Just been on my roofing course provided by Catnic using Tata steel standing seam roof. Great one day course provided free of charge incl lunch. Full demo on how to set out and complete your roof and the tools you will need. I know @Barney12 has had an awful experience with Colourcoat Urban which uses the same product but since I found out Catnic are now supplying this product I cannot speak highly enough of the service they have provided so far.
Numerous queries over our roof design have all been answered almost immediately and the guy presenting the course said you can contact him with any questions. You get a very helpful installation booklet, T-shirt and a certificate to go on the wall when the house is finished.
