Surfaces:  The Bennington Shingle is designed to be installed over solid substrates only on roofs and walls with slopes of 3:12 or greater. Acceptable substrates include exterior grade plywood (1/2" minimum thickness) or well-seasoned lumber.

Underlayment:  Surface to receive Bennington Shingles should be covered with two layers of Type 15 felt or one layer of Type 30 felt for the field of the roof. In locations subject to ice build-up, two layers of Type 15 felt should be applied shingle fashion cemented together with approved material between the ply's extending from the eave up the roof to a point at least 36 inches inside the exterior wall line of the building.

Edge Strips:  Copper edge strips (drip edge) should be installed continuously along eaves and gable rakes. The roof flange is secured to the substrate with copper nails spaced 3" apart.

Shingles:  Installation may begin at any location along the eaves and proceed upward. First shingle course locks over previously placed edge strip; subsequent courses lock into course below. Ends of each shingle butt with a space of approximately 1/16" between shingle ends. Prefabricated joint pans are placed under butt joints. Butt joints are to be broken at least 12" in adjacent courses. Each shingle is secured to the substrate with five copper nails spaced approximately 12" apart through pre-punches holes. At gable rakes shingles are cut and folded over to form a 5/8" lock, which hooks around a previously placed edge strip. At valley shingles are cut and folded over to form a 5/8" lock, which hooks into the double fold in the previously placed valley flashing. Chimneys, vent stacks, and similar projections are flashed with copper sheet.

Valleys:  Valleys should be of copper in 10-foot lengths. Each length is nailed at the top edge only and laps the lover length not less than 6" in direction of the flow. Outer edges of valley flashing are secured with copper cleats spaced 18" apart and secured with two copper nails.

Hips and Ridges:  Hips and Ridges are finished with special copper caps as manufactured by Paradigm Shingles, Inc.. Caps are placed over the shingles, then locked into place, and secured with two copper nails.
