Roof leaking around vent pipe

Hi,



If there are any roofers reading this, I could certain use your expertise.



I had a new rolled roof install and it started to leak through one of the vent pipes at the first rain. The installer came back and covered the area around the vent with a black substance (tar probably?). This worked fine for a year but last night it started leaking again.



I have no problem with recoating this area once a year, but wonder if someone knows of a more permanent fix. I'm not calling back the installer and he's lost my buisness for good.



Thanks,



Bill

Google for "flashing." Sheet metal is the permanent fix to prevent weather gaps between the roof and vents and chimneys etc.

I believe if you look around you will find form fitting flashing units premade for this purpose. I suspect the rest of your roofing job is suspect too.

Thanks Art, I'll look into those fitted flashing units. I also believe you're correct that the rest of the roof is suspect and I have a new $8K bathroom sitting under another vent pipe 20 feet away. Thanks for reminding me of that very important point.

You don't say where you are located. Home Depot and the others have a soft lead flashing that fits over the vent pipe and lets you fold it over to go into the pipe. The base sits on the roof and is just sealed to the roof with roofing tar or similar.

See what they look like at

Match this flashing to the diameter of your vent pipes
