Chimneys
The type of use for the chimney will affect its life span. A chimney used for heating will deteriorate faster than one used infrequently for a fireplace. This also applies to chimneys which have clay liner or metal inserts. Most of the serious deterioration occurs above the roofline. The chimney cap is usually the first component that needs replacing. As with roof coverings, the angle of the predominant wind, sun, trees, vines and water infiltration will greatly affect the life span.
