The invention is a pair of multi-function kneepads adapted for use on inclin ed roofs. Each kneepad is comprised of a wedge of expanded polystyrene or similar lightweight material capable of supporting the user's weight. The acute dihedral angle o f each wedge is approximately equal to the pitch angle of the roof on which the kneepads are being used, thereby providing a substantially horizontal upper kneeling surface wh en the wedge is oriented towards the roof's peak. Each wedge's lower surface is typically affixed to a soft rubber pad that prevents premature abrasion of the polystyrene wedge an d improves grip onto the roof's inclined surface. Each wedge's upper surface typically includes a soft foam layer that serves as an ergonomic kneeling pad for the user. An attachment harness secures the kneepads to the front of the worker's kneecaps and shins . The attachment harness may also be configured for securing the kneepads to the soles of the user's feet, thereby improving comfort in the standing posture.
