The verge on the roof

All areas of the roof have names like eaves or ridge. The verge forms the end of the roof on the roof. In particular, due to the more stringent EnEV requirements (Energy Saving Ordinance), the verge has again moved more into the focus of homeowners. In the following we explain the verge to you, as well as what it has to do with the EnEV.

Location of the verge on the roof

The front end on the roof is called the verge. This extends on one end of the roof from the outer point of the eaves overhang to the ridge and then on the other half of the roof back down to the outer point of the eaves overhang. Due to the different roof constructions, not every roof has a verge. Typical roof shapes with verges are the following.

  • Also read - Protected verge: The wind bar on the roof
  • Also read - roof box - rounds off the roof and protects
  • Read also - The Gable
  • Gable roof
  • Crooked hip roof
  • Barrel and arch roof
  • Monopitch roof

The hipped roof, on the other hand, has no verge. The front, small roof areas are drawn to the eaves in this roof shape, which is why the verge is not required.

The importance of the verge

On the one hand, the verge is a constant when calculating the roof, so it is required by structural engineers, architects and roofers. But it also represents the end of the roof, where several materials meet.

  • Roof skin
  • Roof truss
  • Gable (gable wall, facade)

The verge as the weak point of the roof structure

The verge thus represents a weak point in the roof structure where moisture and moisture can penetrate. But thermal loads can also lead to different expansion of the different materials and thus result in leaks.

The cladding of the verge is primarily protection

That is why the verge is also protected. On the one hand, this can be done with special battens, which are often decorated. In conventional residential houses, however, the verge roof stone or verge stone is more common today. These are special roof tiles or. Roof tiles that are pulled down to the side to protect the verge against the weather. Most verge stones extend 40 to 50 mm above the verge.

The verge and the EnEV

The Energy Saving Ordinance also prescribes an improvement in facade insulation under certain conditions. As a rule, composite thermal insulation systems (ETICS) are used for this purpose. However, they are several centimeters thick. Therefore, the verge often has to be extended when installing an ETICS, otherwise the ETICS cannot close properly.

Extending the verge

But extending the verge is a difficult undertaking, depending on the design of the roof structure. Up to three rafters are to be exposed and then a purlin extension is to be carried out, for example by lamination. However, this means additional weight, which is why extending the verge is not always easy. Especially in connection with the EnEV, the verge plays an important role for homeowners.

Tips & Tricks The designation "Ortgang " is made up of the old German words "Ort " for tip or degree and "Gang " for activity, field of activity. The verge means the end of the accessible roof area.
