A composite roof tile manufactured from mineral reinforced, 99% recycled and re-engineered materials, manufactured to create the same aesthetic qualities as natural slate.

IKO Slate Crown Ridge Slates are also available to finish the roof. Having the same slate surface patterning as the regular IKO Slate, they have a flexible centre portion which allows them to be readily formed to the ridge profile.

IKO has a range of essential system components, specifically tailored to facilitate the use of the IKO Slate system within pitched roofing. The following represents the system components available as part of that range:

  • IKO Armourvent Multi/ Multi Plus - a profiled ventilation strip for use at the ridge position in a ventilated pitched roof arrangement.
  • IKO Flash (available separately) - a lead-free flashing system, which is a mixture of modified bitumen and additives reinforced with an aluminium mesh.
  • IKO Stickall Mastic - a bituminous mastic sealant, typically used for the pointing of lead-free flashings.

Features and benefits:

  • Lightweight - around 80% lighter than a traditional slate of the same size.
  • Ease of use - integral spacer nibs to assist with setting out the slates and can be cut with a fine-toothed handsaw.
  • Convenience - easy to carry packs with unique carry handle straps to make loading and off-loading as convenient as possible.
  • Strength - resistant to breakages, making it easier to handle and install.
  • Robust - resistant to fungicidal and microbial growth as well as airborne chemicals and pollutants.
  • Fire performance - carries an S AA fire rating under BS 476-3.
  • Service life: In excess of 20 years.


IKO Slates are satisfactory for use as a roof covering on conventional ventilated and unventilated pitched roofs with a rafter pitch of 22.5° and over. The ridge detailing utilizes the system specific IKO Slate Crown Ridge. On ventilated roof configurations, the system can utilise IKO Armourvent Ridge Ventilation Strips.
