We have a standing-seam roof on a brand new home that's presenting a serious water-infiltration problem somewhere around the valleys of a rather large cricket that's situated between two converging roof planes. All roof pitches are 2 in 12 (including those of the cricket) and the valeys themselves are about 10' long. The entire surface under the the metal is covered with ice and water shield, with the exception of a ridge vent on the cricket. Thinking the vent itself could be the culprit, my roofer fabricated extensions for the vent to eliminate any possible infiltration by run off or splashback--but to no avail. Are ridge vents prone to leaking in this situation? Is it a viable option to eliminate the ridge vent in favor of some sort of scoop or pancake vent down on the roof plane? Or is it more likely that a valley seam (or other) was not properly sealed? My roofer claims to have done an identical application for a house right on the ocean that is experiencing no problems, yet our leak is a regular result of even moderate showers. Thanks for any help you can give. (We also have regular leaking around a plumbing vent pipe. But that's almost a non-story by comparison.)

If you wish, send me photos and I will try to diagnose. My email is [email protected]
Have you contacted the roofing manufacturer to see if they can help?
Generally, making ridge vents work at a 2:12 pitch is a problem.
