Start with a commercial roof survey
A survey documents the roof areas, system types, apparent age, drainage, penetrations, walls, perimeter, patches, and signs of moisture. Interior leak locations and maintenance history add context. On large roofs, repeated leak points may follow expansion joints, drainage patterns, rooftop equipment, or traffic routes rather than one isolated defect.
Access is part of the survey. Ladders, roof hatches, locked areas, power lines, loading zones, and occupied spaces affect how work can be completed safely. Clear access planning also helps the owner understand where materials, dumpsters, and crew movement may temporarily affect the property.
Roof inventory
Separate sections may have different ages, materials, warranties, and replacement schedules.
Leak history
Dates, weather conditions, interior locations, and past repairs help reveal patterns.
Rooftop equipment
Curbs, lines, supports, condensate, and service traffic all affect membrane details.
Drainage
Drains, scuppers, gutters, overflow routes, and ponding areas are mapped before work is proposed.
