Roof overhang on cob barn conversion

Hi all, long time lurker, first time poster here.

I had a question for the cob building experts please if you would be so kind. Looking at purchasing a cob barn conversion (picture attached). This is in Cornwall in the UK (wet, windy, but generally mild).

The main thing that concerns me is the roof overhang - or lack of it! Is this going to pose much of a problem? The conversion is only a few years old, so I've no real no way of knowing if it's going to stay standing long-term!!

Any and all advice gratefully received.

Cheers,
Matt.

It may pay to track down people who do that sort of work or did that one.
In Australia we would have a large overhang, but Cob building is a very old art in your parts and they may have a trick up their sleeves
we dont know about.

I had a small building I put up a while back and it had minimal overhang of roof and had constant problems after several years with walls getting too much moisture and rotting and mold and all the rest. that's just my experience.

Thank you so much for your replies. I'm not sure we are going to proceed with the purchase for various reasons, not least the lack of roof overhang. If it's helpful for anybody else, I was advised by Kate from http://www.cobcourses.com/ that one option might be to put up some weatherboard across the uppermost section of wall - great idea I thought! Other option being to extend the overhang, of course.

Cheers,
Matt.
