Attic insulation question....

[Irving]

Since you have the insulation out, it'd be easy to work on whatever you'd like to do.

I have the same tiny over hangs as you do, and only two soffit vents, both half clogged with paint. It'd be very simple to purchase some narrow floor registers and install them as soffit vents. Then, take some cardboard and staple it across the rafters on either side of the vents. Run the cardboard up about 12" higher than you plan on putting in your insulation. Then when you blow it in, you can just fill everything up to your hearts content as long as you don't go over the cardboard. Since you have gable vents, you could also invest in some type of solar fan and point the fan out of the gable vent. Then you're drawing cooler air from under the eave, out the gable, and will have airflow without it being "windy" in the attic.

I added more blown-in at my house and two other houses in the neighborhood last fall, and it's pretty easy to leave a gap between the fill and the roof where ever you want. I had the idea of doing exactly what I told you to do, but was too lazy to actually do it myself. Instead, where ever I could see sunlight from the eaves, I just filled as close to the roof as I could while still seeing sunlight.

Blow-in is cheaper than the Cellulose or whatever the gray stuff is. The gray stuff is supposed to be better than the fiberglass, but it's gray because it's just chopped up newspaper, supposedly.

New roof and a roof mounted solar powered fan are going on in the next few weeks.. Had not thought about mounting a fan at the gable but roof fan hopefully will accomplish same purpose as it supposedly is active based on temperature in attic.

The area behind the gutters is at most two inches and roof venting is being handled via gable and roof vents. So there are no soffit openings except the as yet incomplete caulking on the new Hardie Board. I know I am over thinking it I am just worried about how far and how much to push insulation over the wall headers and beyond close to the Hardie board.

As far as the insulation itself all I see in the stores for cellulose insulation is the batts and the blow in, are there rolls of cellulose insulation similar to the fiberglass rolls? I had planned on putting the fiberglass in as shown and then either blow over that some cellulose or the thicker cellulose batts on top of it to get to correct R value. I am not very inclined to do the blown in because I am also still dealing with electrical work up there.
