how to flash around an existing electric service mast?

FlyNaked

I have to put flashing around an existing, and hot, electric service mast. How do you, the professionals, do it? The last roofers didn't do it and it leaked and has cause a few thousand in damages.

I was thinking about slicing a thermoplastic 3" flashing boot laterally and placing it around the mast and appropriately putting it under the 3 tab shingles. Then I would nail it to the roof and THROUGHLY seal all cuts with black silicone II.

Does anyone have a better technique?

Thanks in advance.

That would work, but clamp off the top part of the boot that goes around the pipe with something like a radiator hose clamp.

Also, there is a product out there now, called Spin Boot or something like that.

Here, I found it for you.

Look it up on there website for a distributor near you.

Thank you very much. The Spin-Flashing might just do the trick. :-)

There is a boot made just for that now, it is a residential retrofit flashing www.goldenrulefasteners.com You can't buy from Golden Rule Fasteners unless you are a supply store, but they can tell you where to pick one up. ABC Supply stocks them though, I do know that.
