Dektite® Diverter

For Hi/Low Roof Pitches

No ponding or damming! The large base of the Dektite® Diverter dramatically reduces and diverts rain water back up that can occur on very low or high pitched roofs and deep ribbed roofing profiles. No need to cut around pipes, just quick straight lines for the square base.

Two edges of the Dektite Diverter feature our classic Dektite Aluminium strip, whilst the remaining edges are left bare to enable you to cut the width of the flashing to fit your application. Two additional Aluminium strips are supplied to cover the remaining two edges of the flashing, fix with self-tapping screws & silicone.
