Louver vents installed instead of soffit vents Knoxville, TN.
Louver vents are installed at the bottom edges of roofs to let air into the attic space. They are used instead of soffit ventilation. This project was tall but not too steep, so working near the edge was not too bad. The soffit vents had to be placed over cuts into the roof decking and shingles over the soffit vents.
The air will breathe into the roof through the soffit vents and power vents near the roof’s ridgeline.
