Abstract: A chimney covering comprises a flashing in the form of at least one metal sheet applicable in the same plane as a sloping roof and provided with a collar, a tubular jacket applicable around a chimney pot, and a tubular connecting piece mountable between the jacket and the collar in such a manner that the lower part of the connecting piece encloses at least parts of the collar while the lower part of the jacket encloses parts of the connecting piece. The jacket has an upper end extending at right angles to the longitudinal axis of the jacket while the lower end thereof is obliquely cut at an angle of about 45.degree.. The connecting piece has a first end extending at right angles to the longitudinal axis of the connecting piece while the opposite end thereof is obliquely cut at an angle of preferably 22.5.degree.. The connecting piece is adapted to be turned with the above-mentioned first end facing downwards for small roof slopes and with the above-mentioned second end facing downwards for large roof slopes.
