Select a Scope That Can Be Maintained
Repair, recover, and replacement have different prerequisites. A patch addresses a limited defect; recover adds a new assembly over a suitable, dry, attached roof; removal exposes concealed layers and deck conditions. We inspect attachment, moisture, drainage, existing layers, and project requirements, then describe what supports each path. A recover-versus-removal review can put the owner’s options in the same decision record.
For replacement, the estimate identifies membrane or metal, insulation, cover board, attachment, edge securement, flashings, drain details, staging, and allowances for concealed conditions. Timing and cost depend on removal depth, deck repair, equipment coordination, access, delivery, waste handling, and weather. A commercial replacement scope lists those drivers so managers can compare a repair with a planned capital project.
After work, maintenance can revisit drains, seams, flashings, and equipment curbs. Its purpose is to track observed conditions across the assembly and record the repair history, not to assume that every property on the corridor has the same roof or needs the same interval.
