A jack arch roof is a type of masonry roof structure, constructed using brick, stone, or earth block arches supported by small wooden, steel, or concrete beams. The arches form the main structural elements of the roof, distributing the weight of the roof load to the supporting beams. The construction process involves laying the arches in a curved shape, to create a strong and stable roof structure. Jack arch roofs are known for their durability and ability to span wide areas.
