01
Condition changes the risk
Thickness, texture, age, deck support, hidden cracks and temperature all affect how a slate responds. A piece that carries normal roof loads may still fracture under a concentrated heel or a twisting step.
02
Access is part of the work plan
Experienced slaters may use roof ladders, hooks, planks, lifts, scaffolding or other systems to distribute loads and reach details. The method should comply with safety requirements and protect both workers and the roof.
03
Keep unrelated trades off the field
Antenna, solar, chimney, gutter and mechanical work can cause damage when crews are unfamiliar with slate. Coordinate access with a slate professional and document condition before and after other trades enter the roof.
