How to inspect a roofing slate delivery

Problems are easier to solve while material is still organized on the ground. Every delivery should be checked against the approved submittal and purchase description.

01

Verify identity and paperwork

Confirm quarry or producer, product name, size, thickness, quantity, pallet markings and applicable reports. Similar color names do not prove that a shipment matches the approved source.

02

Open representative pallets

Inspect material from several containers, not only the top of one pallet. Compare thickness, dimensions, surface, edge character, hole placement, color range and visible defects with approved samples.

03

Document shortages and damage

Photograph pallet condition, labels and representative pieces before material is distributed. Separate freight damage from production variation and notify the responsible parties promptly.
