Just back from a trip to Germany and I noticed that many houses had steps up the roof slopes and in many cases a platform near the chimney. I thought perhaps they were for satellite TV fanatics but there were too many. I mentioned it to a German I was working with and he explained that they are essential if you have a fireplace or stove so that the chimney sweep can go up without damaging your roof and with minimum risk to himself to sweep the chimney. I asked why this isn't done from the bottom - but the concept seemed to be to ridiculous for him to comprehend. Chimneys are swept from the top!!! I also saw many roofs tiles with what appeared to be glazed pan tiles
- quite attractive.
