California cut valleys make for a great closed cut valley, however we have an installation trick to improve performance in areas of high winds, snow or rain. In addition, this installation tip will improve the performance of roof installers.

Please check with local code and the manufacturer to make sure that it meets their requirements. We know for certain that it will pass our local code and that Certainteed, OC and GAF allow for the installation of this valley, however you must not install on a slope less than 4/12 for GAF installs. Please consult with your manufacturers representative before installing this valley.
