The picture shows someone adding insulation to walls which is what I needed to know but the video shows someone adding insulation to a ceiling!

If you put that 2nd layer of insulation between roof rafters instead of laid on the existing ceiling insulation it will help to prevent the heat from entering your attic. It will help especially for houses with a/c and heat units in the attic bc the unit will not be overworked.

I am in Texas, I am using faced insulation batts on a closet wall. My question is where should the paper facing? facing exterior or facing interior or doesn't matter which side? Please advise

Can you add batting over existing blown in insulation? If so, which one to use faced or unfaced?

So what if I have old colonial where the roof meets the wall line at a gutter with almost no overhang. Does that mean I dont have soffits? I have gables at each end no ridge roof vent. But when its dark in attic I see faint bit of light from the edges/eaves

Adding vents, but I didn't see any opening to the outside.
