Sorry if any confusion but the following pics are of the outside of our roof. I'm pretty sure they have run the rubber right under the tiles & the lantern is now at the correct height although as shadow on the pics it may not look like it. It does look messy as he came back out & put sealant on the top of the rubber incase this had expanded.The leak is directly below the bar shown here, no leaks anywhere else. As you can see the 2 end caps are missing- would this be of any significance? Thanks for your response btw not sure what you mean by a hot or cold roof ?
