With gable overhangs already framed out on the lower shed-roof portion of the addition, Maine Passive House contractor Jesper Kruse and carpenter Todd place Pro Clima Mento Plus fabric at the roof eave.
Jesper Kruse staples fabric to the I-joist rafter at the seam. The Mento Plus fabric is not the main drainage plane for this roof assembly (which will be capped with OSB and shingles over an air space). Even so, Kruse installs the fabric air-tight and water-tight.
