Expert Verdict Reviewed by the SuperArbor Pro Desk

Type 4 is the high-softening-point asphalt typically specified for higher-slope BUR decks, so verify that your roof slope and specification match a Type 4 equivalence before ordering. Keep the kettle within the recommended heating range to avoid damaging the asphalt and to maintain consistent interply adhesion. Order roughly by the project’s mopping rate per square, and stage cartons close to the work to minimize handling on hot rooftops.

Hot asphalt work is hazardous: use proper kettle-side PPE, watch flash point, and follow OSHA hot-work and fire-safety practices.
