Start the installation of the roll of US RoofVent even at the gable edge drip edge of the roof with fabric edge(aka: lift edge) against the lower fascia drip edge WITH the smoother side of the roof vent facing towards the sky. This will show the nailing line at 2.5” up from the lift edge of the US RoofVent. The rougher side of the roof vent is against the roof deck. Nail the US RoofVent along the lift edge nail line every 6” - 8” while nailing the no-lift upper edge every 12”. Begin and end within 1.5” of the start and end of each roll. Nails should be a minimum of 1.5” long, enough to penetrate the entire thickness of the wood roof deck. Wrap the remaining end fabric neatly over the roof vent ensuring it is even with the drip edge along the gable rake edge. Refer to STEP 4 for wrapped fabric detail. Nail the fabric with two nails, one high and one low, as shown.
