Diagram 1 shows a typical bonding gutter detail using a lead lined drainage channel at the junction between the two roof coverings. For situations where the bonding gutter is to be used over a fire break party wall the underlay and tiling battens must be terminated either side of the mortar bed fire stop. Turn underlay over timber tilt battens either side of bonding gutter. Bonding gutter with metal lining ensure that gutter board is wide enough to provide full support for ends of tile battens tilt battens and the valley lining.

This can be formed from lead or be a manufactured pre formed product. Description depending on the tiles or slates being used our bonding gutters are available in high or low profiles. The detail can be formed using preformed polymer based products traditional lead work or more modern lead replacement flashings. High profile ma40471 is suitable for profiled concrete tiles either on one or both sides.

It is quick and easy to install in all weather conditions and provides a neat finish. To ensure that the tiles adjacent to the redland dry bonding gutter lie in an even and level plane it is important to follow the construction details in this section. For example between a double lapped plain tile and a single lapped large format interlocking tile. The correct way to weather the junction is to install some form of gutter or channel between the different tiling.
