TIA
I noticed this closed valley that just looked odd. I expect overlap of underlayment, flashing and shingles, but this was the only valley on the roof that looked raised like this. Attic is dry, roof 12yrs old. Located in the Seattle area.
Not an inspection, but a neighbors house.

Odds are that there is metal flashing in the valley and it was buckled when installed. I see it all the time. Some roofers just don’t give a crap how it looks when it is done. . . .

Yeah, looks like metal under the shingles. At least the bulge is roughly the distance off the valley that those flashings run. Looks like the sun is hitting the roof and magnifying the imperfection. Things on roofs can look a whole different depending on sunlight and wetness.

If there is metal under the shingles it would not reflect through the shingles, it’s a build up of underlying shingles like in the video.

Makes sense… but I have seen the edges of those metal valleys showing through in the right light. But I agree in this case it would be odd to put that metal under a closed valley.

The hump is on the lap side. The underlying lap, laminate shingles, and the angle of the sun exaggerates the effect. That’s my take.
