The Story of the Original Stone-Coated Metal Roof

DECRA Metal Roofing products are manufactured at our state-of-the-art facility in California but our proprietary stone-coating manufacturing process has an illustrious history that dates back to World War II.

An emulsion coating derived from road tar and stone chips was first developed by the Decraspray Company in wartime England to camouflage the reflective corrugated metal roofs of important storage buildings and protect them from German air raids. After the war, the DECRA coating had bonded so well that it was virtually unremovable from the underlying corrugated iron. The coated metal roofs were so well-preserved that many began to see the incredible potential for creating a new standard of durable roofing products.

The original DECRA formula has been improved with an advanced acrylic base which has set the gold standard for durability and longevity.


Sophistication and style were introduced to the metal roofing sector with DECRA’s proprietary stone-coating method. When added to steel, which is the perfect substrate for stamping in a variety of shapes, stone-coating allowed DECRA to exquisitely replicate shingle, shake, and tile, with the unsurpassed longevity that only stone-coated steel can provide.


In 2009 DECRA completed the rigorous requirements to register to ISO 14001:2004, an achievement which highlights our commitment to environmental responsibility in both manufacturing processes and the sustainability of our roofing products. DECRA is a proud member of the United States Green Building Council, and a prominent LEED contributor.
