Sealing brick

Okay. I understand now.

In your business, do you do brick work? I know in some states roofers do it all including windows and siding. Around here, after determining that the flashing isn't the cause, I would give the homeowner the number of a good mason.>>>

Sorry, but I don't have any advice. I do have questions though. Does this brick chimney absorb enough water to manifest itself inside the building? (Obviously, you've ruled out the flashing and mortar joints.)

I'm having difficulty conceptualizing a roof leak caused by brick soaking up water. Is the source of the water snow piled high on the roof?

Sorry HOP, I mite have not explained the problem deep enough.

The roof is not leaking , the water is running down the face of the chimney. In one place it is coming out of the brick face below the ceiling level, kind of like a wet weather spring, if you know what I mean.

Cracks are not out of the question here. This house is approx. 30 yrs old. Some settling has occurred, but not causing any major cracks. It is a split level , with a chimney coming up between the levels, with a brick wall veneered on both sides of the chimney. Last year we tore out all old flashing and replaced with new,still leaked. We went back and spraysealed with siloxane as far as we could reach,still leaked. We went back and took a tarp , and wrapped the top of the chimney, where flues come out, this stopped 90% of the leak. We are going to go back and put a metal cap on the chimney, but I wanted to seal the brick the rest of the way up, I thought there mite be another sealer out there to use, that mite be better than siloxane.>>>
