Cambrian Slate Info & Repair

Cambrian Interlocking Slate

Cambrian slates are thin, single-skinned, interlocked top and sides and fixed with nails and metal clips. They are exceedingly difficult to replace. Replacing a broken slate due to careless feet/knees or poor installation technique may involve substantial stripping of the remaining slates or referring to the Redland repair system.

Download our guide below for more information and the Redland guide to repairing damaged slates.

Vertical Rail Mounting 'L' Bracket

Solar Limpets L Bracket - Slate (Zoomed)

The Solar Limpet metal 'L' bracket adapts the Limpet adjustable bracket (on Tile or Slate installations) to enable the use of rails mounted top to bottom, required for some landscape panel orientation options.

Fixing Screw Lengths

Solar Limpets screws

Solar Limpets provides a range of screw lengths from 40mm to 200mm. Longer lengths up to 260mm may be available on application.

The standard-length screw fixing supplied for rafter fixings on tile and slate will be 115mm.

If the roof has been counter-battened, the minimum screw length recommended would be 130mm, depending on the thickness of the counter-batten used.

For overlaid insulated warm roofs, longer sizes will be required depending on both the thickness of the installation and counter battens.

For further advice regarding application to other suitable roofing surfaces, commercial and domestic, contact Solar Limpets technical support (Carl Reynolds 07968 231145).

Adjustable Bracket and Rail Fitting

Solar Limpets are suitable for side-fix type rails only.

Adjustable bracket fitting and recommended tightening procedure. The rail connecting bolts should be sourced from your rail supplier to match your chosen rail. When fixing the rail to the adjustable bracket, tighten until the nut bites, and then another half to one-third turn is sufficient. DO NOT OVERTIGHTEN.
