Curved chimneys & sulphation: this article describes the cause, inspection, and evaluation of curved chimneys. Often a brick chimney is visibly curved or leaning above the building roof line. If the cause is sulphation it is well understood, but further inspection of the chimney flue and the chimney stability are in order since a badly damaged brick chimney may have an unsafe flue or may collapse. Our page top photo shows a curved brick chimney above the rooftop of a home in Hudson, NY. Look closely at the left edge of the brick chimney to best see this deformation. Also see Chimney Leaning, Separation, Movement.
