Detroit was a horse and buggy town when German immigrant
Frank Hesse started a new business, the Detroit Cornice
& Slate Company in 1888.
Detroit Cornice & Slate is still around, still in
the Hesse family, and still installing slate and tile
roofs the old-fashioned way. It is in its' fourth
generation of Hesse family management .... with the
fifth generation already active in the firm.
