US Patent 10544590 Synthetic starter tile for an angled roof interface

A synthetic starter tile for an angled roof interface can include a non-planar body defining a longitudinal axis. The body can include an overlap edge perpendicular to the longitudinal axis, an exposed edge opposite the overlap edge, an overlap portion extending from the overlap edge, and an exposed portion extending from the overlap portion to the exposed edge. The exposed edge can form at least one acute compound angle, ACA, with respect to the longitudinal axis.
