Chimney Crown Options: many shades, one function
Example shown is one of our stone (limestone) ledge crowns.

All of the crowns that Minnesota Chimney installs function similarly in their duty to shed water and maximize runoff. The difference in chimney crown options is mainly of cost and appearance. All are carefully crafted and carry a 5-year limited warranty.

Poured concreteThe standard poured concrete crown is a sturdy structure crafted from concrete poured into a metal crown form. It is reinforced with rebar and wire mesh for strength, and has expansion joints around the flue tiles to accommodate contraction and expansion during the freeze/thaw cycle. This crown comes standard with every chimney repair job we perform, at no additional cost.

Limestone ledgeThe limestone ledge crown consists of a slab of limestone that overhangs the chimney by at least 2 inches all around, with a concrete slope formed on top and a rugged rock-face edge. This option is also reinforced with rebar and wire mesh and features expansion joints around the flue tiles, essential to hinder the formation of cracks in the crown. A drip edge (a groove in the underside of the overhang) can be created to help prevent water from running down the sides of the chimney.

Stylized formThe most elegant of options, the stylized form crown is a sturdy 4 inches thick, built of crack-resistant concrete further strengthened with rebar and wire mesh. It overhangs the chimney by 2 inches on all sides, and the form itself contains a built-in drip edge. The stylized form is available in 2 styles: Top Rib (shown) and Victorian, both of which serve to beautifully adorn your chimney.
