Abstract: The present invention relates generally to a roof clamp and, more specifically, to a plastic clamp that removable secures itself between shingles to attach a holiday decoration to the roof. The present roof clamp comprises a textured, rectangular backplate that is pushed under adjacent shingles. Two prongs extend from a center portion of the backplate such that they travel between the two adjacent shingles. A rectangular front plate is hingedly attached to the back plate along their lower lengths. The two prongs travel through two corresponding apertures on the front plate to lockingly engage the roof clamp in place by means of a catch release. A narrow plastic hook extends from the lower side of the backplate. A gripping prong is hingedly attached to the hook at its terminal end. The gripping prong is capable of rotating such that it can be manipulated to reconcile with and grasp the rigid angle of the decorative element it is holding.
