In many cases air conditioner pipes that touch or lean against dryer vents can cause leakage in the latter appliance. A leak in a clothes dryer vent allows moist air from the dryer to enter the house. Dryerjacks are the first roof vents designed to meet the more stringent venting requirements of dryer exhaust systems. When your roof was installed each vent pipe received a flexible boot to seal water around the round surface of the vent pipe.

A leaking dryer vent increases moisture that can lead to mold growth. Stray lint and fabric may accumulate in the vent over time. Unfortunately the rubber boot damage often becomes the main cause of roof vent leaking. Vent pipe leaks during heavy rain can occur if you have cracks in your vent pipe boot or flashing.

The increased moisture can contribute to mold growth if ventilation is not adequate enough to prevent moisture buildup around the location of the leak. Use a screwdriver to release these so that you can vacuum. The leak is being caused by condensation that is forming either inside or outside of the actual clothes dryer vent pipe.

Sun exposure and heat especially during the summer can cause the rubber boot to crack creating the space for water to leak in. Unlike the vents shown above left the dryerjack affects airflow by less than 01 water column inches of pressure. Dryer pipe leaks often arise as the result of their proximity to water sources or condensation.
