[quote=Anonymous]You definitely need to correct this. The question of how to vent it outside the envelope is one where you need to balance two issues: 1) length of the duct, 2) location and ease of maintenance.

Ideally, you'd never vent through the roof because it is difficult to access the vent termination and clean it. Yet, if there is a long run to get to a wall or gable end, it may be better to run to a roof vent. You might also be able to vent out and down through the soffit (and if it is near a window then you can open the window to access the vent and clean it).

DO NOT allow anyone to install flexible hose as it will cause you more trouble than it's worth. Note that ducts running in your attic--usually an unconditioned attic--run into big issues with internal condensation. If they are effective at removing the warm, moist air, that air can condense in a cold pipe running through the attic. Dust, hair, lint, etc. will cling to the duct work and build up. So make sure it is galvanized or aluminum rigid pipe and make sure it gets insulated and sealed with the proper duct tape (not "duck tape" or the gray stuff but actual duct tape an HVAC installer would use).
