Abstract
An apparatus (10) for controlling the movement of snow and/or ice along/across selected areas of a roof (16), such as a metal, raised seam roof, is disclosed. The apparatus (10) comprises clamps (12) interconnected by at least one cross-member (18). The clamps (12) frictionally engage an external surface of a roof ridge (14) such that the clamps (12) are secured to the roof (16) without piercing the roof (16). The cross-member (18) can be straight or bent and a mechanism can be provided for adjusting the height of at least a portion of the cross-member (18) over the roof (16).
