Lead Rolls

Lead Rolls

Wakaflex® can be used as a flashing on “Lead” Rolls. This has to be used if two connecting roofs have different interlocking tiles (1).

Use a 50x50mm softwood batten which is screw fixed to the tiling battens.

The softwood batten is covered by a packing batten topped with a Wood roll. For sealing the “lead” roll use two strips of Wakaflex® with the butyl-strips parallel to it.

Choose a width of Wakaflex® to cover the whole wood roll and 150mm of the tile to one side. For profiled tiles the flashing should extend over the the first roll. Do not use Wakaflex® longer than 5m.

To lay the Wakaflex® start on the wood roll and fix it with clout nails. Form it completely along the “lead” roll and fix it on the tile side using the butyl-strips.

Use a roller to ensure a water tight join to the tiles. The second part starts from the roof side which is now covered with Wakaflex®. Fix it around the “lead” roll and end on the other side. Ensure that the second layer of Wakaflex® is laid tight and without crinkles on the first layer.

Additional fixing with nails is not neccesary due to the self welding effect of Wakaflex®. Finish the end of the “lead” roll with an additional piece of Wakaflex® ensuring a 30mm overlap.

When using cover flashings on flat interlocking tiles, a GRP Secret Gutter must also be used.

On Plain tiles this can be achieved with soakers (2).
