Sika's SolaRoof is a photovoltaic system designed for thermoplastic roofs that does not require penetrations in the roofing membrane in order to mount panels.

Bill Bellico, Sika Roofing's marketing director, said, "Having a lightweight system without the need for hundreds of penetrations in the roof is a game changer for the industry. Now building owners no longer need to worry about the risk of damage from the shifting of traditional ballasted arrays or potential leak threats from all the penetrations of a fastened system."

Sika says the key component is the Sika SolarClick welding flange, made with the same formulation as Sarnafil membranes, that are mounted to each support and hot-air welded to the Sarnafil membrane. According to the company, they provide a large contact area for uniform weight distribution and ease the loads on thermal insulation.

Sika includes the system in its roof warranty coverage.
