During the recent heavy rain in Southern CA, our office warehouse
experienced some leaks that seem to coming down around a small pipe
that runs up through the roof. I went up on the roof today and noticed
that the tar around the copper pipe seems to be cracking and lifting
up. Can someone recommend a product to easily patch it? I have
enclosed 2 pictures of the area and the pipe of interest. The
photo-1.jpg picture clearly shows the tar lifting up on the lower
right corner of the copper pipe.

More than a brand of tar, you need to fix the leak with flashing of
some sort. The tar is secondary to the mechanical fix.

I went through this with our warehouse. We got some tar repair whose name I
no longer recall but it was a silvery colour with black streaks when you
stirred it. Medium thin stuff so it soaks in fairly well.

Go to a good roofing supply company - don't use the cheap stuff from the
retailers.

The old patching you have looks terrible from point of view of leaking. You
should try to remove as much of it as you can, including that felt. The
felt looks as though it wasn't completely soaked through with tar. The
repair stuff may leak through the opening around the pipe so be carefull -
maybe get some new felt and soak it well and then cram it around the pipe
so the liquid won't run along the pipe. Use a lot of the repair stuff in
several layers. Takes about 5 or 10 minutes between layers.

Your problem occurred because the tar dried out and cracked either from
shrinkage or from being too stiff to flex as needed. You can keep the new
repair from drying out by sticking on a layer of cloth or plastic that is
UV resistant. The roofing supply company should have something you could
use. In a pinch a piece of the same roofing sheet that is on the roof could
do but it would be too stiff to work with easily. Something more flexible
would follow the surface of the repair and keep the sun off.

Now that I think of it - get the diameter of the pipe and ask the roofer
for a collar with a skirt that would be clamped around the pipe and tarred
down around the perimiter. That would look professional.

Hi, does anyone have a photo or a website that can show me how it
should have been done? It is a good learning experience for me.
The original install was done by the builder of our office building
about 5 years ago.

If it is 5 years old and leaks, speak to the builder. Do you own or
rent this building? Any warranty from the builder?

Bulldog WetStik if you can still get it in California.
It is a fibrated plastic roofing cement that will stick to wet
surfaces.

Nobody else said it, so I will- the preformed doohickeys they sell for
sealing a membrane roof around the hardpoints for a roof deck should
work for that. Cousin to the self-stick ice membrane stuff, just precut
and shaped for a deck penetration. I'd cut back the failed thing around
the hole, and use some emery cloth on the pipe.

Put yeah, that was a ****ant way to run a drain through the roof.
Whenever HVAC cycles, or it gets sunny, that copper is gonna move
around. Around here, they usually run those through the parapet wall on
backside of building, then down, staying outside the heated envelope,
and not penetrating the roof.

It needs a rubber boot installed. Oatey makes a few kinds.

The pics got me wondering if the copper pipe running through the roof
is a hack job of some sort that needs correction?

If I get a rubber boot, can I install the boot above the existing tar
without having to tear everything up? Do I just apply the cement
around the new flashing?
Does the rubber boot create a waterproof seal around the copper pipe
without having to use any chalking or tar?

Thanks

I wonder how I am going to install a rubber boot since there is a
horizontal copper pipe connected to the vertical copper pipe.... I
can't slide the new rubber boot over the copper pipe and down to the
roof surface.

Find a split one that wraps around, with a seam that you can glue or
something. Or since most boots in stock will be for larger pipe anyway,
slit a larger one. Same material you glue it to the roof with should
work for the seam. I'd look for a self-adhesive boot, and once it is
down, paint over it with some sort of sealant that will flow into the
cracks. Next time they have to fuss with those roof units, I'd look for
some other path to route that drain.

You should carve away the lumpy parts, to get a good mating surface for
the new boot. Since that pipe moves relative to the roof, I'd look for a
boot with ridges at the top, perhaps even one you can put a hose clamp
around. It needs to be able to flex a little as the pipe moves on sunny
days, or when the HVAC hardware vibrates.

Slit the boot. Make a ventral slit, axial to the
central orifice. Local anaesthetic, and prepare
glue tray for readhesion of avulsed material.
Scalpel!
