@Adam A. No grooves but it has ridges https://share.google/QdMFMNRacWdkKCIxp Like in that link
@Adam A. In fairness the guy who did it has done literally hundreds of them so it’s not really that. It’s prone to moss and a nightmare to maintain without access to it, I’ve seen a few with the box ridge profile and it seems much tougher and easier to maintain without all the grooves
@nicky F , that is unusual, I’ve done a few of these myself, including my own and I don’t have this issue, could be a case that the installation on yours might not have been done right, or the overlapping might not be as tight as it should be
@Adam A. That’s what’s on it at the moment it’s a disaster, moss between the overlapping and can’t get up to clean it without cracking a sheet
You’re best bet is going with the corrugated pvc, do you have the dimensions of the roof you are looking to replace, the sheets are available in most places like woodies/bnq etc
@Adam A. Haven’t done it yet Adam kinda lookin for someone to supply and fit the Perspex which would mean measuring and cutting to length etc . Have the existing one cleaned up and its grand just a pain to clean as moss gets between the overlaps and stuff
@Domagoj B. No thanks
@Domagoj B. lol no thanks
Hi Adam I’m struggling to find the box profile polycarbonate I need locally at the moment
Hi Nicky yes I can take sheets away the screws that are already there probably no good a box of them screws are about €10 and you will get around 50 you can get bigger boxes with 100 the more the better it's up to you
@Joseph B. Hi Joe I meant to include this will require removal of existing sheets they’re screwed in not disposal obviously
Hi Nicky when you get the Perspex sheets screws and roof flashing tape 9 inch I can come and do this job for IV done a few you can see in my reviews
