ABSTRACT:
A patch for patching holes in roofs, particularly holes left when roof vents are removed, includes a polymeric tray having extending peripheral flanges and an attachment plug (preferably made of lignocellulosic material such as plywood) depressed within the tray so that its upper surface is flush (or nearly so) with the flanges. The attachment plug (and the portions of the tray floor below it) may be fit into a roof hole, with the flanges resting on surrounding areas of the roof. The flanges may then be affixed to the roof so that the tray forms a supporting web which maintains the attachment plug in the hole. Shingles or other roof coverings may then be fastened to the attachment plug, and to the surrounding flanges and the roof beneath them, so that the hole is patched and the prior presence of the hole is no longer visible.
