Persistent Leak - Chimney or Roof?


no, not during normal winter weather, even a normal winter rain storm, dry snowstorm, melting snow, I have had no issues. Only during long drawn out soakers. The bricks seems to just absorb the water like a sponge and then drip out of the mortar. as the rain continues, more and more bricks below start to get soaked with water

Just frustrating because my first instinct was that it was the flashing, but I have had that repaired plus a cricket on the back end of the chimney installed.
Also, this a built in fireplace chimney but shares the stack with my furnace and hot water heater exhast. Separate flu for the appliances and fireplace has not been used in 2 years.

Persistent Leak - Chimney or Roof?


Has a RILEM test been performed on the brick to determine permeability?

Persistent Leak - Chimney or Roof?


The chances of your chimney joints(Mortar) all leaking to create the 360 moisture pattern around your chimney might be comparable to winning the lotto.If your chimney (inner) is leaking from the inside out then why does it have a moisture pattern consistent with the outline of the chimney.If it was leaking from the inside out you would see broken,cracked mortar and possibly a few missing bricks. Your problem could be 1 of 4 things including all 4 at once.
1. Counter Flashing is worn out.
2. Apron (front) and the pan (back) are worn out
3. Mortar joints where CF was installed has lost its sealant
4.Your home is always shifting/moving sometimes overnailing an apron or pan will assist the CF with pulling itself away from the chimney leaving exposed joint.

Before you go and do the "Goop n Smear" have a few contractors give you an estimate for replacing these items mentioned NEVER let a contractor think that you are not savvy to the situation because I know a couple here that will give a list of problems that would rattle your mind.The bad thing about chimney leaks is it only gets worse. Good Luck

This is the obvious problem, I agree. This is why I had all of the flashing re-done along with a cricket in the rear of the chimney as noted with previous posts by a roofing company. They were very confident I would not be getting any leaks because of the new flashing.

My guess would be that it could be the mortar joints where the lead flashing is installed. The roofers did not touch this part. This might explain why only with long drawn out storms, water starts to seep in?

Step-flashing is individual pieces of aluminum that are installed over each shingle butted against the chimney,this flashing(step) is installed behind the counter flashing.The counter-flashing is imbedded in the mortar joints,this is what I feel your issue pertains to.I will try to upload a pic for you.,The pic will show some flimsy aluminum embedded within the joints.The pic is from a reroof I did and the chimney pic is a before pic of the new counter flashing install.

For some reason the pic isn't loading so I will post it in my album, just click on my username and follow to my albums.

I think you might be right. I went back up on my roof to get rid of some of the 2 feet of snow I had before the next snow/rain storm and took a look at the mortar joints. There is at least 2 areas where a gap has formed between the counter flashing and the mortar. It looks like the mortar just pulled away over time creating this gap. Probably a couple of millimeters wide along the whole length where the counter flashing goes into the mortar. The counter flashing is installed into the mortar but it looks as though if it rained enough, enough water might seep/drip into this gap, thus creating my seepage. This area is above the exact area where the water is seeping down. Further up the roof/chimney line, there are no gaps. The joints seem to be sealed well and I dont have water seepage entering from these areas. This is the only thing I can think of. Does this make sense to you?
I checked your site for the pictures, and they were not there. Also the roofers re-did my step flashing as well when they were up there. I will see if I can get a picture next time I am up on my roof.

Wow, that does look bad. My chimney has the lead counter flashing and looks very good where it meets the house. I am beginning to think that my issue is where the lead flashing is embedded in the mortar. There is definitely some spots where water could make its way into the brick. whether this is the problem or not, I guess I will find out if I have these spots repaired. 2 foot of snow on my roof is preventing me from getting up there to get some pictures. Thanks for the pictures.

We usually flash them before the shingles go over the back pan.

Can we see the 'after' pic?

I install the pan before theroof completion but this was a hail job and we were really behind.I was about 5-7 Counter jobs behind. I caught up and I have yet to get a finished photo.,the reason for that is the longer you wait the shingles seal a little better.I love roofing but I really,really,reallylove Counter flashing.It is a metal mans craft, I use crimpers,snips,and a brake. All of my jobs are made by hand....NO KITS HERE!!!!!!!!!!!!!!!!! I will post some pics. thanks for asking.

skenn8,

I really appreciate your keeping us current on your progress, and I'll be very interested to to learn the cause of your leak once it's finally established.
