Quote:That pre-moulded flashing from Screwfix looks good, but it's quite expensive and there doesn't appear to be one for the clear corrugated sheet.
On the subject of lead flashing, is it easy to shape to fit onto the corrugated sheet?
I was surprised at how expensive it is but it is for a particular product and you may find alternative products at much lower prices.
Lead is not easy to dress and I don't know how much of a beating your plastic sheeting will take before you damage it.
Lead and self-adhesive flashing are not clear either
