I contacted oregon yurtworks about the roof leaking issues. We shopped around for the most honest roofer we could find and He did fixes that they spelled out.

These fixes cost us about 1500 and while they stopped some of the issues the leaks came back along several hip roof areas that winter

The following year the roof leaked even worse and we had to do a complete tearoff and replace. several of the plywood underlayment and 2x4 beams were rotten and had to be replaced. The roofer estimated that the roof had been leaking since year 3-4 after the build. This is on the 30 year roof upgrade that yurtworks offers.

Since the reroof, the house has been dry weathertight and no staining, leaking or other issues.

the yurtworks fix $1500 or so.

The roofer fix about $5500-6000.

total spent $7000 or so out of pocket

calls to yurtworks about some sort of settlement just came to nothing.

I am also interested in building and Oregon Yurtworks yurt building....how did your research process go? What have you found out about the structures? Is this roof/condensation problem a common or isolated situation.
I would appreciate any information you have. Thanks

Any updates to your situation?

Would you suggest purchasing one of these structures? Any other disadvantages/ problems?

We had extensive repairs done on the roof last summer based on the new owner's recommended procedure. That seems to have stopped the leaking problem. The original builder did the work and did an excellent job.

A sour taste remains because of the company's refusal to stand behind its earlier products. From an earlier post here it appears that the former owner is still a minority owner of the "new" firm, which adds to the disenchantment. The yurt itself is lovely and comfortable. Don't underestimate the costs, though, of building out and finishing the interior of circular spaces.
