Roof Valleys
Having a new roof put on and present roof has metal valleys for run off. Should I keep the metal valleys or have the new shingles act as valleys? Present metal ones are in good shape. Any comments appreciated. Thanks.

You dont say how old they are . I like metal valleys. Use the ones called a storm valley. that is like a W that way you have two wear lines down the valley. Water cant run under the other side. I would make sure that they are as good as you say. Or put new ones up there . The over lap shingles do work ok. So its back to you what looks do you want

I would go w/valleys. Much more effecient imo.
If your overlapping shingles act as the valley..and the roof faces north..and prone to moss, that could present another problem...- backed up valleys...
