Heritage, Valley application supplement

Heritage

Valley Application Supplement

After installing the underlayment and valley flashing according to the manufacturers’ instructions:

• Apply the first course of shingles along the eaves of one of the intersecting roof planes and across the valley.

Note: For proper flow of water over the trimmed shingle, always start applying the shingles on the roof

plane that has the lower slope or lesser height.

• Extend the end shingle at least 12” onto the adjoining roof. Apply succeeding courses in the same

manner, extending them across the valley and onto the adjoining roof.

• Press the shingles tightly into the valley.

• Use normal shingle fastening methods.

Note: No fastener should be within 6” of the valley centerline, and two fasteners should be placed at the

end of each shingle crossing the valley.

• To the adjoining roof plane, apply one row of shingles vertically facing the valley and 2” back from the

valley centerline.

Note: For a neater installation, snap a chalkline over the shingles for guidance.

• To complete the valley, apply the shingles on the adjoining roof plane by positioning the tip of the shingle

of each row at the 2” point from the centerline where the edge of the vertical shingle has been applied
covering the vertical shingle.
