Shingle reroof: metal valleys yes or no?
I'm going to reroof my house with new 30 or 50 year arch. shingles. I've got a couple of areas where the roof lines intersect, about maybe 25 lineal feet total. One of the contractors that came out to give me a quote indicated that it's better not to install a metal valley since the nailed areas of the valley are an eventual source of water intrusion. He recommended doing a "california cut" where he would put triple underlayment in the valley area and overlap the shingles? I'm not so convinced that would be a better method to keep water from getting under the shingles. Which method is better?
