A tar and gravel roof, commonly referred to as a built-up roof (BUR), is widely used for flat or low-pitched roofs. It consists of several layers of asphalt or ***umen, topped with gravel to enhance its strength and durability. These layers form a reliable waterproof barrier, helping to prevent leaks. Although tar and gravel roofs are known for their longevity and low maintenance, they are heavy and usually need professional installation. Regular upkeep is important to ensure the roof’s effectiveness, as it may require repairs following severe weather. With proper care, this roofing type can last for many years.
