How to reduce heat on our 2nd floor
We have lived in our house for a year, and we're finding the second floor (an addition done in the 1930s we think) is just a heat trap. Conversely, it's quite cold in the winter, too. (We need to insulate some of our downstairs windows, etc, but the windows upstairs are double-pane relatively new...)
I'm very ignorant about house stuff, and so I was wondering if others have suggestions for how to address this. We need to eventually update our roof (it's old), and I suspect the insulation in our very shallow attic above the bedrooms is pretty haphazard at best (it's hard to see the attic -- though we had some electrical work done and got a glimpse). Ceiling fans are an obvious first step (though our ceilings are low and we worry about kids throwing things into them), but are there other longer-term strategies? Do we address them now or when we update roof (and hopefully put in solar panels)? I know there's no way to update our 1919 house to a "passive house" (in my dreams), but what other ways can one improve air flow besides leaving windows open, box fans on, and keeping shades drawn as best as possible against the sun? Oh...and I would like to also plant more trees but that's not the focus of this question....but would love some guidance on:
1) what strategies others have used;
2) what contractors deal with this sort of thing (e.g. attic people? roofers?);
3) what are price ranges for interventions?
