Self-Induced Attic Diversion

Never mentioned this before, but after I added all the insulation to the attic above the garage, the garage become nice and cool during the start of the summer, but the rest of the house became unbearably hot. It was actually quite impressive how much hotter the house was than the previous year. On one day the air conditioner couldn't get the house lower than 78 degrees, which it never had an issue obtaining before. After some contemplation, I determined that the attic no longer had an adequate source for incoming air. Having plenty of roof vents which the previous owner had added, and a roof fan (obviously a hint there were issues before), there was plenty of places for the air to exit the attic. Problem was, there were never any inputs, apart from the garage. When I finished insulating the garage attic space, I noticed when standing on the ladder into the attic access, with the garage door and window open, the air rushed past me up into the attic. The attic access was the only place for the incoming air to flow into the attic. I'd suspected this was an issue previously, so I then began the task of cutting in soffit vents in the eaves around the entire house. To complement this, I also added plastic rafter vents to ensure the air flowed into the attic unobstructed. No pictures of that, as it was tough enough setting them in place while stapling them to the underside of the roof.

Long explanation, but here's a look at the work in progress.

What the eaves looked like before the vents.

Cutting into and soffit vents installed.

I placed a vent every other rafter which I thought should be plenty. Turned out to work quite well, as there was a noticeable difference after the installation. I increased the roof fan to kick on after it hits 110 degrees in the attic instead of 100, and it only kicks on now during the hottest days (95+ degrees outside).
