The original secret fix standing seam metal roofing system

The double interlocking ribs and clips ensure strength and watertight integrity. In the 40 years since inception SpeedDeck secret fix roofing has become a worldwide proven system that offers fast, simple installation, with excellent performance and design flexibility.

Secret fix standing seam built up systems have been used throughout the construction industry for many decades, maintaining a straight-forward to design, straight-forward to install principle to provide a continuous weathertight roof with no end laps. In addition there are no exposed pierce fixings, therefore creating a simple strong roof or façade system offering outstanding performance and total versatility.

With over 40 years of pedigree and experience the SpeedDeck® secret fix standing seam metal roof system continues to offer:

  • Outstanding performance
  • Walkable, slim, contemporary and ‘cutting edge’ solutions
  • Achieves straight, curved, barrel vaulted and waveform roof shape

Supplied in aluminium or steel with a vast range of colours and finishes, SpeedDeck® provides the perfect flexible solution for any designer with its ‘simple to design’ principle and for the contractor ‘simple to install’ ethos. With less perimeter components, slimmer verges, wider cover width and a simple clip system with no additional zipping up or mechanical seaming, the SpeedDeck® saves money and time and reduces the carbon footprint compared to any ‘Zip-Up’ standing seam system.

SpeedDeck® secret fix systems have been used extensively throughout the industry for many decades offering bespoke, lightweight, high quality, acoustic and quick to install roofing and cladding solutions to commercial, industrial, educational, PFI, MOD, Prison Service, PFI in the new build and refurbishment construction market sectors.
