Mounted to any roof pitch or mounted vertically, the Ladder Safety Rest helps protect shingles and gutters from damage typically associated with ladder use. The device is secured to a roof with a plate held by four screws; the ladder is then held in place between the two hand grips with a safety chain tested for strength and durability to prevent shifting or slipping. Ladder Safety Rests are available for $300 on the manufacturer’s website. laddersafetyrest.com
