Sorry to read that, Bob, and I am crossing my fingers, that you can find a quick solution to fix it.... 🤞🙏

The qualities of the fabrics can be very different and "heavy duty" as characteristic is mainly for marketing.....

As above said - depends on the quality. In my eyes, a strong high quality poly fabric is much more durable than canvas.

I would like to read the opinion of @Pacific_Yurts about!

TS, I used 17 oz. treated canvas on my first yurts. There was zero structural integrity and no ability to shed water after 6 years of continuous exposure. It literally fell apart as I was pulling it off the roof. I likely described all that here in the last few years. In great detail. lol

So yeah this coming year I'll be making a new cover from another material.

BTW that white tarp was essentially the same low grade blue, brown, and silver tarps found at the big box stores. Just sayin.
