Before you start fixing roof sheeting, you should do a couple of checks. Check the roof for square. Check it for parallel. if it has a bit of a variation from the ridge to the eaves the ridge flashing will take care of that, but at least be aware of it. If you are working on a gable roof and the gables seem out of parallel, be aware of it. Polycarbonate screws will pre-cut a hole wide enough to allow for this expansion, which will prevent the sheets from buckling. The large rubber on the screw will also seal on the sheet and stop any water from penetrating the roof. It’s important that your fixings go through the crest of the corrugations on your sheet.
