Hello
I am in the process of planning my own installation and want to make sure I have everything sorted before I begin.
Please can anyone advise the best method of waterproofing where the flexi pipework passes through the pitched roof?
Thanks in advance

Happy to send you photos of how I did this using lead flashing with integral waterproof grommet . Fix flashing neatly over chosen tile. Drill tile on the ridge with suitable holesaw (marley tiles are very easy to drill). Bring the pipe through the felt.  Mastic around the flexi pipe and the tile (keeps any drafts out and back up waterproofing only) Stuff some fibreglass insulation in the void under the grommet fitting. Then fit the rubber grommet over the pipe and clip the securing ring in place. Neat, tidy and waterproof forever. PM me if you want images.

 Fit & fix, a little bit of cost & a lot of peace of mind.
