A tented roof is like a big top for a circus. It is made up of fabric or another material that covers a space like a roof. The fabric is stretched tight and held up by poles, just like how you might hold up a blanket fort with broomsticks. It can be used to cover an area and keep people dry in case it rains or to provide some shade from the hot sun. Tented roofs are often used for events like outdoor weddings, concerts or fairs. They make things look fancy and exciting, just like how a circus tent makes you feel.
