What would be the best method to add flashing around an electrical service mast that goes through a 3in12 shingled roof? It isn’t possible to slip a new boot/flashing over it (the wires are in the way…).
The electricians slipped a neoprene boot ONLY over it when it was installed, the boot just sits on top of the shingles.
I have seen retrofit boots that clamp around pipes, but they seem to be for flat roof use only.
Also, there is a large screw eye in the roof attached to aircraft cable supporting the mast. What to do about this?
How should I proceed? Any advice would be most welcome.
