How much fastening of roof tiles to the subroof is necessary?

Both outermost rows of tiles around the whole roof as well as tiles around inlets/outlets, skylights, chimneys, etc. must always be fastened. Use Benders’ stainless steel nails, screws or clips. Where a roof is particularly exposed to weather, the use of clips is even recommended for Palema. Bender Exklusiv can only be fastened with clips.

With roof pitches over 45° and where there is particular exposure to weather, fastening must be more frequent (every 5th tile). With pitches steeper than 55°, all roof tiles must be fastened.
