This past winter was one of the worst for condensation issues in Calgary’s attics.  The prolonged, deep cold spells exposed issues that caused extensive damage and frustration to homeowners and contractors alike.  IDEAL was called to dozens of projects each month this winter where each homeowner was experiencing the same thing: moisture sources in the Attic.  While the causes vary; from the building materials in place, proficiency of trades involved, design of the home & nature of how each homeowner used their home; one of the most common culprits was moisture sources in the attic.  Predominantly these moisture sources included bath fan vent hoses/pipes and clothes dryers that exhausted through the roof.

We have discussed the importance of properly insulated hoses/pipes that pass through the unconditioned attic spaces before.  In 2017 IDEAL moved our focus to the Gooseneck roof vent which exhausts these moisture sources out of the roof.  We now place a high importance on installing a quality gooseneck vent with a dedicated collar that allows for a more secure connection to the vent hose.  This increases the likelihood that moisture will vent out of the roof rather then expel into the Attic space and cause damage.

Whenever we do find examples of hoses like the one pictured below we absolutely must do something.  This hose is the wrong product for this application and in our experience will lead to problems.  It’s a simple fix while we are in the attic working and we can install the gooseneck at the same time to ensure proper venting.
