Atlas Pro-Cut® Shingle Starter Strips protect the roof edge and provide the hold-down features needed to provide high wind resistance at the critical roof areas of the eaves and rakes. Starter strips for roofing are designed as a starter course before installing the first course of shingles. The Pro-Cut® Starter Strip is an easy, cost-saving alternative to the traditional method of cutting tabs from 3-tab shingles to form a starter course.
