I'm having a 1st floor back porch of a 2 story victorian enclosed as a breakfast nook. Exterior is complete, roof is resheathed, shingled and flashed into 2nd floor siding. Soffit vents installed. Interior still gutted. Ceiling will have vapor barrier and insulation.
Question: How do I vent this roof with no ridge? Is a passive vent in the 1/2 gable peak enough? Please help.
