Roll Crush (Carpet)
Floor Detective® Claims and Conditions Guide
Summary
Roll crush is an appearance condition that develops when carpet pile remains under sustained compression while stored or transported in roll form. Continuous circumferential pressure causes yarns to lean or flatten, altering surface reflectance patterns without changing dye or fiber composition. Observable effects commonly include light and dark banding across the carpet width that reverses with viewing direction due to pile orientation changes. The condition develops after manufacturing during storage and handling and affects appearance only without indicating fiber damage, backing failure, or structural deterioration. See also Crushing, Shading / Footprints / Vacuum Marks, and Carpet Problems for broader context.
