Question DetailsAsked on 7/8/2015

Is a ridgeline vent sufficient to cool an entire house? An addition was added and there is a ridgeline vent.

We were told the old house was taken down to the studs and an addition added on (approx. 1,000 sq ft) added at the back of the house. The addition clearly has a ridge vent. The builders put venting around entire house on soffits but there is no ridge vent on the old part of the house. There is a tiny vent over a bedroom. We are experiencing hot temperatures on the old part of the house. Air conditioning company said it is not the system or installation of AC. New addition is cool and comfortable.

generally the rige vent helps protect the roof. it helps keep the attic cool and dry protecting the shingles from excess heat. you can add ridge vents to the areas that dont have it or you can add an attic fan.

Since you said you have soffits all around the house (assuming - verify - that you have eave openings hidden by the soffits), then the obvious solution is adding ridge vent along the rest of the ridge on the older part of the house - make a tremendous difference. If you don't have eave vents, then more of a hassle to put them in, and requires taking the soffits out to do it.

Installing a ridge vent (assuming asphalt shingle roof) should run about $5-15/LF, typically in the $10 something range, and does not affect the rest of the roof aside from the portion being worked on - they just strip the top row of shingles on each side of ridge and the cap shingles, cut through and discard a strip of sheathing on each side (about 6 inches wide) of the ridge, install the ridge vent, and put cap shingles over it if that is the selected. For a normal 50 foot or so length about 2-4 hours work for two guys. And close off the existing gable vent so it does not short-circuit the airflow.

You can find discussions on different and brands of ridge vent in the Home > Roofing link in Browse Projects, at lower left.
