In most cases cracked tiles are caused by old age and thermal shock. Thermal shock is the severe temperature when soot or creosote ignite's in a chimney or vent during a chimney fire. Imagine the same type of cracking when you put a hot glass into cold water, causing the glass to crack and shatter. Although rare, settling of the house or lighting strikes will cause crack flue tiles.
Yes, they are! Tile liners expand and contract as they heat up and cool down. This means that when your chimney inspection is done, your tile liner is at its coolest point, and therefore, the cracks are at their smallest point. When the tiles heat up again, the cracks will open up, allowing soot, gases and heat from inside the flue to damage the house.
