Abstract: The improved gutter shield assembly is arranged for attachment to a roof constructed of partially overlapping shingles which define thin spaces between them. The shield assembly includes a mesh-like barrier which prevents debris from entering the gutter. The barrier has a plurality of openings for permitting the passage of water from the shingles through the barrier and into the rain gutter below. Attachment devices which are devoid of nails are used to attach the shield assembly. Such attachment devices may include J-shaped hooks, bent tabs or both. The barrier is thereby attached while yet avoiding piercing of shingles and consequent impairment of the rainproof integrity of such shingles. In another embodiment, the barrier is permanently attached to the roof.
