Continuing the ‘Things that we Find’ theme, look at this photo. This is a photo of a bathroom fan vent that vents into the attic instead of venting to the outside of the home. If you have fans in your bathrooms, you must occasionally look into your attic to make sure your vents have not come loose and venting into the attic. The bathroom fan vent must vent to the outside of the home. If the vent goes into the attic, it increase the moisture and humidity in the attic and over time will cause damage to the roof structure and the decking. In this picture you can see that the decking has started to deteriorate and this will lead to deck failure and could lead to mold in the attic. Double check these at https://casabathroomware.com.au.
