Erv fresh air intake vent

BPortnoy1 | Posted in General Questions on

Hello. I have a Cedar shingle roof. I am not super happy with how this fresh air intake vent was done. See photo. I know asphalt roofs can give off lots of VOCS. Do you know if cedar roofs do as well? I can’t find a good way to move this to a wall.  Is there any way to improve this? Thanks

    I’m not sure about the cedar (other than cedar oil odor,) but there may be pollen, fallen leaves/leaf mold, etc that could accumulate in that area and be transported inside. This definitely will not work if you get snow in your location. Also, see the attached file. On the very first page they recommend not placing intakes on the roof. And on the second page they state that intakes must not be located within 10 feet above any paved surface or roof. Also, check the installation instructions for your ERV model to see if roof placement is mentioned. Is this a hip roof or a gable roof? If you have gables, can you put it through the gable? If not, can it be raised 10 feet above the roof? You may need to call the manufacturer of your ERV equipment for technical support if you can’t find another location.
