DECRA by IKO Metal Roofing has been protecting homes and other buildings with unparalleled durability and style for nearly 70 years. But you may not know that DECRA has a fascinating origin story that dates back to the World War II Blitz of the United Kingdom.
DECRA’s earliest version stems from efforts to protect vital structures during the bombings. This innovative roofing material has evolved since then under different names and formulations.
In this blog, we tell the story of how DECRA came to be, including:
DECRA continues to stand the test of time, protecting homes across North America. Read on to learn how it got its start in the 1940s and why that was crucial to the durability it still offers in 2026.
During the bombing raids over the UK in World War II, many of the country’s major cities were devastated for months. You’re probably aware that London was repeatedly hit, but other English cities like Liverpool, Birmingham, and Sheffield were targeted, as well as Cardiff in Wales, Glasgow in Scotland, and Belfast in Northern Ireland.
People lived for years behind blackout curtains. Those who weren’t evacuated built shelters in their yards or took refuge in Tube stations underground. The Blitz became a life-changing event for British residents because of its widespread devastation of infrastructure.
Many crucial buildings were damaged or destroyed and needed to be rebuilt as quickly as possible. Because of the urgency of the situation, whatever materials were available were put to use.
One of the most common rebuilding elements was corrugated metal panels. But they came with a problem: they were highly reflective, which made them easy targets for the Axis Powers, who lit up cities before dropping their payloads.
The Allied Command needed a non-reflective coating to defend against this. And it had to be durable and easily produced despite wartime shortages. Decraspray Co. came to the rescue. The chemists at this bituminous emulsion manufacturer developed a groundbreaking coating that offered two benefits. First, it successfully shielded buildings from air raids. And it also resisted the harsh climate of Great Britain, which combined heavy rain with salt air from the sea.
In fact, the Decraspray coating was so effective that it was nearly impossible to remove after the war. This drew the attention of developers and contractors across Europe who wanted the same long-term approach to building protection in their countries. Eventually, it also caught the eye of Lou Fisher, a New Zealand entrepreneur. He acquired the rights to manufacture the coating outside the UK and trademarked it in 1955 as Decramastic.
Fisher’s contribution to DECRA’s development was adding crushed stone granules to the material, which prevented roof panels from sticking together and also enhanced their appearance. With this change, stone-coated metal roofing was introduced to the residential market, laying the foundation for DECRA Metal Roofing today.
DECRA Metal Roofing was officially trademarked in 1978. By this time, several decades of innovations added to its durability, aesthetics, and installation method, including its signature interlocking panel system.
In the 1980s, though, DECRA really accelerated in popularity. A prime catalyst was the surge of catastrophic wildfires in California, which resulted in a ban on traditional shake roofing. DECRA’s noncombustible stone coating was an ideal solution for homeowners seeking fire-resistant roofing alternatives. DECRA metal roofing provided a level of protection against fire that other traditional materials couldn’t match. Soon, DECRA was known nationwide, especially as the frequency and intensity of wildfires continued to rise across the West and beyond.
With drought and brush fires now a common concern even in regions like the Northeast, fire resistance is no longer a problem only for Western property owners. Underwriters Laboratories (UL) is an independent organization that tests home and construction products. It has awarded DECRA the highest fire rating possible. Homeowners everywhere in the US enjoy the peace of mind that comes from knowing their roof resists combustion and stays in place during fires originating outside the home.
Homeowners don’t have to sacrifice curb appeal to capitalize on DECRA’s exceptional safety performance. It comes in a variety of profiles and attractive hues that replicate traditional roofing materials, such as shingles, shakes, and tiles. You can match a DECRA product to any style of home and any paint color, as well as brick, stone, and stucco.
