Roof leak
Posted: Fri Aug 28, 2015 3:44 pm
Specifically, I think it is the vent stack which is directly above where I have a small hole in my upstairs bathroom ceiling, and where water dripped out during a particularly bad storm.
Here is the hole. Here are some telephoto shots of the suspected offending vent stack: And the lower one which has the same "fix" applied to it, but is not currently known to leak: I got a quote from a guy who has done work for Bill and he wanted to rip the singles down to the sheathing and "do it right" for about $300. But the more we talked about it, the more he seemed to be suggesting that $300 was a minimum price, unaffected by my offering to throw away scrap (which he originally cited as one of his costs) as well as offer some leftover shingles for my roof (which he also said wouldn't lower the price). This roof is on its second layer, and this second layer is a 20 year Certainteed, on year 20. No reason to go overkill on the vent stack sealing at this point since it will need to be redone when I do a roof. That may happen within the next 5 years.
This product seems extremely promising:

I need to measure but I am guessing the upper vent is a 2" and the lower one is a 3". That is cheap and reviews seem positive.
If I want to go nuts, I could double seal it and put something over the old gasket before putting the Perma-Boot on. But I may just slap a Perma-Boot over what is up there. Probably should do both.
The trouble is, this rear roof section is extremely steep. I measured it at a 9/12. You cannot walk on it. Support is required. So once I figure out how to safely get up there and work, I will do this.
