Permavent Easy Slate

SKU
Permavent Easy Slate

Easy Slate is a side lap strip that works by sealing the perp join on the slate and prevents the water from entering the layers of the slates. It works by extending the head lap from the tail of the upper slate to the head of the slate below. For example, a 500x250mm slate with a 100mm lap will now have a sealed perp join and an effective head lap of 300mm.


One of the reasons slates fail at low roof pitches is the water ingress by capillary action between the layers of the slates. When using easy slate the slates are raised by 1mm which allows the free movement of air below the slates.


By increasing the headlap and removing the capillary action, the weather resistance of the roof is greatly improved and slates can now be installed on many complicated, exposed or low pitched roofs.

  • Available in  precut lengths of 500mm and 600mm, or 3m uncut.
  • Enables any slate to be installed in roof pitches as low as 12 degrees.
  • Improves the weatherproofing of slates
  • Eliminates wind slate rattle
  • Does not affect the aesthetics of the roof
  • Quick and easy to install using traditional methods
  • Offers a cost and weight saving when lowering the roof pitch
