My roof-chimney junction is a disaster. How can I address the water issue?
We moved in 10 years ago. When we first moved in, after a heavy rain we noticed that water was running off the roof, against and down the chimney, and down the siding.
After a few years, we noticed some rot on the siding. We hired a handyman company, they replaced the siding and installed a cricket. This solved the water runoff issue, and all seemed fine for a bit.
2 years later, I notice in another heavy rain that a wet spot was forming inside our living room, on the wall where it joins the ceiling. It was probably leaking for a while, but it wasn't till then that it actually broke through. It looks like in the cricket repair, somehow a hole was created (or was always there, but not a problem when the water was diverting in the other direction, down the chimney) that allowed water to infiltrate inside. We went through the first roofing company, and after several visits, including reshingling the suspect area and "building the roofline to divert water the other way" (???), the problem wasn't solved.
We went through the second company, who restored the interior of the house, removed the original roofer's attempts, and fixed the leak. BUT, now the water drainage issue returned and water drains off the chimney again. Guy installed a diverter or two, didn't work, and then ghosted us. Husband tried installing an additional diverter, but the chimney drainage issue is still happening.
- Any suggestions for what we can do? Do we install a gutter? Is there a better way to install anything to help with the drainage?
- Our neighbors have the same house design and they don't have this issue.
- I know before we bought the house that the roof was redone (there was a massive hail storm), and there was some suggestion by another neighbor that a tree may have fallen and "hit" the house (not enough to require permitted repair or an insurance claim, beyond roof repair), so I'm wondering if the new roof wasn't pitched right. How would we test that?
