What is a Chimney’s Primary Purpose?

A chimney is a structure which provides ventilation for a stove, furnace or fireplace. Chimneys are typically vertical to ensure that the gases flow smoothly. On a pitched roof, where a chimney penetrates a roof, flashing is used to seal the joints. The down slope piece is called an apron. The sides receive step flashing and a cricket is used to divert water around the upper side of the chimney underneath the flashing.

Extreme weather, combined with the right circumstances, can cause degradation of masonry wall surfaces due to frost damage. Masonry materials deteriorate quickly when exposed to the freeze/thaw process, in which moisture that has penetrated the materials periodically freezes and expands causing undue stress. Water in the chimney also causes rust in the steel and cast iron, weakening or destroying the metal parts.

Why is Maintaining a Chimney so Important?

Chimney caps, also called rain covers, are the most inexpensive preventative measure that a homeowner can employ to prevent water penetration and damage to the chimney. Caps will also prevent birds and animals from entering and nesting in the chimney.

The chimney crown is the top element of a masonry chimney. It covers and seals the top of the chimney from the flue liner to the chimney edge. The crown provides a downward slope to direct water from the flue to the edge of the crown and the overhanging drip edge helps prevent erosion of the brick and mortar.

Deteriorated mortar joints on the chimneys’ exterior are entry spots for water. Proper mortar joints have no gaps or missing mortar. A common repair for mortar joints is called repointing where the existing mortar joint is cut and repacked with new mortar.

Do I still need my Chimney?

If the chimney has deteriorated past the point of a simple repair and is no longer in use, it can be taken down and sealed up however this is a dangerous job that must be left to the professionals. Chimney’s in older homes that were once used for a wood-burning stove can usually be removed and roofed over.
