Abstract: An apparatus for securing and stabilizing a ladder and extension ladder structure relative to a dwelling is provided, wherein the apparatus initially includes a plurality of arcuate arms mounted adjustably relative to tracks, wherein each track is secured to opposed ladder legs of an associated ladder structure. The arms each include anchor blocks, and the arms forward distal ends are mounted within cavities of each respective anchor block for positioning each anchor block upon a roof top surface. A further aspect of the invention includes organization for positioning and mounting the anchor structure relative to a bottom surface of a roof or to a vertical wall surface to include legs mounted adjustably relative to each ladder leg, wherein each of the legs are formed in an extensible configuration to include anchor structure mounted to each forward distal end of each of the legs.
