I have a 60 year old two story 2,000 sq foot brick home. The home has a newer roof on it but they did not install a ridge vent. In the summers it gets extremely hot in the attic causing the upstairs of the house to get hot, obviously! Is it worth installing a powered attic fan in the roof considering that I will not get the cross ventilation you would get with a home that has soffits? I have considered installing soffits but there are gutters installed around the roof so there is no where to cut them in. There are however roof vents located throughout the roof. Would these provide enough ventilation if they are only located along the peak of the roof? If you recommend an attic fan is there a brand or model you recommend?
