Roofing insulation securement plates have multiple projecting ribs of cascading or successively differing height or projection profiles, with an innermost rib have a highest profile and successive radially outboard ribs having successively smaller heights or projection profiles for an increasing degree of flexure of the plate from the center to the outer perimeter of the plate. The plates additionally have an aperture located at the center of a centrally located recessed region of the plate through which a fastening device may be inserted for securement of the plate to an underlying roofing substrate.
