Abstract
The invention provides a one piece shingle for use on roof ridges and hips. Shingles of the invention are preferably formed from synthetic materials and preferably comprise a blend of high and low molecular weight polyethylene resins. The unique blend of materials provides a shingle that is both strong while retaining sufficient flexibility to permit the shingle to bend to accommodate a variety of pitches at a ridge or hip. Unique features of the shape and structure of the shingle also make it particularly suited to hip and ridge applications. Furthermore, methods of manufacturing hip and ridge shingles are also disclosed.
