ABSTRACT:
This invention is an integrally-formed entry door flashing pan that fits snugly in the threshold of a rough-entry door opening. The flashing pan has an upwardly projecting rear lip, upwardly projecting side lips, and a downwardly projecting exterior lip. The pan lies juxtaposed to the threshold subflooring with the side lips having felt building paper or other building wrap overlapping the same. The downwardly projecting exterior lip lies juxtaposed to the exterior of the building structure in which the rough entry door opening is formed. A entry door assembly can be placed on the flashing pan and secured to the sides and top of the rough opening without penetrating the watertight integrity of the flashing pan. The entry door is then trimmed out in the normal manner to provide an entry door flashing that is water proof and completely concealed when the building structure is completed.
