ABSTRACT:
Snow stop has a base, a snow-hindering member, and a convolute hook. The convolute hook includes a forward section, a first opening section, and a further opening section; the convolute hook can be present at a distal end of a base of the snow stop, and it also can include a distal base bend section, and an extending section. The snow stop can have its base and convolute hook made to include sheet metal, for an example, copper. In general, the convolute hook can act as a spring. The hook minimizes or eliminates crushing of the same, and the snow stop can be retro-fit in slate, shake and shingle roofs efficiently.
