Roofing felt or other sheet material is located between the flange which embrace and provide a seal for the sheet material. At the interconnections of the roof joints, there are arranged junction sealing elements having, like the longitudinal sealing elements, channel parts and adjacent side flange, the channel parts of the junction elements extending at right-angles are to another so as to correspond to the joint interconnections.
