Modified bitumen roofing - SBS-modified and APP-modified asphalt in roll form - became the standard replacement for built-up roofing systems on San Antonio commercial buildings from roughly the late 1980s through the early 2000s. Downtown office and retail buildings that originally had coal-tar BUR often got their first reroof as a modified bitumen recover. The Riverwalk hotel corridor, the older commercial buildings along Commerce and Houston Streets, and the low-rise retail stock along San Pedro Avenue are dense with second- and third-generation mod-bit.
Commercial Roofers of San Antonio scopes modified bitumen systems for the buildings where mod-bit is still the right answer - and we say directly when it is not. There are downtown San Antonio buildings where the structural load capacity, the existing BUR substrate, and the project budget make a mod-bit recover the most defensible capital decision. There are others where the existing system has failed deeply enough that a single-ply tear-off and replacement is the right scope even if the initial cost is higher. We make that determination with moisture core data, not with assumptions.
