Attic Ventilation

Written by Todd Miller on June 26, 2009 | Filed under: Home Ventilation,Misc,Roofing Answers

Q: My home 34×60,single story, red brick, colonial front, slab floor. I have vents in ceiling, living and bedrooms have cathedral ceilings on opposite ends of home. Attic ventilation is an opening on each end of the 60′ length through the shape of a birds beak, roof is 5/12 pitch. I am replacing the roofing shingles (30 year heritage). I have no soffit vents, and this area is probably covered with insulation, blown in ceiling, batt in walls. Should I consider a full length ridge vent, attic fans at gable ends? Maybe some wind turbines on back side of home. The attic is pretty hot in summer. Thanks for any suggestions

A: The best thing for attic ventilation would be to open up the soffits and put vents in them, add a ridge vent, and close off the gable end vents. Shy of doing that, I would leave the gable vents and put a turbine or two near the middle of the roof.
