Advanced Commercial Roofing Installation Contractor in Whittier, CA
Commercial Roofing Installation Built-Up Roofing (BUR) Systems
Built-up roofing (BUR) systems provide reliable waterproofing and long-term protection for commercial properties. Our team installs these systems using multiple layers of bitumen, reinforcing fabrics, insulation boards, and protective gravel surfacing. Specialized equipment, including asphalt kettles, mop systems, and spreaders, is utilized to create a durable multi-layer membrane designed to withstand demanding conditions.
Proper substrate preparation is critical to the performance of a BUR roof. Surfaces are thoroughly cleaned, leveled, and primed before each ply is embedded with hot asphalt to form a continuous moisture barrier. A protective gravel surface is then applied to help shield the roof from UV exposure, weathering, and everyday wear.
As a licensed commercial roofing contractor, we follow strict installation standards to ensure fire resistance, structural integrity, and long-term performance. Careful control of material application and layer thickness helps deliver a roofing system that offers dependable protection for years to come.
