Ubiquitous to such early, eaveless buildings is the rake board, the side elevation's equivalent of a fascia, more or less. In the absence of a roof overhang, rake boards protect the junction between a building's roof and its side walls from water infiltration. Though most common to masonry buildings (1), rake boards aren't unique to a particular construction method — log, frame, brick, and stone structures alike make use of them.

On masonry structures, rake boards tend to coexist, almost by necessity, with flush chimneys. Among higher-style Federal buildings, they occasionally feature dentils or scalloped carvings, and they often terminate, on the facade, at proper cornices.
|Early house; Clifton, Greene County, Ohio. This dwelling — bizarrely vertical, and almost tower-like, in its proportions — features the usual flush chimney and rake boards.|
|Kitchen wing, John Knott House (1828); Miami Township, Greene County, Ohio. The rake boards may this home's least noteworthy feature. Most fascinating are the two-story porch and divided ("Dutch") door.|

1) Why? Largely because early masonry buildings were more likely to outlast frame and log ones.
