Final answer:
Masonry chimneys should have a cap made of stone, metal, or concrete with a roof made from wood.
Step-by-step explanation:
Masonry chimneys should have a cap made of stone, metal, or concrete with a roof made from wood. Wood, brick, stone, or mud bricks were stacked and piled to construct buildings. However, wood did not last as long as stone and would rot away over time. Therefore, it is important to have a cap made of a durable material to protect the chimney.
