The first 3 are all as instructed for the first side of the valley, the final 2 are with the unique California cut second side, first shingle, running up the valley and set back 2' from the valley as in the instructions (I'll trim it curved to fit to the turret before installing). Their next step is to proceed with what most folks call California cut. These Tamko shingles are - so far - done by Tamko valley instructions. I have peel-and-stick in the valley and felt over the peel-and-stick. I'm redoing it and have a couple questions for you pros.īefore you tell me I'm doing this backwards, here's my reason: I would have shingled the cricket side first since it'll shed less water, but the curved turret and where the first shingle would have landed looked like trouble, so I've done the lower slope (higher volume)side first. Of course, it leaked! Location, VA and NC border with some heavy rains and up to 12' of snow.

Hi gang, a 'roofer' cut thru the underlayment while trimming shingles, nailed in the valley AND ended shingles in the valley.
