When a dormer on a tile roof is covered with zinc, first the valley gutters are placed along the sides of the dormer. These gutters will be connected to the existing standard gutter.
The façade cladding at the sides of the dormer are secured with clips to the wooden substructure. The standard standing seam system is preferred as cladding system. For small surfaces there is also the option to use flat sheets connected to each other using singles welts. These single welts also contain clips for fixation to the wooden substructure. The clips must allow adequate expansion of the zinc sheets, to prevent bulging.
Joints and connections should always have sufficient space to guarantee the thermal movement of the zinc. Especially with this kind of application it is advisable to check the assembly of the coverings prior to soldering, clipping or seaming to prevent problems due to the thermal effects. Only then it is possible to create a watertight cladding.
