Leaks around chimney after new roof was put on


Any idea how much the sealer should cost me?

I personally thought that the problem was with the new flashings as the roof never leaked before this new roof was put on, but they assured me that's not the problem.

Thanks for taking the time to write.

Thanks, Ed, for those links for the sealer.

To recap: I have to have some work done on my chimney: (1) tuck point it and (2) a lot of the mortar replaced on the outside blocks on the top part of the chimney about 8 rows up from the top. This is to repair the leaking coming into the house down both sides of the brick fireplace walls. They also recommended that I have it sealed. Question: Should the sealing be done right after this masonry work is done, or should it wait a few months after this repair work is done in order to allow time for the mortar to cure?

I can't recall what is recommended by the Masonry books I have read right now, but if it is dry and warm weather, I would wait at least 48 hours if that is a concern.

Now I have to look something else up, just to be certain that the advice is accurate.

you need to wait longer,cement takes a very long time to dry,anywhere from 45-60 days would be more accurate,so moisture doesn`t affect any sealers applied

I'm glad you reminded me to look that up. I will check out my masonry books when I get to the office later this afternoon.

Thanks. I do not recall them saying to wait that long, but I will find out.

What would you recommend my using to fix the staining on the interior brick walls that the rain caused? The mortar has stained quite a bit (white and yellow).

10% sulfuric acid and 90% water.

Have PLENTY of ventilation.

Rough bristle brush to rub the stains with.

Safety goggles for your eyes.

Cover everyting that can possibly be splattered with a very heavy rubber tarp material.

Try just soap and hot water first though, plus that will show you how much splatter there wil be.

I actually think you should repost this portion of the question in the masonry section, especially for safety reasons.

Thanks, Ed, for the quick reply. I think I'll try the soap and water first as you recommended, seeing that that's less invasive than sulfuric acid. But if I needed to buy sulfuric acid, where would I get the stuff.

Someone mentioned using vinegar. Do you think that would work?

Home Deopt sells Sulfuric acid.

Try anything else first. Vinegar, ammonia, clorox, 409, Simple Green, Fantastic, etc...

The masons should have the best advice on this part.

Hopefully it's the flashings and it will be covered under warranty. If it is the mortar, about how much would that cost if done by the roofer? Or is it something that I could do myself? I do have half a bag of mortar that the roofers left because when the roofers came out and installed the new roof, we needed a new chimney cap.
I hope your roofer mixed some of that acrylic stuff with his mortar as new mortar does not stick to old very well without it. You can repoint your own chimney & it could be that the counter flashings were loose & installing new roofdeck flashings were enough movement to create a problem. Also lots of roofers try to wrap the flashings around your chimney or skylights or don't know the proper way to snip then fold the sides with a 3" overhang.
