Logistics: hoists, sidewalks and permits
Working in Manhattan is mainly a logistics exercise. Materials arrive by truck on busy streets with limited stopping space, and hoisting may require sidewalk protection, a closed lane or a crane, each with permit conditions. Noise and work hours follow city rules and building policy.
Open-flame roofing methods are regulated, and many buildings prefer systems applied without torches. We ask early about access, elevator use and rooftop restrictions. A short conversation with the building superintendent before the visit often saves days later, and it makes the schedule more realistic.
Elevator rules and loading hours differ between buildings, so ask the superintendent early.
