Waterproofing weather vane pole

Installed a weather vane a few years ago for which I had to drill a hole through the ridge tiles on the roof and fix the pole onto the joists below.

So far, all good.

However, I have never managed to get it water proof. Every 6 months, I have to empty the bucket which I had to put underneath it. I have tried silicone, that thick gue for gutter repair etc but nothing has worked so far.

Really, I would have thought some sort of rubber ring around the bottom should sort it but not found anything suitable. The pole is about 1 cm diameter.

What would work here?
 
Mastic.( black gooey sh*t that roofers use to waterproof seams and vents on roofs. ) Don't get it on your hands or clothes, it's like treacle but a bit more stiff.
 
I used that mastic though (disposable gloves contained more of the stuff then the vane ...) , and as the ridge tile is concrete, it just does not see to want to bond with it properly.

Andy - The concept of a weather vane is to catch the wind, which generally is on top of a building :D

It is on one of the out buildings though, not on my main house.

That's what I was thinking of-putting it on top of a barn etc...thought it was on your house :oops:
 
Can you put a shroud around the bottom that will take the water away downslope, seal the top of the shroud and all around the bottom . That's how we did conduits etc that went through roofs.
 
Yes, that is what I was looking for. What sort of shroud are you talking about?
 
We used to get them from roofing supply shops, basically a tin tube with a wide flat base, sometimes angled to match the slope of the roof but lots of the roofs were flat . Think of a skinny tin of beans sitting on a square piece of flat tin. that's what they looked like. Different sizes for different jobs of course. We sealed underneath and filled the top with mastic, never any issues.
You could make one fairly easily if you are handy with tin snips and silicone sealant. (or have a friendly tinbasher in the neighbourhood) Check the roofing dept of the local DIY shop...

after all that , if you still have a leak, it's probably coming down the inside of the pipe somehow.
 
Thanks for that, will have a look at a DIY place.

The pipe is solid through the roof, the weather vane is sitting over that pipe (with bearings), so the water must just run off the solid pipe through the concrete tile.
 
it occurs to me that a weather vane would have some movement caused by the wind ( doh!). that's possibly why you had problems with bonding to the concrete. I would definitely try the shroud ..... :thumbsup:
 
Bitumen Flashing ( flashband ) might work its a kind of tape with one side metal the other bitumen
Think there's two types one heated with a blowtorch the other self adhesive

Yep I'm not a builder but I was thinking Lead flashing.
 
Would this work?
