Roff ridges are placed on top of the roof panel seams. They are available in the respective panel colors . They follow the panel step and are suitable for trapezoidal panels or tile-imitation panels.

The combs are placed on the free ends of the panels to protect the polyurethane from the weather, but for aesthetic reasons too. There are bolts in the colour of the panels and all special fittings required to complete the construction are also available.
