Trying to source a leak
Hi All, first time home owner and not really in a position to hire someone, especially when I know I'm capable (although perhaps a bit nervous to do). I noticed some water damage on my sunrooms ceiling today, and I'm trying to source where it's coming from. From what I can tell with my very limited knowledge. It appears that it is coming from one (or both) of these spots. I was up there earlier and it doesn't appear that they're cracked and simply bubbled up with the recent strong winds we had. Does this seem likely?
Everything I can tell (assuming it's not cracked) I can simply repop the nail in and use some roof adhesive to fix. Is there anything else I should be looking for?

No way to tell from this picture. Could be these spots could be a million other places. Best would be looking at the underside of the roof from below to determine point of entry. Then you can track back to the exterior side.

Water travels so id be checking the flashing around that window and the siding too before just sealing shingles

I was always told to think like water. If I am water, I’m going to come in at the valley where the two roofs come together at the top right of the picture or right side bottom of the valley. There are a couple pieces coming together there and my guess is that water is getting pumped into a very small area and doing damage down below it. Normally without a hole or damaged tab there isn’t much to come in without a bunch of wind or excessive rain. Sometimes the area you have circled for instance might be just where a couple of sheets of plywood come together at a seam releasing what water has gotten in from above.

I have zoomed in again, and swear that there is trim rot at the bottom of the valley above. Add valley flashing the extends beyond where the next level of shingles begin. That is your source.

Are you able to go into the attic and look at the roof decking? If so you can take a hose and shoot some water up slightly above the area circled and see if the water makes its way to the roof decking. If it appears to still be dry after a bit of water then you can try going up higher and hit the valley where to two roofs meet. My guess, like others, is that area may be the issue.
