01
Document the pattern and direction
Photograph representative slopes, elevations, metal damage, debris and interior evidence. Note whether breaks cluster on exposed planes or appear throughout sheltered areas. Preserve dates, weather records and prior-condition photographs when available.
02
Use access methods that avoid new damage
An aggressive inspection can create fresh breaks and confuse the evidence. Qualified slate professionals should choose ladders, lifts, staging or roof-access methods appropriate to the building and slate condition.
03
Match the repair to the actual damage
Localized impact may support individual replacement, while widespread damage can require a larger plan. Matching slate thickness, size and appearance matters, as do affected flashings, snow guards and accessories. Insurance scope should not dictate a technically incomplete repair.
