Fast forward to this spring. I am now trying to stop a leak i can’t find in the “improved pitch” porch section. See its better than it originally was but still not really enough. When we get enough rain, say 1/4 inch or more, we get water dripping inside in one spot. Not pouring in but say a couple quarts over the next day or so. Enough to be quite annoying and it needs to stop, becuz water will destroy things. It’s been dripping for a few years and slowly getting a little worse.
So i go up and hey! look! there’s a staple showing and another spot where a tab is a little broken. That must b it? Patch.
Next rain, replay. Hmmm. go back up and cannot really see any obvious issues. But there is a long valley where the porch roof meets my bedroom roof. Now i had checked in the attic to see if the wet was under the flashing. No, just above where the drip is. Makes sense, except when on the topside i cannot see any defects that would let water in. So next i seal the entire length of the flashing on the porch edge. The water must be getting in and traveling sideways right? More rain, more drip. Grrr.
So now i have been filling in the gaps between the shingle tabs. So far i have done this three more times in an ever widening area more or less centered on the suspect location. I stopped buying roof tar in the caulk tubes and bought a gallon container.
You can see here the long flashing, the suspect issues i started with, the center area where the fills look neat from the caulk tubes, and the widening area done with the putty knife and the gallon. Dang i hope this does the trick. I’ll keep you posted.
