The SikaRoof® Anchor System is a prefabricated universal connection point for attaching photovoltaic systems to flat roofs.

Key Benefits

  • Waterproof Anchoring
    SikaRoof® anchors are welded into the membrane and then tied directly to the structural deck, keeping waterproofing intact while providing strong fixing points. 
  • Adaptable to Slopes 
    An integrated system supports flat roofs up to mild pitched surfaces and pitched roof designs when paired with appropriate K2 variants (e.g. SingleRail IFP).

 

  • Lightweight Design
    No ballast required: weight of PV and mounting remains low (~12–15 kg/m²), and no heavy ballast blocks are needed — beneficial for roofs with strict load limits.
  • Modular and Flexible 
    One anchor can support multiple panels (≈6 modules), enabling modular layout with fewer penetrations.
  • Planning Tools
    Integration with K2 Base planning software streamlines statics, layout, and design for the combined anchor and mounting solution.

Where it Fits Best

Projects needing strong, sealed and load-calculated anchor points
Roofs with slight slope where ballast solutions are suboptimal
Installations (flat or pitched) where modular system flexibility is needed

How Does it Work

The SikaRoof® Anchor System can be integrated with solar roof systems in two principal ways, depending on the rooftop photovoltaic configuration. It can be combined with the Solar Hybrid K2 Dome 6 Xpress or Classic systems using SikaRoof® Anchors, or with lifted parallel installations using the K2 SingleRail IFP system together with SikaRoof® Anchors.

This is how you can plan and calculate your solar roof using K2 Base together with the SikaRoof® anchoring system.

K2 Base features a dashboard for efficient project management, with Google Maps integration and graphic drawing tools that support the planning and calculation of your specific solar roof system in combination with SikaRoof® Anchors.

In just five steps, you can determine the optimal design of your K2 mounting system and configure your solar roof system.
