My builder and I finally snapped and we decided to build a temporary roof here. I hate wasting time and resources on something that is not the final solution - but enough was enough. The temporary roof will protect the building and it is cleverly a couple of feet above the original roof. so we can eventually construct the proper replacement underneath in the dry.
The photos show the step-by-step construction of the roof. My builder has achieved an amazing quality of build, and has chased it exceptionally neatly into the contours of the building. He assures me it will last for decades, which made me laugh. And certainly, it buys genuine time for the building. :-)
