Abstract
Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.
