01
Separate who covers what
The quarry or supplier may address material, the installer workmanship, and a sheet-metal contractor certain details. Confirm responsibility for flashings, accessories and labor to remove and replace surrounding slate.
02
Read exclusions and notice requirements
Foot traffic, storm damage, building movement, maintenance, color variation and unauthorized repairs may affect coverage. Record inspection or notification deadlines.
03
Evaluate the warrantor
A long term has limited value if the company, product or installer cannot be located later. Keep contracts, samples, pallet labels and contact information with the building records.
