Generated explanation

Three individual wood roofing shingles illustrate curling, cupping and splitting. The left shingle curves along its length, lifting its exposed end. The middle shingle is cupped across its width, with raised sides relative to its center. The right shingle has a lengthwise split extending inward from the butt edge. These are examples of wood-shingle distortion and damage, rather than an installed roof assembly.
