3m Clear Stormproof Corrugated Roof Sheet Porch Lean-to Corrapol Roofing

Nicely surprised. better than expected. thank you.

...you'll have to work out how to make the sheets fit exactly onto your roof (they're actually very stretchy, but if you go mad they won't 'agree' with the polyethylene foam draught/support strips which are definitely NOT stretchy), and the instructions from Corrapol (Clear Amber) show you how to start with the aluminium edge pieces first, and you'll end with putting on the aluminium ridge.I've just done a DIY project and have to say the instructions leave a lot to for the user to work out, the drawings in the instruction sheet are not detailed. For instance, a gold tip is to realise that when fitting the roof sheets you'll be better off 1. not fixing the sheets along the top, but you won't want to leave your new roof like this for long, the corrugated sheets are very strong but incredibly flexible and fly away easily even in a moderate breeze 2. have a ridge piece ready to hand to fix along the top of the roof BETWEEN the edge pieces at each end of the roof. This will give you the easiest fix and best look. Good luck with sealing the join at the top of the edge pieces, though! Good luck also with cutting 1. the corrugated sheet (they recommend a jigsaw - joking - nightmare - ended up using mini angle grinder with diamond disc, noisy, clean cut, loads of not very nice dust) 2. the aluminium edge pieces and ridge. For the latter I 'happened' to have a cross cut circular saw for which I had already bought a special aluminium cutting blade (Trend is the make, you'll need to buy their big bar of wax lubricant, too, all available here on Amazon).Essentially technically the components (poycarbonate Stormproof sheet) and the aluminium edges and ridge are great. How you put the whole lot together, I'd say Clear Amber (the manufacturer) haven't worked out in proper detail. I ended up with the ridge going over the aluminium edges, but the messing around trimming away to get a 'best fit'... mad. And the roof is not stormproof. My ridge is sailing slightly high and I'll be using clear mastic to complement the foam weather strips (mentioned above) to stop rain driving in during storms.
