Does anybody know if it's OK or smart to vacuum out the vermiculite that is in our attic in the soffits/overhangs? It's an older house and it didn't have soffit venting or a roof ridge vent but we recently had new siding and a roof and ridge vent installed.
While doing the soffit/fascia job outside, the contractor drilled holes up through the old soffit boards, spilling out some of the vermiculite, before installing the new soffit venting system.
While in the attic, I started to vacuum out the overhangs but it's not a fun job and the bottom layer of the vermiculite is not loose. It's caked in and I have to dig it up with my fingers to vaccum it out. I was told that I may want to put the vermiculite back providing it doesn't plug up the newly drilled vent holes. Thank you.
