IB 10-inch roof vents are general-purpose vents designed to provide passive ventilation for attic and cavity spaces on low-slope and flat roof assemblies. Proper ventilation helps reduce heat buildup, moisture, and condensation, supporting long-term roof system performance.
These vents are not intended for use over exhaust pipes, including dryer, gas, chimney, bath, or kitchen vents, or any penetration carrying high-temperature exhaust, grease-laden vapors, lint, or combustion gases. Misapplication may create safety hazards, violate code requirements, and affect roof system performance or warranty coverage.
Before installation, confirm the vent location using project drawings and field conditions. Place the vent where airflow is effective and avoid areas prone to ponding water, concentrated water flow, or restricted air movement. Verify that the roof deck is clean, dry, structurally sound, and free of debris.
Cut the roof opening in accordance with IB Roof Systems details and applicable code requirements. Position the 10-inch roof vent over the opening so the vent throat is centered and the base flange lies flat without bridging or distortion. Secure the vent base to the roof deck using approved IB fasteners, ensuring every pre-punched hole receives a properly seated fastener for complete securement.
After attachment, prepare the membrane and vent base for hot-air welding in accordance with IB Roof Systems procedures. Weld the base seam to create a continuous minimum 1-1/2-inch welded seam around the flashing. The weld must be uniform and free of voids, wrinkles, skips, or contamination.
Once the weld has cooled, inspect and probe all seams and laps. Any deficiencies must be marked and re-welded or repaired in accordance with IB Roof Systems repair procedures. Complete the installation by clearing debris, confirming the vent opening is unobstructed, and documenting the work as required.
