What is Ballast?
Ballast is a heavy material, typically aggregate, used to secure roof membranes on flat roofs. This loose-laid material is essential for holding down roofing systems and is commonly composed of gravel, stone, slag, pea gravel, or mineral granules. By using ballast, flat roofs benefit from the weight and gravitational force that stabilize the membrane, preventing it from being lifted by wind or other elements.
Types of Ballast Materials
- Gravel
Gravel consists of small rock fragments, which are classified by mineral type, size range, and other specific characteristics. It’s widely used in roofing due to its ability to provide solid, uniform coverage. - River Rock
River rock is a smooth stone that has been naturally weathered by moving water. Its rounded edges make it ideal for built-up roofs (BUR) as it minimizes the risk of puncturing the roofing membrane. - Slag
Slag is a glass-like stone that’s typically smaller than river rock. It’s often used in BUR systems due to its smooth texture and durability, providing a reliable ballast material for roof protection. - Pea Gravel
Pea gravel, also known as pea shingle, is a small, rounded stone often used in roofing applications. Its compact size and smooth edges make it a popular choice for ballast, offering excellent coverage and stability.
