We live in the High Mojave Desert in a big, 2000ft, meditteranean style home with many elevation changes, bump outs, indents, soffits, etc. Over 20 yrs we have grumbled about drafts, excessive cold, excessive heat radiating from the ceilings. We have sealed or repaired what we could find. No one has spent time in the attic other than cable guys.
I finally went up yesterday, fully protected and spent several hours attempting to move around and understand how the insulation was put down, looked for air leaks & leaks from the heating/ac insulated tubing.
I didn't get far but did caulk around various light, fan and ventilation that I could find. The insulation is not laid out neatly at all. It is supposed to be R30 and it does look pretty hefty so suspect it likely is. I expected to see bats laid out w/the joists visible but there is nothing neat or orderly. It appears that bats were unrolled to a point and then poked at attempting to get it in place. It looks more like a yellow feather comforter has been laid down. There is also a thick layer of dust covering everything. I was wearing an N95 mask but still ended up coughing,& sneezing.
Can someone tell me if doing the attic inspection can be done by me with a list of tips, rules, etc or is this a professional only job. I was surprised that the attic was a comfortable temp, not cold, not hot and not at all drafty but we clearly have cold & hot areas especially our back wall that I can't find a way to get to. We also have cement tile roofing over plywood. Thank you for guidance to any info, personal or professional advice.
