SikaRoof® Anchor

The SikaRoof® Anchor creates a universal connection point for fixing roof mounted products such as the Sika® SolarRoof PV Mounting Systems to exposed Sarnafil®, Sikaplan®, SikaShield® and Sikalastic® roof waterproofing membranes.

Metal Mounting Rails Installed on Flat Rooftop Surface

The SikaRoof® Anchor system for FPO or PVC roof waterproofing systems opens a broad field of solar application on roofs. It creates a secure and watertight connection point from the roof waterproofing system to the solar roof system. Sika recommends the solar mounting systems from K2.

  • High performing fastening system
    Fully secured against movement and wind-uplift forces in all climate conditions
  • Fast and efficient Solar Roof System Installation
    Approximately one SikaRoof® Anchor needed per 2.5 kWp (around six solar panels per 2 m2)
  • Fully modular solar roof system


The specification for the quantities and positioning of the SikaRoof® Anchor points are calculated by the solar designer / installer.  This is based on the size of the solar panels, possible snow load and the project-specific substructure with the defined distances.
