Solar panels on slate roofs: safe and waterproof installation

Project featuring the ValkPitched solar panel mounting system on a slate roof
Ask a question about this product

Slate roofs are strong and long-lasting. Nevertheless, the installation of solar panels requires extra attention. 

Slates are vulnerable and can break with incorrect loading. The roof must also always remain watertight. With the right mounting system, you can install solar panels safely and reliably. 

What installers should pay attention to

When installing on slate roofs, you should pay attention to: 

  • Point load: distribute the pressure and prevent breakage  
  • Waterproofing: finish all connections well  
  • Substructure: always check the load-bearing capacity of the roof  
  • Asbestos: check on older roofs 

Reliable fastening for slate roofs

With this solution, you use the ValkAce+ slate tile roof hook, which you mount on the wood under the slates. For a waterproof finish, use the roof hook in combination with the SpeedFlash: 

  • Replaces one slate  
  • Ensures a neat and watertight connection  
  • Remains flexible in the face of temperature differences  

This is the standard and safe solution for slate roofs.  

Check the datasheet and manual of the Speedflash for more information.

  • No damage to slates due to mounting on construction  
  • Reliable waterproof solution with SpeedFlash  
  • Quick assembly with one tool (T30)  
  • Easy alignment of the system
