Is that an asbestos roof to the higher side. That looks like something has washed up on it or if there was something in the air affecting it. I was involved in a place a few years back were the aluminum gutters rotted , it was close to a fertilizer bagging plant and the wind would blow the fertilizer dust on to the roof of it, then it would sit in the gutter & rotten it.
No it’s a tegral super 6 which has no effect on the pvc coating also there’s form of industrial emissions anywhere near by supplier is blaming a concrete plant 10km away 🙄🙄
Is the sheeting a known brand and stamped? It happened me on a sheeting I bought but it was the cheapest I could source at time so obviously a shoddy paint job. You get what you pay for as they say
The sheeting was purchased from a “reputable “ company and was top quality. It’s PVC coated not painted and also has a non drip membrane on the underside. I would not be questioning it’s longevity if I bought poor quality. Regarding the stamp it’s difficult to find a stamp on the non drip cladding
