Shoulder & Crown Diagram

On most masonry chimneys, there is a “Crown” on the very top, and a pair of “Shoulders” where the chimney flares out. Like your home’s roof, these Horizontal surfaces are designed to keep harmful rain water from penetrating down into the brickwork of your chimney. Because these horizontal surfaces are totally exposed to all the elements (sun, rain, heat, cold), they generally begin to crack and develop leaks in short order. Water leaks in masonry chimneys cause more damage as a whole than any other element…. including chimney fires!!

If your crown and/or shoulders are cracked and weathered, your chimney is suffering more than you know! Every time it rains, water seeps down into the top 3-5 layers of brick which causes the mortar to prematurely become soft, thus allowing the bricks to become loose. If repairs to the crown and shoulder aren’t made, your chimney’s brickwork will eventually loosen and you’ll likely need to have the top several layers of your chimney rebuilt. Such repairs are often $1000-$2000!
