Ok, so I have uploaded some pictures from the outside to give a better idea of what I am talking about. Here is a picture of where my two turrets will go to cover my biflolds and this side of my house positioned on the corner of my ground floor rear extension.

I was originally going to put the cables through the opening for the drain hopper with the turrets mounted on junction boxes but I am thinking maybe drill through to the flat roof. I don't want to compromise the water tightness of my flat roof though. Here is a picture from up on the roof.

After getting the cables on to the flat roof I was then planning on running them up behind the drain pipe then into the loft. At most I think the cable run will be obvious coming over the top of the flat roof and onto the drain pipe and then again back off the pipe and into the loft space. like below

Hopefully that gives a better idea of what I am planning to do. Any other suggestions would be really appreciated.
Cheers
