I have a home that had just the small square vents at the top of ridgeline for ventilation. I added a power vent since I had poor ventilation in the attic.Then a few years went by and I had a new roof put on. The roofer had a Ridge vent installed to help out. I recently talked with another roofer and he said that a ridge vent and power vent working together is not good. Can anyone elaborate?thanks.

I wouldn't worry about it to much. Residential ventilation seems to me to be part science and some part hypothises. Have read conflicting views on the matter in trade publications.

"THEY SAY" a ventilation system should be properly designed/configured in certain ways or the "system" gets "confused".

I think between your ridge vent, and your power vent, you're probably getting fine long as you have an equal amount of inlet air comming in from soffit vents, etc.

A roof CAN be your friend
