Abstract

Particular aspects represent a significant departure from pervasive prior art principal of 'continuity of nominal thickness' and coordinate dimensioning of projection elements. Certain aspects provide a realistic, viable and effective solution to solve a long-standing problem in the roof ventilator arts of how to reduce roof ventilator weight, while retaining adequate structural integrity and functionality over a reasonable service life. In preferred aspects, the inventive ventilators comprise at least one cover member surface recess area in the cover member, the surface recess area positioned, at least in part, between two spaced support members to proportionately reduce the thickness of the cover member between the two spaced support members relative to the thickness of the cover member at the respective support member extension positions to provide a selectively recessed roof ventilator affording a reduced weight while retaining structural and functional integrity.
