01
Preserve pre-loss and post-loss evidence
Collect prior photographs, maintenance records, weather data and images from every elevation. Mark damaged pieces on a roof plan and distinguish old repairs from recent impact.
02
Describe matching requirements
Replacement slate must be evaluated for size, thickness, color, texture and weathering. Document available sources and whether surrounding material can be repaired without excessive breakage.
03
Price the complete repair method
Include safe access, removal, substrate or flashing work, replacement fastening, protection and cleanup. A unit price for one shingle may omit the real scope of slate repair.
