Week 21 - A lot of contractors would have been due back this week, but as the next stage is the lower level roof, which had been delayed just before Xmas due to rain, the same would have happened for a large part of this week. Didn't visit this week, so not sure if anything occurred late in the week when the rain stopped.
Only good thing about the rain in the last few weeks, the builder can't class the days as rain days and add them to the contracted period as they are already classed as the shutdown period.
