Each rail includes a forward and rear hook plate, with the forward hook plate including a bifurcated hook member, and the rear hook plate including a bifurcated rear hook member and a single hook forward portion. An anchor member is provided including a plurality of legs secured radially to and in equally spaced relationship to a central support, with each of the legs including a spring mount to permit deflection of the legs in securement to a shingle-type structure, with a second leg bisecting a plurality of adjacent legs rigidly mounted to the central plate.
