Just installed this copper finial on a turret in Lakewood, near Cleveland, Ohio.
The old finial was made of galvanized steel, rusted through and, if not for the interior wood support, would have fallen off the roof. We were able to copy the original pieces and reproduce in copper.
The sad thing is, this finial is going up on a house that has had the rest of the exterior re muddled with replacement windows and vinyl siding and looks pretty bad. The neighbors house on the other hand, has many of the original windows, siding and trim, but is missing their turret finial.
To their credit, the owners of the re muddled house are currently restoring the interior and hope to work on the exterior at some point.
