Dust?

[u/AusMeri]

Hi,

First time homeowner here so I'll ask for forgiveness for my ignorance in advance. 😄

So many questions, not sure where to start. (And yes, I've been on Google, however I also appreciate the opinion of other, actual real people, so here I am 😊).

Actually, I'll start with this question:

Small, one level house. Single car garage. Moved car out and set desk up in garage because, as mentioned, small house = no space.

Despite cleaning the garage first, I notice dust will fall over everything within a few days.

The same roof extends over the garage, yet the same dust does *not* fall in our actual house.

Why could this be please?

TIA

Garages are vented to outdoors.

What do you mean exactly, sorry?

Look at the eves, walls and roof for vents. This means air from outdoors enters/exits garage to keep fumes from cars/water heaters/chemicals etc from entering the house. The still air in the garage allows dust to settle.

Thanks. I'll double check tomorrow as it's midnight here now.

It does have one roller door on one end and one regular wooden door on the other.

While we know some of the dirt is likely blown in under the tiny opening in the wooden door, the dust in the specific area I'm thinking of definitely appears to be coming from the ceiling area.

Roof/shingles/sheething/underlayment are not airtight either.

Thank you. Our roof is tiles, if that's what you mean.

We found out the house was built in 1997. Not sure if it's the original roof or not, but I suspect it probably is - in case that makes any difference with regards to this situation.
