Is BUR still a good choice for commercial buildings?
Yes, BUR remains excellent for certain applications. Its multi-layer design provides redundancy, the gravel surface protects against UV and foot traffic, and it has a 100+ year track record. For large flat roofs, BUR offers proven long-term performance.
