Fastening Flashings
Flashings may be fastened in three ways:
- By primary fastening – fastening into the main structure.
- By secondary fastening — fastening into the cladding.
- By means of clips, cleats or seams to allow for differential movement of the roof cladding and the flashings.
It is recommended for flashings-to-roof cladding that at least one row of fasteners goes into the primary structure, and primary or secondary fasteners are applied close to all longitudinal edges.
For full details on fixings, see Fasteners.
