Bonding Gutter Detail

Philip dalton explains what bonding gutter is and how it works.

Bonding gutter detail.

For example between a double lapped plain tile and a single lapped large format interlocking tile. A bonding gutter refers to a detail which weathers the vertical junction between different roof coverings. This can be formed from lead or be a manufactured pre formed product. Diagram 1 shows a typical bonding gutter detail using a lead lined drainage channel at the junction between the two roof coverings.

The correct way to weather the junction is to install some form of gutter or channel between the different tiling. Turn underlay over timber tilt battens either side of bonding gutter. 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. 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. 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.
