ABSTRACT:
A mounting and attachment system, which mounts a continuous snow rail for snow protection above the seams of a metal roof and also attaches lower members or snow flags between the seams to stop the snow from sliding under the seam. This system reduces the requirement for holes and threaded holes in the mounting block. The mounting block has a slot which runs therethrough to fit over a raised seam. This slot can have parallel walls or can be shaped to match a particular seam. This block also has slots or linear indentations on the sides or ends in a direction perpendicular or parallel to the slot for the seam. A snow rail long enough to connect two or more of the seam-mounted blocks together. Finally, a top rail may be secured parallel to the seam and mounted on two or more seam mounted blocks.
