Cracking granule loss in asphalt overlay appliqué shingles widespread cracking and irregular but sometimes circular shaped areas of granule loss in the surface of the shingles at the asphalt overlay result from the excessive differential shrinkage of the asphalt overlay and the poor bonding of the asphalt overlay to the underlying layer of granules during the manufacturing process.
