In-O-Vate Technologies designed the DryerJack vent hood to vent the dryer through the roof.

In-O-Vate Technologies has added the DryerJack to complement its popular Dryerbox and Dryer-Ell product lines. The DryerJack is a vent hood designed specifically for venting the dryer through the roof, which complies with IMC 504.4 and IRC 1502.3 building codes. With a 25% larger opening, it claims to be three times more efficient than a standard 4-inch gooseneck roof vent when measuring backflow.
