum recommended weight for ridge and hip flashing is 16 oz.

A. Ridge at Shingle Roof The flashing is nailed to the sheathing after the shingles are installed. Then the flashing is covered by shingles applied end to end across the ridge. These shingles are nailed with neoprene washers.

B. Ridge Vents Two conditions are shown, a shingle roof on the left and a copper roof on the right. In each case, wood blocking frames the perimeter of the roof opening. The preformed copper ridge vent is nailed to the blocking at 3" O.C. and is formed from a minimum of 20 oz. copper.

For the shingle roof, the lower edge of the vent is hemmed and held by cleats at 12" O.C.

For the copper roofing, the lower vent edge is locked into the upturned edge of the roofing pans.

A bronze screen is soldered to 2" diameter holes in the vent frame punched at 6" O.C.

C. Spring and Batten Ridge This detail involves the use of a ridge batten anchored to the ridge pole. Copper base flashing is installed on both sides of the batten with brass screws and lead washers. The copper ridge cap is locked into the base flashings. The base flashings maintain contact with the shingles by spring action.

D. Screwed Down Ridge This ridge cap is made from a one piece copper flashing. It is fastened to the roof sheathing by brass screws after the shingles have been installed.

E. Concealed Hip Flashing In this detail the hip flashing is concealed. Small copper flashing squares are inserted between successive layers of shingles during installation. They are then covered by shingles applied end to end along both sides of the hip.
