With proper installation and regular maintenance, Built-Up Roofs can last 20 to 30 years or more. The number of layers and the quality of materials used in construction contribute to the roof's overall durability.
Built-Up Roofs are designed to withstand various weather conditions. The multiple layers and composition of bitumen provide excellent resistance to water penetration, ultraviolet (UV) rays, and thermal expansion and contraction.
The layers of bitumen in a Built-Up Roof create a waterproof membrane that prevents water from seeping into the building. The application of hot asphalt, or torching, ensures proper bonding and enhances the roof's ability to withstand water infiltration. This reliable waterproofing is crucial to protecting the structure and interior of the building from potential water damage.
Built-Up Roofs can provide good insulation properties, helping to improve energy efficiency. The multiple layers of bitumen and reinforcement materials contribute to thermal resistance, reducing heat transfer into the building and potentially lowering energy consumption for cooling and heating.
