Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 3A40BC tri-class unit is the right all-around choice for roofing work because it covers solvents and torch-adjacent fuels as well as ordinary combustibles and energized tools. Mount it in an accessible, unobstructed spot in the work truck and check the gauge monthly. Have it recharged after every use, even a brief one, and keep up with the tag inspection cycle.
Use extinguishers only on small incipient fires; keep your exit at your back, evacuate if the fire grows, and follow the annual professional inspection and recharge requirements.
