NSF/ANSI 347 Certificate

Multi-attribute labels

A single-ply roofing membrane product is certified to NSF/ANSI 347, a point-based multi-attribute sustainability assessment covering product design, product manufacturing, membrane durability, corporate governance, and innovation, at Conformant, Silver, Gold, or Platinum level.

You might see it written as: NSF/ANSI 347 · NSF ANSI 347 Certified · Sustainability Assessment for Single Ply Roofing Membranes · NSF 347 Certified · NSF/ANSI 347 Silver · NSF/ANSI 347 Gold · NSF/ANSI 347 Platinum

What it proves

A single-ply roofing membrane product is certified to NSF/ANSI 347, a point-based multi-attribute sustainability assessment covering product design, product manufacturing, membrane durability, corporate governance, and innovation, at Conformant, Silver, Gold, or Platinum level.

What it does not prove

  • Specific single-attribute claims (recycled content percentage, VOC emissions, carbon footprint) — those need their own evidence even if they earned points here.
  • Roofing system performance claims such as reflectivity ratings or wind uplift, which are covered by other programmes.
  • Claims for membrane products outside the certified product scope.

Expiry matters — check the certificate is current.

Point-based multi-attribute standard: two certified membranes can earn their points in very different ways, so the level alone hides the detail.

Follows the same pattern as NSF/ANSI 140 (carpet), 332 (resilient flooring), 336 (fabrics), and 342 (wallcoverings) — category-specific standards, not interchangeable.
