Replacing Corrugated Plastic Roof

[HumanAstronomer3194]

The clear plastic sheet (even if it doesn't look clear anymore) has holes in it and I put duck tape on until the weather improved last year. Now I'm looking to replace it and I'm wondering is there anything I should take into consideration before starting this? Even the fixings. Should I try and reuse the old ones or go out and get new ones https://www.screwfix.ie/search?search=+Pan+Roofing+Screws

It's a relatively simple "old sheets off, new sheets on" kind of job but definately use new fixings. Screwfix do these and Wickes also stock similar...
