InOvate DryerJack 4" Low-Profile Dryer Roof Vent

Stop Lint Buildup and Airflow Restrictions at the Roof

The InOvate DryerJack 477 is a low-profile roof termination engineered specifically for 4-inch dryer exhaust systems. Its curved damper, large exhaust opening, and low-profile hood are designed to minimize airflow restriction while providing a durable, weather-resistant roof termination.

Venting a dryer through the roof can help shorten the total duct run in certain installations. The DryerJack provides a purpose-built alternative to conventional roof vents that may restrict airflow or use screens that are not permitted for dryer exhaust applications.

Code Compliance

According to InOvate's current DryerJack technical documentation, the DryerJack 477 complies with IMC 504.4 and IRC 1502.3 requirements applicable to dryer exhaust terminations. Always verify applicable local code requirements and installation requirements for your project.

Dryer Venting Through the Roof

A properly designed roof termination is particularly important for dryer exhaust because excessive restriction can reduce airflow and contribute to lint accumulation. The DryerJack is engineered specifically for this application, using a curved damper and unrestricted opening rather than a screen at the termination.

For installation dimensions and requirements, refer to the manufacturer's installation and specification documents.
