Our commercial crews have installed both built-up roofing and modified bitumen on Essex County buildings for decades. Here is what years of field experience reveal about these traditional flat roofing systems.
Installation Realities
BUR installation is messy, time-consuming, and generates strong odors from hot asphalt kettles. In Essex County's dense commercial areas, neighboring businesses and residents often complain about BUR installation fumes. Modified bitumen installation is cleaner, particularly with self-adhered or cold-applied products that eliminate hot asphalt entirely.
Torch-applied modified bitumen requires fire safety precautions but is still less disruptive than BUR hot mopping. For Essex County buildings in close proximity to others, modified bitumen's cleaner installation process often determines the choice regardless of performance preferences.
Repair and Maintenance Observations
BUR repairs are straightforward: cut out the damaged area, install new plies, and flood with hot or cold asphalt. The repair integrates seamlessly with the existing system. Modified bitumen repairs are similarly straightforward using torch-applied or self-adhered patch material.
We observe that BUR roofs develop leaks more gradually, with water migrating between plies before appearing as an interior drip. This migration makes leak source identification more difficult and expensive. Modified bitumen leaks are typically more direct, making source identification easier and repairs more precisely targeted.
Our Current Recommendations
For new construction, we recommend modified bitumen over BUR for most Essex County commercial projects. The installation is faster, less disruptive, and produces comparable durability. Modified bitumen also integrates better with modern insulation systems and recovery board products.
We still install BUR when clients specifically request it, when replacing an existing BUR roof section that must match, or when the absolute maximum puncture resistance is required. BUR's multi-ply construction remains unmatched for foot traffic durability.
Modified bitumen has largely replaced BUR as our default recommendation for Essex County commercial flat roofs. BUR remains the specialist choice for maximum puncture resistance and the most demanding commercial environments.
