There is some staining on the underside of my roof sheething near where some flashing was repaired some time ago, when I use a moister meter to measure the unstained area it reads 11 percent, when I measure the stianed area it reads from 14 to 17 percent. I took these readings after a period of about 4 days of rain totaling about 4 inches.
It seems pretty obvious to me that if there was still a leak the moisture meter would have much higher readings.
My question is…. is it possible that the staining is giving a higher reading do to some physical alteration allowing more conductivity?
Thank is advance!!

How bout some more condensation (surface moisture) from warm house air and colder surface? Condensation stain v. leak?

No, there was definitely a repaired leak some time ago (years) to the flashing on the chimney. So, I'm confident it is not condensation that caused the staining. I'm wondering if the staining could have effected the conductivity of the wood? This would explain the slight difference in readings from stained to un-stained area's. Any other idea's?
OK, here you go. Maybe when the leak occured, the ply swelled and when dried out, didn't return to it's original tight grained state. Now, being a bit more opened up, it attracts and absorbs that much more moisture. __________________________________________
