ice dams can be prevented without ventilation if you use the right insulation and are very careful about the detailing of the insulation work. Quality assurance is key to preventing moisture build-up in an unvented roof. We have installed, hundreds of unvented roof applications, including some on Cape Cod, and have not had any failures.

Good luck with your project.
