What this means for your roof
Owens Corning’s bulletin explains that wildfire-interface rules can change acceptable attic-vent locations and ember protection. It includes Austin among its examples. Applicability depends on the property and adopted local requirements, so an ordinary ventilation detail should not be assumed suitable for every site.
A useful question for your contractor
Ask the local permitting authority to confirm whether the property falls within a regulated wildfire-interface area before choosing vents.
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
