Pre coated plywood

[unclehefty]

I have an ancient shed where the roof was discombobulated by the recent 'puff's of wind and would like to replace the T&G boarding and roofing felt with a pre-coated sheeting. Is there such a thing and if where from?

My daughter had her shed built with "pre coated" As much use as a chocolate fire guard. Within a year I had to refelt with decent stuff.
