Should I install a roof power vent fan while replacing roof shingles if I have soffit vents and ridge vents?

If you have soffit and ridge vent I would not recommend the power fan, If the soffits are properly vented and the insulation is not blocking the space between the roof rafters/ trusses the convection process works well and does not use electricity to operate. The fan can draw air from the ridge affecting the venting of the attic by not pulling air evenly thru the entire attic.

Thanks,
