Am reroofing now & adding ridge vent, so need to know my eave air flow. Have exposed 4x6 cedar rafters with 1x6 between them - no soffit. Each 1x6 has 3 (2" diam) holes backed with wire screen. In theory, I would think I have 3 x 6.28 sq in air flow reduced by the wire screen (50%?) per 1x6 board. The 'coons & squirrels have gotten through the screen multiple times over the years, so I've stapled a standard metal 4x16 undereave vent (air flow rated at 28 sq in each) to the backside of each 1x6. Now what do I have?
