I have a 2 story colonial built in 1980 in the Washington, DC area which has 2 A-style gable vents on each end of the attic wall. There are no soffit vents, ridge vents, or powered ventilators installed at this time. I recently removed the old insulation, air sealed the attic floor, and reinstalled the insulation. On hot days (> 72 degrees), I’ve noticed a slight odor (smells like the insulation) on the second story.
The roof was redone by the previous owners in 2008. I wasn’t prepared to install soffit vents at this time and would likely use the SmartVent when it’s time to redo the roof. For what it’s worth, there is a small 1” gap where I can see daylight in the attic where the roof deck meets the eaves. I’d like to get opinions on installing only a ridge vent to solve the odor problem? Would it be worth the effort to install the SmartVent on the existing roof?
Really appreciate the feedback as I want to get this right.
