Without proper airflow, premature shingle deuteriation as well as roofing failure are extremely likely. In the winter, moist warm air created by every day activities like cooking, cleaning, and heating can rise into the attic. Without a continuous flow of outside air, the water vapor cannot exit. This trapped water vapor and interior generated moisture are unable to escape which leads to wood rot, mold, mildew, and wet insulation. Along with these problems, trapped warm air can condense on the underside of the roof deck resulting in even more moisture issues.

In colder climates, the attic is usually warmer than outside temps causing snow on the roof to melt. This melted snow travels down to the gutter, where it refreezes, creating an ice dam. This causes all types of leaks and damages to shingles, gutters, insulation, and the overall roof system.
