A mounting assembly is provided for puncture-free attachment of a snow guard system to a roof seam. The assembly comprises a mounting block, at least one clamping pad, and an actuation member. Once actuated, the clamping pad prevents relative movement between the mounting block and the seam. At least one clamping pad positioned adjacent a groove located in the base of the mounting block. The clamping pad includes a first side having at least one primary contact surface outwardly protruding a first distance from the first side. The clamping pad also includes at least one secondary non-spherical contact surface protruding a second distance from the first side. In the preferred embodiment, the second distance is less than the first distance thereby making the primary contact surface(s) the first to engage the seam upon actuation of the pad. Preferably, the clamping pad includes a second side having at least one protrusion for engagement with a first end of the actuation member. Prior to actuation of the clamping pad, this second side is initially received within the groove. When actuated the actuation member is moves the clamping pad toward the seam to cause at least the primary contact surface to engage the seam, thereby preventing relative movement between the mounting block and the seam. According to the second embodiment a plurality of clamping pads are utilized. These clamping pads are preferably located on opposite sides of the groove and more preferably offset from one another such that the respective contact surfaces of each pad alternately engage the seam.
