We live in the high desert of Southern California and our home is positioned facing South and the prevailing winds blow from the West. Our gable vent faces West and over time the sand has blown into the attic.

I assume I'll just shop vac it up, but how do I prevent this from continuing to happen while keeping the much needed ventilation??

Thanks in advance!

  • Sand from the Sahara desert - lots - blows into the Bahamas and is the number one source for land additions in the region. You are dealing with something in your own back yard, not a full ocean away. That being said... Good luck with your attic!

  • Can you provide a photo, or sketch, to show the construction of the "gable vent". Not everybody understand that term, who might be able to offer help.

  • What kind of roof? Can you switch to ridge vent?

    I think the likely approach here would be to baffle the vent so that the incoming air is slowed to the point that sand drops out, while still outside the house. Basically an open bottom box over the vent...or offset boards if bottom up is a problem (vent is exhausting - but seems like it's mostly intake in prevailing winds.) You'll probably have to experiment to get dimensions that work.
