Hi anyone who knows how to replace roofing sheet in the right order.
I have 5 sheets accross and 2 sheets lenghth.

start bottom left, fix first sheet with 60mm overhang into gutter, fix with one screw, temporarily lay next sheet so that you can jiggle them square,then fix first sheet permanently. continue fixing eaves row, with say 2 corrugations overlap. next, fix the top row, with say 250mm head lap. it may pay you to bring your flashing along with your top row too.

Hi thanks for info. the roof is flat all but for a little drop from front to back.
i can visualise the first row on the back of the garage (lowest end) its interleaving the 2nd set that go to the front that is causing the problem
