Welcome to the bunnings Workshop community @rhone. It's great to have you join us and many thanks for your question.

 

The type of flashing you use is partly be determined by what type of roofing you are installing. Could you please advise if you are are using polycarbonate or steel and what profile it is. Also, do you have plans on what point you are starting the roofing? Will it be overhanging the gutter or set back from it?

@rhone,

 

I'd recommend sandwiching Suntuf Black Corrugated Foam Infill 4 Pack under the sheeting on top of that closest purlin to the gutter. I would also sandwich a piece of Suntuf 127 x 5 x 15cm Clear Corrugated Polycarbonate Wall Flashing on the purlin with the flashing dipping down into the gutter.

 

You just want to make sure that when there is a high wind that water doesn't get blown under either your sheeting or the roof tiles depending on which way it's coming from.
