Expert Verdict Reviewed by the SuperArbor Pro Desk

Off ridge vents are a good choice on tile roofs where ridge venting is impractical, since tile profiles often prevent a continuous ridge vent from seating properly. Place exhaust vents near the ridge high on the roof and make sure soffit or eave intake supplies at least as much net free area. Keep the vent flashing integrated with the tile underlayment so water sheds over, not under, the flange.

Roof vent installation involves working at height on tile; use fall protection and follow local building codes for attic ventilation.
