Roofing Slate Quality Assurance

 

Quality assurance (QA) is a management process that addresses the critical control points in delivering slate for mountain to market. Quality management is documented and compliance with all the steps along the way to deliver product to specification is audited to ensure 100% compliance. Independent auditors are used to ensure company integrity.

Slate is not just about good raw material it is also about how diligently a company processes the slate and the care it takes in checking quality.

ISO 90001:2000 is generally regarded as the most rigorous QA standard in the world (refer to www.iso.org). The top roofing slate producers embrace quality assurance programs.

Buying slate from companies without independently audited quality assurance programs is a risk not worth taking.
