I gutted the bathroom right down to the studs and since then i have noticed that when it rains especially a wind driven rain i am having wet OSB sheathing at the top plate on my upstairs bathroom wall. It sporadically is in every other wall cavity at the top and we our puzzled as to how this is getting wet. We have checked inside the attic , we have checked the gutter to see if they are blocked. I have had two roofing companies come by and one of them took this picture, its quite small so hopefully you can make it out. I noticed this gap in the gutter on the corner, however they have said this would not cause an issue. The only thing thats left would be to install a drip edge. Could anyone suggest any other possible causes that might have been over looked. The roof is only 13 yrs old and shingles apparently doing well. Thankyou for any advice.

A roof without a drip Edge AND ice and water shield is not done correctly or to code. Also does the sheathing overhang the top of the fascia board?
Apparently no drip edge was installed when the house was built in 2007, I was told it wasnt code back then. So looks like i will have one installed with the new shingles. Thankyou for your reply, appreciate it.
Drip edge and Ice and Water Shield has been best practice for a long time. Any roofer who would leave either out, code or not, is not worth hiring. It has been code around here [PA} for at least 20 years. No need for a new roof for 13 year old shingles, any competent roofer can remove shingles, apply the drip edge and ice and water shield and then re -apply the old shingles.
More and bigger photos would be helpful.
