I have a 1959 old florida home with a flat tar and gravel roof. I been in this house for two years and the summer heat has been a ouch to my wallet. this house gets so hot the are will not shut off. The inside air temp gets higer than the a.c. thermostat setting. I am replacing the old soffit vents to a 4x6 vent. Note there is no Insulation and I have only 7 1/2 inches from celling to roof. How much if any room do I have to put blow Insulation in. Cant put in bats It would be to hard.
