If you have an attic, does it have any ventilation? Ventilating the
attic space has a few advantages:
1. It will increase the longevity of your asphalt shingle roof.
2. It will keep the attic cooler, and therefore the living space under
it will be cooler.
I have a similar problem in my 2 story house. In hot weather, the first
floor is a lot cooler. I can combat this by opening windows upstairs and
by occasionally using a big box fan, usually in a window, blowing in.
Especially in the evening, this cools off a room by 5-10 degrees very
My bedroom is upstairs, and in all but the hottest weather, having a
couple of screened windows open makes it comfortable to sleep. If it
gets a bit cool, I lower a shade or two or even close a window and go
back to sleep.
