I need some advice from any house builder gurus out there on an issue with a finished attic having major heat issues in the summer and cold in the winter.
The house is probably 30x40 and the upstairs is a finished attack built around the 1950's. The stairway going up is open to the first floor, is drywalled, carpeted, etc. This upstairs is kind of built like a cathedral ceiling in that there is just a small cavity between the ceiling and the roof from the soffit (this house does not have any though) of the roof to the peak. There are no gable vents, no ridge vent, no soffit (because the roof basically butts right up to the outer walls) and there are 4 vents on the face of the roof which are just open to the air with a cover on top of it. This attic is heated and cooled with separate unit in the bedroom up there because there is no duct work going from the basement to the attaic. The attaic has been insulated with blow in material, but I'm not sure how great of job was because they didn't remove much or any of the drywall to get to a lot of it. In the summer time this upstairs bedroom gets so hot you would melt if you stayed up there and in the winter time it's very cold. My first thought was improper venting of the roof system because of having no eve soffit and no ridge vent so all the air is just sitting up there and baking the whole area.
Has anyone delt with this type of issue in a remodel or on a new build and if so what possible solutions are out there and would they be crazy expensive?
Thanks for any help or advice.
