Abstract: An improved building eaves construction and eaves shield in which the shield comprises a first plate angled to match the pitch of a building roof underlying its normal roof covering, a second plate oriented to fit flush against the fascia board or exterior wall siding forming the roof edge, and a central, overlapping portion overlaying the roof edge and connecting the two plates. This central portion forms a downwardly opening channel into which the inner wall of a conventional gutter is inserted for attachment with the second plate to the fascia board or exterior wall siding to thereby prevent excess water, ice, or snow from backing up into the eaves area and damaging either the roof decking or the building interior.
