Abstract: The present invention relates generally to modular flashing systems for use in the construction industry. It provides a plurality of modular flashing entities and modular trim flashing elements designed to be used in concert. The articles provide a unitary structure essentially impervious to atmospheric and environmental elements. The invention provides a modular flashing entity including a first surface, a second surface having a proximal edge and a distal edge removed from the proximal edge, as well as a left end and a right end, wherein the first surface joins the second surface along the proximal edge, and a third surface joined to the second surface along the distal edge thereof In many embodiments an additional fourth surface joined to a left end or to a right end of the second surface and further joined to the third surface. These are useful as drip caps and flashing pans when installing items such as doors and windows.
