Well they do look nice with all these Christmas lights & rope lights on these property roof and what concern me is how are they putting them up safety without the person fixing them falling off the roof ? Are they using roof ladder, cherry picker, body harness or are they risking their safety ? I've seen one in the newspaper with loads of rope lights from one chimney along the ridge tiles to the other end of the chimney, did the person walk along the ridge tiles to fix this ? Have any of your neighbour's done this, if so, how did they do it ?
